GD25Q64CSJGR

Memory IC Overview

The GD25Q64CSJGR is a 64M-bit (8M x 8) serial 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 includes hardware and software write protection, a 128-bit unique ID, and security registers. The component is housed in an SOP-8 package and is rated for industrial temperatures ranging from -40°C to +105°C.

Memory IC Procurement Notes

Verify the specific suffix 'SJGR' against the manufacturer's official ordering guide to confirm package type and temperature range. Ensure compatibility with the host controller's Quad Enable (QE) bit requirements for high-speed operations. Confirm moisture sensitivity level handling during assembly.

Memory IC Selection Notes

Select this component when a 64M-bit capacity is required with industrial temperature stability. It is suitable for designs needing uniform sector erase capabilities and robust write protection mechanisms. Consider the SOP-8 footprint constraints and verify that the system voltage aligns with the 2.7V to 3.6V operating range.

Memory IC Part Context

Memory IC FAQ

How is the Quad Enable (QE) bit configured?

The QE bit is a non-volatile bit in the Status Register. Setting it to 1 enables Quad I/O operations on IO2 and IO3 pins, while setting it to 0 restores WP# and HOLD# functions.

What is the purpose of the Hold# pin?

The Hold# signal pauses serial communication without interrupting ongoing program or erase operations. It requires CS# to remain low and SCLK to be low to initiate the hold state.
