IC Description
DW370ASM* (Micro-controller for Non-Teletext Model)
=TMS370C08A05 ( TI Type No.)
(1) General Description
The TMS370C08A05 devices are members of the cMCU370 family single-chip microcontrollers.
The cMCU370 family provides cost effective real-time system control through use of the PRISM methodology.
The PRISM methodology modular fabrication process integrates analog, digital, linear and power technologies on a
single chip, thereby maximizing the total integration strategy.
The TMS370C08A05 devices are designed with the high-performance 8-bit TMS370C8 CPU.
Features of the ‘C8 CPU and system module as implemented on this device include three CPU registers (stack
pointer, status register, and the program counter), two external interrupts, reset, memory mapped control registers.
