Cautions 1. Do not connect an output (or input/output) pin of an IC device directly to any other output (or input/output) pin of the same device. Do not connect the VDD or VCC pin of an IC device directly to its GND pin or a ground. Note, however, that these restrictions do not apply to the highimpedance pins of an external circuit, whose timing has been specifically designed to avoid output collision. 2. Absolute maximum ratings are rated values, beyond which physical damage may be caused to the product; if the rated value of any of the parameters in the above table is exceeded even momentarily, the quality of the product may deteriorate. Always use the product within its rated values, therefore. For IC products, normal operation and quality are guaranteed only when the ratings and conditions described under the DC and AC characteristics are satisfied.


Description

The mPD70501 (V831) is a 32-bit RISC microprocessor for embedded control applications, with a high-performance 32-bit V830TM processor core and many peripheral functions such as a DRAM/ROM controller, 4-channel DMA controller, real-time pulse unit, serial interface, and interrupt controller.

In addition to high interrupt response speed and optimized pipeline structure, the V831 offers sum-of-products operation instructions, concatenated shift instructions, and high-speed branch instructions to realize multimedia functions, and therefore, mPD70501 can provide high performance in multimedia systems such as internet/intra-net systems, car navigation systems, high-performance televisions, and color FAXes.

Detailed explanations of the functions, etc. mPD70501 are given in the following user's manuals. Be sure to read the manuals before designing your systems.
