AT27C020-55PU Description

Short technical summary and product information.

The Microchip Technology AT27C020-55PU is a high-performance, low-power 2,097,152-bit EPROM organized as 256K by 8 bits. This OTP EPROM requires a single 5V power supply for normal read operations, with any byte accessible in under 55ns, eliminating the need for wait states in high-speed microprocessor systems.

 

Designed for reliability, the AT27C020 features 2,000V ESD protection and 200mA latchup immunity. It operates within an industrial temperature range of -40°C to 85°C. The device supports a rapid programming algorithm, typically programming in 100µs/byte, and includes an integrated product identification code for use with standard programming equipment.

 

Available in a JEDEC standard 32-lead PDIP package, the AT27C020 is suitable for through-hole mounting. Its CMOS and TTL-compatible inputs and outputs provide design flexibility. The device consumes a typical 8mA in read mode and less than 10µA in standby mode, making it suitable for power-sensitive applications.
