â¢Operating current 75mA, maximum at +5 VDC. Typical power dissipation is 300mW at 5V
â¢Inrush current of up to 600mA for 50mS following power on
â¢Supply must be capable of sourcing 200 mA, minimum
â¢Total noise and ripple requirement must be less than 100 mV (p-p) for frequencies below 1 MHz, and less than 50 mV (p-p) for frequencies above 1 MHz
Serial Interface
â¢EIA 232E (Serial RS-232), DCE configuration. 8 Data Bits, 1 Stop Bit, No Parity, Full Duplex
â¢Hardware handshaking: RTS/CTS
â¢DSR is pulled HIGH (>+3V) by the 2701RSU when connected and powered. DTR can be asserted by the host to interrupt the flow of data from the controller
â¢Note that if the application does not monitor CTS, then an interval of approximately 5 seconds should be inserted between the issuance of a reset command and any other command
Baud Rate
â¢9600 (default) and 19200
USB Interface
â¢The CTR-270100-IT-RSU-00R controller is an interrupt-type, full-speed USB device
Operating Modes
â¢Full IntelliTouch SmartSet protocol
â¢Customer specific protocol
â¢Initial/ Stream/ Untouch Modes
Touch Resolution
â¢4096x4096, size independent
Conversion Time
â¢Approximately 10 ms per coordinate set
Reliability
â¢MTBF greater than 1,543,000 hours per MIL-HDBK-217-F2 using the parts stress calculation method for ground benign environment with an ambient temperature of 25°C
