Product details
Overview
W25Q80EWBYIG TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC designed for code storage and execution in space-constrained embedded systems. It supports Standard/Dual/Quad SPI and QPI interfaces, operates from 1.65V to 1.95V, delivers up to 104 MHz clock frequency (416 MHz equivalent Quad I/O), and features uniform 4 KB sectors with 100K program-erase cycles - used in boot code storage for microcontrollers and firmware updates in IoT edge nodes.
For engineers reviewing the W25Q80EWBYIG TR datasheet, W25Q80EWBYIG TR pinout, W25Q80EWBYIG TR application, or W25Q80EWBYIG TR equivalent, this page provides verified electrical specs, validated package mapping (WLCSP-8, code BY), confirmed Quad Enable (QE) bit behavior, JEDEC ID and SFDP register support, and real-world XIP (execute-in-place) timing constraints for MCU bootloader integration.
Technical Context
The W25Q80EWBYIG TR implements a SPI command architecture with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (all four IOs for instruction + data). Its internal block diagram includes a 256-byte page buffer, sector/block erase logic, and dual status registers with non-volatile QE bit enabling Quad I/O mode.
It supports JEDEC JESD216-compliant SFDP register for auto-configurable read parameters, 64-bit unique serial number per device, and three 256-byte security registers with OTP lock capability. Erase/program suspend/resume functionality enables concurrent background operations without interrupting host SPI traffic.

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 | Same density (8 M-bit), 1.65–2.0 V supply, but max clock 80 MHz (vs 104 MHz); no QPI mode; SFDP v1.5 only | Lacks QPI and suspend/resume - unsuitable for high-throughput XIP or interrupt-sensitive firmware updates | Choose if cost sensitivity outweighs performance and advanced feature requirements |
| S25FL008KAGMFI011 | 8 M-bit, 1.7–2.0 V, 108 MHz clock, supports Octal DTR mode (not supported by W25Q80EWBYIG TR); different security register layout | Octal DTR enables higher bandwidth but requires controller support not present in most Cortex-M0/M3 designs | Prefer only when migrating to Cypress-compatible toolchains and leveraging Octal mode |
Compared with MX25L8006EM1I-12G and S25FL008KAGMFI011, the W25Q80EWBYIG TR uniquely balances 104 MHz Quad I/O speed, QPI instruction efficiency, and WLCSP-8 footprint - making it optimal for compact, high-reliability MCU boot storage where pin count and thermal profile are critical.

FAQ
What is the package type and dimensions of the W25Q80EWBYIG TR?
The W25Q80EWBYIG TR uses an 8-ball WLCSP (Wafer-Level Chip Scale Package) with package code BY, measuring 2.1 mm × 2.1 mm × 0.5 mm. It complies with JEDEC MO-254 and features bottom-side solder balls for surface-mount assembly. This ultra-compact footprint is validated in Winbond's datasheet Section 3.4 and Figure 1c, and is distinct from SOIC, VSOP, or WSON variants of the W25Q80EW family.
Does the W25Q80EWBYIG TR support Quad SPI and QPI modes, and how is Quad Enable configured?
Yes, the W25Q80EWBYIG TR supports both Quad SPI and QPI modes, but requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to '1'. When QE=0 (factory default), /WP and /HOLD function as hardware control pins; when QE=1, they become IO2 and IO3. The QE bit is written via Write Status Register-2 (31h) instruction and persists through power cycles - confirmed in datasheet Sections 7.1.10 and 6.2.3.
What is the maximum clock frequency and effective data rate for the W25Q80EWBYIG TR in Quad I/O mode?
The W25Q80EWBYIG TR supports up to 104 MHz SPI clock frequency. In Quad I/O mode using Fast Read Quad I/O (EBh), this yields an effective data rate of 416 MB/s (104 MHz × 4 bits per clock). This value is specified in the "Highest Performance Serial Flash" feature list (Section 2) and verified in AC Electrical Characteristics Table 8.6 (page 69) of the datasheet.
How many program-erase cycles and data retention does the W25Q80EWBYIG TR guarantee?
The W25Q80EWBYIG TR guarantees a minimum of 100,000 program-erase cycles per sector and greater than 20 years of data retention at +85°C ambient temperature. These values are explicitly stated in the "Features" section (Section 2) and reinforced in Electrical Characteristics (Section 8.4), applying uniformly across all 256 sectors of the 8 M-bit array.
Does the W25Q80EWBYIG TR include unique identification and security features beyond basic write protection?
Yes, the W25Q80EWBYIG TR includes a factory-programmed 64-bit unique serial number (readable via 4Bh instruction), three 256-byte security registers with OTP locking capability (42h/44h/48h instructions), and JEDEC-standard SFDP register (5Ah) for auto-configurable timing. These features are documented in Sections 2, 7.2.26, and 7.2.28 of the datasheet and are fully implemented in the BY-package variant.
