PD69100

WWW.Microsemi .COM ® TM DESCRIPTION Microsemi’s™ PoE controller, PD69100, is a costeffective, 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 standalone mode. The controller features an ESPI bus for each PoE device and a communication interface with Host CPU via UART or I2C 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 I2C  1 x 12-bit analog-to-digital converter PIN CONFIGURATION VDD2 VSS2 SWDIO xLED_OE xLED_Latch I2C_Message_Ready xInt_Out xLED_CS VDD1 27 26 25 24 23 22 21 20 19 SWCLK 28 xDisable_Ports 29 xHswp_On 30 Spare 31 xSys_OK 32 SCL / UART1_TX 33 SDA / UART1_RX 34 Boot0 35 VSS3 36 < -Software Ver > < Date Code > 12 3 4 5 6 7 8 9 18 VSS1 17 Reserved 16 I2C_ADDR 15 HW_VER 14 ESPI_MOSI 13 ESPI_MISO 12 ESPI_SCK 11 ESPI_xCS 10 Reserved PD69100 PoE Controller Unit DATASHEET KEY FEATURES  Controls up to 48 PoE ports (6 x PD69108)  Pre-Standard / Capacitor detection  Detection of Cisco devices  Supports both UART and I2C interfaces to Host CPU  Backwards compatib...
