GD25LQ16C8IGR

Memory IC Overview

The GD25LQ16C8IGR is a 16M-bit (2M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single 1.65V to 2.1V power supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 104 MHz. The device features uniform 4K-byte sectors and 32/64K-byte blocks within an LGA-8 package measuring 3x2mm. It includes advanced security features such as hardware/software write protection, OTP lockable security registers, and a unique ID.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates
• Provides software and hardware write protection via WP# pin and status register bits
• Includes three 512-byte security registers with one-time programmable lock capability
• Features a 128-bit unique identifier embedded in each device

Memory IC Applications

• Firmware storage for microcontrollers and system-on-chips

• IoT module program memory

Memory IC Procurement Notes

Verify the specific suffix '8IGR' against the manufacturer's official ordering guide to confirm the LGA-8 3x2mm package and industrial temperature range (-40°C to +85°C). Ensure compatibility with existing PCB footprints for this specific package variant. Check for end-of-life or not-recommended-for-new-designations in current distributor catalogs before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside small form factor constraints. The LGA-8 3x2mm package offers a compact solution compared to standard SOP or USON variants. Consider the 104 MHz speed limit for high-throughput read requirements and ensure the design accommodates the specific voltage range of 1.65V to 2.1V.

Memory IC Part Context

This part belongs to the GD25LQ16C series of 1.8V uniform sector serial flash memories. It shares architectural similarities with other members like GD25LQ16CNIGR but differs in packaging and potentially thermal characteristics. The series is designed for cost-sensitive consumer and industrial applications requiring reliable non-volatile storage with moderate performance.
