MOS INTEGRATED CIRCUIT µµµµPD30181A, 30181AY VR4181A TM 64-/32-BIT MICROPROCESSOR DATA SHEET © 2002 © 1997 The mark shows major revised points. Document No. U16277EJ1V0DS00 (1st edition) Date Published October 2002 N CP(K) Printed in Japan DESCRIPTION The µPD30181A and 30181AY (VR4181A), which are high-performance 64-/32-bit microprocessors employing the RISC (reduced instruction set computer) architecture developed by MIPS TM, are products in the VR SeriesTM of microprocessors manufactured by NEC. The VR4181A includes as its CPU the VR4120™ core, an ultra-low-power-consumption core featuring cache memory, a high-speed product-sum operation unit, and a memory management unit. Other on-chip components include an LCD controller, CompactFlash controller, USB host/function controller, DMA controller, SDRAM controller, PWM controller, AC97/I 2S audio interface, full-duplex asynchronous serial interface, IrDA interface, I2C serial interface, keyboard interface, touch panel interface, real-time clock, A/D converter, D/A converter, and other controllers and interfaces required for battery-driven mobile information devices, fixed compact information devices, car navigation systems, and compact embedded devices. Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before designing. •••• VR4181A Hardware User’s Manual (U16049E) •••• VR4100 SeriesTM Architecture User’s Manual (U15509E) FEATURES VR4120 core (64-bit RISC core) on chip as CPU Pipeline clock: 131 MHz Conforms to MIPS III (except for FPU, LL and SC instructions) and MIPS16 instruction sets Supports MACC and DMACC high-speed product-sum operation instructions On-chip cache memory Capacity includes 8 KB instruction cache and 8 KB data cache Employs a writeback cache Physical addresses: 32 bits Virtual addresses: 40 bits On-chip 32 double-entry TLB Effective power management using four modes: Fullspeed, Standby, Suspend, and Hibernate Employs a high-performance internal system bus (T- bus) DRAM controller supporting 64 Mb, 128 Mb, and 256 Mb SDRAMs External system bus interface supporting ROM, page ROM, flash memory, SRAM, ISA devices, IDE (ATA) devices, and SyncFlash™ memory UMA type LCD controller (supports STN and TFT panels) ExCA register-compatible CompactFlash interface (2 slots) USB host controller (Rev1.1, OHCI Rev1.0) controller USB function (Rev1.1) controller AC97 and I 2S audio interfaces (1 channel each) Clocked serial interface (1 channel) NS16550-compatible serial interface (3 channels) IrDA (SIR) interface (1 channel) I 2C bus interfaces (2 channels, µPD30181AY only) PWM controller (3 channels) DMA controller supporting chain mode (4 channels) Keyboard scan interface (supports 8 × 12 key matrix) X-Y coordinate auto scan touch panel interface On-chip A/D converter and D/A converter On-chip watchdog timer unit RTC unit (total of 3 timer and counter channels) On-chip PLL and clock generators Power supplies: 2.5 V for core, 3.3 V for I/O block Package: 240-pin plastic FBGA |
