NXP Semiconductors PCF2113DU/2/F4,026

Overview

PCF2113DU/2/F4 from NXP Semiconductors is a low-power CMOS LCD controller/driver IC designed to drive 2-line × 12-character or 1-line × 24-character dot-matrix displays in 5×8 format, with integrated on-chip VLCD generation, temperature-compensated bias voltage synthesis, and dual-interface support (4/8-bit parallel or I²C). It operates from 1.8 V to 5.5 V logic supply and supports icon-only mode for <25 µA current draw - ideal for battery-powered telecom and POS terminals.

For engineers reviewing the PCF2113DU/2/F4 datasheet, PCF2113DU/2/F4 pinout, PCF2113DU/2/F4 application, or PCF2113DU/2/F4 equivalent, key selection criteria include its 18-row/60-column driver capability, programmable VLCD generator (1.90–6.86 V), 80-byte DDRAM, 240-character CGROM, and bump-bonded die-in-tray packaging for direct COF or chip-on-glass integration.

Technical Context

The PCF2113DU/2/F4 implements a fully integrated timing architecture with an internal oscillator requiring no external components (OSC pin tied to VDD1), automatic multiplex rate switching (1:18 for 2-line, 1:9 for 1-line, 1:2 for icon-only), and synchronous power-on reset. Its display control logic includes dedicated DDRAM address counter auto-increment/decrement and instruction decoding for common HD44780-compatible commands.

On-chip bias generation uses a 5-level scheme for 1:18 MUX, automatically configuring V1–V5 relative to VLCD per Table 6; VLCD itself is generated via configurable 2/3/4-stage voltage multiplier with −0.16 %/K to −0.24 %/K temperature compensation. Icon mode reduces both VLCD and output switching frequency, enabling sub-25 µA operation when only R17/R18-driven icons are active.

FAQ

What is the primary function of the PCF2113DU/2/F4 in an LCD system?

The PCF2113DU/2/F4 serves as a complete single-chip LCD controller and driver for 2×12 or 1×24 character displays. It manages display data storage (80-byte DDRAM), character generation (240-character CGROM + 16-slot CGRAM), on-chip VLCD and bias voltage synthesis, and interface logic for either 4/8-bit parallel or I²C communication - eliminating need for external bias networks or discrete drivers. Its role is to translate MCU commands into precise segment and backplane waveforms.

How does the PCF2113DU/2/F4 achieve ultra-low power consumption in icon-only mode?

The PCF2113DU/2/F4 achieves <25 µA in icon-only mode by reducing both the generated VLCD voltage and the output switching frequency. When configured for 1:2 multiplex (icon mode), it drives only R17/R18 rows and associated columns at lower frequency, while the VLCD generator is programmed to a reduced value optimized for icon contrast - all controlled via dedicated instruction set without MCU intervention. Power-down mode further drops current to <2 µA.

Can the PCF2113DU/2/F4 drive displays beyond 2×12 or 1×24 characters?

No - the PCF2113DU/2/F4 is architecturally limited to 80 DDRAM addresses and 18 row drivers (R1–R18), supporting only 2×12 (24 chars) or 1×24 (24 chars) text plus up to 120 icons driven by R17/R18. Its 60 column drivers (C1–C60) map directly to these configurations; attempting larger displays would exceed DDRAM addressing range and row/column driver capacity. For higher-resolution needs, NXP's PCF8576 or equivalent controllers are recommended.

What are the critical supply voltage requirements for the PCF2113DU/2/F4?

The PCF2113DU/2/F4 requires two independent supplies: VDD1/VSS1 (1.8–5.5 V) for logic core and interface, and VDD2/VDD3/VSS2 (2.2–4.0 V) for the VLCD generator. VDD2 must equal VDD3. VLCD output range is 1.90–6.86 V (programmable), but operation above 6.5 V risks device damage. All supplies must be decoupled locally; VLCD pins require ceramic capacitor to VSS2 when internally generated.

Is the PCF2113DU/2/F4 pin-compatible with standard HD44780-based controllers?

The PCF2113DU/2/F4 supports HD44780-compatible instruction set (e.g., clear display, cursor shift, DDRAM addressing) but is not pin-compatible due to its dual-supply architecture (VDD1/VDD2/VSS1/VSS2), integrated VLCD pins (VLCDOUT/VLCDIN/VLCDSENSE), and 112-pad bump layout. While software drivers can often be reused, hardware redesign is required to accommodate separate logic and VLCD supplies and the absence of external bias resistor connections.
