BY25Q16BLMIG(R)

Memory IC Overview

The BY25Q16BL is a 16M-bit SPI NOR Flash memory by BYTe Semiconductor. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 108MHz for Fast Read. Operating voltage ranges from 1.65V to 2.0V. The device features flexible erase architecture with 4KB sectors and 32/64KB blocks. Program/Erase times are typically 2ms for pages and 8ms for sectors/blocks/chips. It includes hardware/software write protection, three 512-byte security registers, and operates within -40°C to +85°C.

Memory IC Procurement Notes

Verify the specific package variant (SOP8 150mil, SOP8 208mil, or USON8) required for your design against the datasheet's order information section. Confirm that the system power supply strictly adheres to the 1.65V-2.0V range, as this model differs from standard 3.3V parts. Ensure compatibility with the specified temperature range of -40°C to +85°C for industrial or commercial use cases.

Memory IC Selection Notes

Select this component when a lower operating voltage (1.65V-2.0V) is required compared to standard 3.3V flash memories. It is suitable for applications needing code execution via shadowing or efficient data storage with flexible block sizes. Consider the available packages (SOP8 or USON8) based on board space constraints. Verify interface speed requirements against the 108MHz Fast Read capability.

Memory IC Part Context

The BY25Q16BL belongs to the BY25Q series of SPI NOR Flash memories manufactured by BYTe Semiconductor. This series is designed for high-volume consumer applications. The BL suffix typically denotes the specific voltage range and feature set optimized for low-power operation. It shares architectural similarities with other BY25Q models but is distinct in its voltage specifications and pin configurations.

Memory IC Replacement Considerations

Direct replacements must match the 1.65V-2.0V operating voltage range. Models like GD25Q16ESIGR operate at 2.7V-3.6V and are not electrically compatible without level shifting. Check pinout compatibility for SOP8 or USON8 packages if substituting with other manufacturers' 16Mbit parts.
