DSP Fixed-Point 16Bit 200MHz 200MIPS 144Pin BGA MICROSTAR

Introduction

This section describes the main features, gives a brief functional overview of the TMS320VC5421, lists the pin assignments, and provides a signal description table. This data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data about the available packaging.

Description

The TMS320VC5421 fixed-point digital signal processor DSP is a dual-core solution running at 200-MIPS performance. The 5421 consists of two DSP subsystems capable of core-to-core communications and a 128K-word zero-wait-state on-chip program memory shared by the two DSP subsystems. Each subsystem consists of one 54x DSP core, 32K-word program/data DARAM, 32K-word data SARAM, 2K-word ROM, three multichannel serial interfaces, xDMA logic, one timer, one APLL, and other miscellaneous circuitry.
