Analog Devices Inc. MAX17841B Auto SPI Communication Interface (ASCI)
Analog Devices Inc. MAX17841B Automotive SPI Communication Interface (ASCI) combines an SPI port with a universal asynchronous receiver transmitter (UART) designed to interface with ADI battery management devices. The UART can be configured to automatically implement Manchester encoding / decoding, message framing, parity, wake-up, and keep-alive signaling as required for Analog Devices’ battery management UART protocol. The UART features programmable baud rates of 0.5Mbps, 1Mbps, or 2Mbps and supports single-ended or differential signaling. The UART contains a 28-byte transmit buffer and a 62-byte receive buffer with host-configurable interrupt events for host efficiency.Features
