S-93A46BD0A-A8T1U3

Memory IC Overview

The S-93A46BD0A-A8T1U3 is a 1 K-bit (64-word × 16-bit) automotive-grade 3-wire serial EEPROM manufactured by ABLIC Inc. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 2.0 MHz. The device features sequential read capabilities, CMOS Schmitt inputs for CS, SK, and DI pins, and a write protect function during low power supply voltage conditions. It is qualified under AEC-Q100 standards and offers an operating temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Automotive qualification with high-temperature operation up to 125°C
• Built-in protection against erroneous writes via clock pulse monitoring
• Low power supply voltage detection prevents data corruption
• Supports sequential reading with automatic address increment

Memory IC Applications

• Automotive control units requiring reliable non-volatile storage
• Systems needing robust data retention in extreme temperatures
• Applications utilizing Microwire bus communication protocols

Memory IC Procurement Notes

Verify the specific package type HSNT-8(2030) matches your PCB footprint requirements. Confirm that the 2.5 V minimum operating voltage aligns with your system's power rail specifications. Ensure compliance with AEC-Q100 Grade 1 reliability standards if required for your automotive application. Check for lead-free and halogen-free certification status before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact 1 K-bit memory solution is needed for automotive environments. The HSNT-8(2030) package provides a small form factor suitable for space-constrained designs. Consider the 2.5 V to 5.5 V operating range to ensure compatibility with your power supply. The 3-wire interface reduces pin count compared to SPI alternatives, simplifying board layout.

Memory IC Part Context

This part belongs to the S-93AxxB series of automotive serial EEPROMs. It shares functional similarities with other members like S-93A56B or S-93A66B but differs in memory capacity. The 'A' suffix indicates the extended temperature range, while 'A8T1' specifies the HSNT-8(2030) tape-and-reel packaging configuration.

Memory IC Replacement Considerations

Direct substitutes include other S-93A46B variants with different packages such as SOP-8 or TSSOP. Cross-brand replacements must match the 3-wire Microwire interface, 1 K-bit capacity, and automotive temperature ratings.
