overview

The TMS370 family consists of very large scaled integration (VLSI), 8-bit, complementary metal oxide

semiconductor (CMOS) microcontrollers with on-chip EEPROM storage and peripheral-support functions.

These devices offer superior performance in complex, real-time control applications in demanding

environments and are available in mask-programmable ROM and EPROM.

In a continual effort to improve its products, Texas Instruments has added new, more robust features to the

TMS370 family of devices that are designed to enhance performance and enable new application technologies.

These added features include new watchdog modes and low-power modes for mask-ROM devices. All family

members are software compatible, so that many existing applications can be run on the improved devices

without modification of software. (Refer to the associated data sheets for more information on compatibility.)

In expanding its powerful TMS370 family of microcontrollers, TI

™ offers many new configurable devices for

specific applications. As microcontrollers have evolved, TI has added multiple peripheral functions to chips that

originally had only a central processing unit (CPU), memory, and I/O blocks. Now, with the high-performance,

software-compatible TMS370 microcontrollers, over 130 standard products are available. Also, up to

27 function modules can be used to configure a new device quickly, easily, and cost-effectively for any

applications.

The TMS370 family is supported fully by TI development tools that facilitate simplified software development

for prompt market introduction of new products. These tools include an assembler, an optimizing C compiler,

a linker, a C source debugger, a design kit, a starter kit, and a third-party microcontroller programmer from

BP Microsystems. All of these tools work together by using an IBM

™-compatible personal computer (PC) as

the host and the central control element. This allows the user to select the host computer and text management

as well as editing tools according to system requirements.

Additionally, the TMS370 in-circuit emulator [XDS

™—extended development support, and CDT370 compact

development tool (CDT

™)] allows the user to immediately begin designing, testing, and debugging the system

upon specification. The reason for this is straightforward: the emulator itself is modular and configurable,

thereby eliminating the need to produce a new emulator for each TMS370 configuration.

typical applications

The TMS370 family of devices is the ideal choice for the applications shown in Table 1 because the newly added

features (like the addition of multiple peripheral functions per device) have expanded the TMS370 family of

microcontrollers, enhanced its performance, and opened up new application technologies.
