Product details
Overview
W25Q256JVCIQ TR from Winbond is a 256M-bit (32MB) serial NOR flash memory supporting Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock frequency, 4KB uniform sector architecture, and hardware write protection via /WP and /HOLD pins. It operates from 2.7V–3.6V, supports XIP execution, and is used for code storage, firmware boot, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q256JVCIQ TR datasheet, W25Q256JVCIQ TR pinout, W25Q256JVCIQ TR application, or W25Q256JVCIQ TR equivalent, key selection factors include 4-byte addressing support, JEDEC SFDP compliance, 100K program-erase cycles per sector, 20-year data retention, and package-specific /RESET availability in SOIC-16 and TFBGA variants.
Technical Context
The W25Q256JVCIQ TR implements a flexible SPI interface with mode-selectable operation: Standard SPI uses DI/DO unidirectionally; Dual SPI repurposes DI/DO as bidirectional IO0/IO1; Quad SPI further enables IO2 (/WP) and IO3 (/HOLD) after setting the non-volatile QE bit in Status Register-2. Addressing supports both 3-byte (with Extended Address Register) and 4-byte modes, enabling full 256M-bit address space access without external logic.
Its internal architecture includes 8,192 erasable 4KB sectors and 512 erasable 64KB blocks, with independent suspend/resume for erase/program operations. Security features include three 256-byte OTP-locked security registers, 64-bit unique ID, top/bottom/complement block protection, and volatile/non-volatile status register bits for granular memory locking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L25645GMI-10G | Same density (256Mb), 3.3V, but max Quad SPI clock 104 MHz; lacks 4-byte address mode in base config | Requires external address translation for full 256Mb access; lower throughput limits XIP performance | Select if legacy SPI controller lacks 4-byte mode support and 104 MHz suffices |
| S25FL256SAGMFI010 | 256Mb, 3.0V–3.6V, supports 133 MHz Quad SPI and 4-byte addressing; includes on-die ECC | On-die ECC improves bit-error resilience in high-temp or radiation-prone environments | Prefer for mission-critical applications where data integrity exceeds Winbond's spec |
Compared with MX25L25645GMI-10G and S25FL256SAGMFI010, the W25Q256JVCIQ TR offers native 4-byte addressing without configuration overhead and higher sustained Quad I/O bandwidth, making it optimal for fast-boot and XIP-critical designs where ECC is managed externally.

FAQ
What is the difference between W25Q256JVCIQ TR and W25Q256JVSIM?
The W25Q256JVCIQ TR uses an 8-pad WSON 8×6-mm package (Code E) without a dedicated /RESET pin, whereas W25Q256JVSIM is in a 16-pin SOIC 300-mil package (Code F) with a separate /RESET pin. Both share identical electrical specs and instruction sets, but the SOIC variant supports hardware reset independent of /HOLD functionality - critical for systems requiring deterministic recovery from lockup conditions. The W25Q256JVCIQ TR remains fully functional in reset-free designs using software reset (66h+99h).
Does W25Q256JVCIQ TR support Quad SPI out of the box?
No - Quad SPI operation requires enabling the Quad Enable (QE) bit in Status Register-2 (SR2) via Write Status Register-2 (31h) instruction. Until QE=1, /WP and /HOLD remain dedicated hardware control pins. Once set, those pins become IO2 and IO3, enabling true 4-line data transfer. The QE bit is non-volatile, so configuration persists across power cycles unless explicitly cleared.
Can W25Q256JVCIQ TR be used in 4-byte address mode without external logic?
Yes - the W25Q256JVCIQ TR natively supports 4-byte addressing via Enter 4-Byte Address Mode (B7h) and Exit 4-Byte Address Mode (E9h) instructions. No external address latches or glue logic are needed. The ADP bit in Status Register-3 determines power-up default mode, and the Extended Address Register (C8h/C5h) provides backward compatibility in 3-byte mode for partial addressing.
How many program-erase cycles does W25Q256JVCIQ TR guarantee per sector?
The W25Q256JVCIQ TR guarantees a minimum of 100,000 program-erase cycles per 4KB sector, validated per JEDEC JESD22-A117 standard. This endurance rating applies across the full operating temperature range (−40°C to +85°C) and voltage range (2.7V–3.6V), ensuring reliable field operation in demanding embedded applications.
Is the 64-bit unique ID in W25Q256JVCIQ TR readable over SPI?
Yes - the 64-bit unique serial number is accessed via the Read Unique ID Number instruction (4Bh), which returns 8 bytes of factory-programmed, globally unique data. This ID is one-time programmable and cannot be altered, making it suitable for device authentication, secure boot binding, or automated inventory tracking in production lines.
