The Texas Instruments SMJ44C251-10JDM is a 1Mbit (256K x 4) Video DRAM operating at 100ns access time. This component features CMOS technology for low power consumption, with a standby current of 15mA and a maximum operating supply current of 110mA across a 4.5V to 5.5V supply voltage range. It supports FAST PAGE mode access, along with RAS ONLY, CAS BEFORE RAS, and HIDDEN REFRESH modes, facilitating efficient data transfer. The SMJ44C251 series is designed for applications requiring high-speed video memory, including graphics controllers and display systems. This specific part is housed in a 28-lead Ceramic Dual In-line Package (CDIP) with through-hole termination, operating within a temperature range of -55°C to +125°C. Its rugged construction and wide operating temperature make it suitable for demanding environments.
