1.2 Description

This reference design features the TPS23882 daughtercard, the octal channel, the TPS23882 device, and the IEEE802.3bt ready PoE PSE controller. When paired with the PSE motherboard PSEMTHR24-081 (sold separately) and MCU daughtercard PSEMCUDAUEVM-082 (sold separately), users can evaluate the TPS23882 device and PSE system firmware solution.

The full PoE evaluation ecosystem includes the following:

  • PSEMTHR24EVM-081: motherboard for 24-port PoE PSE applications (sold separately)
  • PSEMCUDAUEVM-082: MSP430 daughtercard for 24-port PoE PSE applications (sold separately)
  • TPS23882EVM-084: TPS23882 daughtercard for 24 port Type 3 (2 pair) PSE PoE PSE applications (sold separately)
  • USB2ANY interface adapter: used with PSE system firmware GUI for I2C/UART interaction with the PSEMCUDAU-082 daughtercard (sold separately)
  • MSP-FET programmer: used with Uniflash GUI for programming the MSP430 device
  • PSE system firmware code image (request access to the code image through TIDA-050026-23882 folder or PSEMCUDAUEVM-082 tool folder)
  • PSE system firmware GUI (request access to the code image through TIDA-050026-23882 folder or PSEMCUDAUEVM-082 tool folder)

    • NOTE

    The MSP430F5234 on PSEMCUDAUEVM-082 has been programmed with pre-production firmware for EVM testing purposes. Please follow the instructions in this user's guide to flash the latest firmware from TIDA-050026-23882 folder or PSEMCUDAUEVM-082 tool folder before evaluation.
