Memory IC Procurement Notes

Verify the manufacturer origin as this component was originally manufactured by SANYO Semiconductor Co., Ltd. under license from Silicon Storage Technology, Inc. Confirm package availability in MFP8 or DIP8 formats. Ensure compatibility with the fixed internal slave address configuration (S0=0, S1=0, S2=0) during system design.

Memory IC Selection Notes

Select this component for designs requiring a fixed slave address without external address pins. It is suitable for applications needing 16-byte page write efficiency and robust noise immunity through integrated input filters. Verify that the operating voltage range of 2.7V to 5.5V aligns with the system power supply requirements.

Memory IC Part Context

This device belongs to the 32-kbit serial EEPROM category utilizing CMOS technology. It implements a symmetric memory array configuration for high reliability.
