S-25A128B0A-J8T2U3

Overview

The S-25A128B0A-J8T2U3 is an SPI serial EEPROM with a capacity of 128 K-bit (16384 words x 8-bit). It operates within a voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 6.5 MHz. The device features page write capabilities of 64 bytes per page and sequential read functions. It includes hardware and software write protection, supporting 25%, 50%, or 100% block protection. Endurance is rated at 1 million cycles at +25°C and 300,000 cycles at +125°C. Data retention is specified as 100 years at +25°C and 50 years at +125°C. It is qualified under AEC-Q100 for automotive applications.

Feature Summary

• Supports high-speed SPI communication with maximum frequency of 6.5 MHz
• Includes built-in low power supply voltage detection to prevent malfunction during power drops
• Offers flexible write protection via status register bits and dedicated WP pin
• Features hold function to pause serial communications without deselecting the chip

Applications

• Automotive control units requiring operation up to +125°C
• Medical equipment data storage
• Industrial systems needing high endurance and reliability

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as J8T2 denotes SOP and T8T2 denotes TSSOP. Confirm AEC-Q100 qualification details directly with the manufacturer for automotive compliance requirements. Ensure design accounts for the absence of internal pull-up resistors on input pins to prevent floating states.

Selection Notes

Select this component when automotive-grade temperature stability up to +125°C is required. It is suitable for designs needing robust write protection mechanisms against accidental modification. Consider the 64-byte page write size for efficiency in data logging applications. Verify voltage compatibility within the 2.5 V to 5.5 V range for system integration.
