PY264 8K X 8 REPROGRAMMABLE PROM is a CMOS EPROM with high speed, low power consumption, single 5V±10% power supply, windowed package, and reprogramming capabilities.
The Pyramid PY264 is an 8K x 8 bit CMOS Programmable Read-Only Memory (PROM) utilizing EPROM technology. The device features high-speed operation with access times of 35, 45, or 55 nanoseconds and low power consumption options for both commercial and military applications.
The PY264 is available in two primary package types: a windowed Ceramic DIP (CERDIP) which allows erasure via UV light, and a non-windowed Plastic DIP. It operates with a single +5V supply and is fully TTL compatible, making it suitable for various embedded systems requiring reprogrammable memory storage.
