GD25LT256EFIRR

Memory IC Overview

The GD25LT256EFIRR is a 256 Mbit NOR flash memory device manufactured by GigaDevice. It features a 32 M x 8 organization and operates within a supply voltage range of 1.65 V to 2 V. The component utilizes an SPI interface with a maximum clock frequency of 166 MHz. It is housed in a 16-pin SOP package and supports surface mount installation. The device is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface communication up to 166 MHz
• Operates on low voltage power supplies between 1.65 V and 2 V
• Provides non-volatile data storage with 256 Mbit capacity

Memory IC Applications

• Industrial control systems requiring low voltage operation
• Consumer electronics utilizing SMD/SMT assembly
• IoT devices needing compact 16-SOP memory solutions

Memory IC Procurement Notes

Verify the specific suffix EFIRR against official datasheets to confirm the SOP-16 packaging and reel shipping format. Ensure the design accommodates the 1.65 V to 2 V supply requirement, as this differs from standard 3.3 V variants. Confirm compatibility with the -40°C to +85°C industrial temperature rating for the intended application environment before finalizing procurement.

Memory IC Selection Notes

Select this component when a 256 Mbit density is required alongside a strict 2 V maximum supply voltage constraint. The 166 MHz speed offers performance advantages over slower 133 MHz counterparts like the GD25B series. Consider the SOP-16 footprint if board space allows, noting that TFBGA options exist for higher density or smaller form factors.

Memory IC Part Context

This part belongs to the GD25L family of low-voltage NOR flash memories. It shares architectural similarities with the GD25LB and GD25LX series, which also operate at 1.65 V to 2 V and support 166 MHz speeds. The primary distinction lies in the specific package configuration and manufacturing revision indicated by the suffix.

Memory IC Replacement Considerations

GD25LB256EFIRR and GD25LX256EFIRR are electrically compatible alternatives within the same low-voltage family. Verify package availability and lead times for these substitutes if the primary part is unavailable.
