FEATURES
GENERAL DESCRIPTION
• Internal voltage regulator is electrically programmable
for various LCD voltages
The PCF1178C is a single chip, 4.19 MHz CMOS car clock
circuit providing hours, minutes and seconds functions.
It is designed to drive a 4-digit duplex liquid crystal display
(LCD).
• Time calibration is electrically programmable
(no trimming capacitor required)
• LCD voltage adjusts with temperature for good contrast
Two external single-pole, single-throw switches will
accomplish all time setting functions. Time calibration and
voltage regulator are electrically programmable via an
on-chip EEPROM. The circuit is battery-operated via an
internal voltage regulator and an external resistor.
• 4.19 MHz oscillator
• 12-hour or 24-hour mode
• Operating ambient temperature: −40 to +85 °C
• 28-lead plastic SMD (SO28)
• 1 Hz set mode.

LCD voltage (see Fig.5)
The adjustable voltage regulator controls the supply
voltage (see Section “LCD voltage programming”) in
relation to temperature for good contrast, for example
when VDD = 4.5 V at +25 °C, then:
VDD = 3 to 4 V at +85 °C.
VDD = 5 to 6 V at −40 °C.

12/24-hour mode
Segment test/reset
Operation in 12-hour or 24-hour mode is selected by
connecting MODE to VDD or VSS respectively. If MODE is
left open-circuit and a reset occurs, the mode will change
from 12-hour to 24-hour mode or vice versa.
When S1 and S2 are connected to VSS, all LCD segments
are switched ON. Releasing switches S1 and S2 resets the
display. No reset occurs when DATA is connected to VSS
(overlapping S1 and S2).
Power-on
Test mode
After connecting the supply, the start-up mode is:
When TS is connected to VDD, the device is in normal
operating mode. When connecting TS to VSS all counters
(seconds, minutes and hours) are stopped, allowing quick
testing of the display via S1 and S2 (debounce and
auto-increment times are 64 times faster). TS has a
pull-up resistor but for reasons of safety it should be
connected to VDD.
MODE connected to VDD: 12-hour mode, 1:00 AM.
MODE connected to VSS: 24-hour mode, 0:00.
MODE left open-circuit: 24-hour mode, 0:00 or 1:00.
Colon
EEPROM
If FLASH is connected to VDD the colon pulses at 0.5 Hz.
If FLASH is connected to VSS the colon is static.
VPP has a pull-up resistor but for reasons of safety it should
be connected to VDD.
Time setting
Switch inputs S1 and S2 have a pull-up resistor to facilitate
the use of single-pole, single-throw contacts. A debounce
circuit is incorporated to protect against contact bounce
and parasitic voltages.
LCD voltage programming
To enable LCD voltage programming, SEL is set to
open-circuit and a level of VDD − 5 V is applied to VPP (see
Fig.6). The first pulse (tE) applied to the DATA input clears
the EEPROM to give the lowest voltage output. Further
pulses (tL) will increment the output voltage by steps of
typically 150 mV (Tamb = 25 °C). For programming,
measure VDD − VSS and apply a store pulse (tW) when the
required value is reached. If the maximum number of steps
(n = 31) is reached and an additional pulse is applied the
voltage will return to the lowest value.
Set enable
Inputs S1 and S2 are enabled by connecting ENABLE to
VDD or disabled by connecting to VSS.
Set hours
When S1 is connected to VSS the hours displayed
advances by one and after one second continues with one
advance per second until S1 is released (auto-increment).
Time calibration
To compensate for the tolerance in the quartz crystal
frequency which has been positively offset (nominal
deviation +60 × 10−6) by capacitors at the oscillator input
and output, a number (n) of 262144 Hz pulses are
inhibited every second of operation.
Set minutes
When S2 is connected to VSS the time displayed in
minutes advances by one and after one second continues
with two advances per second until S2 is released
(auto-increment). In addition to minute correction, the
seconds counter is reset to zero.

The number (n) is stored in a non-volatile memory which is achieved by the following steps (see Fig.6):
1. Set SEL to VSS and a level of VDD − 5 V to VPP
2. The quartz-frequency deviation ∆f/f is measured and (n) is calculated (see Table 1)
3. A first pulse tE is applied to the DATA input clears the EEPROM to give the highest backplane frequency
4. The calculated pulses (n) are entered in (tH, tL). If the maximum backplane period is reached and an additional pulse
is applied the period will return to the lowest value.
5. The backplane period is controlled and when correct fixed by applying the store pulse tW
6. Release SEL and VPP.

SOLDERING
Wave soldering
Introduction
Wave soldering techniques can be used for all SO
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 SO
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
6 seconds. Typical dwell time is 4 seconds at 250 °C.
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.
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 diagonallyopposite 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.
