S-24C02DI-J8T1U5

Overview

The S-24C02DI-J8T1U5 is a 2-kbit serial EEPROM manufactured by ABLIC Inc. It features a 2-wire I2C interface with a maximum clock frequency of 1 MHz at VCC levels between 2.5 V and 5.5 V, or 400 kHz across the full 1.7 V to 5.5 V range. The memory organization is 256 words by 8 bits. Operating voltage ranges from 1.7 V to 5.5 V for both read and write operations. The device supports page writes of up to 8 bytes per page and sequential reads. It includes Schmitt triggers and noise filters on input pins, a write protect function, and an endurance rating of 10^6 cycles per word. Data retention is specified at 100 years.

Feature Summary

• Supports high-speed operation up to 1 MHz at elevated supply voltages
• Includes hardware write protection via dedicated pin control
• Features built-in noise suppression on communication lines
• Provides long-term data retention capabilities

Applications

• Consumer electronics
• Office equipment
• Communications devices

Procurement Notes

Verify the specific ordering suffix J8T1U5 corresponds to the 8-Pin SOP (JEDEC) package and tape reel packing configuration. Confirm that the industrial temperature grade (-40°C to +85°C) meets system requirements. Ensure compatibility with the host controller's I2C pull-up resistor values and voltage levels before finalizing procurement.

Selection Notes

Select this component when a 2-kbit non-volatile storage solution is required in an 8-pin surface-mount package. It is suitable for applications needing multiple slave addresses on a single bus via configurable address pins. Consider the 1 MHz speed capability if operating above 2.5 V. Verify that the 8-byte page write size aligns with the application's data update patterns.

Part Context

This part belongs to the S-24C02D series of 2-wire serial E2PROMs. It shares architectural similarities with higher capacity variants like the S-24C04D, S-24C08D, and S-24C16D, though address pin availability decreases as capacity increases. The 'I' designation indicates the industrial temperature range, while 'J8T1' specifies the SOP-8 tape packaging.

Replacement Considerations

Direct replacements within the same family include other S-24C02D variants with different packages such as TSSOP or SOT-23-5. Cross-manufacturer equivalents may require verification of I2C timing parameters and voltage thresholds.
