This section describes the main features, gives a brief functional overview of the TMS320VC5470, 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 TMS320VC5470 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 ncludes 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, and an external memory interface.
