TSC-30/IC Product Specification 1. Products outline 1-1. Scope of Application This specification applies to the TSC-30/IC. 1-2. Outline TSC-30/IC is an analog touch screen control IC that performs A/D conversion on analog signal for the 4-wire, 5-wire and 8-wire resistive analog touch screen, and transmits coordination data with 10bit resolution to the host in a 9600bps serial (asynchronous) and USB. At the coordinate detection, internal filtering process provides a stabilized coordinate value.
