TMS320C6421ZDU7

Digital Signal Processor Dsp Overview

The TMS320C6421ZDU7 is a fixed-point digital signal processor from the Texas Instruments TMS320C642x series. It features a C64x+ DSP core operating at a maximum clock frequency of 400 MHz. The device utilizes a 376-pin BGA package and supports a 32-bit word size with an integrated cache architecture. It operates with a nominal supply voltage of 1.05V at 350MHz or higher frequencies, while also supporting operation at other specified voltage levels. The processor includes boundary scan capabilities and a 22-bit address bus width.
