XR20M1280L32-0B-EB, Evaluation Kit based on the XR20M1280IL32 UART

XR20M1280L32-0B-EB, Evaluation Kit based on XR20M1280IL32, is a single-channel I2C/SPI Universal Asynchronous Receiver and Transmitter (UART) with integrated level shifters and 128 bytes of transmit and receive FIFOs. for flexibility in a mixed voltage environment, the M1280 has 4 VCC pins. There is a VCC pin for the core, a VCC pin for the UART signals, a VCC pin for the CPU interface signals and a VCC pin for the GPIO signals. The VCC pins for the UART, GPIO and I2C/SPI interface signals allow for the M1280 to interface with devices operating at different voltage levels eliminating the need for external voltage level shifters
