8-bit ASM51 Compatible Controller
Overview
Core8051s is an ASM51-compatible microcontroller core that can run programs written for the 8051. It contains the main 8051 core logic but no peripheral logic. Core8051s has an APB bus interface that can be used like the SFR bus to easily expand the functionality of the core by connecting it to existing APB IP peripherals. This allows users to configure the core with the peripheral functions (timers, UARTs, I/O ports, etc.) that they need for their application.
