GD25LQ16ENIGR

Memory IC Overview

The GD25LQ16ENIGR is a 16M-bit (2M x 8) SPI NOR Flash memory manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces, as well as QPI mode. The device operates on a single power supply voltage ranging from 1.65V to 2.1V. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key performance metrics include a maximum clock frequency of 133MHz for fast read operations, typical page program time of 0.4ms, sector erase time of 40ms, and block erase times of 0.15s or 0.2s. Standby current is typically 10μA, dropping to 1μA in deep power-down mode.

Memory IC Feature Summary

• Supports Standard, Dual, Quad SPI, and QPI modes for flexible data transfer rates up to 532Mbits/s.
• Includes advanced security features such as 128-bit Unique ID, software/hardware write protection, and three 3x1024-byte security registers with OTP locks.
• Features uniform sector architecture allowing efficient code storage and execute-in-place (XiP) operation.
• Provides high endurance with minimum 100,000 program/erase cycles and 20-year data retention.

Memory IC Applications

• Code storage for microcontrollers and SoCs
• Firmware storage in consumer electronics
• BIOS and boot code storage
• Parameter and configuration data storage

Memory IC Procurement Notes

Verify the specific ordering suffix 'ENIGR' against the manufacturer's official datasheet to confirm package type (USON8 3x4mm), temperature range, and lead-free status. Ensure compatibility with system voltage requirements (1.65V-2.1V). Check for RoHS compliance documentation. Confirm availability through authorized distributors as supply chain conditions may vary.

Memory IC Selection Notes

Select this component when a low-voltage (1.65V-2.1V) SPI NOR Flash with 16M-bit density is required. It is suitable for applications needing high-speed read access via Quad SPI or QPI modes. Consider the USON8 package size for space-constrained designs. Ensure the application does not require higher voltage levels (e.g., 3.3V) which would necessitate a different part number from the GD25Q series.

Memory IC Part Context

The GD25LQ16E series belongs to GigaDevice's family of Uniform Sector Dual and Quad Serial Flash memories. This series is designed for high-performance and low-power applications. The GD25LQ16ENIGR specifically denotes the 16M-bit variant in the USON8 package with industrial temperature range specifications, distinct from automotive-grade or wider voltage variants.

Memory IC Replacement Considerations

GD25LQ16CNIGR: Similar density and interface but may differ in voltage range or package specifics; verify electrical characteristics. GD25Q16ENIGR: Same package and pinout but operates at 2.7V-3.6V; requires level shifting or voltage rail adjustment if used as a direct replacement.

Memory IC FAQ

What is the difference between Quad SPI and QPI modes?

Quad SPI uses four I/O pins for data transfer while maintaining standard command structures. QPI mode switches all four I/O pins to handle both commands and data, offering potentially higher throughput but requiring specific command sets and disabling standard SPI functionality simultaneously.

How is write protection implemented in the GD25LQ16ENIGR?

Write protection can be achieved via software using Block Protect bits in the Status Register, hardware using the WP# pin, or by locking the Status Register permanently using One-Time Programmable (OTP) bits.
