Product details
Overview
W25Q64JWZPIM from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory supporting Dual/Quad SPI, QPI, and Double Transfer Rate (DTR) read modes. It features uniform 4KB sectors, 100K program-erase cycles, 20-year data retention, and operates with 1mA active / 0.1µA power-down current. Used for code shadowing, XIP execution, and firmware storage in space-constrained embedded systems.
For engineers reviewing the W25Q64JWZPIM datasheet, W25Q64JWZPIM pinout, W25Q64JWZPIM application, or W25Q64JWZPIM equivalent, key selection criteria include Quad I/O timing (133MHz max), JEDEC ID compliance, configurable /HOLD or /RESET function, and hardware write protection via /WP pin - all confirmed for the ZP (8-pad WSON 6×5-mm) package variant.
Technical Context
The W25Q64JWZPIM implements a flexible SPI-compatible interface 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 architecture supports true execute-in-place (XIP) via Quad I/O Fast Read (EBh) and DTR Quad I/O (EDh), achieving up to 66MB/s continuous transfer.
Internal control relies on three status registers with non-volatile configuration bits including Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom protect (TB), and Output Driver Strength (DRV1/DRV0). The /HOLD pin doubles as /RESET in 8-pin packages depending on Status Register-2 settings - a behavior validated for W25Q64JWZPIM's ZP package per datasheet Section 4.6 and Figure 1b.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64M-bit (8MB), organized as 32,768 × 256-byte pages |
| Supply Voltage | 1.7–1.95V - enables low-power operation in battery-backed or energy-sensitive designs |
| Max Clock Frequency | 133MHz for Quad I/O - delivers 532Mbps effective bandwidth (133MHz × 4 lines) |
| Erase Granularity | 4KB sector / 32KB block / 64KB block / full chip - supports fine-grained firmware partitioning |

Pinout & Package
W25Q64JWZPIM uses the 8-pad WSON 6×5-mm package (Package Code ZP), with exposed thermal pad. Pin functions are identical across SOIC, USON, XSON, and WSON 8-pin variants per datasheet Sections 3.2–3.3 and Figure 1b.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; required high→low transition before new instruction acceptance |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes IO1 in Dual/Quad modes - supports fast read and bidirectional command flow |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware lock for status register when QE=0; repurposed as IO2 in Quad mode - requires QE bit set to enable Quad functionality |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; must be low-inductance connection for signal integrity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes IO0 in Dual/Quad modes - carries instructions, addresses, and write data |
| 6 CLK | Serial Clock Input | Edge-triggered timing source; supports SPI Mode 0 and Mode 3; 133MHz max for Quad I/O |
| 7 /HOLD or /RESET (IO3) | Hold or Reset Input / Bidirectional I/O | Pauses ongoing transfers when low (/HOLD); resets internal logic when asserted as /RESET - function selected by Status Register-2 HOLD/RST bit |
| 8 VCC | Power Supply | 1.7–1.95V supply; decoupling capacitor required near pin for stable operation during high-speed reads |
Key Features
| Feature | Design Value |
|---|---|
| DTR Read Support | Enables Double Transfer Rate (0Dh, BDh, EDh) - doubles data throughput per clock cycle without increasing frequency |
| Quad Peripheral Interface (QPI) | Reduces instruction overhead: 2-clock instruction fetch vs. 8-clock SPI - accelerates boot-time code loading |
| Erase/Program Suspend & Resume | Allows background erase or program to pause for higher-priority reads - essential for real-time firmware updates |
| Volatile & Non-Volatile Status Bits | BP, TB, SEC, CMP, QE, DRV, HOLD/RST bits can be set volatile (power-loss reset) or non-volatile - enables runtime reconfiguration with persistence options |
| Hardware Write Protection | /WP pin + status register bits provide layered protection - prevents accidental firmware overwrite during field operation |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
Use Scenario: Storing firmware images and configuration parameters in programmable logic controllers operating in extended temperature environments (-40°C to +85°C).

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 (vs. 1.8V); no DTR support; 80MHz max Quad SPI clock | Requires level-shifting in 1.8V systems; lower bandwidth limits XIP performance in high-speed processors | Select only if existing 3.3V infrastructure prohibits voltage rail redesign |
| S25FL164K0XMFI010 | 1.8V compatible; includes HyperBus interface option; 100MHz Quad SPI; no QPI mode | Lacks QPI instruction compression - increases boot time vs. W25Q64JWZPIM in resource-constrained MCUs | Prefer when HyperBus controller is available and QPI timing optimization is not required |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, W25Q64JWZPIM delivers superior bandwidth (133MHz Quad I/O + DTR), lower active power (1mA), and QPI-based instruction efficiency - making it optimal for compact, battery-aware, and fast-boot embedded systems where 1.8V operation is mandated.

FAQ
What is the package type and pin count of W25Q64JWZPIM?
W25Q64JWZPIM uses an 8-pad WSON (6×5-mm) package with exposed thermal pad (Package Code ZP). It has eight terminals: /CS, DO(IO1), /WP(IO2), GND, DI(IO0), CLK, /HOLD or /RESET(IO3), and VCC - fully documented in datasheet Figure 1b and Section 3.2.
Does W25Q64JWZPIM support Quad SPI and QPI modes simultaneously?
No - W25Q64JWZPIM operates in one interface mode at a time. QPI mode is entered via instruction 38h and exited via FFh; Quad SPI requires QE=1 but remains SPI protocol-compliant. QPI is not active during Quad SPI operation, and both require separate initialization sequences per datasheet Sections 6.1.3–6.1.4.
How is the /HOLD pin function configured on W25Q64JWZPIM?
On W25Q64JWZPIM, pin 7 (/HOLD or /RESET) functions as /HOLD by default. To use it as /RESET, the HOLD/RST bit (bit 7 of Status Register-3) must be set to '1', and QE must be '0'. This configuration is non-volatile and persists across power cycles per datasheet Section 7.1.13.
What is the maximum continuous read speed achievable with W25Q64JWZPIM?
W25Q64JWZPIM achieves up to 66MB/s continuous data transfer using DTR Quad I/O (EDh instruction) at 133MHz clock - equivalent to 532Mbps. This exceeds standard Quad SPI (EBh) by 2× due to double-edge sampling, as specified in datasheet Section 2 and AC Electrical Characteristics Table 9.6.
Can W25Q64JWZPIM be used in systems requiring AEC-Q200 qualification?
W25Q64JWZPIM itself is not AEC-Q200 qualified. However, Winbond offers automotive-grade variants (e.g., W25Q64JWxxIM with 'IM' suffix) that meet AEC-Q200 Grade 3 (-40°C to +85°C) and include enhanced reliability testing. For automotive ADAS use, specify the IM-grade part - W25Q64JWZPIM is industrial-grade only.
