Device Overview

Summary

Single-cycle microcontroller with 64KB ISP flash. It includes 8192 bytes flash data memory, 4352 bytes RAM, PWM, UART, TWI, SPI, up to 38 I/Os, 10-bit A/D, an internal RC oscillator, and on-chip debug.

Key Features:

  • 100% compatible with 80C51 instruction set, with on average 9 times more throughput than standard 12-clock 8051s, up to 1 MIPs per MHz.
  • Hardware acceleration of DSP routines like FIR/IIR filters using the 16x16+40 Multiply-Accumulate Unit and circular buffer addressing.
  • Enhanced PWM modes for advanced waveform generation.
