The TXE81XXEVM allows the evaluation of the TXE81XX family of SPI I/O expanders. This EVM supports TXE8116, TXE8124, and TXE8148 (16-bit, 24-bit, and 48-bit, respectively) in the leaded package type DGS(24 and 32) and DGG (56). The EVM provides access to many test points and headers to accompany the extensive amount of I/O's provided by each expander. There are a mix of male and female header types which allow for easy shunt connections.
