GD25LQ16CSIG

Memory IC Overview

The GD25LQ16CSIG is a 16M-bit (2M x 8) SPI 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 a maximum clock frequency of 104 MHz. The device features uniform 4K-byte sectors and 32/64K-byte blocks within an 8-SOP package. It includes hardware and software write protection, a 128-bit unique ID, and three security registers with OTP locks.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates
• Provides advanced security with 128-bit unique ID and programmable security registers
• Features flexible architecture with uniform sector and block erase capabilities
• Includes hardware and software write protection mechanisms via WP# pin and status register bits

Memory IC Applications

• Code storage in embedded systems requiring Execute In Place (XIP)
• Data logging applications needing reliable non-volatile storage
• Firmware storage for microcontrollers and IoT devices
• Configuration parameter storage in industrial control systems

Memory IC Procurement Notes

Verify the specific suffix 'SIG' corresponds to the SOP-8 208mil package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure voltage levels match the 1.65V-2.1V specification. Check for any specific ordering suffix variations that might affect pinout or electrical characteristics.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is required with low voltage operation between 1.65V and 2.1V. It is suitable for designs needing high-speed read access up to 104 MHz via Quad SPI. Consider it if uniform sector size simplifies memory management compared to mixed sector architectures. Ensure the system can accommodate the 8-SOP package dimensions and thermal requirements.

Memory IC Part Context

Part of the GD25LQ16C series, which offers 1.8V uniform sector SPI NOR flash. This series is designed for cost-sensitive applications requiring moderate density and reliability. It complements GigaDevice's broader portfolio of 3V and automotive-grade flash memories, targeting consumer electronics and industrial markets where low power consumption and small form factors are prioritized.

Memory IC Replacement Considerations

GD25LQ16CTIG: Same electrical specifications but in SOP-8 150mil package. GD25LQ16CSIGR: Tape and reel packaging version of the same device. GD25Q16CSIG: 3.3V version, not directly compatible without voltage level adjustment.
