Product details
Overview
PCF2119DU/2/2 from NXP Semiconductors is a low-power CMOS LCD controller and driver IC designed to drive 2×16 or 1×32 character dot-matrix LCDs 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 instrumentation displays.
For engineers reviewing the PCF2119DU/2/2 datasheet, PCF2119DU/2/2 pinout, PCF2119DU/2/2 application, or PCF2119DU/2/2 equivalent, key selection criteria include its 18-row/80-column output capability, programmable VLCD generator (2.2–6.5 V), icon blink function, <25 µA icon-mode current, and dual-supply operation (VDD1: 1.5–5.5 V; VDD2/VDD3: 2.2–4 V).
Technical Context
The PCF2119DU/2/2 implements frame inversion driving for DC voltage compensation across LCD segments and supports three multiplex rates: 1:18 (2-line/1-line full display), 1:9 (1-line + 80 icons), and 1:2 (icon-only mode). Its internal oscillator requires no external components, and external clock input is accepted at OSC pin.
It features two independent voltage domains: VDD1/VSS1 for logic and VDD2/VDD3/VSS2 for high-voltage generation. Temperature-compensated VLCDOUT (−0.16 %/K to −0.24 %/K) is programmable via registers VA/VB, and bias levels are auto-configured per selected multiplex rate using on-chip intermediate voltage generation.

Pinout & Package
Bare die package with 168 bumps; mounted on custom substrate per application. Not a surface-mount IC - requires wire bonding or flip-chip integration into module-level assembly.
| Pin/Terminal | Circuit Role | Design Meaning |

| VDD2/VDD3 (pins 7–18) | High-voltage generator supply | Feeds internal charge pump; must be equal (VDD2 = VDD3) and 2.2–4 V |
| E (pin 19) | Parallel bus enable | Active-HIGH strobe for read/write; data latched on falling edge |
| R/W (pin 158) | Read/write control | HIGH = read DDRAM/CGROM; LOW = write; internal pull-up |
| RS (pin 159) | Register select | HIGH = data register (DDRAM/CGRAM); LOW = instruction register |
| DB0–DB7 (pins 160–167) | Bidirectional data bus | 8-bit parallel interface; DB7 doubles as busy flag; internal pull-ups on all lines |
| SCL/SDA (pins 151–152, 156–157) | I²C serial interface | Must be tied to VSS1 or VDD1 when using parallel interface; SA0 = DB3 alternate function |

| PD (pin 155) | Power-down control | HIGH enters ultra-low-power state (<2 µA); preserves RAM and state |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Telecom Equipment Display | Portable Instrument UI |
|---|---|
Use Scenario: Front-panel alphanumeric display on digital multimeters or handheld spectrum analyzers. IC Role / Device Role / Timing Role: LCD controller managing 2×16 character rendering, icon status indicators, and cursor positioning via DDRAM addressing. Use Value: Ultra-low icon-mode current (<25 µA) extends battery life; direct mode further reduces power when only icons are active. | Use Scenario: Status and measurement readout on battery-powered gas detectors or environmental sensors. IC Role / Device Role / Timing Role: Standalone display driver interfacing to low-power MCU via I²C, handling kana/Japanese glyphs and user-defined symbols. Use Value: Integrated CGROM (240 chars) and CGRAM (16×5×8) eliminate external font storage; 1.5 V logic support enables direct connection to Li-ion/Li-SOCl₂ systems. |

Use Scenario: Customer-facing display on compact POS terminals showing transaction totals and product names. IC Role / Device Role / Timing Role: Parallel-interface LCD driver supporting 1×32 character layout with automatic address wrap-around and display shift. Use Value: 80-byte DDRAM accommodates full line buffering; 1:18 multiplex ensures high contrast on standard STN modules without external bias tuning. | Use Scenario: Operator interface on DIN-rail mounted PLC accessories or HVAC controllers. IC Role / Device Role / Timing Role: Robust display controller with external POR (pin 154) and power-down (pin 155) for brown-out resilience and energy-aware sleep modes.

FAQ
What is the primary function of the PCF2119DU/2/2 in an LCD system?
The PCF2119DU/2/2 serves as a complete LCD controller and driver IC that manages display data storage (80-byte DDRAM), character generation (240-character CGROM + 16-user CGRAM), bias voltage synthesis (VLCDOUT), and segment/column timing for 2×16 or 1×32 character LCDs. It eliminates need for external bias resistors or clock sources, reducing system-level component count and power consumption in the PCF2119DU/2/2-based design.
Does the PCF2119DU/2/2 support Japanese kana characters?
Yes, the PCF2119DU/2/2 includes built-in kana character patterns in its 240-character CGROM, formatted in 5×8 dot matrix. These glyphs are accessible via standard ASCII-compatible code mapping and require no external font tables - enabling native Japanese text rendering in devices using the PCF2119DU/2/2 without MCU-side glyph processing.
How does the PCF2119DU/2/2 achieve ultra-low power in icon-only mode?
The PCF2119DU/2/2 achieves <25 µA current in icon-only mode by switching to 1:2 multiplex drive, reducing LCD output switching frequency, and enabling direct mode - where VLCDOUT is internally connected to VDD2 instead of the charge pump. This bypasses high-current voltage multiplication while maintaining sufficient contrast for static icon display, a key efficiency feature of the PCF2119DU/2/2.
Can the PCF2119DU/2/2 operate with a single 3.3 V supply?
Yes - the PCF2119DU/2/2 supports VDD1 = 3.3 V for logic and can generate VLCDOUT internally using VDD2/VDD3 = 3.3 V (within 2.2–4 V range). However, VLCDOUT will be limited to ~4.8 V (per VA=32 in Table 6), which is sufficient for most 3.3 V-driven STN LCDs; for higher-VLCD requirements, separate 3.6 V supplies on VDD2/VDD3 are recommended in the PCF2119DU/2/2 implementation.
What is the role of the VLCDSENSE pin on the PCF2119DU/2/2?
The VLCDSENSE pin provides feedback to the internal VLCD regulator, enabling closed-loop control of the generated LCD supply voltage. When VLCD is generated internally, VLCDSENSE must be connected to both VLCDOUT and VLCDIN; when using an external VLCD source, it connects only to VLCDIN. This pin ensures stable, temperature-compensated biasing - a critical function for consistent contrast across operating conditions in the PCF2119DU/2/2.
