S-25A320B0A-J8T2U3

Overview

The ABLIC S-25A320B0A-J8T2U3 is a 32 K-bit SPI serial EEPROM designed for automotive applications. It features a 4096 x 8-bit organization and operates within a voltage range of 2.5 V to 5.5 V with a maximum clock frequency of 6.5 MHz. The device supports page writes of 32 bytes and includes hardware/software write protection. It offers an operating temperature range of -40°C to +125°C, 100-year data retention at 25°C, and 3x10^5 cycle endurance at 125°C. Packaged in an 8-pin SOP (JEDEC) tape reel.

Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification and operation up to 125°C
• High-speed SPI interface supporting frequencies up to 6.5 MHz
• Flexible write protection via software status register or hardware WP pin
• Page write capability allowing efficient programming of 32-byte blocks

Applications

• Automotive control unit data storage
• Vehicle configuration parameter retention
• Calibration data logging in electronic systems

Procurement Notes

Verify the specific suffix J8T2U3 corresponds to the 8-Pin SOP JEDEC package and tape reel packing format. Confirm that the B-series designation aligns with the required write time specifications and endurance ratings for your target application environment. Ensure compatibility with the intended SPI controller logic levels.

Selection Notes

Select this component when high-temperature automotive operation and robust data retention are required. The 32 K-bit capacity suits moderate data storage needs compared to smaller variants. Consider the B-series characteristics if longer write times are acceptable for higher endurance margins. Verify package dimensions fit the PCB layout constraints for the 8-pin SOP form factor.

Part Context

This part belongs to the S-25AxxxB series of automotive SPI EEPROMs from ABLIC. It shares architectural similarities with the A-series but may differ in electrical timing parameters like write time. The family provides scalable capacities including 8 K-bit and 16 K-bit options, all utilizing the same pinout and instruction set for design flexibility across different memory requirements.

Replacement Considerations

Direct substitutes include other S-25A320B variants with different packages such as TSSOP or TMSOP. Cross-referencing with S-25A320A models requires checking differences in write time and endurance specifications. Ensure any replacement maintains the 8-pin SOP footprint and compatible SPI command set.
