† 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 TMS370C002, TMS370C302, TMS370C702, and SE370C702 devices are members of the TMS370 family of single-chip 8-bit microcontrollers. Unless otherwise noted, the term TMS370Cx0x 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 TMS370Cx0x 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 TMS370Cx0x devices attractive in system designs for automotive electronics, industrial motors, computer peripheral controls,telecommunications, and consumer applications.
All TMS370Cx0x devices contain the following on-chip peripheral modules:
· Serial communications interface 1 (SCI1)
· One 16-bit general-purpose timer with an 8-bit prescaler
· One 24-bit general-purpose watchdog timer
Table 1 provides a memory configuration overview of the TMS370Cx0x devices.
The TMS370Cx0x family provides the system designer with an economical, efficient solution to real-time control
applications. The TMS370 family compact development tool (CDTTM) solves the challenge of efficiently developing the software and hardware required to design the TMS370Cx0x into an ever-increasing number of complex applications. The application source code can be written in assembly and C-language, and the output code can be generated by the linker. The TMS370 family CDT development tool can communicate through a standard RS-232-C interface with an existing personal computer. This allows the use of the personal computer editors and software utilities already familiar to the designer. The TMS370 family CDT emphasizes ease-of-use through extensive menus and screen windowing so that a system designer with minimal training can begin developing software. Precise real-time in-circuit emulation and extensive symbolic debug and analysis tools ensure efficient software and hardware implementation as well as reduced time-to-market cycle.
The TMS370Cx0x family together with the TMS370 family CDT370, design kit, starter kit, software tools, the SE370C712 reprogrammable devices, comprehensive product documentation, and customer support provide a complete solution to the needs of the system designer.
