GD25LT256EFARR

Memory IC Overview

The GD25LT256EFARR is a 256 Mbit NOR flash memory device manufactured by GigaDevice. It features an SPI interface with a maximum clock frequency of 166 MHz and operates within a supply voltage range of 1.65 V to 2 V. The memory organization is specified as 32 M x 8 bits. The component supports surface mount installation in an SOP-16 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface operations up to 166 MHz for efficient data transfer.
• Operates on ultra-low voltage power supplies ranging from 1.65 V to 2 V.
• Provides non-volatile storage with a density of 256 Mbits organized in 32M x 8 configuration.

Memory IC Applications

• Industrial control systems requiring low-power code storage
• Internet of Things (IoT) devices needing compact memory solutions
• Automotive electronics applications operating in industrial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'FARR' against official manufacturer documentation to confirm packaging details, as standard listings often reference 'EFIRR' or 'EFIRY'. Ensure compatibility with 1.65V to 2V power domains. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when system design requires ultra-low voltage operation between 1.65V and 2V combined with moderate speed requirements up to 166 MHz. The SOP-16 package offers a suitable footprint for space-constrained designs compared to BGA options. Consider alternative models like GD25Q series if higher voltage tolerance (2.7V-3.6V) or different packaging formats are required for the target application.

Memory IC Part Context

This part belongs to the GD25LT series, which represents GigaDevice's high-performance quad SPI NOR flash memory line designed for low-power applications. The LT series specifically targets ultra-low voltage environments, distinguishing it from standard voltage variants. It complements the broader portfolio including GD25Q and GD25LX series, offering a balance of density and power efficiency for embedded systems.

Memory IC Replacement Considerations

GD25LT256EFIRR: Identical electrical specifications and pinout; differs only in reel packaging format instead of tube/tray.
