R8051XC2 - Fast and Configurable 8051 MCU

The R8051XC2 is a fast, configurable, single-chip 8-bit microcontroller 8051 IP core that can be used to implement a variety of designs utilizing the MCS® 51 instruction set.

The Dhrystone2.1 benchmark score for the R8051XC2 shows speed improvement from 9.4 to 12.1 over the Intel® 80C51 at the same frequency, or 400 times its maximum performance when implemented in 90 nm process at 430 MHz.

A rich set of optional features and peripherals enables designers to closely match the core with their specific application and hardware requirements (FPGA, ASIC, or structured ASIC). These options include memory pointers, interrupts, interfaces for serial communication (UART, I2C and SPI), timer system, I/O ports, power management unit, multiplication-division unit, watchdog timer, DMA controller and a real-time clock. Integrated on-chip debugging is realized through the proprietary EASE-8051 solution.
