Microsemi’s™ PoE controller, PD69100, is a cost-

effective, pre-programmed unit designed to implement

Enhanced mode. It is used in conjunction with Microsemi’s

PoE Managers PD69108 and PD69104 in Ethernet

switches to enable next generation network devices to

share power and data over the same cable, as specified in

IEEE802.3af and IEEE802.3at standards. Enhanced

mode operation along with PD69108/PD69104 managers

enables operation in a total Power-over-Ethernet stand-

alone mode.

The controller features an ESPI bus for each PoE device

and a communication interface with Host CPU via UART

or I

2C protocol.

Device is based on STMicroelectronics family

STM32F101T6 embedded with ARM Cortex™-M3 core. It

includes the following peripherals:

 3 x Timers

 2 x Uarts

 1 x SPI

 1 x I

2C

 1 x 12-bit analog-to-digital converter
