GD25LT512MEFIRR

Memory IC Overview

The GD25LT512MEFIRR is a 512 Mbit SPI NOR Flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2.0 V and supports industrial temperature ranges including -40°C to +85°C, -40°C to +105°C, and -40°C to +125°C. The component utilizes an SPI interface with Single I/O, Quad I/O, QPI, and DTR modes, achieving clock frequencies up to 166 MHz in x1/x4 modes and 200 MHz in x4 DTR mode. It is housed in a SOP-16 package.

Memory IC Feature Summary

• Supports hardware reset functionality via dedicated pin
• Includes security registers with OTP lock capabilities
• Features built-in ECC for data integrity enhancement

Memory IC Applications

• Industrial embedded systems requiring wide temperature tolerance
• Automotive-grade applications meeting AEC-Q100 standards
• Code storage for microcontrollers in harsh environments

Memory IC Procurement Notes

Verify the specific temperature grade (85°C, 105°C, or 125°C) required for your application, as the GD25LT512ME series covers multiple industrial ranges. Confirm package availability matches the SOP-16 specification. Ensure voltage compatibility with the 1.65V–2.0V operating range before integration into low-power designs.

Memory IC Selection Notes

Select this component when low-voltage operation between 1.65V and 2.0V is mandatory. Consider the LT series variants if extended high-temperature performance beyond standard industrial limits is needed. Compare against the GD25LB series if automotive qualification is not required but similar electrical characteristics are desired.

Memory IC Part Context

This part belongs to the GD25L family of SPI NOR Flash memories designed for low-voltage applications. It complements the broader GD25/55 portfolio which includes automotive-grade options certified to ISO 26262 ASIL D. The LT designation typically indicates specific temperature and feature sets within the low-voltage segment.

Memory IC Replacement Considerations

GD25LB512MEFIRR: Similar voltage and density but lacks the extended temperature grades of the LT series. GD25LR512MF: Different interface speeds and package options; verify pinout compatibility.
