Product details
Overview
W25Q16JLSSIG TR from Winbond is a 16 M-bit (2 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 104 MHz clock rate, 4 KB uniform sector erase granularity, and 2.3–3.6 V single-supply operation - deployed for code execution (XIP), firmware storage, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q16JLSSIG TR datasheet, W25Q16JLSSIG TR pinout, W25Q16JLSSIG TR application, or W25Q16JLSSIG TR equivalent, this page delivers verified electrical specs, SOIC-8 (208-mil) package mapping, Quad Enable (QE) configuration impact on /WP and /HOLD pins, JEDEC ID and SFDP register support, and real-world XIP and firmware update use cases.
Technical Context
The W25Q16JLSSIG 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 Quad mode requires non-volatile QE bit = 1 in Status Register-2. Its architecture supports concurrent program/erase suspend-resume, 64-bit unique ID, and SFDP register for discoverable timing and feature parameters.
It features dual-function pins (/WP and /HOLD) that become IO2 and IO3 in Quad mode, and includes volatile/non-volatile status register bits for flexible protection (BP2–BP0, TB, SEC, CMP, SRP), power-down current <1 µA (typ.), and 100K program-erase cycles per sector with >20-year data retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L1606EM2I-12G | Same density (16 M-bit), 3.3 V, SOIC-8; supports standard/Dual SPI only - no Quad I/O or QE bit | Lacks Quad SPI, SFDP, and suspend/resume; lower max clock (86 MHz); no 64-bit UID | Select when Quad performance and advanced features are unnecessary; lower cost for legacy SPI-only designs |
| S25FL116K0XMFI041 | 16 M-bit, 3.0 V min, SOIC-8; supports Quad SPI (QPI mode), but uses different command set and QE implementation | Requires QPI entry sequence; lacks SFDP register; no dedicated /HOLD or /RESET pin multiplexing | Choose for Cypress/Fujitsu ecosystem compatibility; verify command mapping and initialization flow before migration |
Compared with MX25L1606EM2I-12G and S25FL116K0XMFI041, the W25Q16JLSSIG TR delivers higher throughput (104 MHz Quad), standardized SFDP auto-configuration, suspend/resume for real-time systems, and factory-unique ID - making it optimal for new XIP, OTA, and secure-edge designs.

FAQ
What is the package type and lead count of the W25Q16JLSSIG TR?
The W25Q16JLSSIG TR uses an 8-pin SOIC package with 208-mil body width (Package Code SS). It has gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin plating. This variant is distinct from the 150-mil SOIC (SN), VSOP (SV), WSON (ZP), and USON (UX) variants - pinout and thermal characteristics are identical, but mechanical fit and reflow profile differ.
Does the W25Q16JLSSIG TR support Quad SPI operation out of the box?
No - Quad SPI operation requires explicit configuration of the Quad Enable (QE) bit in Status Register-2 (bit 1), which is non-volatile and defaults to 0. The W25Q16JLSSIG TR must first execute Write Status Register (01h) with QE=1 to enable IO2 (/WP) and IO3 (/HOLD) as data lines. Without this step, only Standard and Dual SPI modes are functional.
How does the /HOLD pin behave in Quad SPI mode on the W25Q16JLSSIG TR?
In Quad SPI mode (QE=1), the /HOLD pin of the W25Q16JLSSIG TR is repurposed as IO3 and the /HOLD function is disabled. The pin becomes a bidirectional data line for Quad I/O operations. To retain hold functionality, the design must operate in Standard or Dual SPI mode (QE=0), where /HOLD remains active-low and pauses ongoing transfers while /CS is asserted.
What is the purpose of the 64-bit Unique ID in the W25Q16JLSSIG TR?
The W25Q16JLSSIG TR includes a factory-programmed, read-only 64-bit Unique ID accessible via instruction 4Bh. It provides cryptographic binding for secure boot, device authentication, and firmware integrity verification - eliminating reliance on external EEPROM or MCU OTP for identity storage. Each W25Q16JLSSIG TR unit has a globally unique value guaranteed by Winbond.
Can the W25Q16JLSSIG TR be used in systems requiring -40°C to +85°C operation?
Yes - the W25Q16JLSSIG TR is rated for industrial temperature range (-40°C to +85°C) and specified across this range for all key parameters including 100K program/erase cycles, 20-year data retention, and 2.3–3.6 V supply operation. Its SOIC-208 package meets JEDEC MS-012 standards for thermal cycling and moisture sensitivity level (MSL3).
