PD69210 PoE Controllers Microchip Technology PD69210 PoE Controllers are cost-effective, pre-programmed MCUs. These controllers are designed to implement Enhanced mode PoE control in conjunction with the PD69208M, PD69208T4, and PD69204T4 PSE managers. The PD69210 controllers feature an embedded ARM Cortex™-M0+ core. These controllers utilize the I2C or UART interface to the host CPU and are designed to support software field upgradable through the communication interface. The PD69210 controllers are available in a 32-pin 5mm × 5mm QFN package.
