AT27C1024-70PU Description

Short technical summary and product information.

The Microchip Technology AT27C1024-70PU is a high-performance, low-power 1,048,576-bit one-time programmable (OTP) EPROM. It is organized as 64K words by 16 bits, making it suitable for 16- and 32-bit microprocessor systems.

 

This EPROM offers a fast read access time of 70 ns and operates from a single 5V power supply. It consumes low power, with a maximum active current of 30mA at 5MHz and a standby current of 100µA maximum. The device is designed for reliability with 2000V ESD protection and 200mA latchup immunity.

 

The AT27C1024-70PU is available in a 40-lead PDIP package, designed for through-hole mounting. It operates within an industrial temperature range of -40°C to 85°C. The device features CMOS- and TTL-compatible inputs and outputs, along with two-line control (CE, OE) to prevent bus contention in high-speed systems.
