GD5F1GM7UEWIGY

Memory IC Overview

The GD5F1GM7UEWIGY is a 1Gb SLC NAND flash memory IC manufactured by GigaDevice. It utilizes an SPI Quad I/O interface with Double Data Rate (DTR) support, enabling clock frequencies up to 133 MHz and access times of 7 ns. The device features a 256M x 4 organization and operates within a voltage range of 2.7V to 3.6V. It is housed in an 8-WSON package measuring 5x6 mm and supports surface mount installation. The component is rated for an operating temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via SPI Quad I/O interface with Double Data Rate capability.
• Provides non-volatile storage using Single-Level Cell (SLC) NAND technology.
• Operates reliably across extended industrial temperature ranges.

Memory IC Applications

• Industrial control systems requiring robust data logging
• Consumer electronics firmware storage
• IoT devices needing compact non-volatile memory

Memory IC Procurement Notes

Verify the specific suffix 'WIGY' against official GigaDevice datasheets to confirm package dimensions and pinout compatibility. Ensure supply chain sources provide valid RoHS compliance documentation. Check for any temporary supply restrictions or allocation limits that may affect procurement timelines. Confirm the manufacturer is Gigadevice Electronics Singapore PTE.LTD. as listed in distributor records.

Memory IC Selection Notes

Select this component when a 1Gb capacity is required in a small 8-WSON footprint. The DTR interface offers higher throughput compared to standard SPI modes. Verify that the host controller supports the 133 MHz clock frequency and 2.7V-3.6V supply requirements. Consider the -40°C to 85°C rating if the application environment exceeds commercial temperature limits.

Memory IC Part Context

This part belongs to the GD5F series of SPI NAND flash memories from GigaDevice. The series is designed for applications demanding high performance and reliability in a compact form factor. The GD5F1GM7 variant specifically targets 1Gb storage needs with advanced interface speeds.

Memory IC Replacement Considerations
