GD5F2GQ5UEBIGY

Memory IC Overview

The GD5F2GQ5UEBIGY is a 2 Gbit SLC NAND Flash memory device manufactured by GigaDevice. It utilizes a TFBGA-24 package and operates with a single power supply voltage ranging from 2.7 V to 3.6 V. The device features an SPI interface supporting Standard, Dual, Quad, and DTR modes, with a maximum clock frequency of 104 MHz at 3.3V. It offers a page size of 2048 bytes plus 128 bytes of spare area when internal ECC is disabled, or 2048 bytes plus 64 bytes when ECC is enabled. The operating temperature range is -40°C to +85°C.

Memory IC Feature Summary

• Supports multiple SPI communication modes including Standard, Dual, Quad, and Double Transfer Rate (DTR) for flexible data throughput.
• Integrates internal Error Correction Code (ECC) capability to ensure data integrity during read and program operations.
• Provides hardware and software write protection mechanisms to safeguard memory content against unauthorized modifications.
• Features a cache register architecture that enables fast random reads and efficient sequential page access.

Memory IC Applications

• Embedded systems requiring high-density non-volatile code storage
• Consumer electronics devices needing reliable firmware retention
• Industrial control applications demanding wide temperature operation
• IoT modules utilizing low-pin-count memory solutions

Memory IC Procurement Notes

Verify the specific ordering suffix BIGY corresponds to the TFBGA-24 package and industrial temperature grade (-40°C to +85°C). Confirm the voltage range matches the UE variant (2.7V to 3.6V). Ensure design compatibility with the 24-ball BGA footprint and pinout configuration before finalizing procurement.

Memory IC Selection Notes

Select this component for designs requiring 2 Gbit capacity in a compact surface-mount package. It is suitable for applications needing robust data retention and endurance with integrated ECC. Consider the TFBGA-24 form factor if board space is constrained but higher pin counts than WSON are acceptable for improved thermal and electrical performance.

Memory IC Part Context

This part belongs to the GD5F2GQ5xExxG series of SPI NAND Flash memories. The 'UE' designation indicates the 3.3V voltage variant, while 'BIGY' specifies the TFBGA-24 package and industrial temperature rating. It shares the same command set and core architecture as other variants in the family, differing primarily in package type and operating conditions.

Memory IC Replacement Considerations

GD5F2GQ5UEYIGY: Same electrical specifications and density, but uses a WSON-8 package instead of TFBGA-24. Requires PCB layout redesign due to different pinout and physical dimensions.

Memory IC FAQ

What is the default state of the internal ECC feature?

The internal ECC is enabled by default (ECC_EN=1). Users can disable it via feature register settings if needed.

How does the DQS pin function in the TFBGA-24 package?

The DQS pin provides a Data Strobe Signal Output specifically for DTR Quad SPI mode to improve data capture accuracy at high speeds.
