Winbond Electronics Corporation W25Q16BVZPIG TR

Overview

W25Q16BVZPIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory supporting Standard, Dual, and Quad SPI interfaces with 4 KB uniform sectors, 104 MHz clock operation, and 50 MB/s continuous read throughput. It serves as non-volatile code storage for microcontroller boot code, firmware updates, and configuration data in space-constrained embedded systems.

For engineers reviewing the W25Q16BVZPIG TR datasheet, W25Q16BVZPIG TR pinout, W25Q16BVZPIG TR application, or W25Q16BVZPIG TR equivalent, key selection considerations include Quad SPI XIP capability, hardware write protection via /WP and /HOLD pins, JEDEC ID and 64-bit unique serial number support, and compatibility with -40°C to +85°C industrial temperature requirements.

Technical Context

The W25Q16BVZPIG TR implements a SPI-compatible command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD only after setting the non-volatile Quad Enable (QE) bit in Status Register-2. Its block diagram integrates a 256-byte page buffer, column/row decode logic, high-voltage generators, and dual status registers for flexible erase/write control.

It supports four erase granularities - 4 KB sector, 32 KB block, 64 KB block, and full chip - enabling precise data management in mixed-code-and-parameter applications. The device uses SPI bus Modes 0 and 3, requires /CS low-to-high transition before instruction acceptance, and enforces tPUW power-up write inhibit delay to prevent spurious writes during voltage ramp-up.

FAQ

What is the package type and footprint of the W25Q16BVZPIG TR?

The W25Q16BVZPIG TR uses an 8-pin WSON 6×5 mm package (code ZP) with an exposed thermal pad. It has the same pinout as the SOIC-8 variants but occupies ~40% less PCB area and offers improved thermal dissipation. The footprint matches JEDEC MO-241AC standards and is compatible with standard reflow profiles for lead-free assembly.

Does the W25Q16BVZPIG TR support execute-in-place (XIP) operation?

Yes, the W25Q16BVZPIG TR supports true XIP via its Continuous Read Mode, which reduces instruction overhead to as few as 8 clock cycles per 24-bit address. When used with Quad SPI Fast Read Quad I/O (EBh) at 104 MHz, it delivers up to 416 Mbps effective bandwidth - sufficient for direct code execution in ARM Cortex-M and RISC-V microcontrollers without local RAM buffering.

How does hardware write protection work on the W25Q16BVZPIG TR?

The W25Q16BVZPIG TR implements hardware write protection using the /WP pin (Pin 3), which - when held low - prevents writes to the Status Register regardless of software commands. This function is active in Standard and Dual SPI modes. In Quad SPI mode (QE=1), /WP becomes IO2 and hardware protection is disabled; software protection via SRP/BP bits remains fully functional.

What is the purpose of the /HOLD pin on the W25Q16BVZPIG TR?

The /HOLD pin (Pin 7) pauses ongoing SPI transactions while /CS remains low, placing DO in high-impedance and ignoring DI and CLK edges. This enables bus sharing among multiple SPI slaves without interrupting internal operations like page programming. /HOLD is inactive in Quad SPI mode, where Pin 7 functions as IO3.

Can the W25Q16BVZPIG TR be used in automotive applications?

Yes, the W25Q16BVZPIG TR is rated for -40°C to +85°C operation and meets industrial reliability standards, including 100,000 program/erase cycles and 20+ year data retention. While not AEC-Q100 qualified, it is widely deployed in non-safety-critical automotive subsystems such as infotainment, telematics, and body control modules where extended temperature and long-term stability are required.
