description

The TMS370C032A, TMS370C332A, TMS370C732A, and SE370C732A devices are members of the TMS370

family of single-chip 8-bit microcontrollers. Unless otherwise noted, the term TMS370Cx32 refers to these

devices. The TMS370 family provides cost-effective real-time system control through integration of advanced

peripheral-function modules and various on-chip memory configurations.

The TMS370Cx32 family of devices is implemented using high-performance silicon-gate CMOS EPROM and

EEPROM technologies. Low-operating power, wide-operating temperature range, and noise immunity of

CMOS technology coupled with the high performance and extensive on-chip peripheral functions make the

TMS370Cx32 devices attractive for system designs for automotive electronics, industrial motors, computer

peripheral controls, telecommunications, and consumer applications.

All TMS370Cx32 devices contain the following on-chip peripheral modules:

D Programmable acquisition and control timer (PACT)

–

Asynchronous mini SCI

–

PACT watchdog timer

D Eight channel, 8-bit analog-to-digital converter 1 (ADC1)
