5 / 70 page 5/70 ST62T15C/T25C/E25C 1.2 PIN DESCRIPTIONS VDD and VSS. Power is supplied to the MCU via these two pins. VDD is the power connection and VSS is the ground connection. OSCin and OSCout. These pins are internally connected to the on-chip oscillator circuit. A quartz crystal, a ceramic resonator or an external clock signal can be connected between these two pins. The OSCin pin is the input pin, the OSCout pin is the output pin. RESET. The active-low RESET pin is used to re- start the microcontroller. Internal pull-up is provid- ed at this pin. TEST/V PP. The TEST must be held at VSS for nor- mal operation. If TEST pin is connected to a +12.5V level during the reset phase, the EPROM programming Mode is entered. NMI. The NMI pin provides the capability for asyn- chronous interruption, by applying an external non maskable interrupt to the MCU. The NMI input is falling edge sensitive. The user can select as op- tion the availability of an on-chip pull-up at this pin. TIMER. This is the timer I/O pin. In input mode it is connected to the prescaler and acts as external timer clock input or as control gate input for the in- ternal timer clock. In output mode the timer pin out- puts the data bit when a time-out occurs. The user can select as option the availability of an on-chip pull-up at this pin. PA0-PA7. These 8 lines are organized as one I/O port (A). Each line may be configured under soft- ware control as inputs with or without internal pull- up resistors, interrupt generating inputs with pull- up resistors, open-drain or push-pull outputs. PA0- PA3 can also sink 20mA for direct LED driving while PA4-PA7 can be programmed as analog in- puts for the A/D converter. PB0-PB7. These 8 lines are organized as one I/O port (B). Each line may be configured under soft- ware control as inputs with or without internal pull- up resistors, interrupt generating inputs with pull- up resistors, open-drain or push-pull outputs, or as analog inputs for the A/D converter. PC4-PC7. These 4 lines are organized as one I/O port (C). Each line may be configured under soft- ware control as inputs with or without internal pull- up resistors, interrupt generating inputs with pull- up resistors, open-drain or push-pull outputs, or as analog inputs for the A/D converter.
