can operate with low batteries or without batteries when connected to USB.
● Full USB compliance requirements are listed in the USB specification. However, in a camera designed
using this chipset, the following must at least be included: (a) an SDRAM with sufficiently low self-
refresh current, (b) USB inrush protection circuitry to maintain sufficient supply voltage to the 5V
sensor. See Section 7 for further details.
