Texas Instruments TMS44C256-10NL is a 1,048,576-bit CMOS Fast Page Mode DRAM, organized as 256K words by 4 bits. This component offers an access time of 100ns and operates with a supply voltage range of 4.5V to 5.5V. The TMS44C256 series supports various refresh modes, including RAS-only, CAS-before-RAS, and hidden refresh, with 512 refresh cycles required. Its 20-pin PDIP (Plastic Dual In-line Package) with through-hole mounting is suitable for applications in computing, telecommunications, and industrial control systems where reliable memory is critical. The 3-state output characteristics enable efficient bus utilization.
