GD55X01GEF2RR

Memory IC Overview

The GD55X01GEF2RR is a 1 Gbit NOR flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 2.7 V to 3.6 V and supports DTR SPI, OPI, and standard SPI interfaces. The component achieves a maximum clock frequency of 200 MHz with synchronous timing. Designed for surface mount installation, it is housed in a package supplied in reels. The operational temperature range extends from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via Dual/Quad/Octal I/O modes
• Provides non-volatile code storage for system booting
• Compatible with standard SPI command sets

Memory IC Applications

• Consumer electronics firmware storage
• Industrial control systems
• IoT device code execution

Memory IC Procurement Notes

Verify the specific suffix 'EF2RR' against official datasheets to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the 3V operating voltage aligns with target system power rails before integration.

Memory IC Selection Notes

Select this part when a 1 Gbit density is required with a 3V supply rail. The 200 MHz speed supports high-performance applications. Compare against the GD55LX series if a lower 1.8V supply voltage is necessary for the design. Verify pin compatibility if replacing existing components.

Memory IC Part Context

This component belongs to the GD55 series of SPI NOR flash memories from GigaDevice. The series offers densities up to 2 Gbit. These devices are designed for embedded applications requiring reliable code storage. The family supports various interface speeds and package options to suit different form factors.

Memory IC Replacement Considerations

GD55X01GEB2RY shares similar electrical characteristics but uses a TFBGA-24 package instead of SOP-16. Cross-reference pinouts and thermal requirements carefully. No other direct substitutes are confirmed in public documentation.
