Winbond Electronics Corporation W25Q16JVXGIQ TR

Overview

W25Q16JVXGIQ TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory with quad SPI interface, organized as 8,192 × 256-byte pages, supporting 4 KB sector, 32 KB block, 64 KB block and chip erase. It operates from 2.7 V to 3.6 V, delivers up to 133 MHz clock rate (532 MHz equivalent in Quad I/O mode), and features hardware /WP and /HOLD pins for write protection and suspend control - used in embedded boot code storage and firmware update modules.

For engineers reviewing the W25Q16JVXGIQ TR datasheet, W25Q16JVXGIQ TR pinout, W25Q16JVXGIQ TR application, or W25Q16JVXGIQ TR equivalent, key selection criteria include Quad SPI XIP capability, 100K program-erase cycle endurance, -40°C to +85°C industrial temperature grade, JEDEC ID/SFDP register support, and 8-pin USON 2×3-mm package compatibility with space-constrained PCB layouts.

Technical Context

The W25Q16JVXGIQ TR implements a standard SPI bus (Mode 0/3) with dual and quad I/O extensions enabled via non-volatile QE bit in Status Register-2. Its architecture supports true execute-in-place (XIP) via continuous read with wrap modes (8/16/32/64-byte), requiring only 8 clocks to address memory.

It integrates three status registers (SR1–SR3) with volatile/non-volatile bits for block protection (BP2–BP0), top/bottom lock (TB), security register lock (LB3–LB1), and quad enable (QE). The /HOLD pin functions as IO3 in Quad mode, while /WP becomes IO2 - both pins revert to hardware protection roles in Standard/Dual SPI operation.

FAQ

What is the package type and lead count of W25Q16JVXGIQ TR?

W25Q16JVXGIQ TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm × 0.6 mm, with wettable flank leads for reliable automated optical inspection and solder joint quality verification. This compact footprint supports high-density PCB layouts in space-constrained applications such as wearables and smart sensors.

Does W25Q16JVXGIQ TR support Quad SPI mode, and how is it enabled?

Yes, W25Q16JVXGIQ TR supports Quad SPI mode via the non-volatile Quad Enable (QE) bit in Status Register-2. When QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively, enabling four-line data transfer. This configuration must be set explicitly using Write Status Register-2 (31h) and verified with Read Status Register-2 (35h) before issuing Quad I/O instructions like EBh.

What is the maximum clock frequency supported by W25Q16JVXGIQ TR in different SPI modes?

W25Q16JVXGIQ TR supports up to 133 MHz in Standard and Dual SPI modes, delivering 133 MB/s and 266 MB/s effective throughput respectively. In Quad SPI mode using Fast Read Quad I/O (EBh), it achieves 532 MB/s equivalent bandwidth. These rates are specified under VCC = 3.0 V to 3.6 V and TA = -40°C to +85°C conditions per the official datasheet.

How does hardware write protection work on W25Q16JVXGIQ TR?

Hardware write protection on W25Q16JVXGIQ TR is implemented via the active-low /WP pin, which - when held low - prevents writes to the Status Register regardless of software commands. This function is active only when the Quad Enable (QE) bit is cleared (QE=0); when QE=1, /WP becomes IO2 and hardware protection is disabled unless WPS=0 is configured in Status Register-3 to re-enable BP/TB/CMP-based locking.

Is W25Q16JVXGIQ TR suitable for execute-in-place (XIP) applications?

Yes, W25Q16JVXGIQ TR is explicitly designed for XIP operation, supporting continuous read with 8/16/32/64-byte wrap modes and requiring only 8 clock cycles to address memory. Its 133 MHz Quad SPI clock and 532 MB/s effective bandwidth enable deterministic code fetch latency, making W25Q16JVXGIQ TR ideal for ARM Cortex-M and RISC-V microcontrollers running bootloaders directly from flash.
