TMS320VC5420 is a 200-MIPS dual-core fixed-point digital signal processor (DSP) produced by Texas Instruments.
The TMS320VC5420 fixed‑point digital signal processor features a dual‑core architecture capable of up to 200 MIPS performance. Each core includes a 40‑bit barrel shifter, 40‑bit accumulators, parallel multiply‑accumulate units, and a rich set of on‑chip peripherals such as DMA, multichannel buffered serial ports, and a 16‑bit host‑port interface.
The device is offered in two package types – a 144‑pin ball‑grid array (GGU) and a 144‑pin thin‑quad flat‑pack (PGE) – with detailed pin‑assignment tables. Mechanical drawings, absolute maximum ratings, and recommended operating conditions are provided, along with an important notice on warranty and product availability.
