Focusing on the application innovation of connection transmission and real-time performance, the industrial-grade APM32F105/F107 connectivity MCU is based on Arm® Cortex®-M3 cores, operating at 96MHz with powerful and stable computing performance. With built-in 256KB Flash and 64KB SRAM, it supports U(S)RAT, SPI, I2S, I2C, and other communication peripherals, providing a dual CAN bus and USB OTG_FS interface. Meanwhile, the F107 series provides an Ethernet MAC controller, which is compatible with the IEEE-802.3-2002 protocol. By using MII or RMII for Ethernet LAN communication, this series can provide excellent communication interconnection for user products.
