TMS470 Microcontrollers: 32-Bit RISC ARM7TDMI ® -Based
75
➔
Building upon the success of its popular
MCU products, TI—the largest,
most experienced licensee of
Advanced RISC Machines (ARM ® )
Ltd. cores—is now offering the
TMS470 platform of microcontrollers
to the mass market. Having gained
extensive experience through its
development in wireless, imaging and
industrial markets, TI is a proven supplier
of ARM core-based devices.
Architecture
The TMS470 is derived from the 32-
bit ARM7TDMI ® core.* This industrystandard
architecture includes two
instruction sets—32-bit instructions
for fast execution and 16-bit instructions
for high code density. It allows
unlimited switching between instruction
sets and also provides run-time
decompression. This gives the designer
ultimate flexibility when designing
for high-speed operation or highdensity
code.
Product Portfolio
The TMS470 microcontroller platform
has devices ranging from 64 KB to 1 MB
of Flash memory and a wide variety of
intelligent peripherals including up to
32 timer channels, 16 channels of 10-
bit analog-to-digital converters and a
variety of communication interfaces.
TMS470 microcontrollers are targeted
for applications requiring the highest
levels of performance and quality with
the flexibility of a scalable architecture
and a rich peripheral set. Typical
applications include industrial systems,
medical instrumentation, consumer
electronics, data processing and many
other general-purpose embedded
applications.
TI’s TMS470 ARM7TDMI-based MCUs
bring you a complete microcontroller
solution with quality, reliability and
support.
