V810^TM
32-BIT MICROPROCESSOR
The µPD70732 (a.k.a. V810) microprocessor is NEC’s first microprocessor of the V810 family^TM for embedded
control applications.
The V810 employs a RISC architecture for embedded control applications. This product has high-speed real
time response, high-speed integer operation instruction, bit string instruction, floating-point operation instruction,
and significantly high cost performance is realized for applications such as facsimile, digital PPC, word processor,
image processor, real time control device, etc.
The functions are described in detail in the following User’s Manuals, which should be read before
starting design work.
• V805^TM, V810 User’s Manual Hardware : U10661E
• V810 Family User’s Manual Architecture : U10082E
