GD25LQ64CSIG

Memory IC Overview

The GD25LQ64CSIG is a 64 Mbit SPI NOR Flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2 V and supports standard, dual, and quad SPI interfaces with clock frequencies up to 133 MHz. The memory is organized as 8M x 8 bits and housed in an 8-SOP package. It functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports Dual and Quad I/O data transfer modes for enhanced read performance
• Features uniform sector architecture for consistent erase operations
• Operates on low voltage power supplies suitable for portable applications

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics utilizing low-power flash memory
• Industrial control devices needing wide temperature operation

Memory IC Procurement Notes

Verify the specific suffix 'SIG' against official datasheets to confirm the SOP-8 package and lead-free status. Confirm current production status as distributors may list obsolete or discontinued variants under similar part numbers. Ensure compatibility with 1.65V to 2V system rails before procurement.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity is required with strict low-voltage constraints between 1.65V and 2V. Compare against the GD25Q series if 3.3V operation is acceptable, or the GD25LQ64ESIG if higher clock speeds are needed. Verify that the SOP-8 package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the GD25LQ64 family of low-voltage serial flash memories. It shares architectural similarities with other members like the GD25LQ64ESIG but differs in maximum clock speed and specific electrical characteristics defined by the manufacturer's product selection guide.

Memory IC Replacement Considerations

GD25LQ64ESIG is a recommended replacement offering higher clock speeds within the same voltage range.
