Introduction
The TMS320x240x series of devices are members of the TMS320 family of
digital signal processors (DSPs) designed to meet a wide range of digital motor
control (DMC) and other embedded control applications. This series is based
on the ’C2xLP 16-bit, fixed-point, low-power DSP CPU, and is complemented
with a wide range of on-chip peripherals and on-chip ROM or flash program
memory, plus on-chip dual-access RAM (DARAM).
This reference guide describes the following four ’240x devices: ’2407, ’2406,
’2404, and ’2402. These low-cost DSPs are intended to enable multiple appli-
cations for a nominal price.
This chapter provides an overview of the current TMS320 family, describes the
background and benefits of the ’240x DSP controller products, and introduces
the ’2407, ’2406, ’2404, and ’2402 devices.
Throughout this book, all four devices are collectively referred to as ’240x
devices.
