Winbond Electronics Corporation W25Q16CVZPJP TR

Overview

W25Q16CVZPJP TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 104 MHz clock capability, 4 KB uniform sector erase architecture, and hardware write protection via /WP and /HOLD pins - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.

For engineers reviewing the W25Q16CVZPJP TR datasheet, W25Q16CVZPJP TR pinout, W25Q16CVZPJP TR application, or W25Q16CVZPJP TR equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, 2.7–3.6 V single-supply operation, 4 mA active current, -40°C to +85°C industrial temperature range, and 8-pad WSON 6×5-mm (ZP) package compatibility.

Technical Context

The W25Q16CVZPJP TR implements a SPI command set compliant with JEDEC JESD216 SFDP v1.5, enabling auto-discovery of memory geometry and timing parameters. Its dual- and quad-I/O modes rely on bidirectional IO0–IO3 pins activated only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set - disabling /WP and /HOLD functions during Quad SPI operation.

Internal architecture includes an 8,192-page (256-byte/page) array organized into 512 × 4 KB sectors and 32 × 64 KB blocks, supporting sector/block/chip erase, page program, and erase/program suspend/resume - all managed by dedicated command logic and high-voltage generators without external components.

Key Specifications

Pinout & Package

W25Q16CVZPJP TR uses the 8-pad WSON 6×5-mm package (package code ZP), with exposed thermal pad (non-electrical). Pin 1 is marked by a dot or beveled corner; pin numbering follows counter-clockwise orientation from top-left when viewed from top side.

FAQ

What is the package type and footprint of W25Q16CVZPJP TR?

W25Q16CVZPJP TR uses the 8-pad WSON 6×5-mm package (ZP code) with exposed thermal pad. It has a 0.5 mm pitch, 2.5 mm × 3.0 mm body size, and JEDEC-standard land pattern requiring solder mask defined pads and stencil-applied solder paste. The pinout matches SOIC/VSOP variants electrically but differs mechanically - PCB layout must follow Winbond's ZP footprint drawing (DS-W25Q16CV-011).

Does W25Q16CVZPJP TR support execute-in-place (XIP) operation?

Yes, W25Q16CVZPJP TR supports true XIP via Continuous Read Mode with ≤8-clock instruction overhead per 24-bit address access. When configured for Quad SPI (QE=1) and used with compatible MCU QSPI peripherals (e.g., STM32L4/L5, NXP i.MX RT), it enables direct code execution without RAM loading - verified in Winbond Application Note AN2017-03.

How is hardware write protection implemented on W25Q16CVZPJP TR?

W25Q16CVZPJP TR provides dual-layer hardware write protection: (1) the /WP pin disables status register writes when low (active), and (2) Block Protect (BP2–BP0), Top/Bottom (TB), and Sector Protect (SEC) bits in Status Register-1 define protected memory regions. Protection persists through power cycles and requires /WP low + correct SR bits to activate - detailed in Section 6.2 of the datasheet.

What is the function of the /HOLD pin on W25Q16CVZPJP TR?

The /HOLD pin on W25Q16CVZPJP TR pauses ongoing SPI transactions (reads, writes, erases) while /CS remains low. When asserted low, DO goes high-impedance and DI/CLK inputs are ignored - allowing shared SPI bus arbitration. In Quad SPI mode (QE=1), /HOLD becomes IO3 and loses hold functionality, as documented in Section 4.4 and Figure 1b of the datasheet.

Can W25Q16CVZPJP TR be used with standard SPI controllers that do not support Dual or Quad modes?

Yes, W25Q16CVZPJP TR is fully backward-compatible with standard SPI controllers. It defaults to Standard SPI (DI/DO only) at power-up; Dual/Quad modes require explicit instruction (e.g., Write Status Register to set QE bit) and are disabled unless configured. All Standard SPI instructions (03h Read Data, 02h Page Program, etc.) operate identically across modes - confirmed in Table 7.2.10–7.2.21.
