ARM Cortex-M3, 32bit, 72 MHz RISC MCU 32-Bit 128KB Flash 2.5V/3.3V, Replaces STM32F103C8T6
Currently ST's STM32 series microcontrollers have over a 1 year long lead times our production stopped for many products in which we used it regularly.
We kept finding an alternate part and finally success with this part APM32F103CBT6
from Geehy. Our goal was to find a equivalent part by which we could just replace it without changing our PCB, Code, Hex, Testing and production. This part is the answer to our quest finally settled. Hope you can start your production again with this STM32 equivalent part.
This APM32F103CBT6 devices works out of box with same ST-Link programmer
as well as same HEX file and source code that is made for STM32F103C8
without changing anything in our setup or production.
