BY25Q40GWUIG(R)

Memory IC Overview

The BY25Q40GWUIG(R) is a 4M-bit SPI NOR Flash memory by BYTe Semiconductor in an USON-8 (2x3mm) package. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 80MHz for non-standard reads and 50MHz for normal reads. The device operates on a single supply voltage of 1.65V to 3.6V. Key electrical parameters include a maximum active current of 3mA and a power-down current of 0.6uA. Program/Erase times are typically 2ms for pages and 8ms for sectors/blocks/chips. It features flexible architecture with 4KB sectors and 32/64KB blocks.

Memory IC Feature Summary

Supports Standard, Dual, and Quad SPI modes with software reset capability
Includes hardware and software write protection with security registers
Features program and erase suspend/resume functions
Offers low power consumption with standby mode

Memory IC Applications

Code shadowing from flash to embedded or external RAM
Data storage applications requiring flexible erase granularity
Consumer-based high-volume electronic devices

Memory IC Procurement Notes

Verify the specific suffix 'UIG' against the manufacturer's official ordering information to confirm package type and temperature range. Ensure compatibility with host system voltage levels within the 1.65V to 3.6V operating range. Check for required decoupling capacitors near VCC/VSS pins as recommended in the datasheet for stable operation.

Memory IC Selection Notes

Select this component when a compact USON-8 footprint is required for 4M-bit storage. Consider its support for Quad SPI if higher data throughput is needed compared to standard SPI. Evaluate the 1.65V minimum supply voltage requirement against the system's power rail capabilities. Verify that the industrial temperature range (-40℃ to +85℃) meets environmental specifications.

Memory IC Part Context

This part belongs to the BY25Q40GW series of SPI NOR Flash memories. It shares architectural similarities with other parts in the family but differs in packaging and potentially thermal characteristics due to the USON-8 form factor. It is designed for applications needing efficient code execution and data storage in space-constrained environments.
