AT27C256R-70JU Description

Short technical summary and product information.

The Microchip AT27C256R-70JU is a 256 kilobit EPROM (Erasable Programmable Read-Only Memory) device. It is designed for applications requiring non-volatile data storage and features a fast access time of 70 nanoseconds.

 

This EPROM operates with a supply voltage ranging from 4.5V to 5.5V and has an organization of 32K x 8 bits. The reprogramming technique is OTP (One-Time Programmable), meaning it cannot be erased and reprogrammed after initial programming, as the package lacks a window.

 

Packaged in a 32-pin PLCC (Plastic Leaded Chip Carrier), the AT27C256R-70JU is suitable for through-hole mounting. Its operating temperature range is from -40°C to 85°C, making it robust for various environmental conditions. The device consumes a low supply current of 100μA.

 

This component is ideal for embedded systems and applications where data integrity and reliable storage are crucial. Its parallel interface and standard memory organization facilitate integration into existing designs.
