Overview

The T8051XC3 core implements one of the smallest-available 8-bit MCS®51-compatible microcontrollers. The core integrates a 8051 CPU with a serial communication controller,flexible timer/counter, multi-purpose I/O port,interrupt controller, and optionally with a debug unit supporting JTAG and Single-Wire interfaces. The MCU with all peripherals uses as little as 6.6K gates in an ASIC implementation.. 

The MCU executes some 8051 instructions in a single clock cycle, thus providing 0.1236 DMIPS/MHz (Dhrystone 2.1 benchmark score). Furthermore, the core can run at frequencies over 450 MHz on a 90nm technology, offering performance that is more than 300x that of the original 8051. 

The T8051XC3 runs the legacy code of existing systems, but is also ready for highly productive new software development. This is facilitated through the on-chip debugging option, and debug pods that cooperate with the Keil μVision C51 and IAR Embedded Workbench for 8051 IDEs. 

The T8051XC3 builds on the core design engineering team’s rich experience on the proven 8051 family of processor cores, which have been successfully implemented in hundreds of different customer products since 1997. It is royalty-free,and fully verified , it can be purchased with synthesizable RTL source code or Netlist
