Web-Enabled ARM SBC Operates In Industrial Temperature Range

Based on Atmel’s AT91SAM9X25 processor, the iPAC-9X25 ARM embedded single-board computer (SBC) integrates 4 Gbytes of eMMC flash, 16 Mbytes of serial data flash, and 128 Mbytes of DDR RAM. EMAC’s Web-enabled SBC suits industrial embedded data-acquisition and control applications, as it operates in the temperature range of ‒40 to +85°C. It’s able to run an embedded server and display the current monitored or logged data. The SBC connects to the Web via two 10/100Base-T Ethernet ports or 802.11 wireless Wi-Fi networking when using the proper Linux modules and adapters. All connectors are brought out as headers on a board. The 3.77- by 3.54-in. iPAC-9X25 integrates one RS-232 serial port with full handshake (RTS/CTS/DTR/DSR/RI), two RS-232 serial ports (TX and RX only), and one RS-232/422/485 serial port with RTS/CTS handshake. Furthermore, there are two 10/100Base-T Ethernet ports, two USB 2.0 host ports, and one USB device port. Also included are up to seven channels of 10-bit A/D (0 to 3.3 V); an internal real-time clock/calendar; 21 GPIO (3.3 V) lines on header; eight high-drive, open-collector, dedicated digital output lines with configurable voltage tolerance; and two PWM I/O lines with an additional four PWM lines shared with A/D.
