GD55B01GEFIRR

Memory IC Overview

The GD55B01GEFIRR is a 1 Gbit NOR flash memory device manufactured by GigaDevice. It features a 128 M x 8 organization and supports SPI, Quad I/O, QPI, and DTR interfaces with a maximum clock frequency of 133 MHz. The component operates within a voltage range of 2.7 V to 3.6 V and has a maximum active read current of 50 mA. It is housed in a 16-SOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports multiple interface modes including Standard SPI, Quad I/O, QPI, and Double Data Rate (DTR) for flexible system integration.
• Includes hardware reset and write-protect capabilities alongside security registers with OTP locks for data protection.
• Provides suspend functionality to allow processor access during non-critical memory operations.

Memory IC Applications

• Code storage for embedded systems requiring high reliability
• Industrial control applications needing wide temperature operation
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix FIRR corresponds to the SOP-16 reel packaging configuration before ordering. Confirm that the 133 MHz clock speed requirement aligns with your system design constraints. Ensure voltage levels remain strictly within the 2.7 V to 3.6 V operational limits to prevent device malfunction or damage during implementation.

Memory IC Selection Notes

Select this part when a 1 Gbit density is required in a 16-pin SOP package. It is suitable for designs needing Quad SPI or DTR performance at 133 MHz. Consider alternative packages like WSON-8 or TFBGA-24 if board space is limited or if different thermal characteristics are needed for the application environment.

Memory IC Part Context

This component belongs to the GD55B series of SPI NOR flash memories from GigaDevice. The series offers various densities and package options to support diverse storage needs. The GD55B01GEFIRR specifically addresses requirements for industrial-grade non-volatile storage with robust interface support and standard surface-mount compatibility.

Memory IC Replacement Considerations

GD55B01GEFJRR offers similar specifications but includes an extended temperature range up to +105°C. Other variants in the GD55B01GE family provide different package types such as WSON-8 or TFBGA-24 while maintaining core electrical performance.
