DATA SHEET
MOS INTEGRATED CIRCUIT
µPD30500, 30500A, 30500B
VR5000TM, VR5000ATM, VR5000BTM
64-BIT MICROPROCESSOR
DESCRIPTION
The µPD30500 (VR5000), µPD30500A (VR5000A), and µPD30500BNote (VR5000B) are a high-performance, 64-
bit RISC (Reduced Instruction Set Computer) type microprocessors employing the RISC architecture developed by
MIPSTM Technologies Inc.
The instructions of the VR5000, VR5000A, and VR5000B are compatible with those of the VR3000TM Series and
VR4000TM Series and higher, and completely compatible with those of the VR10000TM. Therefore, present
applications can be used as they are.
Note Under development
Detailed functions are described in the following manual. Be sure to read the manual when
designing your system.
