Module: DOSonCHIP-SD1
The DOSonCHIP™ SD/MMC Module integrates the CD17B10 silicon and SD/MMC socket onto a simple drop-in module that is easily added to your design. This module keeps a small 1.2" x 1.6" footprint by mounting the CD17B10 and its components under the SD/MMC socket. All the features of the CD17B10 are available.
Typical Applications
- Data Logging
- Mobile GPS Database Storage
- Audio/Video File Storage
- FPGA Configuration Storage
- Portable Consumer Electronics
- Toys
Innovative Features
- About the size of an SD/MMC socket (1.2" x 1.6")
- 0.1" spaced I/O pins for protoboard / header compatibility
- Integrated real-time clock for current date & time and file-stamping
- Future-proof with In-system firmware updates (via UART)
- Mounts under many SD/MMC sockets to further reduce PCB space
- Consumes only 5mA (typical) in active mode; < 0.1µA in shut down mode
