TSC-40/IC Product Specification 1. PRODUCTS OUTLINE 1-1. Scope of Application This specification applies to the TSC-40/IC. 1-2. Outline TSC-40/IC is an analog touch screen control IC that performs A/D conversion on analog signal for the 4-wire and 5-wire resistive analog touch screen, and transmits coordination data with 10bit resolution to the host in a 9600bps serial (asynchronous). The serial communication enables a connection with PC’s serial port via RS-232C I/F circuit or TTL le

TSC-40/IC Product Specification *1: Auto transition = Mode changes by a command are not performed. It becomes a “Coordinate Data Mode (150pps)” immediately after reset. *2: Always open. If connected with VCC, VSS, or other circuit, an error operation may occur. *3: About pin number 14, 15 and 16, immediately after a power supply injection, it works as an input terminal and becomes an output terminal after that. Do not open these terminals. *4: If neither SW0 nor SW1 function is used, conn
