## Hardware

Platform Intel MCS-51 (8051): The Intel MCS-51 (commonly termed 8051) is an internally Harvard architecture, complex instruction set computer (CISC) instruction set, single chip microcontroller (uC) series developed by Intel in 1980 for use in embedded systems.

Microcontroller | STC15F204EA
Frequency | 11MHz
Flash | 4KB
RAM | 256B
Vendor | STC

## Configuration

Please use `stc15f204ea` ID for board option in “platformio.ini” (Project Configuration File):

    [env:stc15f204ea]
    platform = intel_mcs51
    board = stc15f204ea

You can override default Generic STC15F204EA settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest stc15f204ea.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:stc15f204ea]
    platform = intel_mcs51
    board = stc15f204ea

    ; change microcontroller
    board_build.mcu = stc15f204ea

    ; change MCU frequency
    board_build.f_cpu = 11059200L

## Debugging

PIO Unified Debugger currently does not support Generic STC15F204EA board.
