GD25LB256E3IRR

Memory IC Overview

The GD25LB256E3IRR is a 256M-bit (32M x 8) Serial NOR Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.0V and supports Standard SPI, Quad SPI, QPI, and DTR Quad I/O interfaces with a maximum clock frequency of 166MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware/software write protection, OTP lockable security registers, and a unique ID. The component is designed for high-speed read operations and low power consumption.

Memory IC Feature Summary

• Supports multiple interface modes including Standard SPI, Quad SPI, QPI, and DTR Quad I/O for flexible data transfer speeds.
• Provides comprehensive data protection through software-configurable block protection and hardware WP# pin locking.
• Integrates a dedicated RESET# pin for immediate hardware reset functionality independent of operational states.
• Features non-volatile configuration registers allowing persistent storage of device settings across power cycles.

Memory IC Applications

• Code storage in embedded systems requiring Execute In Place (XIP) capabilities
• Firmware storage for IoT devices and consumer electronics
• Data logging applications needing reliable non-volatile memory retention
• Automotive infotainment and control unit code storage

Memory IC Procurement Notes

Verify the specific package type associated with the suffix 'I' against official datasheets, as it may indicate WLCSP or other small form factors distinct from standard SOP/WSON variants. Confirm operating temperature range requirements match the industrial grade specifications. Ensure voltage levels align strictly with the 1.65V-2.0V supply constraint. Check for automotive qualification status if used in safety-critical environments.

Memory IC Selection Notes

Select this component when high-density code storage is required within a constrained voltage envelope of 1.65V to 2.0V. It is suitable for designs prioritizing low standby current and fast read access times via DTR or QPI modes. Consider its uniform sector architecture for simplified erase management compared to mixed-sector alternatives. Evaluate package availability for the specific suffix variant to ensure compatibility with PCB footprint constraints.

Memory IC Part Context

This part belongs to the GD25LB series of Serial NOR Flash memories from GigaDevice. The series is characterized by its support for DTR Quad I/O operations and low-voltage operation. It complements other densities in the family by offering 256M-bit capacity with robust security features and flexible interface options for modern embedded applications.

Memory IC Replacement Considerations

GD25LB256EFIRR: Similar density and voltage but may differ in package (SOP-16 vs potential WLCSP). Verify interface command set compatibility. GD25LB256EYEGR: Offers wider temperature range (-40°C to +125°C) and potentially different package (WSON-8). Check if extended temperature rating is required for the application environment.
