PIC24FJ256GB210 FAMILY
EQUATION 18-1: ESTIMATING USB TRANSCEIVER CURRENT CONSUMPTION
IXCVR =
40 mA ⢠VUSB ⢠PZERO ⢠PIN ⢠LCABLE
3.3V ⢠5m
+ IPULLUP
Legend: VUSB â Voltage applied to the VUSB pin in volts (3.0V to 3.6V).
PZERO â Percentage (in decimal) of the IN traffic bits sent by the PIC® microcontroller that are a value
of â0â.
PIN â Percentage (in decimal) of total bus bandwidth that is used for IN traffic.
LCABLE â Length (in meters) of the USB cable. The âUSB 2.0 OTG Specificationâ requires that
full-speed applications use cables no longer than 5m.
IPULLUP â Current which the nominal, 1.5 kï pull-up resistor (when enabled) must supply to the USB
cable.
