Applications
1:Consumer Electronics: Storing configuration parameters in smart TVs, set-top boxes, and printers.
2:Industrial Control: Data logging and storage of calibration values in industrial PLCs and sensor modules.
3:Communications Equipment: Storing MAC addresses and configuration information in routers and switches.
4:Automotive Electronics: Non-volatile data storage in body control modules and instrument clusters (vehicle-grade qualification needs verification).
5:IoT Devices: Low-power, small-form-factor applications like wearable devices and sensor nodes.
Description
1:High-Density Storage: Offers 256Kbit (equivalent to 32K bytes) of memory capacity, sufficient for the data storage needs of complex applications.
2:I²C Serial Interface: Utilizes a two-wire I²C interface, greatly simplifying connections to microcontrollers (MCUs), saving PCB space and system I/O resources. Supports clock frequencies up to 1MHz for high-speed data transfer.
3:Wide Voltage Operation: Operates from a low voltage of 1.7V up to 5.5V, making it perfectly compatible with a wide range of applications, from portable lithium-battery-powered devices to standard 3.3V and 5V systems.
4:High Reliability & Longevity: Features exceptional endurance of over 1 million write cycles and outstanding data retention of up to 100 years, ensuring the security and stability of critical data.
5:Page Write Mode & Hardware Write Protection: Includes a 64-byte page write buffer, allowing up to 64 bytes to be written in a single operation for improved efficiency. Also provides a dedicated Write Protect (WP) pin for hardware-level prevention of accidental writes, enhancing data security.
6:Industrial Grade: Supports an extended industrial temperature range of -40°C to +85°C, suitable for demanding environmental conditions.
7:ECO-Friendly Package: Housed in a compact, 8-pin SOIC package that complies with environmental standards like RoHS, facilitating automated manufacturing.
