µPD70732
V810TM
32-BIT MICROPROCESSOR
The µPD70732 (a.k.a. V810) microprocessor is NEC’s first microprocessor of the V810 familyTM 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.
• V805TM, V810 User’s Manual Hardware : U10661E
• V810 Family User’s Manual Architecture : U10082E
Features
High-performance 32-bit architecture for embedded control application
• 32-bit separate address/data bus
• 1-Kbyte cache memory
• Pipeline structure of 1 clock pitch
• 16-bit fixed instructions (with some exceptions)
• 32-bit general-purpose registers: 32
• 4-Gbyte linear address space
• Register/flag hazard interlocked by hardware
Dynamic bus sizing function (16 bits)
16-bit bus fixing function
16-bit bus system can be configured.
Instructions ideal for various application fields
• Floating-point operation instructions (based upon IEEE754 data format)
• Bit string instructions
16 levels of high-speed interrupt responses
Clock can be stopped by internal static operation
Maximum operating frequency: 16/20/25 MHz
Low voltage: VDD = 2.7 to 3.6 V (Max. 16 MHz)
VDD = 2.2 to 3.6 V (Max. 10 MHz)
Small package versions available (14 x 14 mm fine-pitch TQFP)
