Product details
Overview
W25Q64JWZPIM TR from Winbond is a 1.8V, 64M-bit serial NOR flash memory with Dual/Quad SPI, QPI, and Double Transfer Rate (DTR) support. It features 32,768 × 256-byte pages, 4KB uniform sector erase, 133MHz Quad I/O clock capability, and hardware write protection via /WP and /HOLD pins. It is used for code execution directly from flash (XIP), firmware storage, and boot code in space-constrained embedded systems.
For engineers reviewing the W25Q64JWZPIM TR datasheet, W25Q64JWZPIM TR pinout, W25Q64JWZPIM TR application, or W25Q64JWZPIM TR equivalent, this page delivers verified package mapping (8-pin WSON 6×5-mm, ZP code), confirmed pin functions including IO0–IO3 remapping under QE=1, JEDEC ID compliance, SFDP register support, and real-world timing behavior for DTR Fast Read (0Dh/EDh) and QPI mode entry (38h).
Technical Context
The W25Q64JWZPIM TR implements a quad-I/O SPI interface with non-volatile Quad Enable (QE) bit in Status Register-2; when QE=1, /WP and /HOLD become IO2 and IO3, enabling true 4-line bidirectional data transfer. It supports SPI Mode 0/3, QPI mode (entered via 38h instruction), and DTR read operations requiring precise setup/hold timing on CLK relative to data edges.
Its architecture includes volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP, SUS, LB1–LB3, DRV0/DRV1, HOLD/RST), programmable output drive strength, and Erase/Program Suspend & Resume functionality - all accessible via standardized SPI instructions like 75h/7Ah and supported across all package variants.

Pinout & Package
W25Q64JWZPIM TR uses the 8-pin WSON 6×5-mm package (JEDEC MO-252, Winbond package code ZP), with exposed thermal pad. Pin 1 is marked by dot; pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD or /RESET (IO3), pin 8 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select Input | Active-low enable: high = high-Z outputs and standby current (~0.1 µA); must transition high→low after power-up before first command |
| DO / IO1 (Pin 2) | Bidirectional Data Line | Output in Standard SPI; input/output in Dual/Quad SPI/QPI; requires QE=1 for Quad I/O use |
| /WP / IO2 (Pin 3) | Hardware Write Protect / Data Line | Active-low hardware lock for status register; becomes IO2 when QE=1 - disables /WP function |
| GND (Pin 4) | Ground Reference | Primary return path for VCC and I/O signals; must be low-impedance for stable DTR timing |
| DI / IO0 (Pin 5) | Bidirectional Data Line | Input in Standard SPI; input/output in Dual/Quad SPI/QPI; required for all instruction transfers |
| CLK (Pin 6) | Serial Clock Input | Edge-triggered timing reference; supports Mode 0/3; DTR mode requires strict tSU/tH relative to data valid windows |
| /HOLD or /RESET / IO3 (Pin 7) | Hold Control or Reset Input / Data Line | Pauses ongoing read/write when low; becomes IO3 when QE=1 - disables /HOLD function |
| VCC (Pin 8) | Power Supply | 1.7–1.95 V supply; decoupling capacitor (≥1 µF) required near pin for stable DTR and QPI operation |
Key Features
| Feature | Design Value |
|---|---|
| DTR Read Support (0Dh/EDh) | Enables double-data-rate sampling on CLK edges - doubles effective throughput without increasing clock frequency |
| QPI Mode (38h) | Reduces instruction overhead: 8-bit opcodes transferred in 2 clocks instead of 8 - accelerates command latency in XIP applications |
| Erase/Program Suspend (75h/7Ah) | Allows background erase or program to pause and service higher-priority reads - critical for real-time firmware updates |
| Individual Block Lock (36h/39h) | Per-sector hardware lock via security registers - prevents accidental overwrite of bootloader or calibration data |
| Output Drive Strength Control (DRV0/DRV1) | Configurable drive level (weak/medium/strong) - optimizes signal integrity on long traces or high-capacitance buses |
| SFDP Register (5Ah) | Standardized, read-only parameter table - enables automatic host configuration without hard-coded timing constants |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |

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 |
|---|---|---|---|
| MX25L6433FZNI-10G | 3.3V supply, no DTR support, 104MHz max Quad SPI clock | Lacks DTR and QPI modes; lower bandwidth limits XIP performance in latency-sensitive designs | Choose only if system operates at 3.3V and does not require >52 MB/s read throughput or DTR timing margin |
| S25FL164K0XMFI011 | 1.8V supply, supports DTR but no QPI; 80MHz max Quad SPI clock | Missing QPI instruction compression - increases command latency and CPU overhead during frequent small reads | Select when QPI mode is unnecessary and design prioritizes Cypress's long-term lifecycle assurance over peak bandwidth |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI011, the W25Q64JWZPIM TR uniquely combines 1.8V operation, 133MHz Quad I/O, DTR, and QPI - delivering the highest deterministic read bandwidth and lowest instruction latency among pin-compatible 64M-bit serial NOR flash devices in WSON-8 packaging.

FAQ
What is the package type and footprint for W25Q64JWZPIM TR?
W25Q64JWZPIM TR uses the 8-pin WSON 6×5-mm package (JEDEC MO-252, Winbond code ZP) with an exposed thermal pad. Its footprint matches standard WSON-8 land patterns; pin 1 is marked by a dot, and the package has 0.5 mm pitch. This variant is distinct from SOIC-8 (SS), USON-8 (UU), or TFBGA-24 (TB) versions of the same W25Q64JW family.
Does W25Q64JWZPIM TR support Quad SPI and QPI modes simultaneously?
No - W25Q64JWZPIM TR supports either Quad SPI or QPI mode, but not both concurrently. QPI mode is entered explicitly via the 38h instruction and exited using FFh; in QPI mode, all commands (including reads and writes) use 4-bit-wide transfers on IO0–IO3. Quad SPI remains active outside QPI mode and requires QE=1 in Status Register-2.
How does the /WP pin behave when Quad Enable (QE) is set on W25Q64JWZPIM TR?
When QE=1 in Status Register-2, the /WP pin (Pin 3) of W25Q64JWZPIM TR is reassigned as IO2 and loses its hardware write-protect function. Hardware protection must then rely solely on status register bits (BP2–BP0, TB, SEC) and security register locks - software-configured, not pin-driven.
What is the purpose of the SFDP register in W25Q64JWZPIM TR?
The SFDP (Serial Flash Discoverable Parameters) register (accessed via 5Ah instruction) provides a standardized, read-only table of timing parameters, erase block sizes, and feature flags. It allows host controllers to auto-configure read latencies and command sets without hardcoding values - improving interoperability across different flash vendors and reducing qualification effort for W25Q64JWZPIM TR integration.
Can W25Q64JWZPIM TR be used for Execute-in-Place (XIP) applications?
Yes - W25Q64JWZPIM TR supports true XIP via Quad SPI and QPI interfaces, with 133MHz clock and DTR read instructions (0Dh/EDh) enabling high-throughput, low-latency code fetch. Its uniform 4KB sector layout and Erase/Program Suspend (75h/7Ah) allow safe runtime firmware updates without halting execution - essential for real-time XIP deployments.
