The Texas Instruments SMJ4C1024-80HJM is a 1M x 1 Fast Page DRAM with an 80ns maximum access time. This CMOS component features separate I/O and supports CAS BEFORE RAS REFRESH functionality with 512 refresh cycles. It operates in a synchronous mode and is packaged in a 20-lead ceramic CDSO (SOJ) package with J-bend terminals, suitable for surface mounting. Designed for industrial and military applications, it operates across a wide temperature range of -55°C to +125°C. The SMJ4C1024 series is utilized in high-reliability systems where robust performance and extended environmental tolerance are critical. This component meets stringent screening level references such as 883B.
