• Manufacturer: Standard Microsystems (SMSC)

Specifications of LPC47M192-NW

• Lead Free Status / RoHS Status: Compliant

Notes :
Note 1: All leakage currents are measured with all pins in high impedance.
Note 2: The minimum value given for V
Note 3: Max I
Note 4: TUE (Total Unadjusted Error) includes Offset, Gain and Linearity errors of the ADC.
Note 5: Total Monitoring Cycle Time includes all temperature conversions, all analog input voltage conversions.
Note 6: The cycle time for option 1 is 542.336ms (typical) if 128 measurements are averaged for the remote diode
temperature reading and 8 measurements are averaged for all voltage and the internal temperature reading. It is
67.792ms (typical) for option 2 if 16 measurements are averaged for the remote diode temperature reading and a
single measurement is taken for all voltage and the internal temperature reading (i.e., no averaging).
Note 7: V
11.3.1 CAPACITANCE VALUES FOR PINS
The input and output capacitance applies to both the Super I/O Block and the Hardware Monitoring Block digital pins.
CAPACITANCE T
Note: The input capacitance of a port is measured at the connector pins.

Voltages are measured from the local ground potential, unless otherwise specified.
Typicals are at TA=25°C and represent most likely parametric norm.
The maximum allowable power dissipation at any temperature is PD = (TJmax - TA) / QJA.
Timing specifications are tested at the TTL logic levels, VIL=0.4V for a falling edge and VIH=2.4V for a rising
edge. TRI-STATE output voltage is forced to 1.4V.
