Microchip Technology offers the 27C256-90-SO, a 262144-bit CMOS EPROM organized as 32K words by 8 bits. This asynchronous memory device features a maximum access time of 90ns and operates from a 4.5V to 5.5V supply. The 27C256-90-SO is housed in a 28-lead Small Outline Plastic (PDSO) package with a 1.27mm terminal pitch, suitable for surface mounting. Its CMOS technology ensures low standby current, specifically 2mA maximum. This component provides exceptional data retention exceeding 200 years, making it ideal for applications requiring long-term non-volatile storage. Industries including industrial control, consumer electronics, and communication systems frequently utilize this type of memory for firmware storage and data logging. The device supports parallel data transfer with 3-state outputs.
