W25Q80BLSSIG TR

Memory IC Overview

The W25Q80BLSSIG TR is an 8M-bit (1M-byte) Serial NOR Flash memory from Winbond's SpiFlash family, designed for systems with limited space and power. It operates on a single 2.3V to 3.6V supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 50MHz. The device features uniform 4KB sectors and 32KB/64KB blocks, advanced security registers, and a 64-bit unique serial number. Packaged in an 8-pin SOIC-8 (208-mil) format, it offers high performance with low active current consumption.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI operations for flexible data transfer rates
• Features uniform 4KB sector erase architecture for efficient parameter storage
• Includes hardware and software write protection mechanisms with top/bottom block control
• Provides a 64-bit Unique Serial Number for device identification

Memory IC Applications

• Code shadowing to RAM
• Execute In Place (XIP) applications
• Voice, text, and data storage

Memory IC Procurement Notes

Verify the specific package width associated with the SS suffix against the manufacturer datasheet, as it denotes an 8-pin SOIC variant. Confirm that the TR suffix indicates tape and reel packaging suitable for automated assembly processes. Ensure compatibility with the required voltage range of 2.3V to 3.6V for your target system design.

Memory IC Selection Notes

Select this component when a balance of moderate speed and low power consumption is required for code execution or data logging. It is suitable for designs needing robust write protection features and uniform sector sizes. Consider alternative packages like VSOP or USON if board space constraints are tighter than what the SOIC-8 form factor allows.

Memory IC Part Context

This part belongs to the W25Q80BL series, which is distinct from the W25Q80BV and W25Q80DV families due to its specific 2.5V nominal operating voltage characteristics. While sharing the same 8M-bit capacity and instruction set, the BL series is optimized for different power supply environments compared to the 3V DV series or 1.8V EW series.

Memory IC FAQ

How does the Quad Enable bit affect pin functionality?

When the non-volatile Quad Enable (QE) bit in Status Register-2 is set, the /WP pin functions as IO2 and the /HOLD pin functions as IO3 to support Quad SPI instructions.

What is the minimum erasable unit size?

The device supports uniform 4KB sector erases, allowing for granular data modification without affecting the entire chip or larger blocks.
