GD55B02GEBIRY

Memory IC Overview

The GD55B02GEBIRY is a 2G-bit Serial NOR Flash memory device manufactured by GigaDevice. It supports Standard SPI, Quad SPI, DTR, and QPI interfaces with a maximum clock frequency of 133MHz. The device features a uniform sector architecture comprising 64K-byte blocks and 4K-byte sectors, organized into 256M-bytes total capacity. It operates within a voltage range of 2.7V to 3.6V and utilizes a TFBGA-24 package (5x5 ball array). Key performance metrics include typical page program times of 0.15ms, sector erase times of 30ms, and block erase times of 0.15s or 0.22s.

Memory IC Feature Summary

• Supports multiple interface modes including Standard SPI, Quad SPI, DTR, and QPI for flexible data transfer rates.
• Features advanced security mechanisms such as hardware/software write protection, individual block locking, and OTP lockable security registers.
• Provides high endurance with 100,000 program/erase cycles and 20-year data retention capability.
• Includes a 128-bit Unique ID for device identification and authentication.

Memory IC Applications

• Code storage for embedded systems requiring XIP (Execute In Place) operations.
• Firmware storage in industrial control and IoT devices.
• Data logging and configuration storage in automotive electronics.
• BIOS and boot code storage in consumer electronics.

Memory IC Procurement Notes

Verify the specific suffix 'BIRY' against the manufacturer's official ordering information table to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with the required voltage range and interface modes for your system design. Cross-reference the datasheet revision date with your project timeline to account for any potential updates in electrical characteristics or command sets.

Memory IC Selection Notes

Select this component when a high-density 2G-bit storage solution is required with support for high-speed DTR and QPI modes. Consider the TFBGA-24 package constraints and ensure the PCB layout accommodates the 5x5 ball array. Verify that the system power supply remains stable within the 2.7V to 3.6V range to maintain reliable operation and data integrity during program and erase cycles.

Memory IC Part Context

The GD55B02GE belongs to GigaDevice's GD55 series of uniform sector serial flash memories. This series is designed for applications demanding high performance and reliability. The GD55B02GE specifically offers 2G-bit density, distinguishing it from lower-capacity variants like the GD55B01GE (1Gb) or higher-density models. It shares architectural similarities with other GD55 family members but provides unique capacity and pinout configurations suitable for large-scale code storage.

Memory IC FAQ

What is the default address mode upon power-up?

Upon power-up, the device defaults to 3-Byte Address Mode. It can be switched to 4-Byte Address Mode using the Enable 4-Byte Mode command.

How does the device handle Program/Erase Suspend?

The device supports Program/Erase Suspend via the PES command. Status bits SUS1 and SUS2 indicate whether an erase or program operation is suspended, respectively. Operations resume upon issuing the PER command.

Can the Security Registers be modified after being locked?

No. The Lock Bit (LB) in the Status Register is One Time Programmable (OTP). Once set to 1, the Security Registers become permanently read-only and cannot be modified again.
