GD55X02GEBIRY

Memory IC Overview

The GD55X02GEBIRY is a 2 Gbit Single-Level Cell (SLC) NOR Flash memory IC manufactured by GigaDevice. It utilizes an SPI interface with Octal I/O and Double Data Rate (DTR) capabilities, supporting clock frequencies up to 200 MHz. The device operates within a supply voltage range of 1.65 V to 2 V and is housed in a 24-TFBGA (6x8) package. It supports a memory organization of 256M x 8 bits and functions reliably across an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via SPI Octal I/O with Double Data Rate (DTR) signaling
• Provides non-volatile code storage using Single-Level Cell (SLC) technology
• Designed for surface-mount installation in compact electronic systems

Memory IC Applications

• Mobile devices requiring efficient code execution
• Embedded systems needing reliable boot code storage
• Consumer electronics utilizing small form-factor memory solutions

Memory IC Procurement Notes

Verify the specific speed grade against official datasheets, as variants exist with different maximum clock frequencies. Confirm the exact package dimensions and pinout compatibility with your PCB layout. Ensure power supply rails strictly adhere to the 1.65 V to 2 V specification to prevent device malfunction or damage during operation.

Memory IC Selection Notes

Select this component when high-density SLC NOR flash is required with fast read speeds. The Octal DTR interface offers significant bandwidth advantages over traditional Quad-SPI modes. Consider the 24-TFBGA package constraints and thermal management requirements for dense board designs. Validate that the system voltage domain matches the 1.8V nominal supply requirement.

Memory IC Part Context

This part belongs to the GD55 series of SPI NOR Flash memories from GigaDevice. The series targets applications demanding high performance and reliability. It complements other density options within the family, providing scalable storage solutions for modern embedded and mobile hardware architectures.

Memory IC Replacement Considerations

Check for GD55LX02GEBIRY, which shares similar specifications but may operate at a lower maximum clock frequency of 166 MHz compared to the 200 MHz capability of the GD55X02GEBIRY. Verify functional equivalence before substitution.
