Texas Instruments MSP430F5234IRGZR | Demoboard TIDA-050026-23881

Description

This reference design showcases a Type-4, 90W, 4-Pair 24-port Ethernet switch for Power over Ethernet (PoE) applications which can send up to 90W per port for IEEE 802.3bt Type 4 applications and up to 120W per port for non-standard applications. Based on the MSP430F523x family, TI's TPS2388x FirmPSE system firmware provides a total system level solution for multi-port applications which reduces time to market and frees-up valuable software resources. This design supports port power management with priority, multiple power supplies, legacy PD detection, field upgradability, UART/I2C communication with the host, and more. TI’s FirmPSE system firmware GUI for this design enables the customization of production level PSE system firmware code with just a few clicks of a button and provides real-time communication to the system. In addition, two of these designs may be cascaded through the edge connectors in order to support up to 48-port PSE systems.
