Operating Conditions Table 2.2 Operating Conditions PARAMETER SYMBOL CONDITIONS MIN MAX. UNIT Positive supply voltage for IC operation 1) VUIN DC parameter: VUINmin = VUOUTmin + VDROPmax VUINmax = VUOUTmax + VDROPmin 16 33.1 V Negative supply voltage V0V, VGND 0 0 V DC voltage at ASIP 2) VASIP Relative to V0V 16 33.1 V DC voltage at ASIN 2) VASIN Relative to V0V -4 4 V Operating current IUIN VUIN = 30V fc = 8.000 MHz; no load at any pin; transmitter turned off; digital State Machine is in idle state 6 mA Maximum output sink current at DO0, DO1, DO2, DO3, and DSR pins ICL1 10 mA Maximum output sink current at P0, P1, P2, P3, and PST pins ICL2 10 mA Ambient temperature range, operating range Ta ASI4U -25 85 °C ASI4U-E -25 105 °C ASI4U-F -40 85 °C 1) Below VUINmin, the power supply block might not be able to provide the specified output currents at UOUT and U5R. 2) Outside the maximum and minimum limits, the send current shape and send current amplitude cannot be guaranteed. Table 2.3 Crystal Frequency PARAMETER SYMBOL CONDITIONS NOMINAL UNIT Crystal frequency 1) fc 8.000/16.000 MHz 1) The IC automatically detects whether the crystal frequency is 8.000MHz or 16.000MHz and controls the internal clock circuit accordingly. The frequency detection is locked as soon as one AS-i telegram has been correctly received at any input channel. It can be reset by a power-on reset only. Note: In Slave Mode, the locking occurs if a Master Call has been received. In the Master, Repeater, or Monitor Modes, a Master Call or a Slave Response that has been received on any input channel triggers the frequency locking. The ASI4U/ASI4U-E/ASI4U-F supports an integrated clock watchdog. If no crystal or clock oscillation is recog- nized for 150µs, the IC generates a RESET event until clock oscillation is available. More detailed oscillator pin definitions can be found in section 4.10. 2.3. Quality Standards The quality of the ASI4U/ASI4U-E/ASI4U-F is ensured according to the IDT quality standards. Functional device parameters are valid for device operating conditions specified in section 2.2. Unless otherwise stated, production device tests are performed at Ta = +25°C within the recommended ranges of (VASIP - VASIN) and (VIN - V0V). Additional sample base testing is done at +85°C and -25°C (-40°C for the ASI4U-F). |
