Microchip Technology's 27C256-90I-L is a 32K x 8 (262,144 bit) Electrically Programmable Read-Only Memory (EPROM). This CMOS device features a maximum access time of 90ns and operates from a 4.5V to 5.5V supply. The memory organization is 32,768 words by 8 bits, with common I/O and asynchronous operation. Designed for reliable data retention exceeding 200 years, it is housed in a 32-lead PQCC (JESD-30 Code R-PQCC-J32) package. Typical applications span industrial control, telecommunications infrastructure, and legacy system upgrades where robust non-volatile storage is critical. The component offers 3-state outputs and a programming voltage of 13V. Operating temperature range is -40°C to +85°C.
