GD25Q40EKIGR

Memory IC Overview

The GD25Q40EKIGR is a 4 Mbit Serial NOR Flash memory manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 133 MHz for fast read operations. The device operates within a voltage range of 2.7 V to 3.6 V and features a USON-8 package. It includes uniform sector and block architectures, hardware/software write protection, and advanced security features such as a unique ID and security registers.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates
• Includes software and hardware write protection mechanisms via status register bits
• Features advanced security with 128-bit unique ID and OTP security registers
• Enables Execute In Place (XiP) operation for reduced instruction fetch latency

Memory IC Applications

• Code storage in embedded systems requiring XIP capability
• Consumer electronics firmware storage
• Industrial control system data logging
• IoT device configuration and parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'EKIGR' against the manufacturer's official ordering guide to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the USON-8 package. Confirm that the required Quad Enable (QE) bit configuration aligns with the system design, as it alters pin functions.

Memory IC Selection Notes

Select this component when a 4 Mbit density is required with high-speed Quad SPI support up to 133 MHz. It is suitable for applications needing uniform sector erase capabilities and robust data protection features. Consider the USON-8 package size constraints and the 2.7V to 3.6V operating voltage range during system power design.

Memory IC Part Context

This part belongs to the GD25Q40E/20E series, which offers uniform sector and block architecture. The series supports various packages including SOP8 and USON8. It is designed for general-purpose non-volatile storage with high endurance and long data retention characteristics typical of modern NOR flash technologies.

Memory IC Replacement Considerations

GD25Q40CTIGR: Similar 4Mbit capacity but uses SOP-8 package and 120 MHz speed. GD25Q40CEJGR: Similar 4Mbit capacity using USON-8 package but rated for industrial temperature (-40°C to +105°C) and 120 MHz speed.
