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

Microchip AT28C256-15JU is a 256 kB Parallel EEPROM memory device with a fast 150 ns access time enclosed in a 32-Pin PLCC package, supporting Serial-2 Wire interface for parallel data communication. This electrically erasable programmable read-only memory offers individual byte-level addressing and is suitable for applications demanding non-volatile storage with reliable data retention up to 10 years.

Operating within a voltage range of 4.5V to 5.5V, the device supports a maximum clock frequency of 5 MHz and a maximum random access time of 150 ns. It features a 32K x 8 bit organization with 8 bits per word, and a supply current of 50 mA, making it efficient for embedded systems and industrial electronics.

The PLCC package with 32 pins is designed for through-hole mounting, with compact dimensions including a length of 14.1 mm, width of 11.51 mm, and height of 2.8 mm. The EEPROM operates reliably in harsh environments over a temperature range of -40°C to 85°C.

This product is ideal for program storage where data changes are infrequent, such as industrial control, automotive electronics, and consumer devices requiring non-volatile memory. It provides robustness against frequent power cycles while retaining the written data securely.
