4D Systems Introduces Simple SD Storage for Microcontrollers
Taking memory burdens away from the host controller by allowing data transfers via a serial interface
This is a Press Release edited by StorageNewsletter.com on March 18, 2008 at 3:41 pmµDRIVE-uSD-G1
is a tiny module that can be easily interfaced to any microcontroller project
that requires “disk-drive” data storage. Most microcontroller application are
constrained by the available onboard memory where large volumes of data are
concerned. The compact 14.9 x 18.9 x 3.5mm
µDRIVE-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 RS-232 serial interface (300 to 256kbaud). The easy-learn
commands can read and write data blocks ranging from a single byte in size to
512 bytes of sectors on 64MB to 2GB SD memory cards.
Helpful on-board LEDs indicate
system status (GREEN: Power and Memory Card detect indicator; RED:
“Disk Drive” access) and µDRIVE-uSD-G1 can operate from 3.6 – 6.0 V at
about 25mA. An optional USB to Serial interface board μUSB-CE5 allows USB
connection for system firmware updates.
Applications for µDRIVE-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, µDRIVE-uSD-G1
offers an ideal, rapid solution, since it requires only a simple 5 pin interface
to the host device (VCC, TX, RX, GND, RESET).
µDRIVE-uSD-G1
is made in
Australia by 4D Systems and is available now from their USA distributor Saelig
Co. Inc.
