GD25LQ32EEEGR

Memory IC Overview

The GD25LQ32EEEGR is a 32M-bit Serial Flash memory device manufactured by GigaDevice. It supports Standard, Dual, Quad SPI, and QPI interfaces with a maximum clock frequency of 133 MHz for fast read operations under a 30 pF load. The device operates on a single power supply voltage ranging from 1.65V to 2.0V. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key electrical characteristics include a typical standby current of 10μA and deep power-down current of 1μA. The memory organization consists of 4M x 8 bits, organized into pages of 256 bytes.

Memory IC Feature Summary

• Supports Standard, Dual, Quad SPI, and QPI modes for flexible data transfer rates up to 532 Mbits/s in Quad I/O and QPI modes.
• Provides advanced security features including 128-bit Unique ID, software/hardware write protection via WP# pin, and three 3x1024-byte security registers with OTP locks.
• Enables Execute In Place (XiP) operation with continuous read with wrap functionality to reduce instruction fetch time and fill SoC cache.
• Offers reliable endurance with minimum 100,000 Program/Erase cycles and typical 20-year data retention.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring low voltage operation
• Embedded systems needing secure boot code and firmware storage
• Battery-powered devices benefiting from ultra-low standby and deep power-down currents
• Applications requiring hardware-level write protection for critical data

Memory IC Procurement Notes

Verify the specific package variant corresponding to the EEEGR suffix against the manufacturer's official ordering information table. Confirm that the required operating voltage range aligns with the 1.65V to 2.0V specification. Ensure design compatibility with the supported SPI and QPI command sets. Check for any specific RoHS or environmental compliance certifications required for your region.

Memory IC Selection Notes

Select this component when a 32M-bit capacity is required with strict low-voltage constraints between 1.65V and 2.0V. It is suitable for designs prioritizing high-speed Quad I/O or QPI data throughput. Consider this part for applications needing integrated security features like unique IDs and hardware write protection. Ensure the host controller supports the necessary SPI modes and command sequences for optimal performance.
