Microchip Technology's MAR8251FB is a CMOS Serial I/O Controller from the MAR8251 series, featuring two serial I/O channels. This component operates with a maximum clock frequency of 5.0000 MHz and supports both asynchronous and synchronous communication standards, including ASYNC, BIT, and SYNC, BYTE protocols. Data encoding and decoding are handled via NRZ methods, with a maximum data transfer rate of 0.0078125 Mbps. It utilizes an 8-bit external data bus and is housed in a 68-terminal CQFP (Ceramic Quad Flat Pack) package, specifically identified by JESD-30 code S-CQFP-F68. The package body material is ceramic with a metal-sealed cofired construction, offering a square shape and flat terminals with a 1.270 mm pitch. This device operates within a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5.0V. Environmental specifications include an extended operating temperature range from -55°C to +125°C. The MAR8251FB is designed for surface mounting and adheres to stringent screening level references such as 38535Q/M, 38534H, and 883B. Its capabilities make it suitable for applications in aerospace, defense, and high-reliability industrial systems.
