Product details
Overview
W25X80VZPIG from Winbond is an 8M-bit (1MB) serial Flash memory IC designed for embedded code storage and data logging in space-constrained systems. It supports Dual Output SPI at up to 75 MHz clock frequency (150 Mbps effective throughput), features uniform 4KB sectors and 64KB blocks, operates from a single 2.7–3.6V supply, and delivers 5 mA active current with 1 µA power-down current. It is commonly used in firmware boot storage for microcontrollers in industrial controllers and IoT edge nodes.
For engineers reviewing the W25X80VZPIG datasheet, W25X80VZPIG pinout, W25X80VZPIG application, or W25X80VZPIG equivalent, key selection criteria include sector granularity (4KB), dual-output read performance, hardware/software write protection via /WP and status register, JEDEC ID compatibility, and SOIC-208-mil package compatibility with legacy PCB footprints.
Technical Context
The W25X80VZPIG implements a standard SPI interface compliant with Modes 0 and 3, and extends functionality with Fast Read Dual Output (3Bh instruction) that repurposes the DIO pin as a second data output during reads-enabling 2× data rate over conventional SPI. Its internal architecture includes a 4096-page (256-byte/page) array organized into 256 erasable 4KB sectors and 16 erasable 64KB blocks.
Write control is enforced through layered protection: hardware-level /WP pin assertion, software-configurable Block Protect (BP2–BP0) and Top/Bottom (TB) bits in the status register, and Status Register Protect (SRP) bit enabling or disabling status register writes based on /WP state. All erase/program operations require prior Write Enable (06h) and automatically clear the Write Enable Latch (WEL) upon completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 M-bit (1,048,576 bytes), organized as 4096 × 256-byte pages |
| Interface | Dual Output SPI: CLK, /CS, DIO (bidirectional), DO (dedicated output); supports Fast Read Dual Output (3Bh) |
| Max Clock Frequency | 75 MHz - enables 150 Mbps effective read throughput using dual-output mode |
| Erase Granularity | 4 KB sectors (256 total) and 64 KB blocks (16 total); allows fine-grained parameter/data partitioning |
| Endurance & Retention | Minimum 100,000 program/erase cycles; data retention ≥ 20 years at +25°C |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic systems without level shifting |
| Operating Temp | −40°C to +85°C - qualified for industrial ambient environments |
Pinout & Package
W25X80VZPIG is packaged in an 8-pin SOIC 208-mil (package code SS), with gull-wing leads and 1.27 mm pitch. This package is pin-compatible with other W25X-series devices in the same footprint and supports reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; device enters standby (high-Z DO, low ICC) when high; must transition high→low before accepting new instructions |
| 2 DO | Serial Data Output | Dedicated output for standard SPI reads; outputs data on falling CLK edge; high-impedance during /HOLD or /CS high |
| 3 /WP | Write Protect Input | Hardware lock for status register writes when SRP = 1; active-low; enables top/bottom array protection independent of software settings |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-impedance PCB connection to minimize noise coupling |
| 5 DIO | Serial Data I/O | Bidirectional SPI data line: input for commands/addresses/writes; output for dual-output reads (3Bh); latched on rising CLK edge |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports SPI Modes 0 and 3; rising edge samples DIO, falling edge clocks DO/DIO output |
| 7 /HOLD | Hold Input | Pauses ongoing SPI transaction while /CS remains low; places DO in high-Z and ignores DIO/CLK; useful for multi-device bus sharing |
| 8 VCC | Power Supply | 2.7–3.6 V nominal; internal voltage regulator ensures stable core operation; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Dual Output SPI Read (3Bh) | Enables 150 Mbps read bandwidth by using DIO as second data lane-critical for fast code shadowing at boot |
| Uniform 4 KB Sector Erase | Allows independent update of configuration parameters or firmware segments without disturbing adjacent data |
| Hardware + Software Write Protection | /WP pin + BP2/BP1/BP0/TB/SRP bits permit hierarchical locking: full chip, top/bottom half, or arbitrary 4KB/64KB regions |
| JEDEC Standard Identification | Returns Manufacturer ID EFh and Device ID 13h (3014h) via ABh/90h/9Fh instructions-ensures interoperability with generic flash programmers |
| Low-Power Power-Down Mode | Reduces current to 1 µA typical; exited via Release Power-down (ABh); preserves memory contents and status register state |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF081A-SSHN-B | 8 M-bit SPI Flash; supports Quad I/O (QPI) but not Dual Output SPI; max clock 85 MHz; different status register map and protection scheme | Lacks dedicated /HOLD pin; uses /RESET instead; no native Fast Read Dual Output instruction | Preferred where QPI interface and higher clock tolerance are needed; requires firmware adaptation for status register and erase commands |
| SST25VF080B-80-4I-SAE | 8 M-bit SPI Flash; supports standard SPI only (no dual/quad modes); 80 MHz max clock; 100K endurance; different JEDEC ID (BFh/8Eh) | No /HOLD or /WP pins; relies solely on software write protection; lacks TB/BP granularity | Suitable for cost-sensitive designs where dual-output speed is unnecessary and simplified command set is preferred |
Compared with AT25DF081A-SSHN-B and SST25VF080B-80-4I-SAE, the W25X80VZPIG uniquely balances dual-output throughput, hardware-assisted write protection, and /HOLD bus arbitration-making it optimal for real-time embedded systems requiring deterministic boot and robust field update capability.

FAQ
What is the maximum SPI clock frequency supported by the W25X80VZPIG?
The W25X80VZPIG supports SPI clock frequencies up to 75 MHz. When using the Fast Read Dual Output (3Bh) instruction, this enables an effective data transfer rate of 150 Mbps. This specification is validated under standard operating conditions (2.7–3.6 V, −40°C to +85°C) and assumes proper signal integrity and termination on the SPI bus. The W25X80VZPIG does not support Quad SPI or higher-speed interfaces beyond this limit.
Does the W25X80VZPIG support hardware write protection independent of software settings?
Yes, the W25X80VZPIG supports hardware write protection via the /WP pin in conjunction with the Status Register Protect (SRP) bit. When SRP = 1 and /WP is driven low, writes to the status register-including Block Protect (BP2–BP0) and Top/Bottom (TB) bits-are disabled. This provides fail-safe protection against unintended configuration changes during power transients or firmware faults, and remains active even if software control is compromised.
What package type is used for the W25X80VZPIG, and is it compatible with other W25X-series devices?
The W25X80VZPIG uses an 8-pin SOIC 208-mil package (package code SS). It shares this footprint with the W25X40 in the same family and is mechanically and electrically pin-compatible with other W25X-series devices in the SS package. However, it is not compatible with the smaller SOIC 150-mil (SN) package used by W25X10/W25X20/W25X40 variants due to differing body width and lead spacing.
How many erase cycles can the W25X80VZPIG endure, and what is its data retention period?
The W25X80VZPIG guarantees a minimum of 100,000 program/erase cycles per sector and provides data retention of at least 20 years at +25°C. Retention is specified under standard storage conditions and may vary slightly with elevated temperature or extended time; however, Winbond's qualification testing confirms compliance across the full industrial temperature range (−40°C to +85°C).
Can the W25X80VZPIG be used in systems requiring JEDEC-standard identification?
Yes, the W25X80VZPIG fully supports JEDEC-standard identification. It responds to the Release Power-down / Device ID (ABh), Read Manufacturer/Device ID (90h), and JEDEC ID (9Fh) instructions, returning Manufacturer ID EFh and Device ID 13h (3014h). This ensures compatibility with generic flash programming tools, automated test equipment, and bootloader frameworks that rely on standardized ID protocols for device detection and configuration.
