description
The TMS370C010, TMS370C012, TMS370C311, TMS370C310, TMS370C312, TMS370C712, and
SE370C712 devices are members of the TMS370 family of single-chip 8-bit microcontrollers. Unless otherwise
noted, the term TMS370Cx1x 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 TMS370Cx1x 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
TMS370Cx1x devices attractive for system designs for automotive electronics, industrial motors, computer
peripheral controls, telecommunications, and consumer applications.
All TMS370Cx1x devices contain the following on-chip peripheral modules:
D Serial peripheral interface (SPI)
D One 24-bit general-purpose watchdog timer
D One 16-bit general-purpose timer with an 8-bit prescaler
