The DT8051 is a tiny soft core of a single-chip 8-bit embedded microcontroller, based on the world's fastest and most popular DP8051 core. It is 100% binary-compatible with the industry standard 8051 8-bit microcontrollers, with a very low gate count architecture of 6,650 ASIC gates including the DoCD on-chip debugger. The DT8051 runs Dhrystone 2.1 benchmark program exactly 8.1 times faster than the original 80C51 at the same frequency, using the same C compiler and settings. It includes a 2-wire DoCD on-chip debugger (TTAG™), eight external interrupt sources, an advanced Power Management Unit, full duplex UART, and more. It is suitable for low power battery-operated devices, mixed signal systems, and area optimized FPGA/ASIC designs.
