S-24C256CI-T8T1U4

Overview

The S-24C256CI-T8T1U4 is a 2-wire serial EEPROM with a capacity of 256 K-bit, organized as 32768 words by 8 bits. It operates within a voltage range of 1.6 V to 5.5 V for reading and 1.7 V to 5.5 V for writing. The device supports clock frequencies up to 1.0 MHz at voltages between 2.5 V and 5.5 V, and 400 kHz at 1.6 V to 2.5 V. It features page write capability of 64 bytes per page and includes an ECC function for error correction on every four bytes. The component is housed in an 8-pin TSSOP package.

Feature Summary

• Integrated Error Correction Code (ECC) function that automatically corrects single-bit errors during read operations across groups of four bytes.
• Hardware write protect functionality enabled via the WP pin or triggered automatically when power supply voltage drops below detection levels.
• Built-in noise suppression filters and Schmitt triggers on input pins to ensure signal integrity in noisy environments.
• Supports acknowledge polling to monitor internal write cycle completion without requiring fixed wait times.

Applications

• Consumer electronics data storage
• Office equipment configuration memory
• Communications devices parameter retention

Procurement Notes

Verify the specific ordering suffix matches the required package type and environmental compliance standards. Confirm that the application environment falls within general electronic device usage categories. Contact the manufacturer directly if the intended use involves medical equipment or automotive systems such as engine control units or keyless entry modules.

Selection Notes

Select this component for applications requiring non-volatile storage with high endurance and low current consumption. Ensure the system design accommodates the specific voltage thresholds for read and write operations. Consider the page write size when designing firmware to optimize write efficiency and minimize wear on the memory cells.

Part Context

This part belongs to the S-24C256C series of 2-wire serial E2PROMs manufactured by ABLIC Inc. The series is designed for low-power applications and offers wide operating voltage ranges. The specific model indicates an industrial temperature grade and a TSSOP-8 surface mount package.

Replacement Considerations

Compatible substitutes include other 256 Kbit I2C EEPROMs from manufacturers such as Microchip, provided they support similar voltage ranges and interface timings. Verify pin compatibility and electrical characteristics before substitution.
