ST62T45B/E45B
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.
www.DataSheet4U.com
RESET. The active-low RESET pin is used to re-
start the microcontroller.
TEST/VPP. The TEST must be held at VSS for nor-
mal operation (an internal pull-down resistor se-
lects normal operating mode if TEST pin is not
connected). If TEST pin is connected to a +12.5V
level during the reset phase, the EPROM/OTP
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 with Schmitt trigger charac-
teristics. The user can select as option the availa-
bility of an on-chip pull-up at this pin.
PA5-PA7. These 3 lines are organised as one I/O
port (A). Each line may be configured under soft-
ware control as input with or without internal pull-
up resistors, input with interrupt generation and
pull-up resistor, open-drain or push-pull output, or
as analog input for the A/D converter.
PB0...PB7. These 8 lines are organised as one
I/O port (B). Each line may be configured under
software control as input with or without internal
pull-up resistors, input with interrupt generation
and pull-up resistor, open-drain or push-pull
output, analog input for the A/D converter.
PB0..PB3 can be used as analog inputs for the
A/D converter , while PB7/Sout, PB6/Sin and
PB5/Scl can be used respectively as data out,
data in and Clock pins for the on-chip SPI. In addi-
tion, PB4..PB7 can sink 20mA for direct LED or
TRIAC drive.
PC0-PC7. These 8 lines are organised as one I/O
port (C). Each line may be configured under soft-
ware control as input with or without internal pull-
up resistor, input with interrupt generation and
pull-up resistor, open-drain or push-pull output, or
as LCD segment output S33..S40.
COM1-COM4. These four pins are the LCD pe-
ripheral common outputs. They are the outputs of
the on-chip backplane voltage generator which is
used for multiplexing the 45 LCD lines allowing up
to 180 segments to be driven.
S17..S40. These pins are the 24 LCD peripheral
segment outputs. S33..S40 are alternate functions
of the Port C I/O pins. (Combiports feature)
VLCD. Display voltage supply. It determines the
high voltage level on COM1-COM4 and S4-S48
pins.
VLCD1/3, VLCD2/3. Display supply voltage inputs
for determining the display voltage levels on
COM1-COM4 and S4-S48 pins during multiplex
operation.
OSC32in and OSC32out. These pins are inter-
nally connected with the on-chip 32kHz oscillator
circuit. A 32.768kHz quartz crystal can be con-
nected between these two pins if it is necessary to
provide the LCD stand-by clock and real time in-
terrupt. OSC32in is the input pin, OSC32out is the
output pin.
TIMER. This is the TIMER 1 I/O pin. In input
mode, it is connected to the prescaler and acts as
external timer clock or as control gate for the in-
ternal timer clock. In output mode, the TIMER pin
outputs 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.
