AT24C256W-10SI-1.8

Memory IC Overview

The AT24C256W-10SI-1.8 is a 256Kbit (32K x 8) serial electrically erasable and programmable read-only memory (EEPROM) manufactured by Microchip Technology. It features an I2C-compatible two-wire serial interface with a maximum clock frequency of 100 kHz at the 1.8V supply voltage. The device operates within a supply voltage range of 1.8V to 3.6V and supports industrial temperature ranges from -40°C to +85°C. It is housed in an 8-lead JEDEC SOIC package.

Memory IC Feature Summary

• Supports bidirectional data transfer via a two-wire serial interface compatible with standard I2C protocols.
• Includes a hardware write protect pin that inhibits all write operations when connected high to VCC.
• Enables up to four devices to share a common bus through configurable device address inputs.

Memory IC Applications

• Industrial applications requiring low power operation
• Commercial applications optimized for low voltage environments
• Systems needing non-volatile storage for configuration data

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage and package specifications. Confirm the component meets RoHS compliance standards if applicable to your manufacturing process. Ensure the supplier provides valid traceability documentation for quality assurance purposes during the procurement phase.

Memory IC Selection Notes

Select this component for designs requiring 32KB of non-volatile storage with minimal pin count. The 1.8V operating range makes it suitable for battery-powered or low-voltage logic systems. Consider the 100 kHz speed limit at this voltage when designing timing-critical communication interfaces.

Memory IC Part Context

This part belongs to the AT24C256 family of serial EEPROMs, which are designed for space-saving integration in embedded systems. The 'W' indicates an 8-lead JEDEC SOIC package, while '-1.8' specifies the low-voltage operational range. These devices are widely used where data retention and low standby current are critical design constraints.

Memory IC Replacement Considerations

Compatible substitutes include AT24C256N-10SI-1.8 and AT24C256-10SI-1.8, provided they match the 8-lead SOIC package and 1.8V voltage requirements. Verify pin compatibility and electrical characteristics before substitution.
