MCU M4 AT32F403ARCT7 PIN To PIN Alternative M3 STM32F411RCT6 STMF105RCT6 STM32F103RCT6 STM32F103RBT6
MCU M4 AT32F403ARCT7 PIN To PIN Alternative M3 STM32F411RCT6 STMF105RCT6 STM32F103RCT6 STM32F103RBT6 Software hardware is completely compatible
1. High compatibility: compatible with Sxx32F103 pins & highly compatible with software
2.M4 main frequency 240MHz (with FPU/DSP), RAM up to 224KB
3.AT32F403ARC/VC can replace the Sxx103RE/VE project just because of insufficient RAM
4. Rich peripherals: I2Cx3, SDIO x 2, SPI/I2S (full duplex) x 4, CANx2, UARTx8, 32-bit Timer, SPIM can be connected to high-speed SPI NOR Flash
5. Built-in sLib function: unique security & secondary development function
6. High computing power, one can replace multiple
7. Support wide operating temperature range (-40-105 degrees)
