† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. Unless otherwise noted, all voltage values are with respect to VSS.
2. Electrical characteristics are specified with all output buffers loaded with specified IO current. Exceeding the specified IO current in any buffer can affect the levels on other buffers.
DescriptionThe 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:
·Serial peripheral interface (SPI)
·One 24-bit general-purpose watchdog timer
·One 16-bit general-purpose timer with an 8-bit prescaler
