Features
A general purpose data storage device with a simple serial interface that can interface to
any microcontroller in a wide range of embedded applications.
Ideal companion peripheral that can be used like a “Disk Drive” for your next embedded
project.
Ideal for those applications that require Data Logging, Program Storage, Music files,
Image files, Video Clips or any general purpose raw Data Storage.
Onboard micro-SD (µSD) memory card adaptor that can accommodate 64Mb to 2Gig
memory cards. Memory cards can be purchased separately.
A handful of simplified commands provide reads and writes of data blocks from a single
byte in size to 512 bytes of sectors.
Extremely small size: 14.9 x 18.9 x 3.5mm.
Easy 5 pin interface to any host device: VCC, TX, RX, GND, RESET.
Onboard Leds indicate System Status:
-
GREEN
Led: Power and Memory Card detect indicator
-
RED
Led: “Disk Drive” data access indicator
Wide supply voltage range from 3.6 Volts to 6.0 Volts. Operating current @23mA
nominal when using a 5.0 Volts supply source. Note: Due to the characteristics of
some memory cards the module may require input voltages greater than 4.0 Volts.
Serial RS-232 (0 to 3.3 Volt signal levels) with auto-baud feature from 300 to 256K baud
rates. If interfacing to a system greater than 3.6 Volts supply, a series resistor (100 to
220 Ohms) maybe required on the RX line.
Powered by the 4D-LABS GOLDELOX processor (also available as separate OEM chips
for volume users).
Optional USB to Serial interface via the 4D micro-USB (µUSB-MB5 or µUSB-CE5)
modules for Personality-module-micro-Code (PmmC) system firmware updates.
