Module embeds memory
cards in MCU projects
A few simple commands provide direct access to the onboard micro-SD memory card for handling almost any size or type of binary data
The uDrive-uSD-G1 is a tiny module that can be easily interfaced to any microcontroller project that requires 'disk-drive' data storage. Most microcontroller applications are constrained by the available onboard memory where large volumes of data are concerned. The compact 14.9 x 18.9 x 3.5mm uDrive-uSD-G1 takes memory burdens away from the host controller by allowing data transfers via a simple serial interface.

A few simple commands provide direct access to the onboard micro-SD memory card for handling almost any size or type of binary data.
Data storage and retrieval takes place via the auto-baud RS232 serial interface (300 to 256Kbaud).
The easy-learn commands can read and write data blocks ranging from a single byte to 512byte of sectors on 64Mbyte to 2Gbyte SD memory cards.
Helpful onboard LEDs indicate system status (green for the power and memory card detect indicator; red for 'disk drive' access) and uDrive-uSD-G1 can operate from 3.6 to 6.0V, drawing about 25mA.
An optional USB to serial interface board, theUSB-CE5, allows USB connection for system firmware updates.
Applications for uDrive-uSD-G1 include data logging, program storage, music/image/video files, or any general purpose data storage.
When a PIC, AVR, ARM, STAMP, Propeller or any other microcontroller application requires data storage, uDrive-uSD- G1 offers an ideal, rapid solution, as it requires only a simple 5-pin interface to the host device (VCC, TX, RX, GND, reset).
The uDrive-uSD-G1 is made in Australia by 4D Systems and is available now from Saelig at US $37.00.
