The Texas Instruments SMJ44400-12JDBM is a 4,194,304-bit Fast Page Mode DRAM, organized as 1M x 4 bits. This component features a maximum access time of 120ns and operates using CMOS technology. It supports CAS BEFORE RAS/HIDDEN REFRESH functionality, enabling efficient refresh cycles. The device utilizes a common I/O type and provides 3-state output characteristics. Housed in a 20-pin CDIP package (R-CDIP-T20), it is designed for through-hole mounting with a terminal pitch of 2.54mm. Operating across a wide temperature range of -55°C to +125°C, it requires a supply voltage between 4.5V and 5.5V. The SMJ44400 series, including this part, is often found in high-reliability applications within the aerospace and defense sectors.
