Introduction
●This section describes the main features, gives a brief functional overview of the TMS320VC5471, lists the pin assignments, and provides a signal description table. The data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data section describing the available packaging.
●Description
●The TMS320VC5471 integrates a DSP subsystem based on the TMS320C54x architecture and a RISC microcontroller subsystem based on the ARM7TDMI core as shown in Figure 2--1. The DSP subsystem includes 72K x 16-bit SRAM, a timer, a DMA controller, an external memory interface, and two McBSPs. The MCU subsystem includes three timers, general-purpose I/O, an external memory interface, and an Ethernet (10/100Base-T) interface with a media-independent interface (MII) port.
