GD25LD40ETIGR

Memory IC Overview

The GD25LD40ETIGR is a 4M-bit Serial NOR Flash memory manufactured by GigaDevice. It features a uniform sector architecture with 512K x 8 organization and supports Standard SPI and Dual Output interfaces. The device operates on a single power supply voltage ranging from 1.65V to 2.0V, making it suitable for low-voltage applications. It offers a maximum clock frequency of 50MHz for fast read operations and up to 80Mbits/s for dual output data transfer. The component includes hardware and software write protection, security registers with OTP locks, and a 128-bit unique ID. It is available in SOP8 and USON8 packages.

Memory IC Feature Summary

• Supports Standard SPI and Dual Output modes for flexible data transfer rates
• Provides hardware and software write protection mechanisms including block protect bits
• Includes advanced security features such as 512-byte security registers with OTP locks
• Features a 128-bit unique identifier for each device

Memory IC Applications

• Low-power embedded systems requiring code storage
• Battery-operated consumer electronics
• IoT devices with strict voltage constraints
• Industrial control systems needing reliable non-volatile memory

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the 1.65V-2.0V voltage range variant. Confirm package type matches design requirements (SOP8 or USON8). Check moisture sensitivity level handling during assembly. Ensure compatibility with host controller SPI interface modes. Validate ordering quantity against manufacturer minimums.

Memory IC Selection Notes

Select this part when operating voltage is strictly between 1.65V and 2.0V. Consider Dual Output mode if higher throughput is needed within the 50MHz clock limit. Evaluate security register needs for application-specific data protection. Compare endurance and retention specs against system lifecycle requirements.

Memory IC Part Context

This component belongs to the GD25LD series, designed for ultra-low power applications. It complements other GigaDevice flash memories by offering a specific low-voltage option. The series targets markets where power efficiency is critical, such as wearable technology and portable medical devices.

Memory IC Replacement Considerations

GD25LD40CTIGR: Similar capacity but different voltage range (1.8V). GD25Q40ETIGR: Higher voltage range (2.7V-3.6V) and faster speed. Verify pinout and command set compatibility before substitution.
