GD25LQ40EEEGR

Memory IC Overview

The GD25LQ40EEEGR is a 4 Mbit NOR flash memory IC from GigaDevice, organized as 512K x 8 bits. It operates within a supply voltage range of 1.65 V to 2 V and supports SPI interfaces including Dual/Quad SPI and QPI modes. The device features a maximum clock frequency of 133 MHz and functions reliably across an extended industrial temperature range of -40°C to +125°C. Packaged in an 8-USON (3x2 mm) surface-mount format with exposed pads, it is designed for compact embedded storage applications requiring low-voltage operation.

Memory IC Feature Summary

• Supports high-speed Quad SPI and QPI interface protocols for enhanced data throughput
• Operates on a low-voltage power supply ranging from 1.65 V to 2 V
• Engineered for reliable performance in extended industrial temperature environments up to 125°C

Memory IC Applications

• Embedded systems requiring non-volatile code execution
• IoT devices with strict space and power constraints
• Industrial control units operating in harsh thermal conditions

Memory IC Procurement Notes

Verify the specific suffix EEEGR against official datasheets to confirm the 125°C temperature grade and USON-8 package variant. Ensure design compatibility with the 1.65 V to 2 V supply rail, as this differs from standard 3 V parts. Confirm RoHS compliance status and moisture sensitivity level requirements during assembly planning.

Memory IC Selection Notes

Select this component when designs require low-voltage operation below 2.7 V combined with extended temperature capabilities. Compare against the GD25LQ40CTIGR if an 8-SOP package or 85°C rating suffices. Consider the GD25Q40 series only if a higher 3.6 V supply voltage is available, noting that the LQ series is optimized for lower power consumption.

Memory IC Part Context

This part belongs to the GD25LQ family of low-voltage SPI NOR flash memories. It shares architectural similarities with other members like the GD25LQ32EEEGR but offers a smaller 4 Mbit capacity. The EEGR suffix specifically denotes the 125°C industrial grade and USON-8 packaging, distinguishing it from standard commercial grade variants.
