GD25LQ16C

Updated: 2026-08-05

Overview

The GD25LQ16C is a serial peripheral interface (SPI) NOR flash memory chip manufactured by GigaDevice. It provides 16Mbit (2MB) of storage, making it suitable for firmware storage, boot code, and parameter retention in embedded systems. The chip operates over a wide voltage range and supports high-speed data transfer, ensuring efficient performance in demanding applications. Its compact form factor and low power consumption make it ideal for portable and battery-powered devices. The GD25LQ16C is widely used in consumer electronics, industrial automation, and automotive systems due to its reliability and cost-effectiveness.

Structure and Working Principle

The GD25LQ16C is built on floating-gate MOSFET technology, enabling non-volatile data storage. It communicates with a host microcontroller via the SPI bus, supporting clock frequencies up to 104MHz. The memory is organized into sectors and blocks, allowing flexible erase and write operations. Data retention is guaranteed for up to 20 years, with a minimum of 100,000 program/erase cycles per sector. The chip includes hardware and software write protection features to prevent accidental data corruption. Its internal architecture ensures fast access times, with typical page program times of 0.7ms and sector erase times of 60ms.

Key Features

The GD25LQ16C stands out for its low power consumption, with active read current as low as 4mA and deep power-down mode reducing consumption to 1µA. It supports a wide operating temperature range (-40°C to 85°C), making it suitable for industrial and automotive environments. The chip also features a unique 64-bit serial number for device identification and security applications. Its robust design includes ECC (Error Correction Code) functionality to enhance data integrity. With a small 8-pin SOP or WSON package, it saves board space while delivering high performance.

Application Areas

The GD25LQ16C is extensively used in IoT devices for firmware storage and wireless module configurations. In automotive electronics, it stores calibration data and bootloaders for infotainment systems and ECUs. Industrial applications include programmable logic controllers (PLCs) and sensor modules. Consumer electronics such as smart home devices, wearables, and gaming peripherals also leverage this memory chip for its reliability. Its compatibility with standard SPI interfaces ensures easy integration into existing designs, reducing development time and costs.

Maintenance and Precautions

To ensure optimal performance, avoid exposing the GD25LQ16C to electrostatic discharge (ESD). Use proper handling techniques, including grounding straps during installation. Adhere to the specified voltage limits to prevent damage to the memory cells. For soldering, follow the manufacturer's recommended reflow profile to avoid thermal stress. Regularly update firmware to address potential bugs or security vulnerabilities. Store unused chips in anti-static packaging to maintain their integrity over time.

B2B Procurement Guide

When procuring the GD25LQ16C in bulk, verify the supplier's authenticity to avoid counterfeit products. Request samples for testing compatibility with your system. Check for industry certifications such as AEC-Q100 for automotive applications. Negotiate pricing based on order volume, with discounts typically available for quantities exceeding 1,000 units. Ensure the supplier provides adequate technical support and documentation, including datasheets and application notes. Lead times may vary, so plan inventory accordingly.
