Product details
Overview
PCF2119RU/2/F2 from NXP Semiconductors is a low-power CMOS LCD controller and driver IC designed to drive 2×16 or 1×32 character dot-matrix displays with 5×8 dot format. It integrates on-chip LCD bias voltage generation, 18-row/80-column drivers, 80-character DDRAM, 240-character CGROM, and supports 4-bit/8-bit parallel or I²C-bus interface - enabling minimal external components in portable instrumentation displays.
For engineers reviewing the PCF2119RU/2/F2 datasheet, PCF2119RU/2/F2 pinout, PCF2119RU/2/F2 application, or PCF2119RU/2/F2 equivalent, key selection considerations include its dual-supply logic/LCD voltage architecture (VDD1: 1.5–5.5 V; VLCDOUT: 2.2–6.5 V), programmable temperature-compensated voltage multiplier (−0.16 %/K to −0.24 %/K), icon blink capability, and power-down mode consuming <2 µA.
Technical Context
The PCF2119RU/2/F2 implements a frame-inversion driving scheme with automatic bias level selection across 1:18, 1:9, and 1:2 multiplex rates. Its internal oscillator (140 kHz typical) eliminates external timing components, while configurable voltage multipliers (2×, 3×, or 4×) and independent temperature compensation ensure stable VLCD output across operating conditions.
It features dual memory architectures: 80-byte Display Data RAM (DDRAM) for display content and 240-character Character Generator ROM (CGROM) supporting alphanumeric and kana characters, plus 16-byte CGRAM for user-defined 5×8 symbols - with dedicated R17/R18 outputs for icon row control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Display Format | 2×16 or 1×32 characters, 5×8 dot matrix; supports 160 icons via dedicated R17/R18 rows |
| Logic Supply (VDD1) | 1.5 V to 5.5 V - enables operation from two alkaline cells or single Li-ion cell |
| LCD Supply (VLCDOUT) | 2.2 V to 6.5 V - generated internally with programmable temperature coefficient (−0.16 to −0.24 %/K) |
| Current Consumption | <25 µA in icon-only mode; <2 µA in power-down - critical for battery life in portable instruments |
| Interface Options | 4-bit/8-bit parallel bus (E, R/W, RS, DB0–DB7) or 2-wire I²C (SCL/SDA) - allows flexible MCU integration |
| Memory Resources | 80-byte DDRAM, 240-character CGROM, 16-byte CGRAM - sufficient for full 2-line display + custom symbols |
| Multiplex Rates | 1:18 (2-line), 1:9 (1-line + 80 icons), 1:2 (icon-only) - adapts drive strength and power to display content |
Pinout & Package
Bare die package with 168 bumps; mounted on substrate with rear-side VSS connection. Requires wire bonding or flip-chip assembly per mechanical drawing Figure 49 (NXP Rev. 12).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 (pins 1–6) | Logic supply input | Powers core logic, I/O buffers, and internal oscillator; must be 1.5–5.5 V |
| VDD2/VDD3 (pins 7–18) | High-voltage generator supply | Provides input to internal charge pump; both must be equal and 2.2–4.0 V |
| E (pin 19) | Parallel interface enable | Active-HIGH strobe; data latched on falling edge - disabled (LOW) when using I²C |
| R/W (pin 158) | Read/write control | HIGH = read DDRAM/CGROM; LOW = write; internal pull-up ensures safe default |
| VLCDSENSE (pin 36) | Voltage regulation feedback | Connects to VLCDOUT/VLCDIN for internal generation; to VLCDIN only for external supply |
| R17/R18 (pins 59, 100, 141, 142–149) | Icon row drivers | Dedicated outputs for 160-icon display mode; support blink function via Icon_ctl register |
| SCL/SDA (pins 151–152, 156–157) | I²C serial interface | Must tie to VSS1 or VDD1 when using parallel interface; SA0 (DB3) sets I²C address |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LCD bias generation | Eliminates external resistor ladder and reduces system current by >40% vs discrete bias networks |
| Programmable voltage multiplier | Configurable 2×/3×/4× stages via HV_gen register - maintains stable VLCD across VDD2/VDD3 variation |
| Icon-only drive mode (1:2 multiplex) | Reduces switching frequency and enables direct-mode VLCD = VDD2 - cuts current to <25 µA |
| Temperature-compensated VLCD | Adjusts output slope (−0.16 to −0.24 %/K) via Temp_ctl register - preserves contrast over −40°C to +85°C |
| On-chip oscillator | 140 kHz typical frequency; requires only OSC-to-VDD1 connection - no crystal or caps needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD controller and driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCF2119SU/2/F2 | Same die, identical electrical specs and pinout; differs only in marking code (PC2119-2) and sales item (12NC 935263700033) | No functional difference; used interchangeably in same PCB designs | Select when sourcing from alternate NXP distribution channel or tray packaging variant |
| ST7066U | 4-bit/8-bit parallel only; no I²C interface; lacks icon-specific row drivers (R17/R18) and icon blink function | Suitable for basic 2×16 character displays without icon overlays or low-power icon-only modes | Choose only if I²C is unnecessary and icon functionality is not required - lower cost but reduced feature set |
Compared with PCF2119SU/2/F2, the PCF2119RU/2/F2 offers identical performance and drop-in compatibility; versus ST7066U, it adds I²C support, dedicated icon drivers, and sub-25 µA icon mode - making it superior for battery-powered or icon-rich interfaces.

FAQ
What display configurations does the PCF2119RU/2/F2 support?
The PCF2119RU/2/F2 supports 2-line × 16-character or 1-line × 32-character displays using a 5×8 dot matrix format. It also drives up to 160 icons via dedicated R17 and R18 row outputs, with selectable 1:18 (full display), 1:9 (1-line + icons), or 1:2 (icon-only) multiplex rates - all managed automatically by internal configuration registers.
How does the PCF2119RU/2/F2 generate LCD bias voltage?
The PCF2119RU/2/F2 generates LCD bias voltage using an on-chip configurable voltage multiplier (2×, 3×, or 4×) powered by VDD2/VDD3, combined with internal intermediate bias level generation. VLCDOUT (2.2–6.5 V) is temperature-compensated (−0.16 to −0.24 %/K) and regulated via VLCDSENSE feedback. External VLCD supply is also supported by connecting VLCDIN/VLCDOUT appropriately.
Can the PCF2119RU/2/F2 operate with an external clock instead of the internal oscillator?
Yes, the PCF2119RU/2/F2 accepts an external clock signal applied to the OSC pin, replacing the internal oscillator. In this mode, the display frame frequency is fclk/3072. The internal oscillator is disabled when OSC is driven externally; however, the clock must remain active except during power-down mode - stopping it otherwise freezes the LCD in a damaging DC state.
What is the purpose of the PD pin on the PCF2119RU/2/F2?
The PD (Power-Down) pin on the PCF2119RU/2/F2 enables hardware-controlled ultra-low-power mode: applying HIGH to PD disables the internal oscillator, bias generation, and LCD outputs (all tied to VSS), reducing current to <2 µA while preserving DDRAM and register contents. Normal operation resumes immediately upon pulling PD LOW.
Does the PCF2119RU/2/F2 support user-defined characters?
Yes, the PCF2119RU/2/F2 includes 16-byte Character Generator RAM (CGRAM) for defining up to 16 custom 5×8 dot characters. Four CGRAM locations drive the 160 icons; eight are used if icon blink is enabled. User symbols are written via instruction set and persist across display updates - enabling brand-specific glyphs or status indicators.
