AT27C512R-70PU Description

Short technical summary and product information.

The Atmel AT27C512R-70PU is a high-performance, low-power 512Kbit One-Time Programmable (OTP) EPROM. It is organized as 64K words by 8 bits, requiring a single 5V power supply for normal read operations. With a maximum access time of 70ns, it eliminates the need for wait states in high-performance microprocessor systems.

 

This device utilizes Atmel's scaled CMOS technology for high speed and low power consumption. It typically draws 8mA in active mode and less than 10µA in standby mode. The AT27C512R-70PU operates within an industrial temperature range of -40°C to 85°C.

 

Available in a JEDEC-standard 28-lead PDIP package, it is designed for through-hole mounting. The device features two-line control (CE, OE) for flexibility in preventing bus contention. It also includes features like 2,000V ESD protection and 200mA latchup immunity, ensuring high reliability.
