Unless otherwise noted, the term TMS370Cx32 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 TMS370Cx32 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 TMS370Cx32 devices attractive for system designs for automotive electronics, industrial motors, computer peripheral controls, telecommunications, and consumer applications.
All TMS370Cx32 devices contain the following on-chip peripheral modules:
Programmable acquisition and control timer (PACT)
Asynchronous mini SCI
PACT watchdog timer
Eight channel, 8-bit analog-to-digital converter 1 (ADC1)
The 8K bytes of mask-programmable ROM in the associated TMS370Cx32 devices are replaced in the TMS370C732A with 8K bytes of EPROM. All other available memory and on-chip peripherals are identical except for the TMS370C332A which does not have EEPROM memory. The OTP (TMS370C732A) and reprogrammable (SE370C732A) devices are available. The TMS370Cx32 OTP device is available in a plastic package. This microcontroller is effective to use for immediate production updates for other members of the TMS370Cx32 family or for low-volume production runs when the mask charge or cycle time for the low-cost mask ROM devices is not practical.
The SE370C732A has a windowed ceramic package to allow reprogramming of the program EPROM memory during the development/prototyping phase of design. The SE370C732A device allows quick updates to breadboards and prototype systems while iterating initial designs.The TMS370Cx32 family provides two low-power modes (STANDBY and HALT) for applications where low-power consumption is critical. Both modes stop all CPU activity (that is, no instructions are executed). In the STANDBY mode, the internal oscillator, the PACT counter, and PACT's first command/definition entry remain active. This allows the PACT module to bring the device out of STANDBY mode. In the HALT mode, all device activity is stopped. The device retains all RAM data and peripheral configuration bits throughout both low-power modes.
The TMS370Cx32 features advanced register-to-register architecture that allows direct arithmetic and logical operations without requiring an accumulator (for example, ADD R24, R47; add the contents of register 24 to the contents of register 47 and store the result in register 47). The TMS370Cx32 family is fully instruction-set-compatible, providing easy transition between members of the TMS370 8-bit microcontroller family.
The TMS370Cx32 has a PACT module that acts as a timer coprocessor by gathering timing information on input signals and controlling output signals with little or no intervention by the CPU. The coprocessor nature of this module allows for levels of flexibility and power not found in traditional microcontroller timers.
The TMS370Cx32 family provides the system designer with an economical, efficient solution to real-time control applications. The PACT compact development tool (CDTE) solves the challenge of efficiently developing the software and hardware required to design the TMS370Cx32 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. Precise real-time, in-circuit emulation and extensive symbolic debug and analysis tools ensure efficient software and hardware implementation as well as a reduced time-to-market cycle. The TMS370Cx32 family together with the TMS370 PACT CDT370, BP programmer, starter kit, software tools, the SE370C732A reprogrammable devices, comprehensive product documentation, and customer support provide a complete solution to the needs of the system designer.
