FEATURES § 80C32-compatible - 8051 pin- and instruction set-compatible - Full duplex serial port - Three 16-bit timer/counters - 256 bytes scratchpad RAM - Multiplexed address/data bus - Addresses 64 kB ROM and 64 kB RAM § High-Speed Architecture - 4 clocks/machine cycle (8051 = 12) - Runs DC to 33 MHz clock rates - Single-cycle instruction in 121 ns - Dual data pointer - Optional variable length MOVX to access fast/slow RAM /peripherals § 10 total interrupt sources with 6 external § Internal power-on reset circuit § Upwardly compatible with the DS80C320 § Available in 40-pin PDIP, 44-pin PLCC, and 44-pin TQFP PACKAGE OUTLINE DESCRIPTION The DS80C310 is a fast 80C31/80C32-compatible microcontroller. It features a redesigned processor core without wasted clock and memory cycles. As a result, it executes every 8051 instruction between 1.5 and 3 times faster than the original architecture for the same crystal speed. Typical applications will see a speed improvement of 2.5 times using the same code and the same crystal. The DS80C310 offers a DS80C310 High-Speed Micro www.maxim-ic.com PRELIMINARY |
