Ultra-Small 8051-Compatible Microcontroller

The T8051XC3 core implements one of the smallest-available 8-bit MCS®51-compatible microcontrollers. The core integrates an 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 executes some 8051 instructions in a single clock cycle, thus providing 0.1236 DMIPS/MHz or 13.15x the performance per MHz of the original IntelTM 8051. 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 CAST’s on-chip debugging option, and debug pods that cooperate with the Keil μVision C51 and IAR Embedded Workbench for 8051 IDEs.

This T8051XC1 IP core builds on CAST’s experience with hundreds of 8051 IP customers going back to 1997. It is rigorously verified, scan-ready, and available in source-code RTL or targeted FPGA netlist.
