Product details
Overview
W25Q80BLSSIG from Winbond is an 8M-bit (1MB) serial NOR flash memory IC designed for code storage and execution in space-constrained embedded systems. It supports Standard, Dual, and Quad SPI interfaces, operates from 2.3V to 3.6V, delivers up to 200MHz equivalent data transfer in Quad I/O mode, and features 4KB uniform sectors for flexible firmware and parameter storage in microcontroller boot loaders.
For engineers reviewing the W25Q80BLSSIG datasheet, W25Q80BLSSIG pinout, W25Q80BLSSIG application, or W25Q80BLSSIG equivalent, key selection criteria include Quad SPI XIP capability, hardware write protection via /WP and /HOLD pins, JEDEC ID and SFDP register support, 100,000+ program/erase cycles, and compatibility with industrial temperature range (-40°C to +85°C) designs.
Technical Context
The W25Q80BLSSIG implements a SPI command set compliant with Mode 0 and Mode 3 clock polarity/idle states, enabling interoperability with diverse host controllers. Its dual- and quad-I/O modes rely on bidirectional IO0–IO3 pins activated by setting the non-volatile Quad Enable (QE) bit in Status Register-2 - a prerequisite for Fast Read Quad I/O (EBh) and Word Read Quad I/O (E7h) instructions.
Internal architecture includes a 256-byte page buffer, uniform 4KB sector erase granularity (256 sectors), 32KB/64KB block erase options (16 blocks), and dedicated security registers with OTP lock capability. Write protection combines volatile/non-volatile status bits (BP2–BP0, TB, SEC, CMP, SRP1/SRP0) with hardware /WP pin control and power-down instruction locking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L8006EM1I-12G | 8 M-bit, 3V, SOIC-8 208-mil; supports standard/Dual SPI only (no Quad I/O or QE bit) | Lacks Quad SPI XIP and SFDP register; limited to legacy SPI controllers without Quad mode support | Select when Quad interface is unnecessary and cost sensitivity outweighs performance and future-proofing needs |
| S25FL008KAGMFI011 | 8 M-bit, 3V, SOIC-8 208-mil; supports Quad SPI with QPI mode and configurable dummy cycles | Includes QPI (quad peripheral interface) command set and deeper power-down modes (<100 nA) | Prefer for ultra-low-power battery-operated devices where extended sleep current matters more than XIP latency |
Compared with MX25L8006EM1I-12G, W25Q80BLSSIG adds Quad SPI XIP and SFDP for plug-and-play host integration; versus S25FL008KAGMFI011, it offers lower active current and simpler command set but lacks QPI and sub-µA deep-sleep modes.

FAQ
What is the maximum SPI clock frequency supported by the W25Q80BLSSIG?
The W25Q80BLSSIG supports up to 50 MHz for standard SPI clock input. In Dual SPI mode (e.g., Fast Read Dual I/O), this yields an effective 100 MHz data rate; in Quad SPI mode (e.g., Fast Read Quad I/O), it achieves 200 MHz equivalent throughput. These rates assume proper signal integrity, load capacitance ≤10 pF, and compliance with AC timing specifications in the official Winbond datasheet revision G1.
Does the W25Q80BLSSIG support execute-in-place (XIP) operation?
Yes, the W25Q80BLSSIG supports true XIP via its Continuous Read Mode and Quad SPI instructions like Fast Read Quad I/O (EBh). When configured with the Quad Enable (QE) bit set, it delivers low-overhead sequential access - as few as 8 clock cycles to address memory - enabling direct code execution from flash without RAM buffering in compatible microcontrollers.
How is hardware write protection implemented on the W25Q80BLSSIG?
The W25Q80BLSSIG implements hardware write protection using the /WP (pin 3) signal, which - when held low - prevents writes to the status register regardless of software commands. This function is active only when the Quad Enable (QE) bit is cleared (QE=0); when QE=1, /WP becomes IO2 and hardware protection is disabled. Full array protection also requires correct configuration of BP2–BP0, TB, and SRP bits.
What package type does the W25Q80BLSSIG use, and is it RoHS-compliant?
The W25Q80BLSSIG uses an 8-pin SOIC 208-mil package (package code SS), with gull-wing leads and Pb-free, RoHS-compliant finish. Its dimensions are 8.8 mm × 4.0 mm × 1.8 mm (L × W × H), and it is rated for reflow soldering per J-STD-020 moisture sensitivity level 3 (MSL3).
Can the W25Q80BLSSIG be used in industrial temperature applications?
Yes, the W25Q80BLSSIG is specified for operation from -40°C to +85°C, making it suitable for industrial control, building automation, and outdoor telemetry applications. Its electrical characteristics - including 2.3V to 3.6V supply range, 4 mA active current, and <1 µA power-down current - are guaranteed across this full temperature range per Winbond's datasheet revision G1.
