C-bus data format
7.1 PCF2100C
When DATA bit 21 is HIGH, the A-latches (BP1) are loaded. With DATA bit 21 LOW, the
B-latches (BP2) are loaded. CLB pulse 23 transfers data from the shift register to the
selected latches.
7.2 PCF2111C
When DATA bit 33 is a HIGH, the A-latches (BP1) are loaded. With DATA bit 33 LOW, the
B-latches (BP2) are loaded. CLB pulse 35 transfers data from the shift register to the
selected latches.
7.3 PCF2112C
When DATA bit 33 is HIGH, the latches are loaded. CLB pulse 35 transfers data from the
shift register to the selected latches.
7.4 Bus control logic
The following tests are carried out by the bus control logic:
1. Test on leading zero
2. Test on number of DATA bits
3. Test of disturbed DLEN and DATA signals during transmission
If one of the test conditions is not fulfilled, no action follows the load condition (load pulse
with DLEN LOW) and the driver is ready to receive new data.

By connecting OSC to VSS the BP pins become inputs and generate signals synchronized to the single oscillator frequency,
thus allowing expansion of several members of the PCF21xxC family up to the BP drive capability of the master. The
PCF2112C can only function as a master for other PCF2112Cs.

8. Safety notes
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling
electrostatic sensitive devices.
Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A or
equivalent standards.
CAUTION
Static voltages across the liquid crystal display can build up when the LCD supply voltage
(VLCD) is on while the IC supply voltage (VDD) is off, or vice versa. This may cause unwanted
display artifacts. To avoid such artifacts, VLCD and VDD must be applied or removed together.

13. Handling information
All input and output pins meet the requirements of the MIL-STD-883 class 2, method 3015
ElectroStatic Discharge (ESD) test. When handling Metal-Oxide Semiconductor (MOS)
devices ensure that all normal precautions are taken as described in JESD625-A,
IEC 61340-5 or equivalent standards.
14. Packing information
14.1 Tape and reel information
For tape and reel packing information, see Ref. 10 “SOT136-1_118” and Ref. 11
“SOT158-1_118”.
15. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
15.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
15.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
• Board specifications, including the board finish, solder masks and vias
• Package footprints, including solder thieves and orientation

Lead-free soldering versus SnPb soldering
15.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities
15.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 21) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 8 and 9
