The X28C256EMB-35 is a 256K EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Xicor Inc. It is organized as 32K x 8 bits and designed for applications requiring non-volatile storage that can be electrically erased and reprogrammed in-system. This EEPROM is ideal for storing configuration data, calibration parameters, and other data that needs to be updated periodically.

Applications

• Data storage in embedded systems
• Configuration memory for programmable logic devices (PLDs)
• Calibration data storage
• Storage of system parameters
• Industrial control systems
• Instrumentation

Features

• Organization: 32K x 8 bits
• Fast Access Time: 350 ns
• Single 5V power supply
• Automatic Page Write Operation: Supports page write for faster programming.
• Self-Timed Write Cycle: Simplifies write operations.
• Data Polling: Allows for monitoring of write cycle completion.
• Endurance: 10,000 Erase/Write Cycles (minimum)
• Data Retention: 10 years (minimum)
• Package: 28-pin DIP and SOIC

Benefits

• In-system programmability: Allows for easy updating of data without removing the device from the system.
• Fast access times: Provides quick data retrieval for improved system performance.
• Simplified write operations: Self-timed write cycle simplifies programming and reduces system overhead.
• High endurance and data retention: Ensures reliable storage of data over a long period.
• Flexible memory management: Page write operation improves programming efficiency.

Additional Details

The X28C256EMB-35 operates from a single 5V power supply and features an automatic page write operation for faster programming. The self-timed write cycle simplifies write operations and reduces system overhead. The device also includes a data polling feature that allows for monitoring of write cycle completion. With a minimum endurance of 10,000 erase/write cycles and a data retention of 10 years, the X28C256EMB-35 provides reliable non-volatile storage for a wide range of applications. The memory is available in 28-pin DIP and SOIC packages.
