BY25Q20BLAIG(R)

Memory IC Overview

The BY25Q20BLAIG(R) is a 2M-bit SPI NOR Flash memory manufactured by BYTe Semiconductor. It operates on a single low voltage supply ranging from 1.65V to 2.0V, making it suitable for low-power applications. The device supports Standard, Dual, and Quad SPI interfaces with clock rates up to 85MHz for fast read operations. It features flexible erase architectures including 4KB sectors and 32/64KB blocks, along with hardware and software write protection mechanisms.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI communication modes with high-speed data transfer capabilities.
• Operates within a low-voltage range of 1.65V to 2.0V for efficient power consumption.
• Includes comprehensive write protection via hardware pins and software commands.
• Features flexible erase granularity with 4KB sectors and 32/64KB blocks.

Memory IC Applications

• Code shadowing in consumer electronics
• Data storage in embedded systems
• Firmware storage for IoT devices

Memory IC Procurement Notes

Verify the specific package variant (USON-8 or USON-6) required for your design, as pinout functions differ between packages. Confirm that the 1.65V-2.0V operating voltage aligns with your system's power rails. Ensure the selected package supports the necessary interface modes, noting that Quad SPI and Hold/Reset functions are unavailable in the 6-pin configuration.

Memory IC Selection Notes

Select this component when a low-voltage operation between 1.65V and 2.0V is mandatory. It is appropriate for designs requiring small form factors using USON packages. Consider the 6-pin package only if Quad SPI and advanced control signals like /WP and /HOLD are not needed. Verify thermal requirements for industrial temperature ranges if applicable.

Memory IC Part Context

The BY25Q20BL series belongs to BYTe Semiconductor's 2M-bit SPI NOR Flash family. It is designed for high-volume consumer applications where code execution and data storage are required. The device integrates JEDEC standard IDs and security registers, offering a compact solution for firmware storage in space-constrained electronic devices.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other manufacturers requires verifying voltage compatibility (1.65V-2.0V vs standard 2.7V-3.6V) and pinout configurations.

Memory IC FAQ

Is the Quad SPI function available in all packages?

No, Quad SPI operation is not available in the 6-pin package. It is supported in the 8-pin packages (USON-8/SOP-8).

What is the default state of the Quad Enable (QE) bit?

The default state of the QE bit is 0, which enables the /WP and /HOLD pins. Setting it to 1 enables Quad IO2 and IO3 pins.
