1.3 Pin Description
V
DD
,
V
SS
,
V
DDA
, GNDA, V
PP
.
In order to avoid
noise disturbances, the power supply of the digital
part is kept separate from the power supply of the
analog part.
V
DD.
Main Power Supply Voltage (5V
±
10%).
In the ST52x410 version the two V
DD
pins must be
connected togheter.
V
SS
. Digital circuit ground.
In the ST52x410 version the two V
SS
pins must be
connected togheter.
V
DDA
. Analog V
DD
of the Analog to Digital
Converter.
GNDA
. Analog V
SS
of the Analog to Digital
Converter.
Must be tied to V
SS
.
V
PP
. Main Power Supply for internal EPROM
(12.5V
±
5%, in programming phase) and Operating
MODE selector. During the Programming phase
(programming), V
PP
must be set at 12V. In the
Working phase V
PP
must be equal to
V
SS
.
OSCin
and
OSCout.
These pins are internally
connected with the on-chip oscillator circuit. A
quartz crystal or a ceramic resonator can be
connected between these two pins in order to allow
the correct operations of ST52T410/ST52x420
with various stability/cost trade-off. An external
clock signal can be applied to OSCin, in this case
OSCout must be floating.
RESET
. This signal is used to restart ST52T410/
ST52x420 at the beginning of its program and to
select the program mode for EPROM.
Ain0-Ain7.
These 8 lines are connected to the
input of the analog multiplexer. They allow the
acquisition of 8 analog input (ST52x420 only).
During the Programming phase, Ain0, Ain1, Ain2
and Ain3 are used to manage EPROM operation.
PA0-PA7, PB0-PB7, PC0-PC3
. These lines are
organized as I/O port. Each pin can be configured
as input or output. PA7/PB7 are tied to the same
output. During Programming phase PA port is used
for EPROM read/write data.
T0RES
,
T0CLK
,
T0STRT
. These pins are related
with the internal Programmable Timer/PWM 0.
This Timer can be reset externally by using
T0RES. In Working Mode, T0RES resets the
address counter of the Timer. T0RES is active at
low level.
The Timer 0 Clock can be the internal clock or can
be supplied externally by using pin T0CLK.
An external Start/Stop signal can be used to
control the Timer through T0STRT pin.
T0OUT, T1OUT, T2OUT.
The TIMER/PWM
outputs are available on these pins.
T0OUT
,
T1OUT
,
T2OUT
. The TIMER/PWM
complementary outputs are available on these
pins.
TEST
.
During the Programming and Working
phase it
must
be set to Vss
.
INT
. This pin is used to start the External Interrupt
routine.
