PD39210 is a Microchip-based cost-effective, pre-programmed MCU designed to implement complete PoE control in conjunction with the PD39208 PSE Manager. The PD39210 features a SPI bus to connect up to six PD39208 PSE Managers. It has an embedded ARM Cortex™-M0+ core. The controller uses I2C or UART interface to the host CPU and is designed to support software field upgradable through the communication interface. PD39210 is available in 32 pin, 5 mm x 5 mm QFN package.
