BY25Q128ESWIG(R)

Memory IC Overview

The BY25Q128ESWIG(R) is a 128M-bit SPI NOR Flash memory by BYTe Semiconductor, housed in an 8-WSON package. It supports Standard, Dual, and Quad SPI interfaces with clock rates up to 120MHz and data transfer speeds reaching 480Mbits/s in Quad I/O mode. Operating on a single 2.7V to 3.6V supply, it features sector/block erase capabilities, page programming up to 256 bytes, and flexible software/hardware write protection including security registers.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI protocols for high-speed data transfer and Execute-In-Place (XIP) operations.
• Provides comprehensive write protection via hardware /WP pin, software block protect bits, and three 1024-byte security registers with OTP locks.
• Features flexible memory architecture allowing sector (4KB), block (32/64KB), and chip erase operations with suspend/resume capability.

Memory IC Applications

• Firmware storage for microcontrollers and embedded systems
• Code execution in place (XIP) applications
• Data logging and configuration storage

Memory IC Procurement Notes

Verify the specific suffix 'WIG(R)' against the manufacturer's official ordering guide to confirm the exact package type (WSON) and tape/reel packaging specifications. Ensure compatibility with host system voltage levels within the 2.7V-3.6V range and check for moisture sensitivity level requirements during handling.

Memory IC Selection Notes

Select this component when a compact 8-pin surface-mount footprint is required for 128Mb capacity. It is suitable for designs needing Quad SPI performance up to 480Mbits/s and robust data protection features. Compare electrical characteristics such as active current and power-down current against system power budget constraints.

Memory IC Part Context

This part belongs to the BY25Q128ES family of Serial Peripheral Interface NOR Flash memories. The family offers various package options including SOP8 and USON8. The WIG(R) designation specifically indicates the WSON package variant with reel packaging, distinguishing it from tube-packed or different package versions within the same density series.

Memory IC Replacement Considerations

Cross-reference with other 128Mb SPI NOR Flash parts from manufacturers like GigaDevice (e.g., GD25Q128) or Micron (e.g., MT25QL128). Verify pinout compatibility, command set adherence, and voltage ranges before substitution to ensure functional equivalence in the target application.
