GD25D80CSIGR

Memory IC Overview

The GD25D80CSIGR is an 8 Mbit (1M x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 2.7 V to 3.6 V. The device supports standard SPI and Dual Output interfaces, with a maximum clock frequency of 100 MHz for fast read operations under a 30 pF load. It features a uniform sector architecture consisting of 4 K-byte sectors and 32/64 K-byte blocks. The memory organization allows for page programming of up to 256 bytes per page.

Memory IC Feature Summary

• Supports Standard SPI and Dual Output data transfer modes
• Features software and hardware write protection mechanisms
• Includes a 128-bit unique identifier for each device
• Provides flexible uniform sector and block erase architectures

Memory IC Applications

• Code storage for microcontrollers
• BIOS firmware storage
• XIP (Execute In Place) applications
• Consumer electronics firmware

Memory IC Procurement Notes

Verify the specific package variant required, as the GD25D80C series is available in SOP8, TSSOP8, and USON8 configurations. Confirm that the system design accommodates the 2.7V to 3.6V operating voltage range. Ensure compatibility with standard SPI mode 0 and 3 protocols. Check for any specific automotive or industrial grade requirements if applicable, as this part number typically denotes standard commercial grade.

Memory IC Selection Notes

Select this component when a cost-effective 8 Mbit non-volatile storage solution is needed for code execution or data logging. It is suitable for designs requiring dual I/O speed improvements over standard SPI without the complexity of quad interfaces. Consider the uniform sector size for easy file system implementation. Verify that the 100 MHz clock speed meets the throughput requirements of the host processor.

Memory IC Part Context

The GD25D80C belongs to GigaDevice's family of 3.3V uniform sector serial flash memories. This series is designed to provide high reliability and performance for embedded applications. The GD25D80CSIGR specifically utilizes the SOP8 or similar 8-lead package format, distinguishing it from other density variants or package options within the broader GD25DxxCKIGR or GD25WD80C families.

Memory IC FAQ

What is the difference between Standard SPI and Dual Output modes?

Standard SPI uses separate pins for input (SI) and output (SO), while Dual Output mode utilizes both SI and SO pins bidirectionally to transfer data at twice the rate.

How is write protection implemented in the GD25D80C?

Write protection is achieved through software commands setting Block Protect bits in the status register, or via hardware control using the WP# pin combined with the SRP bit.
