description
The TMS370C036, TMS370C736, and SE370C736 devices are members of the TMS370 family of single-chip
8-bit microcontrollers. Unless otherwise noted, the term TMS370Cx36 refers to these devices. The TMS370
family provides cost-effective real-time system control through advanced peripheral-function modules and
various on-chip memory configurations.
The TMS370Cx36 family of devices uses 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
TMS370Cx36 devices attractive for system designs for automotive electronics, industrial motors, computer
peripheral controls, telecommunications, and consumer applications.
All TMS370Cx36 devices contain the following on-chip peripheral modules:
Programmable acquisition and control timer (PACT)
–
Asynchronous mini SCI
–
PACT watchdog timer
Serial peripheral interface (SPI)
Eight channel, 8-bit analog-to-digital converter 1 (ADC1)
