Product details
Overview
PCF2119RU/2DB/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 displays in 5×8 format, featuring on-chip LCD bias generation, 4-/8-bit parallel and I²C-bus interfaces, and integrated character generator ROM (240 chars) and RAM (16 user-definable symbols). It supports icon-only mode with <25 µA current draw and operates from 1.5 V to 5.5 V logic supply.
For engineers reviewing the PCF2119RU/2DB/2 datasheet, PCF2119RU/2DB/2 pinout, PCF2119RU/2DB/2 application, or PCF2119RU/2DB/2 equivalent, key selection criteria include its dual-supply architecture (VDD1/VDD2/VDD3), programmable VLCD voltage generation (2.2–6.5 V), 18-row × 80-column output capability, temperature-compensated bias, and support for both alphanumeric and Japanese kana character sets.
Technical Context
The PCF2119RU/2DB/2 implements a frame-inversion driving scheme with automatic bias level selection across 1:18, 1:9, and 1:2 multiplex rates. Its internal oscillator eliminates external timing components, while configurable voltage multipliers (2×, 3×, or 4×) generate VLCD independently of VDD1.
It integrates Display Data RAM (80 bytes), Character Generator ROM (240 × 5×8 patterns), and Character Generator RAM (16 × 5×8 slots - 4 used for 160 icons, 8 when icon blink is enabled). The chip supports direct-mode operation where VLCDOUT connects to VDD2 to reduce power in icon-only applications.

FAQ
What display configurations does the PCF2119RU/2DB/2 support?
The PCF2119RU/2DB/2 supports 2-line × 16-character or 1-line × 32-character displays in 5×8 dot format, plus icon-only operation using dedicated R17/R18 rows for up to 160 icons. It automatically configures bias voltages and timing for 1:18, 1:9, or 1:2 multiplex rates based on instruction settings - no hardware changes required to switch modes. All configurations use the same PCF2119RU/2DB/2 silicon.
How does the PCF2119RU/2DB/2 achieve ultra-low power consumption in icon mode?
The PCF2119RU/2DB/2 reduces current to <25 µA in icon mode by lowering the LCD operating voltage (via VLCD register VB), reducing output switching frequency, and enabling direct-mode operation where VLCDOUT connects internally to VDD2. This eliminates charge-pump overhead while maintaining sufficient contrast for monochrome icons - a feature confirmed in Section 8.4.1 of the PCF2119RU/2DB/2 datasheet.
Can the PCF2119RU/2DB/2 drive Japanese kana characters?
Yes, the PCF2119RU/2DB/2 includes built-in kana character patterns in its 240-character CGROM, supporting Japanese text display in 5×8 format without external font memory. The 'x' in PCF2119x denotes the character set variant, and PCF2119RU/2DB/2 implements the standard kana-enabled version documented in Table 10–15 of the PCF2119RU/2DB/2 datasheet.
What are the voltage supply requirements for the PCF2119RU/2DB/2?
The PCF2119RU/2DB/2 requires three independent supplies: VDD1 (1.5–5.5 V) for logic, and matched VDD2/VDD3 (2.2–4.0 V each) for the internal VLCD generator. VLCDOUT ranges from 2.2 V to 6.5 V and is programmable via registers VA/VB. These separate domains isolate noise and enable optimized power management - a requirement explicitly defined in Table 4 of the PCF2119RU/2DB/2 datasheet.
Is an external crystal required for the PCF2119RU/2DB/2 to operate?
No, the PCF2119RU/2DB/2 contains a fully integrated oscillator requiring no external components - simply connect OSC to VDD1. An external clock (up to 1 MHz) may be applied to OSC if precise timing or synchronization is needed, but it is optional. This on-chip oscillator is validated across temperature and voltage for all PCF2119RU/2DB/2 operating conditions per Section 8.1.2.
