GD25LB256FFIRR

Memory IC Overview

The GD25LB256FFIRR is a 256 Mbit SPI NOR Flash memory device manufactured by GigaDevice. It features a storage organization of 32 M x 8 and supports standard SPI, Quad I/O, QPI, and DTR interfaces with a maximum clock frequency of 166 MHz. The component operates within a supply voltage range of 1.65 V to 2 V and functions at temperatures between -40°C and +85°C. It is housed in a 16-SOP package.

Memory IC Feature Summary

• Supports high-speed data transfer via Quad I/O, QPI, and DTR modes
• Operates on ultra-low voltage power supplies for energy efficiency
• Includes hardware-based ECC algorithms and CRC checksums for data integrity

Memory IC Applications

• Automotive infotainment systems
• Advanced driver assistance systems (ADAS)
• Industrial control units

Memory IC Procurement Notes

Verify the specific suffix 'FF' against official manufacturer documentation to confirm interface and package variations. Ensure the 1.65V-2V operating voltage aligns with target system rails. Confirm availability status as distribution channels may report limited stock or obsolescence warnings for this specific variant.

Memory IC Selection Notes

Select this part when low voltage operation is required alongside high-speed serial access. Compare against the GD25F series if a wider 2.7V-3.6V voltage range is acceptable. Verify that the SOP-16 package fits the PCB layout constraints and thermal requirements of the final assembly.

Memory IC Part Context

This component belongs to the GD25LB family, which targets ultra-low power applications. It complements the broader GD25/55 portfolio designed for automotive and industrial sectors. The LB series specifically addresses needs for reduced power consumption while maintaining high performance standards.

Memory IC Replacement Considerations

GD25LB256EFIRR: Similar capacity and voltage range but uses SOP-16 package instead of WSON-8.
