Texas Instruments TXE81xxEVM Evaluation Module
Texas Instruments TXE81xxEVM Evaluation Module is engineered for the evaluation of the TXE81xx family of SPI I/O expanders. The TXE81xx family includes 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 TI TXE81xxEVM Evaluation Module provides access to numerous test points and headers, complementing the extensive amount of I/Os offered by each expander. There is a mix of male and female header types that enable easy shunt connections.
Features
- USB powered (5V and 3.3V options)
- Option for external power
- ICC current measurement header (for current consumption measurements)
- Various male and female connection headers + test points for quick testing
- On-board USB2ANY for minimal SPI driver setup
- On-board USB2ANY works with an online GUI in the cloud or downloads to the desktop
- LEDs for visual feedback (port/RESET/INT)
- LED enable/disable header
- Additional test points and headers for SPI connections (SDI/SDO/SCLK/CS)
- Can be used with external drivers such as MSPM0, TP Aardvark, TP Cheetah, TP Promira, Arduino, and ESP32
- Manual reset toggle switch to reset the SPI to the I/O expander
- Daisy chain capable between multiple TXE81XXEVMs
Applications
- Extending the GPIOs of an MCU
- Sensor control
- Driving LEDs and arrays
- Keypad/matrix handling
