The PB8051 Microcontroller, crafted by Roman-Jones, is an exemplary implementation of the famed 8051 family of microcontrollers. Designed for compatibility with Xilinx FPGAs, it duplicates the 8031 model, which includes key features such as timers and a serial port, providing seamless execution of existing 8051 object code. This core excels by leveraging the Xilinx PicoBaze softcore, prioritizing a compact design while delivering performance comparable to a 12 MHz 8051 at a fraction of the conventional core size.
Optimized for small scale application, the PB8051 takes up only around 300 slices, making it extremely efficient for FPGA utilization. With versatile configurability, it caters to custom 8051 setups and supports varying system configurations. Its compatibility with VHDL and Verilog ensures ease of integration within standard design flows, while also supporting diverse simulation tools like ModelSim.
The microcontroller core is constructed with a robust focus on ease of use, supporting a broad spectrum of applications across different FPGA families, from Spartan II upwards. This makes it a versatile choice for designers seeking a powerful yet flexible microcontroller solution that facilitates agile and adaptive deployment within FPGA environments.
