PD705101
DESCRIPTION
The
μ
PD70501 (V831) is a 32-bit RISC microprocessor for embedded control applications, with a high-performance
32-bit V830
TM
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, 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. are given in the following user’s manuals. Be sure to read the
manuals before designing your systems.
