BY25Q20BLZIG(R)

Memory IC Overview

The BY25Q20BL is a 2M-bit SPI NOR Flash memory designed for high-volume consumer applications. It supports Standard, Dual, and Quad SPI interfaces with read speeds up to 85MHz. The device operates on a single low voltage supply ranging from 1.65V to 2.0V. It features flexible erase architecture with 4KB sectors and 32/64KB blocks. Key specifications include 10k program-erase cycles typical endurance, 20-year data retention at +55°C, and three 512-byte security registers with OTP lock.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes with software reset capability
• Operates on a single low voltage supply ranging from 1.65V to 2.0V
• Features flexible erase architecture with 4KB sectors and 32/64KB blocks
• Includes hardware and software write protection with security registers

Memory IC Applications

• Code shadowing from Flash memory into embedded or external RAM
• High-volume consumer-based applications requiring code execution
• Data storage utilizing the flexible erase architecture

Memory IC Procurement Notes

Verify the specific package type required, as the datasheet lists USON8, DFN8, and USON6 options. Confirm that the host system voltage aligns with the 1.65V to 2.0V operating range. Ensure compatibility with the selected SPI mode, noting that Quad SPI and Hold functions are unavailable in the 6-pin package configuration.

Memory IC Selection Notes

Select this component when a low-voltage operation between 1.65V and 2.0V is mandatory. It is suitable for designs prioritizing power efficiency over high-speed performance compared to 3.3V devices. Consider the package constraints if Quad SPI or hardware hold/reset functions are required, as these are not supported in the 6-pin variant.

Memory IC Part Context

The BY25Q20BL belongs to the BYTe Semiconductor BY25Qxx series of SPI NOR Flash memories. This series is characterized by its support for multiple SPI interface modes and flexible erase structures. The BL suffix typically denotes the specific voltage range and feature set optimized for low-power consumer electronics.
