The Texas Instruments SMJ4C1024-80HJ is a 1M x 1 Fast Page DRAM featuring 80ns maximum access time and CMOS technology. This component supports RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH modes, with 512 refresh cycles. It operates asynchronously with a supply voltage range of 4.5V to 5.5V, nominal 5V. The SMJ4C1024 series device is housed in a 20-lead CDSOJ (R-CDSO-J20) ceramic, metal-sealed cofired package, suitable for surface mounting with a 1.27mm terminal pitch. Its wide operating temperature range of -55°C to +125°C makes it suitable for demanding applications in aerospace, defense, and industrial control systems requiring high reliability. The 3-state output characteristics ensure efficient bus utilization.
