Part 3.7: SD Card Slot

The SD card (Secure Digital Memory Card) is a memory card
based on the semiconductor flash memory process. It was
completed in 1999 by the Japanese Panasonic-led concept, and the
participants Toshiba and SanDisk of the United States conducted
substantial research and development. In 2000, these companies
launched the SD Association (Secure Digital Association), which has
a strong lineup and attracted a large number of vendors. These
include IBM, Microsoft, Motorola, NEC, Samsung, and others.
Driven by these leading manufacturers, SD cards have become the
most widely used memory card in consumer digital devices.
The SD card is a very common storage device. The extended
SD card supports SPI mode and SD mode. The SD card used is a
MicroSD card. The schematic diagram is shown in Figure 3-7-1.
