SG901-1047 Flexible Interface Wi-Fi Radio
Overview
Features
The SG901-1047 Kraken is an 802.11b/g WLAN
assembly which includes an 802.11 radio
designed for easy integration of 802.11 into
existing and new products with very little
development time. Kraken supports a variety of
interfaces for simple integration with most any
user product.
• Linux OS sources available to support
• Fully integrated FCC Certified 802.11 Solution
• Ready for customer application integration
• Control interface customization available
• Customer can develop their own interfaces to
their products.
• Variety of Standard Communications Interfaces
- 10/100Base-T (external magnetics)
- 3 UART ports (TTL Level)
- 2 USB ports – 1+1 Device/Host or 2 Host
- 1 SPI port
• GPIO and Peripherals
- I2S Digital Audio interface
- 8-bit camera interface
- Timer I/O
- Most serial and peripheral signals can be
used for GPIO if not otherwise employed
• 128Mbytes on board Flash
• 16Mbytes on board RAM
• Small, low-profile footprint
• Low Current consumption
• Fully compliant with IEEE 802.11b and g
WLAN standards
• Intelligent Power Control, Including 802.11
Power Save Mode
• RoHs Compliant
The SG901-1047 is a fully functional wireless
radio including a single-chip 802.11b/g
transceiver, an ARM9 processor, flash and
SDRAM memories, and a 10/100 Ethernet
combo. The system is shipped running Linux
with Wi-Fi ready for customer use. Application
software and OS changes are supported
through the Linux system source code provided
by Sagrad.
The on board 802.1 radio conforms to the IEEE
802.11b and 802.11g protocols operating in the
2.45GHz ISM frequency band supporting OFDM
data rates of 54, 48, 36, 24, 18, 12, 9, and
6Mbps. It also supports CCK data rates of 11
and 5.5Mbps and legacy data rates of 2 and
1Mbps.
Kraken connects to the user system through a
readily available 50-pin connector for power,
ground, and all peripheral signaling.
In addition to standard serial communications
interfaces, RS233, Ethernet, USB, SPI, I2C,
Kraken supports standard audio and camera
connections as well.
