Product overview
Overview
DETAILED
The DS80C320/DS80C323 are fast 80C31/80C32-compatible microcontrollers. Wasted clock and memory cycles have been removed using a redesigned processor core. As a result, every 8051 instruction is executed between 1.5 and 3 times faster than the original for the same crystal speed. Typical applications see a speed improvement of 2.5 times using the same code and same crystal.
The DS80C320 offers a maximum crystal rate of 33MHz, resulting in apparent execution speeds of 82.5MHz (approximately 2.5X).
FEATURES
• 80C32-Compatible 8051 Pin and Instruction Set Compatible Four 8-Bit I/O Ports Three 16-Bit Timer/Counters 256 Bytes Scratchpad RAM Addresses 64kB ROM and 64kB RAM
• High-Speed Architecture 4 Clocks/Machine Cycle (8032 = 12) DC to 33MHz (DS80C320) DC to 18MHz (DS80C323) Single-Cycle Instruction in 121ns Uses Less Power for Equivalent Work Dual Data Pointer Optional Variable Length MOVX to AccessFast/Slow RAM/Peripherals
• High-Integration Controller Includes: Power-Fail Reset Programmable Watchdog Timer Early Warning Power-Fail Interrupt
• Two Full-Duplex Hardware Serial Ports
• 13 Total Interrupt Sources with Six External
• Available in 40-Pin DIP, 44-Pin PLCC, and 44-Pin TQFP
