29 / 43 page ![]() SCA3000 Series VTI Technologies Oy 29/ 43 www.vti.fi Doc.Nr. 8257300A.07 Rev.A.07 5 Electrical Characteristics All voltages are reference to ground. Currents flowing into the circuit have positive values. 5.1 Absolute maximum ratings The absolute maximum ratings of the SCA3000 are presented in Table 15 below. Table 15. Absolute maximum ratings of the SCA3000 Parameter Value Unit Supply voltage (Vdd) -0.3 to +3.6 V Voltage at input / output pins -0.3 to (Vdd + 0.3) V ESD (Human body model) ±2 kV Storage temperature -40 ... +125 °C Storage / operating temperature -40 ... +85 °C Mechanical shock * > 10 000 g Ultrasonic cleaning Not allowed * 1 m drop on concrete may cause >>10000 g shock. ULTRASONIC AGITATION NOT ALLOWED. 5.2 Power Supply Please refer to the corresponding product datasheet. 5.3 Digital I/O Specification 5.3.1 Digital I/O DC characteristics Table 16. DC characteristics of digital I/O pins. No. Parameter Conditions Symbol Min Typ Max Unit Input: CSB, MOSI, Xreset, SCK_SCL has no pull up / pull down 1 Pull up current: CSB VIN = 0 V IPU 10 50 µA 2 Pull down current: MOSI VIN = Dvio IPD 10 50 µA 3 Pull up current Xreset VIN = 0 V IPU 3 10 µA 4 Input high voltage VIH 0.7*Dvio V 5 Input low voltage VIL 0.3*Dvio V 6 Hysteresis VHYST 0.1*Dvio V Output terminal: MISO_SDA, INT 7 Output high voltage I > -4 mA VOH 0.8*Dvio Dvio V 8 Output low voltage I < 4 mA VOL 0 0.2*Dvio V 9 Tristate leakage 0 < VMISO < 2.7 V ILEAK -2 2 µA 5.3.2 Digital I/O level shifter All the SCA3000 products have an internal level shifter that can be used to interface e.g. a micro controller using lower supply than the SCA3000. The level shifter is "programmed" by providing the supply voltage of the interfaced device to the DVIO-pin. Please refer to the corresponding product data sheet for details. |
