GD25LX256EFIRR

Memory IC Overview

The GD25LX256EFIRR is a 256 Mbit NOR flash memory device manufactured by GigaDevice. It features an SPI interface with a maximum clock frequency of 166 MHz and operates within a supply voltage range of 1.65 V to 2 V. The memory organization is specified as 32 M x 8 bits, providing an 8-bit data bus width. The component is designed for surface mount installation in SOP-16 packages and supports operation across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface communication
• Operates on low voltage power supplies suitable for portable devices
• Provides non-volatile code storage with execute-in-place capability

Memory IC Applications

• Embedded systems requiring compact code storage
• Consumer electronics with space constraints
• Industrial control applications

Memory IC Procurement Notes

Verify the specific suffix EFIRR against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements of 1.65 V to 2 V before integration. Confirm lead times and availability directly with authorized distributors as stock levels fluctuate.

Memory IC Selection Notes

Select this part when a 256 Mbit capacity is required in an SOP-16 package. It is suitable for designs needing 166 MHz SPI speeds and low voltage operation. Compare against GD25LX256EBJRR if TFBGA packaging is preferred instead of SOP-16.

Memory IC Part Context

This component belongs to the GD25LX series of high-performance Octal SPI NOR Flash memories from GigaDevice. The series targets applications demanding high read throughput and efficient execute-in-place operations. While the broader family supports up to 200 MHz frequencies, this specific variant is documented at 166 MHz.

Memory IC Replacement Considerations

GD25LX256EBJRR offers identical electrical specifications but utilizes a TFBGA24 package instead of SOP-16.
