HN58C256AP-10 Description

Short technical summary and product information.

The HN58C256AP-10 from Hitachi is a 256k bit electrically erasable and programmable read-only memory (EEPROM). It is organized as 32768 words by 8 bits, offering a high-speed, low-power solution for data storage.

This EEPROM utilizes advanced MNOS memory technology and CMOS circuitry for enhanced reliability. Key electrical specifications include a single 5V ±10% supply voltage, a maximum access time of 85 ns, and low power dissipation. Active power consumption is typically 20 mW/MHz, while standby power is a maximum of 110 µW.

The device supports a 64-byte page programming function for faster write operations, with automatic byte and page writes completing in a maximum of 10 ms. It also features on-chip latches for address, data, and control signals (CE, OE, WE), data protection circuits, and conforms to the JEDEC byte-wide standard.

Available in a 28-pin plastic DIP package with 600 mil lead spacing, the HN58C256AP-10 is suitable for industrial applications with operating temperature ranges of -20°C to 85°C or -40°C to 85°C. It offers 10^5 erase/write cycles and 10 years of data retention.
