GD25LQ32DNIGR

Memory IC Overview

The GD25LQ32DNIGR is a 32M-bit (4M x 8) Serial NOR Flash memory device manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V. The device supports Standard, Dual, Quad SPI, and QPI interfaces with a maximum clock frequency of 120MHz for fast read operations. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. Key electrical parameters include a typical page program time of 0.7ms, sector erase time of 90ms, block erase time of 0.3s or 0.45s, and chip erase time of 20s. Standby current is typically 35uA, while power-down current is 1μA.

• Provides high endurance with minimum 100,000 program/erase cycles and 20-year data retention capability.
• Enables Execute In Place (XIP) operation with continuous read support for 8/16/32/64-byte wrap.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring XIP functionality
• Consumer electronics devices needing compact form factor and low power consumption
• Industrial control systems requiring reliable non-volatile data storage
• IoT applications utilizing dual or quad SPI interfaces for higher throughput

Memory IC Procurement Notes

Verify the specific package suffix 'NI' against official ordering information tables to confirm the exact physical dimensions and pin configuration. Ensure compatibility with the required operating voltage range of 1.65V to 2.0V. Confirm that the design supports the necessary interface modes (Standard/Dual/Quad SPI or QPI) as defined in the datasheet command set.

Memory IC Selection Notes

Select this component when a 32M-bit capacity is required with a strict 1.8V power supply constraint. It is suitable for designs prioritizing low standby and power-down currents. Consider the available package options such as WSON or USON if space constraints are critical. Ensure the host controller supports the desired SPI mode (Dual/Quad/QPI) to leverage the higher data transfer speeds.

Memory IC Part Context

This part belongs to the GD25LQ32D series, which offers uniform sector architecture for consistent erase and program operations. The series is designed for applications demanding high reliability and security features. It complements other GigaDevice flash products by providing a specific 1.8V variant with robust data protection mechanisms and long-term retention characteristics.

Memory IC Replacement Considerations

Direct replacements within the same family include GD25LQ32DWIGR and GD25LQ32DLIGR, differing primarily in package type. Verify pinout compatibility and ensure the substitute part meets the same voltage and performance specifications.
