Microchip Technology MAR8251LB is a CMOS Serial I/O Controller from the MAR8251 series. This component features 2 serial I/O channels and operates with a maximum data transfer rate of 0.0078125MBps. It supports ASYNC and BIT communication standards, along with SYNC and BYTE modes, utilizing NRZ data encoding. The device includes an 8-bit external data bus and is housed in a 48-terminal Ceramic, Metal-Sealed Cofired CQCC48 package (JESD30 Code S-CQCC-N48). Operating within a temperature range of -55°C to +125°C, it requires a supply voltage between 4.5V and 5.5V, with a nominal 5.0V. This surface-mount component is suitable for demanding applications in aerospace, defense, and industrial automation where robust serial communication is critical.
