TMS320LF/LC240xA DSP ControllersReference Guide
The TMS320Lx240xA series of devices are members of the TMS320_ familyof digital signal processors (DSPs) designed to meet a wide range of digitalmotor control (DMC) and other embedded control applications. This series isbased on the C2xLP 16-bit, fixed-point, low-power DSP CPU, and is complementedwith a wide range of on-chip peripherals and on-chip ROM or flash programmemory, plus on-chip dual-access RAM (DARAM).
This reference guide describes the following 240xA devices: 2407A, 2406A, 2404A, 2403A, 2402A, and 2401A.
This chapter provides an overview of the current TMS320 family, describes thebackground and benefits of the 240xA DSP controller products, and introducesthe 240xA devices. These low-cost DSPs are intended to enable multipleapplications for a nominal price.
Devices within a generation of a TMS320 platform have the same CPU structurebut different on-chip memory and peripheral configurations. Spin-offdevices use new combinations of on-chip memory and peripherals to satisfya wide range of needs in the worldwide electronics market. By integratingmemory and peripherals onto a single chip, TMS320 devices reduce systemcosts and save circuit board space.
