Half-Size, Low-costGlobal Embedded Modem

Description

The Cermetek XE5690H is a complete, global modem in a compact, surface-mount module. It covers less than half the board space of the leading competitor and is less than half as thick as well.

Cermetek includes user transferable FCC Part 68 registration with every modem module. This allows the system designer to add a modem to a process control, remote monitoring, point-of-sale, or remote diagnostic system without Part 68 certification.

Only Cermetek offers embedded modems in leadless, surface-mount form. As a result, the XE5690H is not only substantially smaller than the competition but the surface-mount package frees additional space on the bottom of the application board for routing traces or placing components. This space efficient design allows the development engineer greater flexibility in placement of the modem within the host system.

Pin Descriptions

PIN	NAME	DESCRIPTION
1	Tip	The Ring and Tip signals connect the modem to the telephone line. FCC Part 68 Rules require a 1500 volt isolation barrier between the telephone line and all other circuits. This isolation must be preserved throughout the system. The telephone company places a DC “Battery” voltage across Tip and Ring on public switched telephone lines. The XE5690H operates regardless of the polarity of this voltage. The “Battery” voltage drives up to 100 milliampere of DC loop current. UL60950 requires minimum creepage and clearances distances between the Tip and Ring and all other circuits. Clearance is the shortest distance between conductive circuits; creepage is the distance between conductive points along the surface
2	Ring	The Ring and Tip signals connect the modem to the telephone line. FCC Part 68 Rules require a 1500 volt isolation barrier between the telephone line and all other circuits.

Clearance is the shortest distance between conductive circuits; creepage is the distance between conductive points along the surface.
PIN	NAME	DESCRIPTION
3	/DSR	/DSR is an active low output from the modem and is forced to the active condition.
4	/DCD	/DCD is an active low output from the modem. An active /DCD indicates the presence of a valid carrier signal. The AT&C command controls when the XE5690H asserts /DCD.
5	/DTR	/DTR is an active low input to the modem. An active /DTR signals the terminal is available for communications. The AT&D command determines how the modem interprets activity on /DTR.
6	/RI	The /RI signal reports on the presence of an incoming ring signal. When a ring occurs across Tip and Ring, the /RI output goes low and toggles with the cadence of the ring signal.
7	SPKR	SPKR provides a Pulse Width Modulated version of the signal on Tip and Ring allowing connection of a speaker to the modem to monitor modem operations. The recommended speaker circuit is shown on Page 9 of this data sheet. The signal on SPKR is controlled by the ATL and ATM commands.
8	Ground	Ground provides the reference voltage for all host interface signals.
9	/TXD	/TXD provides the path for transmitted data and modem commands to be passed from the host controller to the modem.
10	/RXD	/RXD provides the path for received data and modem responses to be sent from the modem to the host controller.
11	/RESET	/RESET is an active low input which initiates a modem hardware reset. /RESET must be active for a minimum of 100 milliseconds for a proper modem reset sequence. No external reset is required; if none is used the RESET signal should be left open.
12	/CTS	/CTS is an active low output from the modem. When hardware flow control is set, the modem asserts /CTS to indicate that it can accept data from the terminal equipment on /TXD.
13	/INT	/INT provides an active low hardware interrupt signal from the XE5690H. The operation of this interrupt pin is programmable using the modem’s register U70.
14	VCC	VCC provides 3.3 volt power to the modem.
15	/RTS	/RTS is an active low input to the modem. When hardware flow control is set, an active /RTS indicates to the modem that the host has data to send.
16, 17	N/C	These pins are provided only for mechanical stability. These pins must remain unconnected.

XE5690H Design Notes

The following design notes are intended to assist the developer in achieving maximum utility from the XE5690H modem module.

XE5690H Shared Line Features

The XE5690H can monitor telephone line conditions before, after and during calls. This allows the system to avoid conflicts with other equipment connected to the same telephone line. There are two line monitoring modes; Connect Detect and Handset Interrupt.

Connect Detect:

Connect Detect is active when the XE5690H is on-hook. With AT%V2 selected the XE5690H verifies the availability of the telephone line by checking the DC loop voltage before going off-hook for dialing or answering a call. The nominal value of loop voltage is stored in register U85, typically 48 volts. The XE5690H can detect either the lack of an installed telephone line or that the connected line is in use.

NO LINE If the telephone line is disconnected from the modem, the voltage on Tip and Ring will be zero. If the modem reads a DC loop voltage of 3 volts or less, the modem will not go off-hook and will issue the “NO LINE” response.

LINE IN USE If a telephone handset, fax machine or other piece of equipment connected to the telephone line is in use, the DC loop voltage will drop. Typically the DC loop voltage will drop to around 10 volts while the telephone line is in use. If the modem sees a DC loop voltage between 3 volts and 85% of the nominal loop voltage (41 volts typical), the modem will not go off-hook but will transmit the “LINE IN USE” response

If neither the “NO LINE” or “LINE IN USE” conditions is true, the XE5690H goes off-hook and completes the original command.

Handset Interrupt:

The Handset Interrupt feature permits the modem to yield the telephone line to other equipment connected to the same line. This prevents the XE5690H from blocking outgoing emergency calls when the line is shared as in a residential application including set top boxes and automated meter readers. For Handset Interrupt the modem monitors the loop current while it is off-hook. The Loop current will drop if a piece of equipment connected to the same telephone line goes off-hook. The Handset Interrupt function is controlled by registers U77 and U78. U78 defines when the Handset Interrupt is operable, and U77 allows the operator to configure the modem to disconnect immediately upon detecting another piece of equipment on the telephone line.

U77: Bit 11 of U77 sets the XE5690H to automatically disconnect any time another piece of equipment connects to the line while the modem is off-hook. This configuration is recommended when the modem will be sharing a line with a telephone handset as it provides the quickest access to the phone line for emergency calls. If U77 bit 11 is not set, then U70 bit 10 should be. U70 bit 10 causes the modem to provide an interrupt when the off-hook condition of the other equipment is detected.

U78 Bits 14 and 15 of U78 control when the Handset Interrupt will be active.

• If both bits are reset, Handset Interrupt is disabled.

• If only bit 14 is set, the modem monitors the line for a Handset Interrupt after dialing.

• If only bit 15 is set, the XE5690H activates Handset Interrupt when the timer set by bits 0 to 7 expires. Bits 0-7 set this timer in 500 millisecond increments.

• If both bits 14 and 15 are set, the modem starts monitoring for a Handset Interrupt after the modem handshake is completed.

XE5690H AT Commands

The XE5690H uses "AT" commands for configuration and control. This section describes the AT command format and lists the commands, registers and result codes.

Command Mode: The XE5690H enters command mode on power-up, reset, a lost connection, or receipt of the escape code. In command mode the modem accepts commands from the host on transmit data. Appropriate result codes are returned on received data.

Command Line Format

AT commands follow a strict format. Each command line, except A/, begins with the prefix AT. The "A" and "T" may be both upper case or both lower case but cannot be of different cases. The modem determines data rate of the host equipment by measuring the width of the incoming bits of the “A” and “T.”

Multiple commands may be combined into a single command line of up to 48 characters. Commands are executed in the sequence they appear upon receipt of a carriage return. Spaces inserted into the command line are not placed in the buffer.

The command line can be edited with a backspace before it is executed. The backspace erases the previous character in the command line. Register S5 allows the user to select a character other than backspace to edit the command line.

If the command buffer overflows, the modem issues an "ERROR" result code, and the command line is not executed. Register S3 allows the user to select a character other than a carriage return to terminate the command line.

Re-Execute Last Command - The A/ command causes the modem to re-execute the last command line. This is the only command which does not require the "AT" prefix.

Omitted Parameters - Most commands include a parameter which determines how the functions will be set. When the command parameter is omitted from the command string, it is assumed to be a 0.

Escape Characters - A 3 character escape sequence may be entered to switch the modem into command mode while on line. The escape character, set by Register S2, must be entered 3 times in succession to execute the escape. An AT command must then be entered within the period defined by S12 to enter command mode. The default escape sequence is "+++."

Result Codes - The modem issues a result code after each action. Result codes may be sent as full words, one or two digit numeric codes, or may be disabled all together. Each result code ends with a carriage return when numeric result codes are chosen. When full word result codes are chosen, a Line Feed and Carriage Return precede and follow each result code.

XE5690H Boot Command

The XE5690H allows a default command string to be automatically loaded into the modem on power-up or modem reset. A series of commands loads the default command string in Hex form into the modem’s EEPROM. The EEPROM has 256 bytes available for command storage.

The sequence to load the default commands into EEPROM must begin with the Boot command and end with a double carriage return. All commands are loaded into the EEPROM in Hex form beginning with address M0000. Up to 8 addresses may be loaded with each command in the sequence.

The following example uses a typical configuration for an embedded application. ATE0 disables command echo; ATQ1 disabled modem responses, and ATS0=1 sets the modem to automatically answer on the first ring. This sequence is loaded into the modem EEPROM with the Boot command using the command sequence below. This places the modem into the desired configuration each time power is applied or the modem is reset

Warning: The XE5690H could be rendered useless by improper use of the Boot command.
