(GD25Q16 - 2MB SPI Flash in 8-Pin SOIC package)
개요
- 본 제품은 GD25Q16 2MB SPI 플래쉬 -8핀 SOIC 패키징입니다.
- SSD 하드드라이브의 미니어쳐 같은 메모리 칩으로 microSD 카드와 같은 대용량은 필요없지만 EEPROM과 같은 메모리는 너무 작을때 사용이 가능합니다.
- SPI 인터페이스를 가지고 있습니다.
특징

These little chips are like miniature SSD drives for your electronics. When you don't need something with as much storage as a micro SD card, but an EEPROM is too small, SPI (or QSPI) Flash chips give you on-the-order-of megabytes, with little cost and complexity. We use these chips all the time on our CircuitPython boards to let folks store code and assets like animations, fonts, images, configurations, audio clips, etc! A great way to add datalogging storage as well.
This chip has 2 MByte of non-volatile storage (16 mega-bits) and is well supported by CircuitPython and also our Arduino SPI Flash library. The standard SOIC size is fairly easy to solder, and it has the standard FLASH chip pinout so its good for just about any FLASH use including FPGAs or flash-less microcontrollers
You can also solder it onto the back of your QT Py board to add flash - note the QT Py will no longer be easily surface mounted as there'll be a lump on the bottom. You will need the customized CircuitPython build so it knows to look for the flash chip!
The Teensy 4.1 also can use an external FLASH chip there're pads on the bottom
