TMS320LC541B - Floating-Point Digital Signal Processor

Download the TMS320LC541B datasheet PDF. This datasheet also covers the TMS320C541 variant, as both devices belong to the same floating-point digital signal processor family and are provided as variant models within a single manufacturer datasheet.

Description

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses.
