GENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
The SSD (Safety Secure Digital) and SSDIO (Safety Secure Digital I/O) are storage media compliant
with the SD standard Rev 1.01. The SD is a low-cost mass storage device implemented as a removable
card, very small and easy to move from one device to another with high performance in terms of read
and write capabilities. The SD are commonly used on audio and video consumer electronic devices due
to the high speed transfer rate and at their compactness/thickness: 2.1 mm for the normal and 1.4 mm
for the thin version.
On SSD and SSDIO Oberon implemented a serial interface in order to connect it to external devices,
keeping the SD specifications; the products are designed around Hyperstone’s S2-16X flash Memory
Controller, while the serial communication is handled by a UART 8051 processor. The products comes
with a library of API in order to write and integrate the custom application in a simple way.

Serial and I/O FeaturesSerial and I/O Features
The Oberon SD has the capability to communicate with devices using RS232 or driving/reading sensors
using 2 DIGITAL I/O pins.
The RS232 communication is configurable from 2400bps up-to 57600bps, while the communications
parameters are fixed to N81.
The 2 digital I/O pins are configurable as Input or Output and it is possible to drive them individually.
The Safety feature can be implemented as well.

THEORY OF OPERATIONTHEORY OF OPERATION
The flash storage sector 0 (first 512byte) is virtually
virtually used as R/W channel to drive the 8051
virtuallyvirtually
communication controller. The firmware running on the SD controller manages data received and
transmitted during Read/Write commands issues by the host. A special filter is performing real write
and read to storage device and virtual RS232 commands, to perform communications to/from serial
devices.
Those commands, useful to communicate with serial devices, are simply performed reading and writing
data on Sector 0 of the Oberon SD.

The following example shows how to perform those commands in Unix
environment using C language:
/* Open the SD device */
int f = open("/dev/sd1", O_RDWR| O_DIRECT);
/* Positioning at sector 0 (not necessary at first opening)*/
lseek(f, 0, SEEK_SET);
/* Write to SSD device */
write(f, "Command or data to send to SD....", ...);
/* Repositioning at sector 0 */
lseek(f, 0, SEEK_SET);
/* Read data back from SD device*/
read(f, "data back from SD....", ...);
/* Closing device */
close(f);
