Tiny 8051 IP core comes complete with peripherals
The DT8051 is an area optimized tiny soft core of a single chip 8-bit embedded microcontroller, based on the most popular 8051 MCU. The DT8051 can run in very small FPGA devices or can be just a tiny fragment of a System-on-Chip ASIC. A very low gate count area allows as well to run the core at high performance, up to 300 MHz in Hynix 0.18 library (equivalent performance to the original 80C51, clocked with 2400 MHz). The DT8051 soft core is 100% binary-compatible with the industry standard 8051 8-bit microcontroller, but in comparison to its ancestor, DCD’s IP Core has a very low gate count architecture, giving 6 650 ASIC gates for the complete system with peripherals and the DoCD on-chip debugger.
The DT8051 includes a 2-wire DoCD on-chip debugger (TTAG), up to eight external interrupt sources, an advanced Power Management Unit, Timers 0&1, I/O bit addressable Ports, full duplex UART and interface for external SFR. Furthermore, DCD’s IP Core has a built-in support for the 2-wire TTAG interface – DCD Hardware Debug System, popular DoCD. This version of the debugger is dedicated for applications, where a number of external pins is limited. The DT8051 is delivered with fully automated test bench and complete set of tests, allowing easy package validation, at each stage of SoC design flow.
