R80251XC - Ultra fast, configurable 32-bit 8051 IP core microcontroller Description:
The R80251XC is a fast, configurable, single-chip internally 32-bit microcontroller IP core compatible to the MCS® 251 and MCS® 51 instruction set.
This highly efficient design runs an average of 3.18 times faster than the 80C251 at the same clock frequency. The Dhrystone benchmark score varies from 0.098 to 0.23 DMIPS/MHz, depending on working mode, which translates to speed improvement of 24.5 over the standard 80C51 and of 2.22 over the 80C251 at the same frequency.
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 interrupts, interfaces for serial communication (UART, I2C and SPI), timers, I/O ports, power management unit, watchdog timer and real-time clock. Integrated on-chip debugging using the native OCDS and the EASE-8051 debugging system is also available.
