Memory IC Procurement Notes

Verify the specific ordering suffix 'SIG' against the manufacturer's official documentation to confirm package type (SOP-8) and tape/reel specifications. Ensure the required operating voltage range of 1.65 V to 2.0 V aligns with your system design, as this part does not support standard 3.3 V operation.

Memory IC Selection Notes

Select this component when a low-voltage (1.65 V–2.0 V) supply is mandatory. It is suitable for designs needing Quad SPI speeds up to 108 MHz and robust security features like OTP lockable security registers. Verify that the host system can accommodate the specific 8-pin package options provided.

Memory IC Part Context

This part belongs to the BY25Q16BL series of 16 Mbit SPI NOR Flash memories. It is designed for high-volume consumer applications where efficient memory usage and low power consumption are critical. The series emphasizes flexibility through its uniform sector and block erase architecture.
