PCF2103 family

Pin functions; note 1
Note
1.
When the I
2
C-bus is used, the parallel interface pin E must be defined as E = 0. In I
2
C-bus read mode DB7 to DB0
should be connected to V
DD
or left open-circuit.
a) When the parallel bus is used, pins SCL and SDA must be connected to V
SS
or V
DD
; they may not be left
unconnected.
b) If the 4-bit interface is used without reading out from the PCF2103 (i.e. R/W is set permanently to logic 0), the
unused ports DB0 to DB3 can either be set to V
SS
or V
DD
instead of leaving them open.
NAME
FUNCTION
DESCRIPTION
RS
register select
RS selects the register to be accessed for read and write; there is an internal pull-up
on this pin
RS = 0 selects the instruction register for write and the busy flag and address
counter for read
RS = 1 selects the data register for both read and write
R/W selects either the read (R/W = 1) or write (R/W = 0) operation; there is an
internal pull-up on this pin
pin E is set HIGH to signal the start of a read or write operation; data is clocked in or
out of the chip on the negative edge of the clock
the bi-directional, 3-state data bus transfers data between the system controller and
the PCF2103; DB7 may be used as the busy flag, signalling that internal operations
are not yet completed; in 4-bit operations the 4 higher order lines DB7 to DB4 are
used; DB3 to DB0 must be left open-circuit; there is an internal pull-up on each of the
data lines
these pins output the data for columns

LCD power
supply
oscillator
R1 to R18
these pins output the row select waveforms to the display; R17 and R18 drive the
icons
positive power supply for the liquid crystal display
V
LCD
OSC
when the on-chip oscillator is used this pin must be connected to V
DD
; an external
clock signal, if used, is input at this pin
input for the I
2
C-bus clock signal
I/O for the I
2
C-bus data line
the hardware sub-address line is used to program the device sub-address for two
different PCF2103s on the same I
2
C-bus
must be connected to V
SS
; not user accessible
power-down pad PD selects chip power-down mode; for normal operation PD = 0
