GD25Q20EEIGR

Memory IC Overview

The GD25Q20EEIGR is a 2M-bit (256K x 8) SPI NOR Flash memory manufactured by GigaDevice. It supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 133 MHz. The device features a uniform sector architecture with 4KB sectors and 32/64KB blocks. It operates on a single power supply voltage ranging from 2.7V to 3.6V. Key specifications include a typical page program time of 0.4ms, sector erase time of 45ms, and block erase times of 0.15s or 0.25s. Endurance is rated for a minimum of 100,000 program/erase cycles with 20-year data retention.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 532 Mbits/s in Quad I/O mode.
• Includes advanced security features such as 128-bit Unique ID, Serial Flash Discoverable Parameters (SFDP), and 2x1024-byte Security Registers with OTP locks.
• Provides software and hardware write protection mechanisms via Block Protect bits and the WP# pin.
• Features low power consumption with typical standby current of 11μA and deep power-down current of 1μA.

Memory IC Applications

• Code storage for embedded systems requiring Execute In Place (XiP) operation.
• Storage for firmware and boot code in consumer electronics and IoT devices.
• Data logging and configuration storage in industrial control applications.
• Parameter storage in network communication equipment.

Memory IC Procurement Notes

Verify the specific package type matches the design requirements, as the GD25Q20E series includes SOP8 and USON8 variants. Confirm that the ordering suffix corresponds to the desired packaging format. Ensure compatibility with the system's voltage levels and interface protocols before integration. Check for any specific environmental certifications required for the target application market.

Memory IC Selection Notes

Select this component when a 2M-bit capacity is sufficient for the application's code and data storage needs. Consider the USON8 package if space constraints are critical, otherwise use SOP8. Ensure the host controller supports the required SPI modes (Standard, Dual, or Quad) to leverage the high-speed read capabilities. Verify that the operating temperature range meets the environmental conditions of the final product.

Memory IC Part Context

The GD25Q20EEIGR belongs to the GD25Q20E family of Uniform Sector Dual and Quad Serial Flash memories. This series is designed for high-performance applications requiring reliable non-volatile storage. The 'EE' suffix typically denotes the USON8 package variant, distinguishing it from SOP8 versions like GD25Q20ESIGR. The family shares common electrical characteristics and command sets across different densities and packages.

Memory IC FAQ

What is the difference between the QE bit settings?

When the Quad Enable (QE) bit is set to 0, the WP# and HOLD# pins function as dedicated control inputs. When set to 1, these pins become bidirectional I/O pins (IO2 and IO3) to support Quad SPI operations.

How does the Hold function work?

The Hold function pauses serial communications without resetting the internal logic. It requires CS# to remain low and starts on the falling edge of the HOLD# signal while SCLK is low. The operation resumes on the rising edge of HOLD# when SCLK is low.
