Memory IC Procurement Notes

Verify the specific ordering suffix 'T' corresponds to the Reel packaging format required for your assembly line. Confirm that the 'E' designation aligns with the necessary automotive-grade temperature specifications (-40°C to +125°C). Ensure the voltage requirements match your system's 1.7V to 2.2V operating range before finalizing procurement.

Memory IC Selection Notes

Select this part when high-speed serial access via SDI or SQI is required alongside strict automotive reliability standards. The low-voltage operation makes it suitable for power-constrained embedded designs. Verify compatibility with the host microcontroller's serial interface capabilities and ensure the 8-lead SOIC footprint fits the PCB layout constraints.

Memory IC Part Context

This component belongs to the 23A1024/23LC1024 family of 1 Mbit Serial SRAMs. The primary distinction within this family lies in the supply voltage ranges and temperature grades. The 23A series operates at lower voltages compared to the 23LC series, while the E-temp variant provides extended automotive reliability over the standard Industrial grade.

Memory IC Replacement Considerations

The 23LC1024T-E/SN serves as a functional replacement if the application can accommodate a higher supply voltage range of 2.5 V to 5.5 V. Both devices share identical pinouts, memory organization, and interface protocols.
