DESCRIPTION
The TMS470R1A64
eral-purpose16/32-bit reduced instruction set computer (RISC) microcontrollers. The A64 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 high code efficiency. The ARM7TDMI 16/32-bit RISC CPU views
memory as a linear collection of bytes numbered upwards from 0. The TMS470R1A64 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.
TMS470R1A64
16/32-Bit RISC Flash Microcontroller
SPNS099–NOVEMBER 2004
A.
GIOA[0]/INT0 (pin 23) is an input-only GIO pin.
(1)
device is a member of the Texas Instruments TMS470R1x family of gen-
High-end embedded control applications demand more performance from their controllers while maintaining low
costs. The A64 RISC core architecture offers solutions to these performance and cost demands while
maintaining low power consumption.
The A64 device contains the following:
ARM7TDMI 16/32-Bit RISC CPU
TMS470R1x system module (SYS) with 470+ enhancements
64K-byte Flash
4K-byte SRAM
