The Texas Instruments SMJ44C256-80FQMT is a 1-Mbit Fast Page Mode DRAM with a memory organization of 256K x 4 bits. This component offers an access time of 80 ns and operates in asynchronous mode. It supports CAS BEFORE RAS REFRESH for efficient refresh operations. The SMJ44C256 series is designed for high-reliability applications, operating across a temperature range of -55°C to +125°C. The device is housed in a 20-terminal ceramic, metal-sealed cofired small outline package (CDSO20, R-CDSO-N20) suitable for surface mounting. Its robust construction and specified performance characteristics make it suitable for demanding industrial, defense, and aerospace systems requiring high-speed memory solutions. The supply voltage range is 4.5V to 5.5V with a nominal 5V operation.
