Overview

INTEGRATED CIRCUITS PR31700 32-bit RISC microprocessor Preliminary specification Supersedes data of 1997 Dec 15 1998 May 13 Philips Semiconductors Philips Semiconductors Preliminary specification 32-bit RISC microprocessor PR31700 GENERAL DESCRIPTION The PR31700 is a single-chip digital ASSP (Application Specific Stand Product) used in HPCs (Handheld Personal Computers), Palm-size PCs, Screenphones, Smartphones, and other vertical market applications in the mobile computing and communication markets.
The PR31700 consists of system support logic, integrated with the PR3901 Processor Core designed by Philips Semiconductors.
• Built-in peripheral circuit – Clock generator with built-in eightfold-frequency phase-locked loop (PLL) – Four-stage write buffer – A high performance and flexible Bus Interface Unit – Multiple DMA channels – Memory controller for DRAM, HDRAM, SDRAM, SRAM, ROM, Flash Memory and PCMCIA – Power management unit – Big / Little endian FEATURES • R3000A-based PR3901 Processor Core – RISC architecture developed by MIPS Technologies, Inc.
– Philips has added its own multiply-add and branch-likely instructions.
– A single-cycle multiply/accumulate module to allow integrated DSP functions, such as a software modem for high-performance standard data and fax protocols – Instruction cache: 4K bytes; data cache: 1K bytes – On-chip Translation Lookaside Buffer (TLB) with 3264-bit wide entries, each of which maps 4KByte page Max 75MHz operation • Low power dissipation – 3.
3V operation – Standby Current 10A(typ) – CPU clock stop mode – Power down modes for individual internal peripheral modules • Plastic LQFP 208-pin package The information contained herein is subject to change without notice.
Philips is continually working to improve the quality and the reliability of its products.
Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress.
It is the respon...
