1.2 Description

This reference design features the TPS23882/TPS23882B daughtercard, the octal channel, the TPS23882/TPS23882B device, and the IEEE802.3bt ready PoE PSE controller. When paired with the PSE motherboard PSEMTHR24-081 (sold separately) and MCU daughtercard PSEMCUDAUEVM-082/PSEM0MCUDAUEVM-018 (sold separately), users can evaluate the TPS23882/TPS23882B 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)
  • PSEM0MCUDAUEVM-018: MSPM0 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)
  • TPS23882B1EVM-035: TPS23882B 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)
  • XDS110 Debugger: Used with UniFlash GUI for programming the MSPM0
  • 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 is programmed with pre-production firmware for EVM testing purposes. Follow the instructions in this user's guide to flash the latest firmware from the TIDA-050026-23882 folder or the PSEMCUDAUEVM-082 tool folder before evaluation. Similarly, latest firmware for the MSPM0G1107 on PSEM0MCUDAUEVM-018 can be found from the TIDA-050026-23882 folder.
