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 to the Microcontroller is used for controlling, receiving, and transmitting data. There is also a dedicated Interface 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. By Texas Instruments
