Microchip 256 kB Parallel EEPROM 150 ns 5 MHz 32-Pin PLCC Serial-2 Wire AT28C256-15JU

Microchip AT28C256-15JU is a high-performance 256 kB Parallel EEPROM memory device designed for industrial and electronic applications requiring reliable non-volatile data storage. With a fast 150 ns maximum random access time and a maximum clock frequency of 5 MHz, this Serial-2 Wire interface EEPROM ensures efficient and precise memory operations.

The device is housed in a 32-Pin PLCC package suitable for through-hole mounting, making it compatible with various circuit designs requiring solid memory components. Operating voltage ranges from 4.5 V to 5.5 V, accommodating typical electronic supply conditions with a supply current of 50 mA.

It supports individual byte addressing allowing data write on a per-byte basis, differing from flash memory's block erase. This makes it suitable for applications where frequent reading is needed, but writing cycles are limited. The product offers 10 years of data retention ensuring data safety over long periods.

The operating temperature range from -40°C to 85°C facilitates usage in industrial environments exposed to variable and extreme temperature conditions. The compact physical dimensions - 14.1 mm length, 11.51 mm width, and 2.8 mm height - allow easy integration even in constrained PCB layouts.

Fast 150 ns maximum random access time for efficient data retrieval. Serial-2 Wire interface supports seamless data communication protocols. 10 years guaranteed data retention providing longevity and reliability. Wide operating temperature range from -40°C to 85°C for robust industrial use.

Low power consumption with a supply current of 50 mA at nominal voltages. Compact 32-Pin PLCC package provides durable physical support and easy mounting. Organization of 32K x 8 bit and 32768 words supporting extensive memory use cases.

Non-volatile EEPROM technology for stable and rewritable program storage. This AT28C256-15JU model from Microchip is ideal for electronics and industrial applications involving memory storage for programs and data that require precision and reliability.
