description

The TCM8002 provides the data transceiving, data processing, and SAT (supervisory audio tone) functions for

the AMPS (advanced mobile phone service) and TACS (total access communications system) cellular

telephone standards. A highly integrated device, the TCM8002 includes a number of additional functions that

are helpful in the implementation of the typical cellular telephone. These extra functions include a watchdog

timer, which is normally external to the telephone microcontroller, and two 8-bit- and one 4-bit-wide

user-programmable general-purpose input/output ports. These can be used to provide port expansion for the

microcontroller. An 8-bit counter/timer for user-defined purposes is also included.

To facilitate the application of the TCM8002 and to minimize the number of connections, a single serial interface

tothemicrocontrollerisusedforcontrolling, receiving, andtransmittingdata. Thereisalsoadedicatedinterface,

including a compatible clock signal, to the companion TCM8010 audio processor that performs most of the

audio processing required in a cellular telephone. Additional outputs are also provided for interfacing to other

audio processors.

The TCM8002 is built using a low-power CMOS process and operates with a 5-V or 3.3-V power supply. When

used in conjunction with the TCM8010, a unique and very compact low-power solution for AMPS/TACS

baseband processing in 5-V and 3-V systems is realized.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
