GD25LT512MEYIGR

Memory IC Overview

The GD25LT512MEYIGR is a 512 Mbit NOR flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2.0 V and supports SPI interface communication with a maximum clock frequency of 166 MHz. The component is housed in an SOP-16 surface-mount package and is designed for industrial temperature environments ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports Single I/O, Quad I/O, QPI, and DTR bus modes
• Integrates hardware-based ECC algorithms and CRC checksums
• Includes security registers with OTP locks and unique ID functionality

Memory IC Applications

• Industrial embedded systems requiring low-voltage operation
• IoT devices with strict power constraints
• Network communication equipment storage

Memory IC Procurement Notes

Verify the specific suffix YIGR against official datasheets to confirm the SOP-16 packaging and 1.65V-2.0V voltage range specifications. Ensure compatibility with system voltage levels prior to integration. Confirm lead times and availability directly with authorized distributors as stock status varies.

Memory IC Selection Notes

Select this component when a 512 Mbit density is required alongside a low 1.65V-2.0V operating voltage profile. The SOP-16 package is suitable for applications where board space allows for larger footprints compared to WSON options. Verify that the 166 MHz clock speed meets the system's data throughput requirements.

Memory IC Part Context

This part belongs to the GD25LT series, which is engineered for low-voltage applications. Unlike the standard 3V GD25T or automotive GD25B series, the LT variant specifically targets 1.65V-2.0V domains. It shares feature sets like ECC and security registers with other modern GigaDevice NOR flash families but differs in voltage tolerance and package options.

Memory IC Replacement Considerations

GD25LT512MEFIRY (SOP-16 Tray) and GD25LT512MEBIRY (TFBGA-24 Tray) are documented variants within the same family. Cross-referencing the exact suffix is critical as it dictates the physical package type and reel/tray configuration.
