Product details
Overview
W25Q80BVDAIG TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz clock capability, 4 KB uniform sector architecture, and hardware/software write protection. It operates from 2.5 V to 3.6 V, draws 4 mA active current and <1 µA in power-down mode, and is used for code storage, XIP execution, and firmware parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q80BVDAIG TR datasheet, W25Q80BVDAIG TR pinout, W25Q80BVDAIG TR application, or W25Q80BVDAIG TR equivalent, key selection considerations include Quad SPI enable (QE bit), /WP and /HOLD pin reassignment in Quad mode, 4 KB sector granularity for data logging, and JEDEC-compliant identification (9Fh, 90h, 4Bh).
Technical Context
The W25Q80BVDAIG TR implements a SPI command-set compatible with Modes 0 and 3, supports continuous read mode with ≤8-clock instruction overhead, and enables true execute-in-place (XIP) operation via Fast Read Quad I/O (EBh) at up to 416 MHz effective throughput. Its internal block diagram integrates a 256-byte page buffer, SFDP register, and three 256-byte security registers with OTP locks.
Quad SPI functionality requires non-volatile setting of the QE bit in Status Register-2; once enabled, /WP becomes IO2 and /HOLD becomes IO3, disabling their dedicated hardware protection roles. Erase/program suspend/resume (75h/7Ah) and 64-bit unique serial number per device are implemented in silicon and verified across all package variants including DA (PDIP 300-mil).

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L8006EM1I-12G | 8 M-bit, 104 MHz max clock, SOIC-8 only; no USON/WSON options; lacks SFDP register | No continuous read mode or Quad I/O wrap support; lower XIP efficiency | Choose for cost-sensitive designs where Quad SPI and SFDP are not required |
| S25FL008KAGMFI010 | 8 M-bit, 80 MHz max clock; supports Octal DTR mode; includes ECC and configurable reset vector | Better error resilience and boot flexibility; higher pin count (16-pin SOIC) | Choose when system-level reliability (ECC) or flexible boot vector mapping is mandatory |

FAQ
What is the package type and lead finish of W25Q80BVDAIG TR?
W25Q80BVDAIG TR uses an 8-pin PDIP 300-mil package (package code DA) with lead-free, RoHS-compliant finish. The "TR" suffix indicates tape-and-reel packaging for automated SMT assembly. Pin 1 is marked with a notch or dot, and the device meets JEDEC MS-001 standards for PDIP mechanical dimensions and thermal profile compatibility.
Does W25Q80BVDAIG TR support Quad SPI by default?
No, W25Q80BVDAIG TR requires explicit enabling of Quad SPI mode via the non-volatile Quad Enable (QE) bit in Status Register-2 (bit 1). Until QE=1 is written, /WP and /HOLD remain dedicated hardware protection pins. After QE is set, those pins become IO2 and IO3, and instructions like Fast Read Quad I/O (EBh) become functional.
How does the /WP pin function differ between Standard and Quad SPI modes on W25Q80BVDAIG TR?
In Standard SPI mode, /WP (Pin 3) provides hardware write protection for the status register when held low. In Quad SPI mode (QE=1), /WP is reassigned as bidirectional IO2 and loses its dedicated /WP function. Software-based protection via BP bits and SRP0/SRP1 remains fully available regardless of mode.
What is the minimum instruction overhead for random access reads on W25Q80BVDAIG TR?
Using Continuous Read Mode with Fast Read Quad I/O (EBh), W25Q80BVDAIG TR achieves as few as 8 clock cycles of instruction overhead to initiate a read - significantly less than standard SPI's 24+ clocks. This enables efficient XIP execution and reduces CPU wait states during code fetch from flash.
Can W25Q80BVDAIG TR be used in automotive applications?
W25Q80BVDAIG TR is rated for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q100 qualified. For automotive infotainment or body control modules requiring qualification, Winbond's AEC-Q100-compliant W25Q80DV variant (same density, enhanced reliability testing) is recommended instead of W25Q80BVDAIG TR.
