GD25Q40CTIGR
Overview
The GD25Q40CTIGR is a 4Mbit Serial NOR Flash memory featuring Support for Standard, Dual, and Quad SPI interfaces. Operating at up to 104 MHz, this IC provides high-speed data throughput and features Execute-in-Place (XIP) capabilities for code execution directly from memory. It is designed for 2.7V to 3.6V operation with an emphasis on low power consumption, including a 1uA standby current and a Deep Power-Down mode.
Why Choose This Part
This memory offers Quad I/O performance to maximize bandwidth while maintaining a small SOP8 footprint. It includes hardware and software write protection for data integrity and high reliability with a 20-year data retention specification. The inclusion of four 256-byte security registers with OTP locks allows for secure storage of sensitive identification data.
Applications
Getting Started
Integration requires a standard SPI master controller capable of Mode 0 or Mode 3 communication at 3.3V logic levels. Most modern microcontroller HALs support the standard JEDEC SFDP register for automatic discovery of memory parameters. For prototyping, the 150mil SOP8 package can be used with standard SOIC-8 to DIP adapters.
