Recently, Geehy officially announced the new industrial-grade APM32F107/F105 series connectivity MCUs based on Arm® Cortex®-M3 core.
Expand communication peripherals and focus on connection function upgrades
The newly added product resources of APM32F107/F105 series MCU have three typical peripherals: USB OTG, Ethernet unit, and dual CAN bus.
Supports configurable Host/Device to enhance communication speed for typical applications such as building control, audio multimedia, and car navigators.
As a cost-effective MCU with a built-in Ethernet MAC controller, APM32F107 is compatible with IEEE-802.3-2002 protocol and uses MII or RMII for Ethernet LAN communication, which can provide excellent internet communication for user products and is suitable for IoT, PLC, measurement instrumentation, communication equipment, and other market segments.
Dual CAN Bus
This series integrates two independent CAN buses to avoid interference introduced by bus outreach and perfect error detection mechanism. High operating frequency and code execution efficiency allow the system to send and receive CAN bus data while still performing bus redundancy algorithms, suitable for the automotive aftermarket.
The APM32F107/F105 series has high-efficiency Flash erase performance under full temperature and voltage environments. Operating in full-speed mode (72MHz, 25℃, 3.6V), the power consumption is 26.17mA and sleep power consumption is 9.42mA, which can ensure the best power consumption ratio while achieving high performance. Moreover, the built-in temperature sensor module has better conversion accuracy than the peer competitors.
Equipped with rich peripherals, the I2C interface (1Mbit/s) supports SMBus/PMBus, and the maximum transmission speed of SPI is 18Mbps, which can meet high-bandwidth application scenarios with a higher data transmission rate. The factory-calibrated 8MHz RC oscillator enables crystal-less design, providing three PLLs with configurable phase-locked loops. The built-in two 12-bit high-speed ADCs (16 external channels) and two 12-bit DACs (dual channels) support the accurate collection of high-efficiency dynamic data.
