GD25LQ32DQIGR is a 32‑Mbit serial flash memory from GigaDevice (GD25LQ family). It provides a Quad I/O (QIO) serial interface but also supports standard SPI and dual I/O modes, for flexible signaling.
Key features:
- 4 MB of flash storage (32 Mbit)
- Voltage: 2.7–3.6 V
- Fast read up to ~104 MHz SPI; Quad I/O read modes available
- Page program (256 bytes) and block erases (4 KB, 32 KB, 64 KB)
- Write enable, status/protection registers, deep power-down
- 8‑pin package; RoHS-compliant; industrial temperature grade (suffix IG R)
Typical use:
- Firmware/boot code storage for microcontrollers and embedded systems
Note:
- For exact electrical/timing specs and command set, refer to the GD25LQ32DQIGR datasheet from GigaDevice.

Note: exact temp range and packaging variant may depend on the specific grade (industrial/commercial) and revision.

- Pin count: 8 pins (SOP-8).
- Function: GD25LQ32DQIGR is a 32 Mbit serial NOR flash memory with SPI interface supporting dual/quad I/O (DQ) reads. Pinout typically: CS, CLK, DI (MOSI), DO (MISO), WP#, HOLD#, VCC, VSS. Used to store firmware/data.

- Manufacturer: GigaDevice Semiconductor Inc. (GigaDevice)
- What kind of company: A Chinese fabless semiconductor company that designs and markets memory products, especially serial NOR/NAND flash and related embedded memory solutions (and related MCUs).

GD25LQ32DQIGR is a 32-Mbit quad-SPI serial NOR flash. Typical applications include:
- Boot and firmware storage for MCUs/SoCs
- OTA firmware updates in IoT, consumer electronics, and wearables
- Non-volatile data logging and parameter storage in automotive, industrial, and medical devices
- Code storage for networking equipment (routers, gateways, modems)
- FPGA/SoC configuration bitstreams and peripheral data
- Embedded graphics/UI firmware in set-top boxes, displays, and multimedia devices
These use cases exploit its non-volatile storage, fast Quad SPI interfaces, and compact packaging.

It uses an 8-pin SOP (SOIC) package; the “GR” suffix denotes a RoHS-compliant lead-free variant.
