Texas Instruments SMJ55161-70HKCM is a 4Mbit CMOS Video DRAM with a memory organization of 256K words by 16 bits. This component offers a maximum access time of 70ns and supports Fast Page Mode with EDO capabilities. It features dual ports with a SAM port for 256x16 access and supports various refresh modes including RAS Only, CAS Before RAS, and Hidden Refresh cycles. Designed for operation across an extended temperature range from -55°C to +125°C, it is housed in a 64-terminal ceramic, metal-sealed cofired flatpack (CDFP64, R-CDFP-F64). This device finds application in high-reliability systems for graphics processing and video display technologies. The SMJ55161-70HKCM operates with a supply voltage range of 4.5V to 5.5V.
