Product details
Overview
W25P80VSSIG T&R from Winbond is an 8M-bit (1 MByte) serial Flash memory IC designed for embedded code storage and data logging in space-constrained systems. It operates on a single 2.7–3.6 V supply, draws only 4 mA active current and 1 µA in power-down mode, and supports SPI Mode 0/3 up to 50 MHz. Its 8-pin SOIC-208mil (SS) package enables compact PCB layout in microcontroller-based boot loaders and firmware update modules.
For engineers reviewing the W25P80VSSIG T&R datasheet, W25P80VSSIG T&R pinout, W25P80VSSIG T&R application, or W25P80VSSIG T&R equivalent, key selection criteria include its 256-byte page programming time (3.5 ms), sector erase duration (0.6 s), 100,000 program/erase cycles, 20-year data retention, and hardware/software write protection via /WP pin and status register BP/SRP bits.
Technical Context
The W25P80VSSIG T&R implements a standard 4-wire SPI interface (CLK, /CS, DI, DO) with optional /HOLD and /WP control lines. It uses a 4,096-page × 256-byte array architecture organized into 16 sectors of 64 KB each, with dedicated 256-byte parameter page separate from main memory for fast configuration storage.
Its functional behavior is governed by a status register with BUSY, WEL, BP2–BP0, and SRP bits - enabling precise hardware- and software-controlled write protection. All program/erase operations require explicit Write Enable (06h) and are automatically disabled post-execution, ensuring robustness against spurious writes during power transitions or noise events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 M-bit (1,048,576 bytes), organized as 4,096 × 256-byte pages |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic systems without level shifting |
| Max Clock Frequency | 50 MHz - enables high-speed firmware readout and OTA update streaming |
| Page Program Time | 3.5 ms typical - determines minimum latency for incremental firmware patching |
| Sector Erase Time | 0.6 s typical - defines time budget for field-upgradeable module reconfiguration |
| Data Retention | 20 years at +25°C - ensures long-term reliability in unattended industrial deployments |

Pinout & Package
W25P80VSSIG T&R is housed in an 8-pin SOIC-208mil package (Winbond package code SS), pin-compatible with legacy NexFlash NX25P80 devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO to high-Z when high; required low-to-high transition before instruction acceptance |
| 2 DO | Serial Data Output | Tri-state output: data shifted out on CLK falling edge; high-Z during /HOLD or /CS high |
| 3 /WP | Write Protect Input | Hardware lock: disables status register writes when low and SRP=1; prevents accidental firmware corruption |
| 4 GND | Ground Reference | Return path for all I/O and power; must be low-impedance for stable SPI timing and noise immunity |
| 5 DI | Serial Data Input | Instruction/address/data input: latched on CLK rising edge; MSB-first protocol |
| 6 CLK | Serial Clock Input | Timing reference: supports SPI Modes 0 (CLK idle low) and 3 (CLK idle high) |
| 7 /HOLD | Hold Input | Bus arbitration: pauses ongoing SPI transfer when asserted low while /CS is active; preserves internal state |
| 8 VCC | Power Supply | Single 2.7–3.6 V rail; powers core logic and I/O buffers; requires local 0.1 µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Parameter Page | 256-byte dedicated non-volatile area - stores device ID, revision, calibration data with <200 ms erase time, independent of main array |
| Hardware Write Protection | /WP pin + SRP bit combination - provides tamper-resistant lock for bootloader or security keys without software intervention |
| Flexible Sector Protection | BP2–BP0 bits configure 1/16 to full-array protection - enables secure partitioning of firmware, config, and user data regions |
| Power-down Mode | B9h instruction reduces current to 1 µA - extends battery life in portable diagnostics and sensor loggers |
| SPI Mode Compatibility | Supports both Mode 0 and Mode 3 - eliminates need for clock polarity inversion logic in existing MCU designs |
Applications

IC Role / Device Role / Timing Role: Parameter page + protected sectors hold immutable factory settings; /WP pin prevents runtime corruption during power brownouts. Use Value: Ensures consistent device behavior across 20-year lifespan - eliminates need for EEPROM co-location or redundant backup schemes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF081-SSH-T | 8 M-bit SPI Flash; 85 MHz max clock; 2.7–3.6 V; 100K cycles; same 8-pin SOIC-208mil package | Higher speed read (85 MHz vs. 50 MHz); lacks /HOLD pin; different status register map and protection scheme | Preferred where faster boot-time code fetch is critical and /HOLD arbitration is unnecessary. |
| SST25VF080B-80-4I-SAE | 8 M-bit SPI Flash; 80 MHz max clock; 2.7–3.6 V; 100K cycles; 8-pin SOIC-208mil | Supports dual-I/O read; no parameter page; different instruction set (e.g., 0x52 not supported); no /HOLD pin | Chosen when dual-output read acceleration improves system throughput and parameter page functionality is unused. |
Compared with AT25DF081-SSH-T and SST25VF080B-80-4I-SAE, the W25P80VSSIG T&R uniquely combines /HOLD for multi-device SPI sharing, a dedicated parameter page for configuration agility, and full NexFlash NX25P80 compatibility - making it optimal for legacy design refreshes and resource-constrained embedded boot systems.

FAQ
What is the maximum SPI clock frequency supported by the W25P80VSSIG T&R?
The W25P80VSSIG T&R supports a maximum SPI clock frequency of 50 MHz. This rating applies to standard Read Data (03h) and Fast Read (0Bh) operations under recommended operating conditions (2.7–3.6 V, -40°C to +85°C). The device maintains timing compliance across both SPI Mode 0 and Mode 3, allowing direct integration with common microcontrollers without clock polarity translation logic. Higher frequencies are not guaranteed and may result in read errors or command rejection.
Does the W25P80VSSIG T&R include hardware write protection independent of software control?
Yes, the W25P80VSSIG T&R provides hardware write protection via the /WP (Write Protect) 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 protection (BP) bit configuration - are blocked regardless of software commands. This dual-layer mechanism ensures critical firmware or calibration data remains intact during power transients or firmware faults, delivering robustness beyond software-only protection schemes used in the W25P80VSSIG T&R.
How many program/erase cycles does the W25P80VSSIG T&R guarantee?
The W25P80VSSIG T&R guarantees 100,000 program/erase cycles per sector. This endurance rating is specified under standard operating conditions (2.7–3.6 V, -40°C to +85°C) and applies uniformly across all 16 sectors of the 8 M-bit array. Each cycle corresponds to a full sector erase followed by page programming. The W25P80VSSIG T&R maintains this specification throughout its rated temperature range and supports wear leveling algorithms implemented in host firmware to maximize usable lifetime in high-update-rate applications.
What is the purpose of the Parameter Page in the W25P80VSSIG T&R?
The Parameter Page in the W25P80VSSIG T&R is a dedicated 256-byte region physically separate from the main memory array, designed for storing infrequently modified but critical data such as device ID, firmware revision, calibration constants, or network credentials. Its key advantage is independent erase capability - erasing the Parameter Page takes less than 200 ms, versus 0.6 s for a full sector erase. This enables rapid configuration updates without disrupting operational firmware stored elsewhere in the W25P80VSSIG T&R array.
Is the W25P80VSSIG T&R pin-compatible with the NexFlash NX25P80?
Yes, the W25P80VSSIG T&R is fully pin-compatible and functionally equivalent to the NexFlash NX25P80. The datasheet explicitly states "The Winbond W25P80/16/32 are fully compatible with the previous NexFlash NX25P80/16/32 Serial Flash memories." This includes identical pinout (8-pin SOIC-208mil), electrical characteristics, instruction set, timing parameters, and package dimensions - enabling drop-in replacement in legacy designs without PCB or firmware changes. The W25P80VSSIG T&R retains the same SS package code and functional behavior as its NexFlash predecessor.
