Product details

The HN58C257AT85E is a parallel-interface 256Kbit EEPROM from the HN58C257 series, organized as 32K x 8 bits. It is designed for nonvolatile storage in applications that need byte-level rewritability without battery backup — think configuration parameters, calibration constants, or firmware patches in industrial controllers, telecom line cards, and metering equipment. The parallel interface gives it a straightforward bus connection to most MCUs and FPGAs, with no SPI or I2C protocol overhead.

Bulk delivery — practical for low-volume or repair

That suits small-batch production runs, prototype builds, or MRO repair where you need a handful of devices rather than a full reel.

Frequently asked questions

What is HN58C257AT85E equivalent to or a replacement for other 256Kbit parallel EEPROMs like AT28C256?

The HN58C257AT85E is a 256Kbit parallel EEPROM in the same functional class as the AT28C256. Both are 32K x 8 devices with a parallel bus interface. Pin compatibility depends on the specific package variant — verify the footprint against your board's socket or solder pattern before substitution.
