Description

The TMS470R1A256(1) devices are members of the Texas Instruments TMS470R1x family of general-purpose 16/32-bit reduced instruction set computer (RISC) microcontrollers. The A256 microcontroller offers high performance utilizing the high-speed ARM7TDMI 16/32-bit RISC central processing unit (CPU), resulting in a high instruction throughput while maintaining greater code efficiency. The ARM7TDMI 16/32-bit RISC CPU views memory as a linear collection of bytes numbered upwards from 0. The TMS470R1A256 utilizes the big-endian format where the most significant byte of a word is stored at the lowest numbered byte and the least significant byte at the highest numbered byte.

High-end embedded control applications demand more performance from their controllers while maintaining low costs. The A256 RISC core architecture offers solutions to these performance and cost demands while maintaining low power consumption.
The A256 device contains the following:
· ARM7TDMI 16/32-Bit RISC CPU
· TMS470R1x system module (SYS) with 470+ enhancements
(1) Throughout the remainder of this document, the TMS470R1A256 device name will be referred to as either the full device name, TMS470R1A256, or as A256.
