ST6294
GENERAL DESCRIPTION
The ST6294 microcontroller is member of the 8-bit
HCMOS ST62xx family, a series of devices oriented
to low-medium complexity applications. All ST62xx
members are based on a building block approach: a
common core is surrounded by a combination of on-
chip peripherals (macrocells).
The macrocells of the ST6294 are: the Timer pe-
ripheral that includes an 8-bit counter with a 7-bit
software programmable prescaler (Timer1), the 8-
bit Auto-reload Timer with 7 bit programmable
prescaler (AR Timer), the 8-bit A/D Converter with
up to 13 analog inputs (A/D inputs are alternate
functions of I/O pins), the Digital Watchdog (DWD)
and an 8-bit Serial synchronous Peripheral Inter-
face (SPI). In addition, these devices offer 128
bytes of EEPROM for non volatile data storage.
The ST6294 is a version of the ST6265 specifically
tailored to be used in telephone set applications.
The only difference is that a CKOUT pin is provided
instead of the NMI pin. For this reason this
datasheet only contains information relating to the
differences to the ST6265, and thus should be read
in conjunction with the ST6265 datasheet. The
ST62E94 EPROM version is available for prototypes
and low-volume production; also OTP version is
available.
PIN DESCRIPTION
VDD and VSS. Power is supplied to the MCU using
these two pins. VDD is power and VSS is the ground
connection.
OSCin and OSCout. These pins are internally
connected with the on-chip oscillator circuit. A
quartz crystal, a ceramic resonator or an external
clock signal can be connected between these two
pins in order to allow the correct operation of the
MCU with various stability/cost trade-offs. The fre-
quency at OSCin and OSCout is internally divided
by 1, 2 or 4 by a software controlled divider.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 to the beginning of its pro-
gram.
TEST. The TEST must be held at VSS for normal
operation (an internal pull-down resistor selects
normal operating mode if TEST pin is not con-
nected).
CKOUT. This clock pin outputs the oscillator fre-
quency divided by 2 (fOSC/2). This function can be
disabled by software to reduce power consump-
tion.
PC1/TIM1/Ain. This pin can be used as a Port C
I/O bit, as Timer 1 I/O pin or as analog input for the
on-chip A/D converter. If programmed to be the
Timer 1 pin, in input mode it is connected to the
prescaler and acts as external timer clock or as
control gate for the internal timer clock. In the out-
put mode the timer pin outputs the data bit when a
time out occurs.
To use this pin as Timer 1 output a dedicated bit in
the TIMER 1 Status/Control Register must be set.
To use this pin as input pin the I/O pin has to be
programmed as input. The analog mode should be
programmed to use the line as an analog input.
PB6/ARTIMin, PB7/ARTIMout. These pins are
either Port B I/O bits or the Input and Output pins of
the Auto-reload Timer. To be used as timer input
function PB6 has to be programmed as input with
or without pull-up. A dedicated bit in the AR TIMER
Mode Control Register sets PB7 as timer output
function.
PA0-PA7. These 8 lines are organized as one I/O
port (A). Each line may be configured under soft-
ware control as input with or without internal pull-
up resistor, interrupt generating input with pull-up
resistor, analog input, open-drain or push-pull out-
put.
PB0-PB3, PB4, PB5. These 6 lines are organized
as one I/O port (B). Each line may be configured
under software control as input with or without in-
ternal pull-up resistor, interrupt generating input
with pull-up resistor, open-drain or push-pull out-
put. In output mode these lines can also sink 20mA
for direct LED and TRIAC driving. The reset con-
figuration of PB0-PB3 can be selected by mask op-
tion (pull-up or high impedance).
PC0-PC4. These 5 lines are organized as one I/O
port (C). Each line may be configured under soft-
ware control as input with or without internal pull-
up resistor, interrupt generating input with pull-up
resistor, analog input for the A/D converter, open-
drain or push-pull output. PC2-PC4 can also be
used as respectively Data in, Data out and Clock
I/O pins for the on-chip SPI to carry the synchro-
nous serial I/O signals.

Notes :
1. A current of ± 5mA can be forced on each pin of the digital section without affecting the functional behaviour of the device. For a positive
current injected into one pin, a part of this current (10%) can be expected to flow from the neighbouring pins.
2. If a total current of +1 mA is flowing into the single analog channel or if the total current flowing into all the analog inputs is of 1mA, all the
resulting conversions are shifted by +1 LSB. If a total positive current is flowing into the single analog channel or if the total current
flowing into all the analog inputs is of 5mA, all the resulting conversions are shifted by +2 LSB.
3. An oscillator frequency above 1MHz is recommended for reliable A/D results.
