GD25Q40ESIGR

Memory IC Overview

The GD25Q40ESIGR is a 4 Mbit Serial NOR Flash memory manufactured by GigaDevice, housed in an SOP-8 package. It operates on a single 2.7 V to 3.6 V power supply and supports standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 133 MHz. The device features uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. It includes hardware and software write protection, a 128-bit unique ID, security registers, and supports Execute In Place (XiP) operations.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes for flexible data transfer rates up to 532 Mbits/s.
• Provides comprehensive data protection via software block protect bits and hardware WP# pin control.
• Enables Execute In Place (XiP) operation with continuous read capabilities to reduce instruction fetch latency.
• Includes advanced security features such as a 128-bit Unique ID and programmable security registers.

Memory IC Applications

• Code storage for microcontrollers and system-on-chip (SoC) devices
• Firmware and boot code storage in embedded systems
• Parameter and configuration data storage in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'IGR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering documentation matches the SOP-8 physical dimensions specified in the package information section. Cross-reference the part number with the valid ordering list to confirm current production status.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity is required with high-speed Quad SPI interface support. It is suitable for designs needing uniform sector erase capabilities and robust write protection mechanisms. Consider the SOP-8 package constraints and the 2.7 V to 3.6 V voltage range compatibility with the target system logic levels.

Memory IC Part Context

This part belongs to the GD25Q40E series of uniform sector serial flash memories. The series is designed for general-purpose non-volatile storage applications requiring high reliability and fast access times. The GD25Q40E variant specifically offers 4 Mbit density, distinguishing it from lower-density options like the GD25Q20E within the same family.
