This product is USB and communicate with the PC-based applications. This product is designed to be used with Microchip maXTouch touchscreen controllers. designed to be used with Microchip maXTouch touchscreen controllers. 2 2 The USB-I C-AUTO-PCB automatically adapts the voltage levels for SDA, The USB-I C-AUTO-PCB automatically adapts the voltage levels for SDA, SCL, /CHG, /RESET, DBG CLK, and DBG DATA signals depending on SCL, /CHG, /RESET, DBG CLK, and DBG DATA signals depending on the connected maXTouch device. The valid VDD levels for these signals the connected maXTouch device. The valid VDD levels for these signals are between 1.6V and 3.6V. are between 1.6V and 3.6V. The communication interface between the bridge IC and the target can be The communication interface between the bridge IC and the target can be either via the level shifter ICs or bypassing them: either via the level shifter ICs or bypassing them: Using Level shifter Using Level shifter VDD BRIDGE must be 5V VDD BRIDGE must be 5V R6 + R7 are placed R6 + R7 are placed R8 + R13 are DNF R8 + R13 are DNF LK3, LK5, LK6, LK7, LK8, LK9 are OPEN LK3, LK5, LK6, LK7, LK8, LK9 are OPEN Bypassing Level shifter Bypassing Level shifter VDD BRIDGE must be 3V VDD BRIDGE must be 3V R6 + R7 are DNF R6 + R7 are DNF R8 + R13 are placed R8 + R13 are placed LK3, LK5, LK6, LK7, LK8, LK9 are CLOSED LK3, LK5, LK6, LK7, LK8, LK9 are CLOSED In either case, power for the VDD rail must be supplied from the host.
