GD25Q32CSJGR

Memory IC Overview

The GD25Q32CSJGR is a 32M-bit NOR flash memory manufactured by GigaDevice. It operates within a voltage range of 2.7V to 3.6V and supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 120MHz. The device features a 4M x 8 organization and utilizes an SOP-8 (208mil) package. It is rated for industrial temperatures from -40°C to +105°C and is supplied in tape and reel packaging.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI communication protocols for flexible data transfer rates.
• Includes hardware and software write protection mechanisms via the WP# pin and status register bits.
• Features uniform sector and block architecture allowing granular erase operations.
• Provides execute-in-place capability for direct code execution from the memory.

Memory IC Applications

• Firmware storage for microcontrollers and system-on-chip devices
• Code storage for embedded systems requiring boot functionality
• Data logging applications in industrial environments

Memory IC Procurement Notes

Verify the specific suffix 'J' confirms the SOP-8 208mil package and industrial temperature grade (-40°C to +105°C). Confirm the 'T&R' designation indicates tape and reel packaging rather than tube or cut tape. Ensure compatibility with the host controller's SPI mode and voltage levels before integration.

Memory IC Selection Notes

Select this component when a 32M-bit capacity is required with industrial temperature resilience. The SOP-8 208mil package suits designs needing wider pitch for assembly. Consider the 120MHz speed limit and Quad I/O support if high throughput is necessary. Verify that the power supply constraints align with the 2.7V to 3.6V operating range.

Memory IC Part Context

This part belongs to the GD25Q32C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. The series offers various package options including SOP, WSON, and USON variants. The CSJGR suffix specifically denotes the industrial temperature range and surface-mount SOP-8 packaging configuration.

Memory IC Replacement Considerations

GD25Q32CSIGR: Same capacity and interface but rated for commercial temperature range (-40°C to +85°C) instead of industrial.

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 IO2 and IO3 respectively.

How does the Hold function behave during operation?

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