Product details
Overview
PCF2119FU/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, character generator ROM (240 chars), display RAM (80 bytes), and supports 4-bit/8-bit parallel or I²C-bus interface - enabling minimal external components in portable telecom and POS terminals.
For engineers reviewing the PCF2119FU/2/F2 datasheet, PCF2119FU/2/F2 pinout, PCF2119FU/2/F2 application, or PCF2119FU/2/F2 equivalent, key selection factors include its 18-row/80-column output capability, programmable VLCD generator (2.2–6.5 V), icon blink function, <25 µA icon-mode current draw, and dual-supply logic (1.5–5.5 V) and LCD (2.2–6.5 V) voltage ranges.
Technical Context
The PCF2119FU/2/F2 implements a frame-inversion driving scheme with automatic bias level selection for 1:18, 1:9, or 1:2 multiplex rates. Its internal oscillator (140 kHz typical) eliminates external timing components, while configurable voltage multipliers (2×, 3×, or 4×) and temperature-compensated VLCD generation (−0.16 %/K to −0.24 %/K) ensure stable contrast across operating conditions.
It features dual supply domains: VDD1 (1.5–5.5 V) powers logic and I²C interface, while VDD2/VDD3 (2.2–4 V) feed the high-voltage generator. The chip preserves DDRAM and state during power-down mode (PD = HIGH), drawing <2 µA, and supports direct mode for reduced current when driving icons only.

Pinout & Package
Bare die package with 168 bumps; mounted on custom substrate per application. Pin assignment follows NXP's standardized PCF2119x die layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 (pins 1–6) | Logic supply input | Powers core logic, I²C interface, and data bus; accepts 1.5–5.5 V for battery compatibility |
| VDD2/VDD3 (pins 7–18) | High-voltage generator supply | Feeds internal charge pump; must be equal (VDD2 = VDD3) and within 2.2–4 V range |
| E (pin 19) | Parallel interface enable clock | Triggers read/write on falling edge; must be LOW when using I²C interface |
| R/W (pin 158) | Read/write control | HIGH = read, LOW = write; internal pull-up ensures safe default state |
| RS (pin 159) | Register select | HIGH = instruction/data register; internal pull-up simplifies microcontroller connection |
| DB0–DB7 (pins 160–167) | Bidirectional data bus | 8-bit parallel path; DB7 doubles as busy flag; DB3 serves as I²C address pin (SA0) |
| SCL/SDA (pins 151–152, 156–157) | I²C serial interface | Must be tied to VSS1 or VDD1 when using parallel interface; support standard I²C protocol |
| VLCDSENSE (pin 36) | Voltage multiplier regulation | Connects to VLCDOUT/VLCDIN for internal generation; connects to VLCDIN only for external supply |
| PD (pin 155) | Power-down control | HIGH activates ultra-low-power mode (<2 µA); retains DDRAM and state |
| POR (pin 154) | External Power-On Reset | Active-HIGH reset; must be held HIGH ≥3 oscillator periods (≥2.15 µs min) for reliable initialization |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LCD bias generation | Eliminates external resistor ladder; reduces system current and PCB area |
| Programmable multiplex rate | 1:18 (full display), 1:9 (16-char + 80 icons), or 1:2 (icon-only) - optimizes contrast and power |
| Icon blink function | Hardware-controlled blinking of up to 160 icons without CPU intervention |
| Temperature-compensated VLCD | Adjusts output voltage by −0.16 %/K to −0.24 %/K to maintain consistent contrast over temperature |
| Direct mode for icon operation | Bypasses internal charge pump; connects VLCDOUT directly to VDD2, cutting current draw |
| On-chip oscillator | 140 kHz typical frequency; requires only OSC-to-VDD1 connection - no external crystal or caps |

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 |
|---|---|---|---|
| PCF2119RU/2/F2 | Same die, identical electrical specs; differs only in marking code (PC2119-2) and sales item (12NC 935263699033) | No functional difference; used interchangeably in same bare-die mounting process | Select when sourcing from alternate NXP production lot or tray configuration |
| ST7066U | 4-bit/8-bit parallel only; no I²C interface; fixed 1:16 multiplex; no icon blink or direct mode | Limited to basic 2×16 character displays without icon-rich UIs or ultra-low-power icon-only operation | Choose only if I²C is unused and power budget allows higher active current (>100 µA) |
Compared with PCF2119FU/2/F2, PCF2119RU/2/F2 offers identical functionality with different logistics coding, while ST7066U lacks I²C, icon blink, temperature-compensated VLCD, and direct mode - making it unsuitable for battery-powered or icon-intensive designs.

FAQ
What is the primary display capability of the PCF2119FU/2/F2?
The PCF2119FU/2/F2 drives 2-line × 16-character or 1-line × 32-character LCDs in 5×8 dot format, with support for up to 160 icons using dedicated R17/R18 row outputs. It provides full DDRAM (80 bytes), CGROM (240 chars), and CGRAM (16 chars) - all integrated into a single bare-die solution optimized for minimal external components and low system current.
How does the PCF2119FU/2/F2 achieve ultra-low power consumption?
The PCF2119FU/2/F2 achieves ultra-low power via multiple design features: power-down mode draws <2 µA while preserving DDRAM; icon-only mode consumes <25 µA; on-chip bias generation eliminates external resistor current; and direct mode bypasses the charge pump to connect VLCDOUT directly to VDD2. These features make PCF2119FU/2/F2 ideal for battery-powered applications.
Does the PCF2119FU/2/F2 support both parallel and I²C interfaces simultaneously?
No - the PCF2119FU/2/F2 supports either 4-bit/8-bit parallel or 2-wire I²C interface, but not both concurrently. When using I²C, the parallel pins E, R/W, RS, and DB0–DB7 must be configured per datasheet: E must be LOW, and SCL/SDA must not float (tied to VSS1 or VDD1 if unused). This ensures signal integrity and avoids contention.
What is the role of VLCDSENSE, VLCDOUT, and VLCDIN pins on the PCF2119FU/2/F2?
These three pins configure the LCD supply architecture: VLCDOUT delivers the generated or external VLCD voltage; VLCDIN feeds the internal bias generator; VLCDSENSE regulates the charge pump. For internal generation, all three are shorted. For external supply, VLCDSENSE connects only to VLCDIN, and VLCDOUT remains open. This flexibility lets designers choose between integrated efficiency and external precision control in the PCF2119FU/2/F2.
Can the PCF2119FU/2/F2 drive custom symbols or Japanese kana characters?
Yes - the PCF2119FU/2/F2 includes 16-byte CGRAM for user-defined 5×8 symbols, and its CGROM natively supports alphanumeric, kana (Japanese), and extended character sets. The 'x' in PCF2119x denotes the specific character set variant; PCF2119FU/2/F2 implements the standard 'F' set, which includes kana glyphs. Custom symbols are written to CGRAM via instruction and addressed like standard characters in DDRAM.
