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/VPP. 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.
PA1-PA3. These 3 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. PA1-
PA3 can also sink 20mA for direct LED driving.
PB0..PB1,PB3,PB5-PB7. These 6 lines are or-
ganized as one I/O port (B). Each line may be con-
figured under software control as inputs with or
without internal pull-up resistors, interrupt generat-
ing inputs with pull-up resistors, open-drain or
push-pull outputs. PB3,PB5..-PB7 can be used as
analog inputs for the A/D converter on the
ST62T00C, T01C and E01C.

PROGRAMMING MODES (Cont’d)
1.4.2 Program Memory
EPROM/OTP programming mode is set by a
+12.5V voltage applied to the TEST/VPP pin. The
programming flow of the ST62T00C,T01C,T03C
and E01C is described in the User Manual of the
EPROM Programming Board.

1.4.3 EPROM Erasing
The EPROM of the windowed package of the
MCUs may be erased by exposure to Ultra Violet
light. The erasure characteristic of the MCUs is
such that erasure begins when the memory is ex-
posed to light with a wave lengths shorter than ap-
proximately 4000Å. It should be noted that sun-
lights and some types of fluorescent lamps have
wavelengths in the range 3000-4000Å.
It is thus recommended that the window of the
MCUs packages be covered by an opaque label to
prevent unintentional erasure problems when test-
ing the application in such an environment.
The recommended erasure procedure of the
MCUs EPROM is the exposure to short wave ul-
traviolet light which have a wave-length 2537A.
The integrated dose (i.e. U.V. intensity x exposure
time) for erasure should be a minimum of 30W-
sec/cm2. The erasure time with this dosage is ap-
proximately 30 to 40 minutes using an ultraviolet
lamp with 12000µW/cm2 power rating. The
ST62E01C should be placed within 2.5cm (1Inch)
of the lamp tubes during erasure.
