HN58C256AFP-10 256K Electrically Erasable and Programmable ROM SMD (SOP-28)

The HN58C256AFP-10 is a high-performance 256k-bit EEPROM (Electrically Erasable and Programmable Read-Only Memory) designed for non-volatile data storage. Fabricated using advanced CMOS technology, it provides high-speed operation with extremely low power dissipation, making it suitable for modern embedded systems. The device supports a page write mode, allowing up to 64 bytes of data to be written in a single internal programming cycle, which significantly reduces the total programming time. It also includes a Data Polling feature and a Toggle Bit function to allow microprocessors to detect the completion of a write cycle without external hardware. Housed in a compact 28-pin SOP surface-mount package, this IC is widely used for storing firmware, calibration data, and configuration parameters in telecommunications, automotive electronics, and industrial control systems.

Key Features:

Fast access time of 100 nanoseconds for high-speed data retrieval.

Low power consumption with a maximum active current of 15 milliamps.

Features an automated page write cycle of 64 bytes for efficient data updates.

Built-in data protection mechanism to prevent accidental writes during power transitions.

High reliability with an endurance of 10,000 write cycles and 10-year data retention.
