Product details
Overview
W25Q16CVZPIG from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 104 MHz clock rate, 4 KB uniform sector erase, and XIP-capable continuous read mode - deployed in embedded boot code storage, firmware update partitions, and parameter retention in industrial microcontroller systems.
For engineers reviewing the W25Q16CVZPIG datasheet, W25Q16CVZPIG pinout, W25Q16CVZPIG application, or W25Q16CVZPIG equivalent, key selection criteria include Quad Enable bit (QE) configuration for IO2/IO3 remapping, 2.7–3.6 V single-supply operation, JEDEC ID and SFDP register support for auto-configuration, and hardware write protection via /WP and /HOLD pins in standard mode.
Technical Context
The W25Q16CVZPIG implements a SPI command-set architecture with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where Quad mode requires non-volatile QE bit = 1 in Status Register-2. Its internal block diagram includes a 256-byte page buffer, 512 × 4 KB sectors, 32 × 64 KB blocks, and dedicated security registers with OTP locks.
It supports full instruction-level compatibility with JEDEC JESD216 SFDP v1.5 for dynamic parameter discovery, features Erase/Program Suspend & Resume for real-time interrupt handling, and uses high-voltage generators for internal charge-pump programming - enabling >100,000 program/erase cycles and >20-year data retention at -40°C to +85°C.

Pinout & Package
W25Q16CVZPIG is packaged in an 8-pad WSON 6×5 mm (package code ZP), with exposed pad for thermal dissipation and no internal thermal pad connection required. Pin 1 is /CS; pins 2–3–5–7 are bidirectional I/Os (IO1, IO2, IO0, IO3); pin 4 is GND; pin 6 is CLK; pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO/IOx when deasserted; must transition H→L after power-up before first instruction |
| 2 DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes; used for read data and status |
| 3 /WP (IO2) | Write Protect Input / I/O2 | Active-low hardware lock for status register; repurposed as IO2 when QE=1 in Quad mode |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; connects to exposed pad on bottom of WSON package |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes; carries instructions, addresses, and write data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Active-low pause signal during active /CS; repurposed as IO3 when QE=1; allows bus sharing without interrupting ongoing operations |
| 8 VCC | Power Supply | 2.7–3.6 V nominal; decoupling capacitor (≥100 nF) required between VCC and GND near package |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EZN-12G | Same density (16 M-bit), 104 MHz max clock, but lacks Quad Enable bit; IO2/IO3 not available - only Standard/Dual SPI supported | No Quad I/O or XIP acceleration; lower continuous throughput (~26 MB/s max) | Select when Quad SPI is unnecessary and cost sensitivity outweighs performance needs |
| S25FL116K0XMFI011 | 16 M-bit, 85 MHz max clock, supports Quad SPI and SFDP, but uses different status register layout and lacks security registers | No OTP-locked security registers or 64-bit UID; requires modified driver for status bit mapping | Choose for Cypress/Fujitsu ecosystem alignment or where security register functionality is unused |
Compared with W25Q16CVZPIG, MX25L1606EZN-12G omits Quad I/O capability and security registers, limiting XIP performance and secure provisioning; S25FL116K0XMFI011 offers Quad SPI but requires firmware adaptation for status register access and lacks factory-unique identification.

FAQ
What is the package type and footprint of W25Q16CVZPIG?
W25Q16CVZPIG uses an 8-pad WSON 6×5 mm package (code ZP) with exposed thermal pad. It has no leads and mounts directly to PCB pads; recommended land pattern follows JEDEC MO-241AC, with solder mask defined pads and 0.25 mm stencil aperture for reliable reflow.
Does W25Q16CVZPIG support execute-in-place (XIP) operation?
Yes, W25Q16CVZPIG supports true XIP via Continuous Read Mode with ≤8-clock instruction overhead and Fast Read Quad I/O (EBh), enabling direct CPU instruction fetch over Quad SPI. This eliminates RAM copy latency and reduces system memory footprint in MCU-based designs.
How is Quad SPI mode enabled on W25Q16CVZPIG?
Quad SPI mode on W25Q16CVZPIG is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using Write Status Register (01h) instruction. Once set, /WP and /HOLD pins become IO2 and IO3; this configuration persists across power cycles.
What write protection mechanisms does W25Q16CVZPIG provide?
W25Q16CVZPIG provides layered write protection: hardware via active-low /WP pin, software via BP0–BP2, TB, SEC, and CMP bits in Status Register-1, and lock bits SRP0/SRP1 that prevent further status register modification until cleared with Write Enable.
Is W25Q16CVZPIG compatible with JEDEC JESD216 SFDP?
Yes, W25Q16CVZPIG fully complies with JEDEC JESD216 SFDP v1.5. The SFDP register (readable via 5Ah instruction) contains configurable parameters including erase timings, voltage ranges, and Quad Enable bit location - enabling driver auto-configuration without hardcoding.
