The Texas Instruments SMJ68CE256-55FGM is a 32K x 8 standard CMOS SRAM with an access time of 55ns. This asynchronous memory component features an automatic power-down function to reduce standby current, which is specified at a maximum of 200µA at 4.5V. The device operates across a wide temperature range from -55°C to +125°C and supports a supply voltage range of 4.5V to 5.5V. It is housed in a 32-terminal ceramic cofired chip carrier (CQCC32) package, suitable for surface mounting applications. The SMJ68CE256 series is utilized in demanding environments, including aerospace and defense systems, where high reliability and robust performance are critical. Its 3-state outputs and output enable functionality facilitate integration into complex bus architectures.
