Product details
Overview
PCF2100CT/F1,118 from NXP Semiconductors is a single-chip, silicon gate CMOS LCD driver IC designed for 40-segment, 1:2 multiplexed LCD displays. It operates from 2.25 V to 6.0 V, consumes as low as 20 µA typical supply current at 25 °C, and features an integrated oscillator and C-bus serial interface for microcontroller connectivity - used in portable instrumentation, industrial panel meters, and battery-powered display modules.
For engineers reviewing the PCF2100CT/F1,118 datasheet, PCF2100CT/F1,118 pinout, PCF2100CT/F1,118 application, or PCF2100CT/F1,118 equivalent, this page delivers verified technical context, exact SO28 package mapping, confirmed 28-pin C-bus timing behavior, and validated alternatives for LCD driver selection in space-constrained, low-power embedded systems.
Technical Context
The PCF2100CT/F1,118 implements a 22-bit C-bus serial shift register with dual backplane latches (BP1/BP2), enabling segment data loading via CLB pulse 23. Its built-in oscillator eliminates external timing components, and power-on reset ensures deterministic initialization at VPOR (1.0–1.6 V).
Bus control logic validates leading-zero detection, bit count (22 bits), and signal integrity on DLEN/DATA lines; failure halts load action and resets readiness - ensuring robust communication in noisy environments without firmware intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.25 V to 6.0 V - supports single-cell Li-ion, 3.3 V, and 5 V rails without level-shifting. |
| LCD segments | 40 segments - drives full alphanumeric 4-digit + status symbol displays. |
| Multiplex rate | 1:2 - reduces segment interconnect count and simplifies glass electrode routing. |
| Word length | 22 bits - includes 20 segment bits + 2 backplane select bits (DATA[21:20]). |
| Display frequency | 60–100 Hz - maintains flicker-free visibility across temperature (−40 °C to +85 °C). |
| Input leakage | ±1 µA max - minimizes standby current in always-on display applications. |
| Backplane impedance | 0.5–5.0 kΩ - ensures stable waveform drive into capacitive LCD loads up to 680 pF. |
Pinout & Package
PCF2100CT/F1,118 is housed in a plastic small outline package (SO28) per SOT136-1, with 28 leads and 7.5 mm body width - compatible with standard SOIC-28 footprints and reflow soldering per J-STD-020D MSL-3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLB (Pin 1) | C-bus clock burst input | Edge-triggered load pulse (pulse 23) transfers shift register contents to BP1/BP2 latches. |
| VDD (Pin 2) | Positive supply | Primary power rail; powers internal logic, oscillator, and driver stages. |
| OSC (Pin 3) | Oscillator input | Connects to internal RC oscillator; shorting to VSS enables master-slave expansion mode. |
| VSS (Pin 4) | Ground reference | Common return for logic, analog, and LCD bias paths - must be low-impedance. |
| S20–S1 (Pins 5–24) | Segment outputs | 20 dedicated segment drivers (S1–S20); S21–S32 are not bonded in PCF2100C. |
| BP2 (Pin 25) | Backplane 2 output | Drives second LCD backplane line; active when DATA[21] = LOW during CLB pulse. |
| BP1 (Pin 26) | Backplane 1 output | Drives first LCD backplane line; active when DATA[21] = HIGH during CLB pulse. |
| DATA (Pin 27) | C-bus serial data input | 22-bit word loaded MSB-first; bit 21 selects BP latch, bits 0–19 drive segments. |
| DLEN (Pin 28) | Data enable input | Active-low strobe; must be held LOW during 22-bit transfer and CLB pulse. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated oscillator | Eliminates external crystal/capacitor - reduces BOM count and PCB area by ≥3 components. |
| C-bus serial interface | 2-wire (DATA + DLEN) + CLB control - uses only 3 MCU GPIOs versus parallel 8+ bus. |
| Power-on reset (POR) | Guarantees known state at VDD ≥ VPOR (1.0–1.6 V) - prevents ghosting or undefined display. |
| Stand-alone operation | Self-contained timing and drive logic - no external controller required for basic static display. |
| Expansion capability | Master/slave chaining via OSC/VSS tie - scales to multi-driver systems without added MCU pins. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCF2111CT/1,118 | 64-segment, 34-bit word, VSO40 (40-pin) package - higher segment count but larger footprint. | Required for 6-digit+ alphanumeric or graphical segment layouts; incompatible pinout and timing (CLB pulse 35). | Select when >40 segments needed and board layout accommodates VSO40; not drop-in replaceable. |
| PCF2112CT/1,118 | 32-segment, 1:1 multiplex, VSO40 package - no BP1/BP2 latches; simpler timing (CLB pulse 35, no DATA[33] latch select). | Suitable for static or low-complexity displays where 1:1 drive simplifies glass design and eliminates backplane switching. | Choose for cost-sensitive, low-segment-count designs where 1:1 multiplexing is acceptable and SO28 footprint is not required. |
Compared with PCF2100CT/F1,118, PCF2111CT/1,118 offers greater segment density at the cost of package size and pin compatibility, while PCF2112CT/1,118 trades segment count and multiplex flexibility for simplified timing and static-drive suitability - making PCF2100CT/F1,118 the optimal balance of segment count, SO28 footprint, and 1:2 multiplex efficiency.

FAQ
What is the maximum display frequency supported by the PCF2100CT/F1,118?
The PCF2100CT/F1,118 supports a display frequency range of 60 Hz to 100 Hz under recommended operating conditions (VDD = 2.25 V to 6.0 V, Tamb = −40 °C to +80 °C). This range ensures flicker-free visibility while maintaining stable segment contrast across temperature and supply variations - critical for readability in medical and industrial displays using the PCF2100CT/F1,118.
Does the PCF2100CT/F1,118 require external components for oscillator operation?
No, the PCF2100CT/F1,118 includes a one-point built-in oscillator that requires no external crystal or capacitors. The oscillator is enabled by default when OSC is left unconnected or tied to VDD; connecting OSC to VSS configures the device for expansion mode. This integration reduces BOM cost and PCB area - a key design advantage of the PCF2100CT/F1,118.
How many LCD segments can the PCF2100CT/F1,118 drive, and what is its multiplex configuration?
The PCF2100CT/F1,118 drives exactly 40 LCD segments in a 1:2 multiplex configuration. It provides 20 dedicated segment outputs (S1–S20) and two backplane outputs (BP1, BP2) - with segment data loaded via 22-bit C-bus words where bits 0–19 map to segments and bit 21 selects the active backplane latch. This is a fixed capability of the PCF2100CT/F1,118 and cannot be altered by configuration.
What package type and lead count does the PCF2100CT/F1,118 use?
The PCF2100CT/F1,118 uses the SO28 plastic small outline package per SOT136-1 specification - featuring 28 leads, 7.5 mm body width, and standard SOIC-28 footprint compatibility. This package supports both tube and tape-and-reel (13-inch reel, part number suffix ,118) delivery formats - confirmed in NXP's official ordering information for the PCF2100CT/F1,118.
Is the PCF2100CT/F1,118 compatible with 3.3 V microcontrollers?
Yes, the PCF2100CT/F1,118 operates over a supply range of 2.25 V to 6.0 V and accepts TTL/CMOS logic levels: VIH ≥ 2.0 V and VIL ≤ 0.8 V. When powered at 3.3 V, its inputs are fully compatible with standard 3.3 V microcontrollers without level translation - a verified electrical characteristic documented in the PCF2100CT/F1,118 static characteristics table.
