Product details
Overview
W25Q16CVSNJG 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 architecture, 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 W25Q16CVSNJG TR datasheet, W25Q16CVSNJG TR pinout, W25Q16CVSNJG TR application, or W25Q16CVSNJG TR equivalent, key selection considerations include Quad Enable bit (QE) configuration for IO2/IO3 remapping, 2.7–3.6 V single-supply operation, 4 mA active / <1 µA power-down current, and JEDEC-compliant 64-bit unique ID for device traceability.
Technical Context
The W25Q16CVSNJG TR implements a SPI command-driven architecture with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit = 1 in Status Register-2. Its block diagram integrates a 256-byte page buffer, sector/block erase logic (4/32/64 KB), and security registers with OTP locks.
It supports full instruction set compatibility including Fast Read Quad I/O (EBh), Erase/Program Suspend (75h/7Ah), and SFDP register (5Ah) for discoverable timing and feature parameters. Write protection combines hardware (/WP, /HOLD pins) and software (BP2–BP0, TB, SEC, CMP bits) with top/bottom array control and SRP0/SRP1 lock-down.

Pinout & Package
W25Q16CVSNJG TR uses an 8-pin SOIC 150-mil (package code SN) with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC compliant outline. Pin 1 is /CS; Pin 2 is DO (IO1); Pin 3 is /WP (IO2); Pin 4 is GND; Pin 5 is DI (IO0); Pin 6 is CLK; Pin 7 is /HOLD (IO3); Pin 8 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS (Pin 1) | Chip Select input | Active-low enable: high = high-Z outputs and standby current; low = active SPI communication |
| DO / IO1 (Pin 2) | Bidirectional data output/input | Standard SPI output only; Dual/Quad mode: bidirectional I/O for data transfer |
| /WP / IO2 (Pin 3) | Hardware write protect / Quad I/O line | Low-active hardware lock on status register; becomes IO2 when QE=1 (Quad mode) |
| GND (Pin 4) | Ground reference | Primary return path for VCC and all I/O signals; must be low-impedance connection |
| DI / IO0 (Pin 5) | Bidirectional data input/output | Standard SPI input only; Dual/Quad mode: bidirectional I/O for instruction/address/data |
| CLK (Pin 6) | Serial clock input | Edge-triggered timing source for all SPI operations; supports Mode 0 and Mode 3 |
| /HOLD / IO3 (Pin 7) | Hold control / Quad I/O line | Pauses ongoing SPI transaction without deselecting; becomes IO3 when QE=1 (Quad mode) |
| VCC (Pin 8) | Power supply | Single 2.7–3.6 V supply powering core, I/O, and charge pump; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|

| JEDEC ID & Unique Serial Number | 64-bit factory-programmed unique ID accessible via 4Bh instruction; supports device-level traceability |
| Flexible Protection Scheme | Combines hardware (/WP pin) and software (BPx, TB, SEC, CMP, SRP bits) for granular 4 KB–full array lock |
Applications
| Boot Code Storage | Firmware Update Partition |
|---|---|
Use Scenario: Storing primary bootloader and initial firmware image for ARM Cortex-M or RISC-V microcontrollers during cold start. IC Role / Device Role / Timing Role: Non-volatile code storage with XIP-capable Quad SPI interface enabling direct execution without RAM copy. Use Value: Reduces BOM cost and boot latency by eliminating external parallel flash or SRAM pre-load; leverages 104 MHz Quad SPI for sub-100 ms boot time. | Use Scenario: Dedicated partition for over-the-air (OTA) firmware updates in networked industrial gateways. IC Role / Device Role / Timing Role: Field-upgradable persistent storage with atomic sector erase and suspend/resume for safe interrupt handling. Use Value: Enables robust dual-bank update schemes using 4 KB sector granularity and Erase/Program Suspend (75h/7Ah) to avoid corruption during power loss. |
| Parameter & Calibration Data | Secure Key Storage |
Use Scenario: Retaining sensor calibration coefficients, motor tuning values, and user preferences across power cycles in PLC modules. IC Role / Device Role / Timing Role: Low-power, long-retention non-volatile storage accessed infrequently via Standard SPI. Use Value: Guarantees ≥20-year data retention and >100k write cycles - sufficient for lifetime field recalibration without wear leveling. | Use Scenario: Storing cryptographic keys and secure boot certificates in medical device controllers requiring tamper resistance. IC Role / Device Role / Timing Role: Hardware-isolated OTP-locked security registers (3×256 bytes) with lock-down via SRP bits. Use Value: Prevents unauthorized read/write of keys even if main array is compromised; meets IEC 62304 Class C security requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory 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 and SFDP register; uses legacy status register layout | No native Quad SPI support; limited continuous read optimization; no unique ID or security registers | Choose for legacy designs requiring pin-to-pin replacement without Quad mode or security features |
| S25FL116K0XMFI011 | 16 M-bit, 85 MHz max clock, supports Quad SPI and SFDP, but uses different QE implementation (volatile vs. non-volatile) and lacks OTP security registers | Lower throughput than W25Q16CVSNJG TR; no factory-programmed unique ID; security relies on software-only locks | Prefer when migrating from Cypress ecosystem and needing SFDP compatibility without OTP key storage |
Compared with MX25L1606EZN-12G and S25FL116K0XMFI011, the W25Q16CVSNJG TR delivers higher sustained bandwidth (416 MHz Quad I/O), factory-traceable identity (64-bit UID), and hardware-enforced security (OTP-locked registers), making it optimal for next-generation secure boot and OTA update architectures.

FAQ
What is the package type and lead count of W25Q16CVSNJG TR?
W25Q16CVSNJG TR uses an 8-pin SOIC 150-mil (package code SN) with gull-wing leads and 1.27 mm pitch. It is JEDEC MS-012AC compliant and measures 3.9 mm × 4.9 mm. This package is distinct from WSON, TFBGA, or PDIP variants of the W25Q16CV family and is specified in Winbond's official ordering table for the "SN" suffix.
Does W25Q16CVSNJG TR support Quad SPI mode out of the box?
No - W25Q16CVSNJG TR requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., EBh, 6Bh) will function. By default, QE = 0; users must issue Write Status Register (01h) with appropriate byte value to enable IO2 (/WP) and IO3 (/HOLD) as data lines. Failure to configure QE results in unrecognized commands or standard SPI fallback.
What is the maximum clock frequency supported by W25Q16CVSNJG TR in Quad I/O mode?
W25Q16CVSNJG TR supports up to 104 MHz on the CLK pin in Quad I/O mode, delivering an effective data rate of 416 Mbps (104 MHz × 4 lines). This is confirmed in Section 2 ("Features") and Section 8.7 ("AC Electrical Characteristics") of the datasheet, with timing validated under VCC = 2.7–3.6 V and TA = –40°C to +85°C.
How many program/erase cycles does W25Q16CVSNJG TR guarantee?
W25Q16CVSNJG TR guarantees ≥100,000 program/erase cycles per sector, as stated in Section 2 ("Features") and Section 8.5 ("DC Electrical Characteristics"). This endurance applies uniformly across all 512 sectors and is validated under industrial temperature conditions with standard erase algorithms (20h, 52h, D8h).
Is the 64-bit unique ID in W25Q16CVSNJG TR factory-programmed and readable?
Yes - W25Q16CVSNJG TR includes a factory-programmed, unalterable 64-bit unique serial number accessible via the Read Unique ID Number instruction (4Bh). This ID is laser-marked during wafer sort and verified per unit; it enables secure device authentication, firmware binding, and supply chain traceability without requiring user programming.
