Microchip Technology's AT27256-15DM1 is a high-performance CMOS UV Erasable Programmable Read-Only Memory (UVPROM). This component offers a memory density of 262,144 bits, organized as 32K words by 8 bits, with an access time of 150ns. Designed for robust operation, it features a wide operating temperature range from -55°C to +125°C. The AT27256 series utilizes a parallel interface and comes in a 28-lead Ceramic Dual In-line Package (CDIP) with a window for UV erasure, suitable for through-hole mounting. Its typical application environments include industrial control systems, legacy equipment, and specialized data storage where reliable, non-volatile storage is critical. The device operates from a 5V supply voltage.
