§Basic configuration

	Item	Specification

	USB standard	Specification Rev2.0 Full Speed

	Power supply	Bus power supply / Self-Power

	Device class	Vendor definition

	Interrupt (coordinate)	1ms
	transfer interval	1ms
	transfer interval

	End point buffer size	EP0: 8byte EP1: 5byte (EP0: control transfer, EP1: interrupt transfer)

§Connection with Host

Coordinate data, correction value or other various output data are all output to the host as a response to IN token. Output coordinate in coordinate data mode and correction data mode is output in the interrupt transfer, while other data is output to the host with control transfer.

	Host	TSC-30/IC
Buffer	Control transfer	End Point 0
Buffer	(Descriptor, Device Request (command))	IN/OUT
	(Descriptor, Device Request (command))	IN/OUT

Buffer	Interrupt transfer	End Point 1
	(Coordinate data)	IN

4-5. Panel ID setting (USB mode)

If two (three or four) touch screens to the same host are connected simultaneously, each TSC-30/IC to the host needs panel ID setting. This function is enabled in the USB mode, by setting pin number 58 (JP4) and pin number 59 (JP5) to “H” or “L”. Setting is enabled when hardware is reset, where Device Descriptor’s

iProduct is set to “0” or “1” and this value is identified by the		VCC
host as panel ID.	(TSC-30/IC)	VCC
