GD25Q40CTIGR in Macronix MX25 / GigaDevice GD25 SPI Flash Family
The GD25Q40CTIGR is part of GigaDevice's high-performance GD25Q series, a family of 4Mbit Serial NOR Flash memory chips designed to meet the rigorous demands of embedded systems. Utilizing a standard SPI interface with support for Dual and Quad I/O modes, these devices offer efficient data throughput for code shadowing and data storage. GigaDevice engineered this series to balance low power consumption with high reliability, making it a staple in consumer electronics and industrial applications.
Variants in This Sub-Family
Variants within the GD25Q40 sub-family primarily differ based on package type, voltage range, and temperature ratings. While the 'TIGR' suffix specifies an 8-SOP package and industrial temperature range, other variants may offer 8-WSON or 8-USON packages for smaller form factors. Some specialized versions operate at 1.8V for ultra-low-power battery applications, compared to the standard 3.3V power supply of the CTIGR variant.
