GD25B64ENIGR

Memory IC Overview

The GD25B64ENIGR is a 64 Mbit Serial NOR Flash memory device manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 133 MHz under a 30 pF load. The device operates on a single power supply voltage ranging from 2.7 V to 3.6 V. It features a uniform sector architecture with 4 KByte sectors and 32/64 KByte blocks. The memory organization consists of 8M x 8 bits. The component is housed in an USON-8 package (3x4mm) and is designed for surface mount installation.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface operations for flexible data transfer rates.
• Includes software write protection mechanisms allowing top/bottom block protection and security register locking.
• Features advanced security capabilities including a 128-bit unique ID and Serial Flash Discoverable Parameters.
• Enables Execute In Place operation to reduce instruction fetch time and system latency.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring direct execution.
• Data logging and configuration storage in embedded systems.
• Firmware storage in consumer electronics and industrial control devices.

Memory IC Procurement Notes

Verify the specific package variant matches the design requirement, as the GD25B64E series includes SOP8, WSON8, and TFBGA options. Confirm the suffix 'ENIGR' corresponds to the USON-8 package and tape-and-reel delivery format specified in the ordering information section of the datasheet. Ensure compatibility with the 2.7V to 3.6V supply voltage range during system integration.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with uniform sector erase architecture is required. It is suitable for applications needing high-speed read performance up to 133 MHz via Quad I/O. Consider the USON-8 package size constraints and the single 3.3V nominal supply voltage. Verify that the software-based write protection meets the security requirements without additional hardware components.

Memory IC Part Context

The GD25B64ENIGR belongs to the GD25B64E family of Dual and Quad Serial Flash memories. This series is characterized by its uniform sector structure, which simplifies memory management compared to mixed sector architectures. The family supports various packages including SOP, USON, WSON, and BGA, catering to different space and thermal requirements in compact electronic designs.
