BY25Q40GWTIG(R)

Memory IC Overview

The BY25Q40GWTIG(R) is a 4M-bit SPI NOR Flash memory by BYTe Semiconductor, housed in an USON-8 (2x3mm) package. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 80MHz for read operations. The device operates on a single supply voltage ranging from 1.65V to 3.6V. Key electrical parameters include a maximum active current of 3mA and a power-down current of 0.6uA. It features flexible erase architectures with 4KB sectors and 32/64KB blocks, supporting page programs up to 256 bytes. Endurance is rated at 10k program-erase cycles with 20-year data retention.

• Includes hardware and software write protection with security registers
• Operates on a single low-voltage supply ranging from 1.65V to 3.6V

Memory IC Applications

• Code shadowing into embedded or external RAM for execution
• Data storage applications requiring flexible erase granularity
• High-volume consumer-based electronic devices

Memory IC Procurement Notes

Verify the specific suffix 'TIG' against 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. Confirm that the required SPI mode (Standard, Dual, or Quad) aligns with the controller's capabilities and that the Quad Enable bit is properly configured if high-speed access is needed.

Memory IC Selection Notes

Select this component for applications requiring compact surface-mount packaging and low-power operation. The USON-8 package suits space-constrained designs. Consider the 1.65V minimum voltage for battery-powered systems. Ensure the host controller supports the necessary SPI instructions for desired performance levels, particularly for Quad I/O operations which require setting the QE bit.

Memory IC Part Context

This part belongs to the BY25Q40GW series of 4M-bit SPI NOR Flash memories. It shares core functional specifications with other variants in the family but differs in physical packaging and potentially environmental ratings based on its suffix. The USON-8 package provides a small footprint suitable for modern portable electronics.

Memory IC Replacement Considerations

Check for compatible parts within the same density and interface family. Verify pinout compatibility and voltage ranges before substitution. Ensure any replacement supports the required Quad SPI mode if applicable.
