Winbond Electronics Corporation W25R128JVPIQ TR

Overview

W25R128JVPIQ TR from Winbond is a 3V, 128M-bit (16MB) serial NOR flash memory supporting Dual/Quad SPI and Replay Protection Monotonic Counter (RPMC) security. It delivers up to 133MHz clock rate, 532MHz equivalent Quad I/O throughput, 4KB uniform sector architecture, and operates from -40°C to +85°C with 4mA active and <1µA power-down current. It is used for XIP code execution, firmware storage, and secure boot in resource-constrained embedded systems.

For engineers reviewing the W25R128JVPIQ TR datasheet, W25R128JVPIQ TR pinout, W25R128JVPIQ TR application, or W25R128JVPIQ TR equivalent, key selection considerations include Quad SPI timing compliance, RPMC cryptographic support, individual block lock granularity, 2.7–3.6V supply tolerance, and WSON 8-pad 6×5-mm package compatibility with high-density PCB layouts.

Technical Context

The W25R128JVPIQ TR implements a standard SPI interface with configurable Dual/Quad I/O modes using shared bidirectional IO0–IO3 pins, supporting SPI modes 0 and 3. Its internal architecture includes three status registers (SR1–SR3) with volatile/non-volatile bits for write protection, quad enable (QE), output driver strength (DRV1/DRV0), and security register locks (LB3–LB1).

RPMC functionality relies on HMAC-SHA-256 authentication with four 32-bit monotonic counters, accessed via dedicated 9Bh-based commands (e.g., 9Bh+00h for root key write). Security operations require prior enabling of OTP-locked security registers and are independent of standard erase/program cycles.

Key Specifications

FAQ

What is the package type and footprint of W25R128JVPIQ TR?

W25R128JVPIQ TR uses an 8-pad WSON 6×5-mm package (Package Code P) with wettable flanks. Its footprint matches JEDEC MO-241AC standards, featuring 0.5 mm pitch, exposed thermal pad, and symmetric pinout identical to other Winbond WSON-8 variants like W25Q128JV. The package is RoHS-compliant and qualified for reflow per J-STD-020.

Does W25R128JVPIQ TR support Quad SPI mode out of the box?

W25R128JVPIQ TR supports Quad SPI but requires explicit configuration: the Quad Enable (QE) bit in Status Register-1 must be set via Write Status Register-1 (01h) instruction. Factory default is QE = 0, so Standard/Dual SPI only until enabled. Once set, QE persists across power cycles unless cleared by a write to SR1.

How does the Replay Protection Monotonic Counter (RPMC) work in W25R128JVPIQ TR?

W25R128JVPIQ TR implements four independent 32-bit monotonic counters addressed via 8-bit Counter_Address. Each counter increments on successful HMAC-SHA-256-verified read/write operations. The RPMC engine uses a secret root key (written via 9Bh+00h) and HMAC-SHA-256 to validate counter state, preventing replay, rollback, or counter spoofing attacks during secure boot or firmware validation.

What write protection mechanisms are available on W25R128JVPIQ TR?

W25R128JVPIQ TR offers layered write protection: software-controlled BP/TB/SEC bits in status registers, hardware /WP pin (shared with IO0), Individual Block Lock bits (254 blocks + 32 sectors), Power-down instruction lock, and OTP-locked security registers. The WPS bit selects between block-protect (WPS=0) and individual-lock (WPS=1) schemes.

Can W25R128JVPIQ TR be used for Execute-in-Place (XIP) applications?

Yes, W25R128JVPIQ TR supports XIP via Fast Read Quad I/O (EBh) and Word Read Quad I/O (E7h) instructions. With 133 MHz CLK and Quad mode, it delivers up to 532 Mbps effective bandwidth-sufficient for real-time code execution from flash on Cortex-M7/M33 and RISC-V cores without intermediate RAM loading.
