Winbond Electronics Corporation W25Q80BWBYIG TR

Overview

W25Q80BWBYIG TR from Winbond is an 8M-bit (1MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 1.65–1.95V single-supply operation, 80MHz clock rate, and 4KB uniform sector architecture. It delivers 40MB/s continuous read throughput and supports execute-in-place (XIP) for code storage in space-constrained embedded systems.

For engineers reviewing the W25Q80BWBYIG TR datasheet, W25Q80BWBYIG TR pinout, W25Q80BWBYIG TR application, or W25Q80BWBYIG TR equivalent, key selection considerations include Quad SPI enable (QE bit), /WP and /HOLD dual-role I/O mapping, 4KB sector granularity for firmware parameter storage, and WLCSP-8 (BY) package compatibility with high-density PCB layouts.

Technical Context

The W25Q80BWBYIG TR implements a SPI command set compliant with JEDEC JESD216, supporting Standard (4-wire), Dual (2 I/O lines), and Quad (4 I/O lines) modes via configurable IO0–IO3 pins. Its status register includes non-volatile Quad Enable (QE) bit enabling IO2 (/WP) and IO3 (/HOLD) for Quad I/O operations.

It features hardware write protection via active-low /WP pin (when QE=0), programmable sector/block lock bits (BP2–BP0, TB, SEC), and 64-bit unique serial number. Erase granularity spans 4KB sectors (256 total), 32KB blocks (32), and 64KB blocks (16), with suspend/resume capability for background erase/program cycles.

Key Specifications

Pinout & Package

FAQ

What is the package type and footprint of the W25Q80BWBYIG TR?

The W25Q80BWBYIG TR uses an 8-ball WLCSP (WLBGA) package with 0.4 mm pitch and 2.1 × 2.1 mm body size, designated by Winbond package code "BY". This ultra-compact footprint supports fine-pitch routing and thermal dissipation in space-constrained PCBs, and is fully compatible with standard reflow profiles for lead-free assembly. The ball map matches the functional pinout defined in Section 3.4 of the official datasheet.

Does the W25Q80BWBYIG TR support Quad SPI mode, and how is it enabled?

Yes, the W25Q80BWBYIG TR supports Quad SPI mode using instructions such as Fast Read Quad I/O (EBh). Activation requires setting the non-volatile Quad Enable (QE) bit in Status Register-2 via Write Status Register (01h) instruction. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively, enabling 4-line bidirectional communication and 320MHz-equivalent data rates.

What is the minimum and maximum supply voltage for reliable operation of the W25Q80BWBYIG TR?

The W25Q80BWBYIG TR operates reliably within a supply voltage range of 1.65 V to 1.95 V. Operation below 1.65 V may cause undefined behavior or failure to accept commands; above 1.95 V risks permanent damage. The device incorporates internal voltage monitoring and resets automatically if VCC falls below the write-inhibit threshold (VWI), ensuring data integrity during brown-out conditions.

How many erase cycles can the W25Q80BWBYIG TR endure, and what is its data retention specification?

The W25Q80BWBYIG TR guarantees a minimum of 100,000 program/erase cycles per sector and 20 years of data retention at +25°C. Retention is specified down to −40°C and up to +85°C, with derating applied per JEDEC standards. These values are validated per Winbond's qualification testing and apply uniformly across all 256 sectors of the 8M-bit array.

Can the W25Q80BWBYIG TR be used for execute-in-place (XIP) applications, and what feature enables this?

Yes, the W25Q80BWBYIG TR supports true execute-in-place (XIP) operation via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles for address setup. Combined with Quad SPI read speeds up to 320MHz-equivalent, this enables deterministic, low-latency code fetch directly from flash - eliminating the need for full RAM shadowing in resource-constrained microcontrollers.
