GD25Q32CHIGR

Memory IC Overview

The GD25Q32CHIGR is a 32M-bit (4M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single 2.7V to 3.6V power supply and supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 120 MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It is housed in an USON-8 package measuring 3x3mm and is rated for industrial temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface modes for flexible data transfer rates.
• Features software and hardware write protection mechanisms including block protect bits and WP# pin control.
• Includes advanced security capabilities such as a unique ID and programmable security registers with OTP locks.

Memory IC Applications

• Industrial embedded systems requiring reliable non-volatile storage
• Consumer electronics firmware storage
• IoT devices utilizing low-power serial flash memory

Memory IC Procurement Notes

Verify the specific ordering suffix 'IGR' confirms the USON-8 (3x3mm) package and tape-and-reel delivery format. Confirm the component status is acceptable for your design lifecycle, as related variants may carry NRND status. Ensure voltage and temperature ratings match your system requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact USON-8 footprint is required for 32M-bit storage. It is suitable for designs needing industrial temperature stability and support for high-speed Quad SPI operations. Verify that the host controller supports the necessary command sets for dual and quad I/O access.

Memory IC Part Context

This part belongs to the GD25Q32C series of 3.3V uniform sector serial flash memories. It shares architectural similarities with other members of the family but is distinguished by its specific USON-8 package and reel packaging configuration intended for automated surface-mount assembly processes.

Memory IC FAQ

What is the function of the QE bit in the Status Register?

The Quad Enable (QE) bit allows the device to operate in Quad SPI mode. When set to 1, pins WP# and HOLD# function as bidirectional I/O pins IO2 and IO3.

How does the Hold function behave when QE is enabled?

When the QE bit is set to 1, the Hold function is disabled, and the HOLD# pin acts as a dedicated data I/O pin rather than a hold input.
