GD25LR128EWIGR

Memory IC Overview

The GD25LR128EWIGR is a 128 Mbit NOR flash memory IC manufactured by GigaDevice. It utilizes an SPI Quad I/O interface and operates within a supply voltage range of 1.65 V to 3.6 V, supporting low-voltage applications. The device features a 133 MHz clock frequency and is housed in an 8-WSON package. It supports Single-Level Cell (SLC) technology and includes Low Power Read Mode capabilities for energy efficiency.

Memory IC Feature Summary

• Supports Low Power Read Mode to reduce active current consumption during read operations
• Compatible with standard SPI and Quad I/O protocols for flexible interface integration
• Operates across a wide supply voltage range from 1.65 V to 3.6 V

Memory IC Applications

• Low-power embedded systems requiring extended battery life
• IoT devices with strict power consumption constraints
• Industrial control units utilizing SLC NOR flash for code storage

Memory IC Procurement Notes

Verify the specific suffix 'LR' indicates Low Power Read functionality compared to standard variants. Confirm package availability as WSON-8. Check moisture sensitivity level requirements for surface mount assembly processes. Ensure voltage compatibility with system rails ranging from 1.65 V to 3.6 V before integration.

Memory IC Selection Notes

Select this component when both low voltage operation and reduced read power are required. Compare against GD25LE128E for standard low-voltage needs or GD25B128E for standard 2.7V-3.6V applications. The LR variant offers enhanced power efficiency without sacrificing the 133 MHz performance typical of the GD25 series.

Memory IC Part Context

This part belongs to the GD25L series of SPI NOR flash memories. It shares the 128 Mbit capacity and 8-WSON form factor with other members like GD25LE128E and GD25Q128E. The distinguishing feature is the optimized power consumption profile for read-intensive low-power applications.

Memory IC Replacement Considerations

GD25LE128EWIGR serves as a functional substitute if Low Power Read Mode is not critical. GD25B128EWIGR is suitable if the system operates strictly at 2.7 V to 3.6 V and does not require the 1.65 V minimum capability.
