Description

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.
