The MAX17841B ASCI combines an SPI port with a universal asynchronous receiver transmitter (UART) specially designed to interface with Maxim battery management devices.
The UART can be configured to automatically perform Manchester encoding/decoding, message framing, parity, wake-up, and keep-alive signaling as required for Maxim’s battery management UART protocol.
The UART has programmable baud rates of 0.5Mbps, 1Mbps, or 2Mbps and supports either single-ended or differential signaling. For host efficiency, the UART contains a 28-byte transmit buffer and a 62-byte receive buffer with host-configurable interrupt events.
