ATMEL AT27C512R-45PU OTP EPROM 512Kbit (64Kx8) 28-Pin DIP

The ATMEL AT27C512R-45PU is a high-performance, 512 Kbit (64K x 8-bit) One-Time Programmable Read-Only Memory (OTP EPROM) in a 28-pin Dual In-line Package (DIP). Engineered using Atmel's scaled CMOS technology, it delivers fast access times, low power consumption, and enhanced reliability, making it an excellent choice for demanding embedded systems.

This device operates from a single 5V power supply and features a rapid 45ns read access time, allowing any byte to be accessed without the need for wait states in high-performance microprocessor applications. This ensures smooth, uninterrupted data flow, which is crucial for real-time operations. The CMOS design not only provides high speed but also contributes to significantly lower active power consumption compared to older technologies.

A standout feature is the rapid programming algorithm, which programmes the device at 100 microseconds per byte, drastically reducing production programming time while guaranteeing data integrity. The integrated product identification code further aids in inventory and system configuration management. The device is designed for high reliability, with an operating temperature range from -40°C to 85°C, suitable for industrial and extended commercial environments.
