MOS INTEGRATED CIRCUIT µµµµPD30121 VR4121 TM 64-/32-BIT MICROPROCESSOR Document No. U14691EJ1V0DS00 (1st edition) Date Published June 2000 N CP(K) Printed in Japan DATA SHEET 2000 © 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 MIPS TM RISC architecture. The VR4121 uses the high-performance, super power-saving VR4120 TM 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. Detailed function descriptions are provided in the following user’s manual. Be sure to read it before designing. • VR4121 User’s Manual (U13569E) FEATURES • Employs 64-bit MIPS architecture • Conforms to MIPS III instruction set (deleting FPU, LL, LLD, SC, and SCD instructions) • Memory controller (ROM, EDO-type DRAM, synchronous DRAM (SDRAM), synchronous ROM (SROM), and flash memory supported) • Optimized 6-stage pipeline • Keyboard interface and touch panel interface • Supports MIPS16 instruction set • 4-channel DMA controller • Supports high-speed product-sum operation instructions • Serial interface (NS16550 compatible) • IrDA interface for infrared communication • Supports four types of operating modes, enabling more effective power-consumption management • Software modem interface • A/D and D/A converters to support digital voice I/O • Supports ISA bus subset • Internal maximum operating frequency: 131/168 MHz • On-chip clock generator • Address space physical: 32 bits virtual: 40 bits Integrates 32 double entry TLBs • Power supply voltage: VDD2 = 2.5 V (internal), VDD3 = 3.3 V (external) (131 MHz model) • Package: 224-pin fine-pitch FBGA • High-capacity instruction/data separated cache memories Instruction: 16 Kbytes Data: 8 Kbytes APPLICATIONS • Battery-driven portable information systems • Embedded controllers, etc. ORDERING INFORMATION Part Number Package Internal Maximum Operating Frequency µPD30121F1-131-GA1 224-pin plastic FBGA (16 × 16) 131 MHz µPD30121F1-168-GA1 224-pin plastic FBGA (16 × 16) 168 MHz |
