Wearable Inc. announces its first DOSonCHIP™ product, the CD17B10—the lowest cost way to add PC compatible removable mass data storage to your products. Costing as low as $5 per unit, engineers can quickly add a miniSD/SD/MMC card with a FAT file system to their design. It consumes a scant 5mA while running, less than 0.1µA in shutdown, is only 4mm x 4mm in size, and requires a minimum of 2 external capacitors (optionally add 1 watch crystal & 3 more passives for time & date real-time clock). It interfaces to any microcontroller by way of a UART (with autobaud detection), SPI bus, or I2C bus (planned) (all I/O lines are 5V tolerant). It is also RoHS (Pb-free) compliant.
