Product details
Overview
W25Q64JWBYIM TR from Winbond is a 1.8V, 64M-bit serial NOR flash memory with Dual/Quad SPI, QPI, and DTR read support, organized as 32,768 × 256-byte pages, supporting 4KB/32KB/64KB erase granularity and up to 133MHz Quad I/O clock for 66MB/s continuous transfer. It delivers <0.1µA power-down current and operates across –40°C to +85°C in an 8-pin WLCSP (12-ball, 1.2mm × 1.2mm) package for space-constrained embedded boot code storage.
For engineers reviewing the W25Q64JWBYIM TR datasheet, W25Q64JWBYIM TR pinout, W25Q64JWBYIM TR application, or W25Q64JWBYIM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin behavior in WLCSP, JEDEC ID (EF4017), SFDP register compliance, and hardware write-protection via /WP pin in non-Quad mode.
Technical Context
The W25Q64JWBYIM TR implements a quad I/O SPI interface requiring Status Register-2 QE bit = 1 to repurpose /WP and /HOLD as IO2 and IO3; it supports DTR (Double Transfer Rate) reads using instructions like 0Dh (DTR Fast Read) and EDh (DTR Fast Read Quad I/O), achieving 532MHz effective throughput at 133MHz CLK. Its architecture includes volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP), erase/program suspend/resume, and four 256-byte one-time-programmable security registers.
It features dual-mode reset capability: software reset via 66h+99h instructions, and hardware reset via dedicated /RESET function on IO3 in WLCSP when QE=0 - confirmed by Ball Description WLCSP12 showing C2 as "/HOLD or /RESET (IO3)" with active-low operation and no dedicated /RESET ball in this 12-ball variant.
Key Specifications

Pinout & Package
W25Q64JWBYIM TR uses a 12-ball WLCSP package (Package Code BY), measuring 1.2 mm × 1.2 mm × 0.5 mm, optimized for ultra-compact portable and wearable designs. Pin functions are defined per Ball Description WLCSP12 in the official datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | VCC | 1.8V core supply input - must be decoupled locally to suppress switching noise during high-speed reads |
| C2 | /HOLD or /RESET (IO3) | Configurable active-low control: HOLD pauses ongoing transfers; /RESET forces device initialization - function depends on QE bit state |
| D2 | CLK | Input clock for all SPI/QPI operations - requires clean edge timing; max 133 MHz in Quad I/O mode |
| E2 | DI (IO0) | Primary bidirectional data line - carries instructions/addresses in Standard/Dual/Quad modes; used for input only in Standard SPI |
| B3 | /CS | Chip select - must transition high→low before instruction acceptance; controls output impedance of IO pins |
| C3 | DO (IO1) | Primary bidirectional data line - outputs status/data in Standard SPI; used for I/O in Dual/Quad modes |
| D3 | /WP (IO2) | Hardware write-protect input - active-low; disabled as /WP and repurposed as IO2 when QE=1 in Quad mode |
| E3 | GND | Ground reference - must be low-impedance connection to minimize VCC-GND noise coupling into IO paths |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead: 2-clock instruction fetch vs 8-clock SPI, enabling true XIP with minimal latency |
| Erase/Program Suspend & Resume | Allows background interrupt handling during long erase cycles - critical for real-time OS coexistence |
| JEDEC SFDP Register | Enables automatic host detection of memory geometry, timing, and feature set - eliminates hard-coded driver assumptions |
| Read Command Bypass with Wrap | Eliminates repeated address transmission for sequential access - reduces bus traffic by up to 40% in streaming applications |

FAQ
What is the package type and dimensions of the W25Q64JWBYIM TR?
The W25Q64JWBYIM TR uses a 12-ball WLCSP (Wafer-Level Chip Scale Package) with Package Code BY, measuring 1.2 mm × 1.2 mm × 0.5 mm. This ultra-compact footprint is confirmed in Section 3.6–3.7 and Table 10.7 of the official datasheet, and is distinct from SOIC, USON, or TFBGA variants of the W25Q64JW family.
Does the W25Q64JWBYIM TR support hardware reset via a dedicated /RESET pin?
No - the W25Q64JWBYIM TR does not have a dedicated /RESET pin. In its 12-ball WLCSP package, Ball C2 serves as /HOLD or /RESET (IO3), and hardware reset functionality is only available when QE=0. This is explicitly stated in the WLCSP12 Ball Description and Section 4.6, which notes that /RESET is not provided on 8-pin packages unless configured via IO3.
How is Quad SPI mode enabled on the W25Q64JWBYIM TR?
Quad SPI mode is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) to '1' using the Write Status Register-2 (31h) instruction. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively - a behavior confirmed in Sections 4.2, 4.3, and 4.4 of the datasheet and required for instructions like EBh (Fast Read Quad I/O).
What JEDEC and unique identifiers does the W25Q64JWBYIM TR provide?
The W25Q64JWBYIM TR returns JEDEC ID EF4017 (read via 9Fh instruction), Manufacturer ID EFh, and a factory-programmed 64-bit Unique Serial Number (read via 4Bh). These identifiers are specified in Sections 8.2.30 and 8.2.29 and enable secure device authentication and inventory tracking in production systems.
Can the W25Q64JWBYIM TR be used for Execute-in-Place (XIP) applications?
Yes - the W25Q64JWBYIM TR supports true XIP via Quad SPI and QPI modes, with features including Read Command Bypass, wrap-around burst, and 133MHz clocking. Its 4KB uniform sector size and erase/program suspend/resume allow deterministic latency during code execution, as documented in Sections 2 and 6.1.3–6.1.4 of the datasheet.
