• Manufacturer: AD [Analog Devices]

DESCRIPTION
The TMS470R1B512
general-purpose16/32-bit reduced instruction set computer (RISC) microcontrollers. The B512 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 zero. The B512 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 B512 RISC core architecture offers solutions to these performance and cost demands while
maintaining low power consumption.
The B512 device contains the following:
The functions performed by the 470+ system module (SYS) include:
This data sheet includes device-specific information such as memory and peripheral select assignment, interrupt
priority, and a device memory map. For a more detailed functional description of the SYS module, see the
TMS470R1x System Module Reference Guide (literature number SPNU189). For a more detailed functional
description of the IEM module, see the TMS470R1x Interrupt Expansion Module (IEM) Reference Guide
(literature number SPNU211). For a more detailed functional description of the DMA module, see the
TMS470R1x Direct Memory Access (DMA) Controller Reference Guide (literature number SPNU194).
The B512 memory includes general-purpose SRAM supporting single-cycle read/write accesses in byte,
half-word, and word modes.
