TMS320VC5421 is a 200MIPS dual-core digital signal processor produced by Texas Instruments
The TMS320VC5421 digital signal processor from Texas Instruments is a dual‑core, fixed‑point device delivering up to 200 MIPS performance. Each core includes a 40‑bit barrel shifter, 40‑bit accumulators, a 17‑bit × 17‑bit parallel multiplier, two 8‑element FIFOs, twelve DMA channels, three multichannel serial interfaces, and a 16‑bit host‑port interface. The device provides 128 K‑word × 16‑bit shared on‑chip program memory and 512 K‑word × 16‑bit extended program emulation space.
The DSP is offered in 144‑pin thin‑quad flat‑pack (TQFP) and 144‑pin MicroStar ball‑grid‑array (BGA) packages, both pin‑compatible with the TMS320VC5420. Detailed pin‑assignment tables for the PGE (TQFP) and GGU (BGA) packages are included, along with mechanical dimensions and an important notice covering warranty and critical‑application usage.
