Microchip Technology's 27C512A-90E-SO is a 512 kbit CMOS OTP ROM organized as 64K words by 8 bits. This asynchronous memory device features an access time of 90 ns and operates from a 5V supply. The 27C512 series component is housed in a 28-lead SOIC (Small Outline Integrated Circuit) package, specifically a R-PDSO-G28, with a 1.27mm terminal pitch. Designed for robust performance, it offers data retention exceeding 200 years and operates across a temperature range of -40°C to 125°C. Applications include industrial control, consumer electronics, and legacy system support where reliable, non-volatile data storage is critical. The I/O is common and the output characteristics are 3-state.
