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 level.

TSC-40/IC Product Specification 3. Pin functions Pin number Pin name I/O 1 AN2 I/O Touch screen XL/UR input pin. 2 AN3 I/O Touch screen XR/LL input pin. 3 SEL1 I Transition select pin. H = Auto transition*1 after reset. L = transition by command. 4 EEP-DO I EEPROM DO input pin; At using no EEPROM, Vcc or GND is connected. 5 VREF I A/D converter reference voltage input pin; Vcc is connected. 6 RST I Reset input pin (active L).
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.
TSC-40/IC Product Specification 4. Initial setting 4-1. EEPROM setting Depending on that calibration is performed in either TSC-40/IC or host, you can select whether EEPROM is used or not to store the correction data. EEPROM selection can be set via pin number 16, where hardware reset release enables the setting. (TSC-40/IC) VCC (EEPROM) H= Not used SEL4/EEP-CS L= Used CS 4-2. Touch screen mode setting Touch screen mode setting for 4-wire/5-wire is performed by setting pin number 15 to “H” or “L”.

TSC-40/IC Product Specification 6. Packaging Specification 6-1. Outline With a basic packaging unit of 2000, TSC-40/IC is packaged for the number of 2000 and its multiple using damp-proof aluminum laminate bags (Basic packaging). If the delivery quantity is less than 2000 or not multiple of 2000, or the product can not be packaged with a unit of 2000, then no damp-proof packaging specification is applicable (Small group packaging). If packaged with small group packaging, the products may be dampened.
