Product details
Overview
W25Q80BLSSIG TR from Winbond is an 8M-bit (1 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 50 MHz clock rate, 4 KB uniform sector architecture, and XIP-capable continuous read mode - used for code storage, firmware boot, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q80BLSSIG TR datasheet, W25Q80BLSSIG TR pinout, W25Q80BLSSIG TR application, or W25Q80BLSSIG TR equivalent, key selection considerations include Quad SPI enable (QE bit), /WP and /HOLD dual-role behavior in Quad mode, 2.3–3.6 V supply compatibility, and JEDEC-compliant 64-bit unique ID support.
Technical Context
The W25Q80BLSSIG TR implements a SPI-compatible command set with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit = 1 in Status Register-2 and repurposes /WP and /HOLD as IO2 and IO3. It supports Fast Read Quad I/O (EBh) at up to 200 MHz equivalent data rate.
Its memory array comprises 4,096 × 256-byte pages organized into 256 erasable 4 KB sectors and 16 erasable 64 KB blocks, with erase/program suspend/resume capability, volatile/non-volatile status register bits, and SFDP register for discoverable parameters - enabling flexible firmware update and secure configuration storage.

Pinout & Package
W25Q80BLSSIG TR is packaged in 8-pin SOIC 208-mil (package code SS), with gull-wing leads and standard JEDEC MS-012AC footprint. Pin 1 marked by notch or dot; pin 4 = GND, pin 5 = VCC, pin 6 = /HOLD (IO3 in Quad mode), pin 7 = DI (IO0), pin 8 = CLK.
| Pin/Terminal | Circuit Role | Design Meaning |

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, 3 V, SOIC-8; supports Standard/Dual SPI only - no Quad I/O or QE bit | Lacks XIP-optimized continuous read and Quad throughput; suitable for cost-sensitive legacy designs | Choose when Quad SPI is unnecessary and JEDEC ID/unique serial number not required |
| S25FL008KAGMFI010 | 8 M-bit, 2.7–3.6 V; Quad SPI with QPI mode; includes 4-byte address support (beyond W25Q80BL's 3-byte limit) | Better scalability for future firmware growth; supports larger address space but requires QPI initialization | Prefer for new designs needing >16 MB expandability path or enhanced security features like secure wipe |

FAQ
What is the package type and lead finish of W25Q80BLSSIG TR?
W25Q80BLSSIG TR uses an 8-pin SOIC 208-mil package (package code SS) with matte tin (Sn) lead finish, compliant with RoHS and lead-free assembly requirements. The body dimensions are 8.8 mm × 4.0 mm × 1.8 mm, and it is rated for reflow per J-STD-020C.
Does W25Q80BLSSIG TR support Quad SPI out of the box?
No - W25Q80BLSSIG TR requires the Quad Enable (QE) bit in Status Register-2 to be set to 1 to activate Quad SPI mode. Until configured, /WP and /HOLD function as hardware write protect and hold inputs. The QE bit is non-volatile and persists across power cycles once written.
How many program/erase cycles does W25Q80BLSSIG TR guarantee?
W25Q80BLSSIG TR guarantees ≥100,000 program/erase cycles per 4 KB sector, validated per JEDEC JESD22-A117. This endurance applies to all sectors across the full temperature range (–40°C to +85°C) and voltage range (2.3 V to 3.6 V).
Can W25Q80BLSSIG TR be used for execute-in-place (XIP) applications?
Yes - W25Q80BLSSIG TR supports true XIP via its Continuous Read Mode, which minimizes instruction overhead to as few as 8 clocks per 24-bit address and enables efficient sequential access. Fast Read Quad I/O (EBh) further improves throughput for real-time code execution.
Is the 64-bit unique ID accessible without special commands?
Yes - the 64-bit unique serial number is read using the standard Read Unique ID Number instruction (4Bh), requiring only a 5-byte command sequence (0x4B + 4 dummy bytes). No unlock sequence or status register modification is needed, and it is guaranteed unique per die.
