GD25LB512MFFIRR

Memory IC Overview

The GD25LB512MFFIRR is a 512Mb SPI NOR Flash memory IC manufactured by GigaDevice. It utilizes SLC NAND technology and supports SPI, Quad I/O, and QPI interfaces with a maximum clock frequency of 133 MHz. The device operates within a supply voltage range of 1.65V to 2V and features a 64M x 8 organization. It is housed in a 16-SOP package and is designed for industrial applications with an operating temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via SPI, Quad I/O, and QPI modes at frequencies up to 133 MHz.
• Operates on a low-voltage power supply ranging from 1.65V to 2V for energy-efficient performance.
• Provides non-volatile storage using SLC flash technology with a 512Mb capacity.

Memory IC Applications

• Industrial control systems requiring reliable code storage
• Consumer electronics devices utilizing low-voltage power supplies
• Embedded systems needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'IRR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and quantity per reel. Ensure that the 1.65V to 2V voltage requirement aligns with your system's power rail specifications before integration. Confirm RoHS3 compliance status if required by your regional regulations or end-product standards.

Memory IC Selection Notes

Select this component when a 512Mb density is required alongside a 16-pin SOP footprint. The 1.65V-2V operating range distinguishes it from standard 3V parts, making it suitable for low-power designs. Verify that the 133 MHz interface speed meets the bandwidth requirements of your application compared to other series variants.

Memory IC Part Context

This part belongs to the GD25LB series of SPI NOR Flash memories from GigaDevice. The series targets applications demanding high performance and low power consumption. It shares architectural similarities with other 512Mb devices in the portfolio but differs in voltage specifications and package options.

Memory IC Replacement Considerations

Direct substitutes include GD25LB512MEFIRR (SOP-16) and GD25B512MFFIRR (note: different voltage range). Verify pin compatibility and voltage levels carefully before swapping components.
