FEATURES
GENERAL DESCRIPTION
• Driving standard 31⁄2 or a 4-digit LCD
• Internal voltage regulator for 5 V LCD
• Option for external stabilized voltage supply
• 4.19 MHz oscillator
The PCF1171C is a single chip, 4.19 MHz CMOS car clock
circuit indicating hours and minutes. It is designed to drive
a 31⁄2 or 4-digit liquid crystal display (LCD).
Two external single-pole, single-throw switches will
accomplish all time setting functions. A bonding option
allows the selection of 12-hour or 24-hour display mode.
The circuit is battery-operated via an internal 5 V voltage

OPERATIONAL INPUTS
Set minutes/reset seconds, switch S2
Operational inputs S1, S2 and S3 have an internal pull-up
resistor to facilitate use of external single-pole,
single-throw switches. A specific debounce circuit is
integrated as protection against contact debounce and
parasitic voltages.
When S2 is closed, the minute setting is corrected
according to the correction mode determined by S6 (see
Chapter “Input options”).
The seconds counter is reset to zero each time S2 is
closed, and begins running each time S2 is opened.
In the description below, an arrangement as shown in
Fig.5 is assumed and S1, S2 and S3 refer to the external
switches rather than the corresponding inputs.
Segment test/reset, switches S1 and S2
If S1 and S2 are closed simultaneously all LCD segments
are switched on. When the switches are released, the
clock starts at 1 : 00 in the 12-hour mode or 0 : 00 in the
24-hour mode.
Set hours, switch S1
Closure of S1 increments the hours according to the
correction mode selected by S6 (see Chapter
“Input options”).

Time correction ±2 minutes, switch S3
12/24-hour mode, switch S5
For 12-hour display mode, S5 is connected to VDD
This switch operates in two ranges:
.
For 24-hour display mode, S5 is connected to VSS
.
• Displayed time ≥ 58 minutes 00 seconds
• Displayed time ≤ 1 minute 59 seconds.
Single/continuous correction mode, switch S6
When switch S3 is pressed in these ranges, the minutes
and seconds are reset to zero. For displayed
time ≥ 58 minutes 00 seconds, the hour is also
incremented by one.
For single-set correction mode, S6 is connected to VDD
Each closure of S1 or S2 advances the counter by one.
.
For continuous-set correction mode, S6 is connected to
VSS. Momentary closure of S1 or S2 causes single
increments as for single-set correction mode. If S1 or S2 is
kept closed for more than 1s, the counter is automatically
incremented by 1 for each full second that S1 or S2 is kept
closed.
INPUT OPTIONS
In the description below S4, S5 and S6 refer to the external
switches shown in Fig.5 rather than to the corresponding
inputs.
TESTING
In a real application, these inputs will normally be bonded
to the appropriate level to give the required function mode.
In normal operation the test inputs TR (pin 38) and TS
(pin 39) have to be connected to VDD (pin 23). A test
frequency (64 Hz) is available at BP (pin 5). The test mode
is activated by connecting TS to VSS (pin 20). All output
frequencies are then increased by a factor of 65536.
In this mode the maximum input frequency is 100 kHz
(external generator at OSC IN). By connecting TR to VSS
all counters (seconds, minutes and hours) are stopped.
After connecting TR to VDD all counters start from an initial
state.
Internal/external regulation, switch S4
For internal regulation, S4 is closed, the internal voltage
regulator is active and the voltage supply for the LCD is
regulated to 5 V. For external regulation, S4 is open and
the circuit has to be supplied with an externally regulated
voltage.
The switches/inputs described above also operate in the
test mode.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).

HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
advisable to take handling precautions appropriate to handling MOS devices. Advice can be found in
“Data Handbook IC16, General, Handling MOS Devices”.

SOLDERING
Introduction
Wave soldering
Wave soldering techniques can be used for all VSO
packages if the following conditions are observed:
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
• The package footprint must incorporate solder thieves at
the downstream end.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Reflow soldering
Reflow soldering techniques are suitable for all VSO
packages.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
6 seconds. Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Repairing soldered joints
Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

General description
The PCF1171C is a single chip, 4.19 MHz CMOS car clock circuit indicating hours and minutes. It is
designed to drive a 3 1/2 or 4-digit liquid crystal display (LCD).
Catalog by
System
•
Two external single-pole, single-throw switches will accomplish all time setting functions. A bonding option
allows the selection of 12-hour or 24-hour display mode. The circuit is battery-operated via an internal 5 V
voltage regulator or by an external stabilized voltage supply.
