DESCRIPTION

The μPD30121 (VR4121) is one of NEC’s VR SeriesTM RISC (Reduced Instruction Set Computer) microprocessors and is a high-performance 64-/32-bit microprocessor employing the MIPSTM RISC architecture.

The VR4121 uses the high-performance, super power-saving VR4120TM as the CPU core, and has many peripheral functions such as a DMA controller, software modem interface, serial interface, keyboard interface, IrDA interface, touch panel interface, real-time clock, A/D converter, and D/A converter. Configured with these functions, the VR4121 is suitable for high-speed battery-driven portable information systems. The external memory bus width can be selected from 32 bits and 16 bits, realizing high-speed data transfer.

FEATURES

? Employs 64-bit MIPS architecture

? Conforms to MIPS III instruction set (deleting FPU, LL, LLD, SC, and SCD instructions)

? Optimized 6-stage pipeline

? Supports MIPS16 instruction set

? Supports high-speed product-sum operation instructions

? Supports four types of operating modes, enabling more effective power-consumption management

? Internal maximum operating frequency: 131/168 MHz

? On-chip clock generator

? Address space physical: 32 bits

virtual: 40 bits

Integrates 32 double entry TLBs

? High-capacity instruction/data separated cache memories

Instruction: 16 Kbytes

Data: 8 Kbytes

? Memory controller (ROM, EDO-type DRAM, synchronous DRAM (SDRAM), synchronous ROM (SROM), and flash memory supported)

? Keyboard interface and touch panel interface

? 4-channel DMA controller

? Serial interface (NS16550 compatible)

? IrDA interface for infrared communication

? Software modem interface

? A/D and D/A converters to support digital voice I/O

? Supports ISA bus subset

? Power supply voltage: VDD2 = 2.5 V (internal), VDD3 = 3.3 V (external) (131 MHz model)

? Package: 224-pin fine-pitch FBGA

APPLICATIONS

? Battery-driven portable information systems

? Embedded controllers, etc.
