Generic STC89C52RC

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 STC89C52RC
Frequency 11MHz
Flash 8KB
RAM 512B
Vendor STC

Configuration

Please use stc89c52rc ID for board option in “platformio.ini” (Project Configuration File):

[env:stc89c52rc]
platform = intel_mcs51
board = stc89c52rc

You can override default Generic STC89C52RC settings per build environment using board_*** option, where *** is a JSON object path from board manifest stc89c52rc.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:stc89c52rc]
platform = intel_mcs51
board = stc89c52rc

; change microcontroller
board_build.mcu = stc89c52rc

; change MCU frequency
board_build.f_cpu = 11059200L

Debugging
