Universal Synchronous Asynchronous Receiver Transmitter The MSM82C51A-2 is a USART (Universal Synchronous Asynchronous Receiver Transmitter) for serial data communication. As a peripheral device of a microcomputer system, the MSM82C51A-2 receives parallel data from the CPU and transmits serial data after conversion. This device also receives serial data from the outside and transmits parallel data to the CPU after conversion. The MSM82C51A-2 configures a fully static circuit using silicon gate CMOS technology. Therefore, it operates on extremely low power at 100 mA (max) of standby current by suspending all operations. Features: Wide power supply voltage range from 3 V to 6 V Wide temperature range from -40C to 85C Synchronous communication up to 64 Kbaud Asynchronous communication up to 38.4 Kbaud Transmitting/receiving operations under double buffered configuration. Error detection (parity, overrun and framing)
