S-25A640B0A-J8T2U3

Overview

The ABLIC S-25A640B0A-J8T2U3 is an SPI serial E2PROM designed for automotive applications requiring operation up to 125°C. It features a 64 K-bit capacity organized as 8192 words by 8 bits. The device supports a maximum clock frequency of 6.5 MHz and operates within a voltage range of 2.5 V to 5.5 V. It includes page write capabilities of 32 bytes per page, sequential read functions, and hardware/software write protection with selectable block sizes.

Feature Summary

• Supports high-speed SPI communication with frequencies up to 6.5 MHz
• Provides hardware and software write protection mechanisms including block protect settings
• Features CMOS Schmitt inputs on control pins to prevent malfunction
• Includes a hold function to pause serial communications without deselecting the chip

Applications

• Automotive electronic control units (ECUs)
• ADAS domain controllers
• Industrial equipment memory storage
• GNSS antenna amplifier power supply monitoring

Procurement Notes

Verify the specific suffix J8T2U3 corresponds to the 8-Pin SOP (JEDEC) package in tape reel format containing 4000 pieces. Confirm that the 'B' variant designation matches the required 6.5 MHz maximum clock frequency specification rather than the 'A' variant's 5.0 MHz limit. Ensure compliance with AEC-Q100 Grade 1 requirements for your target temperature range.

Selection Notes

Select this component when automotive-grade reliability up to 125°C ambient temperature is required. Choose the B-series over the A-series if system timing demands exceed 5.0 MHz. Verify that the 64 K-bit capacity fits the application data storage needs and that the 8-pin SOP package dimensions align with the PCB layout constraints.

Part Context

This part belongs to the S-25A640 series of SPI serial EEPROMs from ABLIC. It is specifically engineered for harsh environments found in automotive systems. The series offers various package options including SOP, TSSOP, and TMSOP, with the J8T2U3 suffix denoting the standard SOP JEDEC footprint.

Replacement Considerations

S-25A640A0A-J8T2UD is a compatible alternative within the same family but operates at a lower maximum clock frequency of 5.0 MHz.
