Product details
Overview
PCF2116CU/2/F1,026 from NXP Semiconductors (formerly Philips) is a single-chip CMOS LCD controller/driver designed for alphanumeric dot-matrix displays with 1–4 lines and up to 24 characters per line. It integrates on-chip LCD supply voltage (VLCD) and bias voltage generation, supports both 4-/8-bit parallel and I²C-bus interfaces, and provides 32 row and 60 column driver outputs for direct COG display connection.
For engineers reviewing the PCF2116CU/2/F1,026 datasheet, PCF2116CU/2/F1,026 pinout, PCF2116CU/2/F1,026 application, or PCF2116CU/2/F1,026 equivalent, this device is selected for low-power embedded displays requiring integrated bias generation, dual interface flexibility, and character-based UI in space-constrained telecom and portable instrument designs.
Technical Context
The PCF2116CU/2/F1,026 implements a fully integrated timing generator with internal oscillator (no external components required) and supports programmable MUX rates of 1:16 and 1:32 via Function Set instruction bits M/N. Its dual VLCD architecture allows either on-chip negative voltage generation (VOP = 1.8VDD − V0) or external supply, with automatic bias level selection based on display line count.
It contains 80-character DDRAM, 240-character CGROM (character set C), and 16-character CGRAM for user-defined symbols. The Busy Flag (DB7) and Address Counter enable reliable host synchronization, while the I²C address is fixed at 0x3A (011101 + SA0 = 0).

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD controller/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCF2116AU/2/F1,026 | Same LQFP128 package and pinout; differs only in CGROM character set (A vs C) | Supports Latin-1 extended ASCII (e.g., accented European characters) instead of set C's Greek/math symbols | Select when application requires Euro currency symbol (€), German umlauts, or French accents not present in set C |
| PCF2116GU/2/F1,026 | Identical electrical specs and package; CGROM contains Japanese katakana/hiragana glyphs (set G) | Enables native Japanese text rendering; lacks Greek/math symbols present in set C | Choose for consumer electronics targeting Japanese markets where kana input and display are mandatory |
Compared with PCF2116CU/2/F1,026, the A and G variants retain identical timing, voltage, and interface behavior but differ solely in ROM glyph content - making them drop-in replacements for display language localization without hardware or firmware changes.

FAQ
What display configurations does the PCF2116CU/2/F1,026 support?
The PCF2116CU/2/F1,026 supports 1-line (24 chars), 2-line (12×2 chars), or 4-line (12×4 chars) alphanumeric displays using 5×8 dot format. It drives these via 32 row and 60 column outputs with selectable 1:16 or 1:32 multiplexing, and maps DDRAM addresses accordingly (e.g., 00–27H + 40–67H for 2-line mode). PCF2116CU/2/F1,026 natively supports split-screen layouts common in COG displays.
How does the VLCD generation work on the PCF2116CU/2/F1,026?
The PCF2116CU/2/F1,026 generates VLCD internally using the V0 control input and Function Set bit G. When G = 1, VOP = 1.8VDD − V0; when G = 0, VLCD = V0 and VOP = VDD − V0. V0 is high-impedance (draws no current), and VLCD pins (VLCD1–3) must be decoupled to VDD. PCF2116CU/2/F1,026 supports external VLCD supply by tying V0 to VDD and applying negative voltage to VLCD pins.
Can the PCF2116CU/2/F1,026 operate with both parallel and I²C interfaces simultaneously?
No - the PCF2116CU/2/F1,026 operates in either parallel or I²C mode, selected at power-up. For I²C operation, E must be tied low, DB0–DB7 left open, and RS/R/W unused; for parallel mode, SCL/SDA/SA0 must be left unconnected. PCF2116CU/2/F1,026 does not support dynamic interface switching - mode is determined by external pin states at initialization.
What is the I²C address of the PCF2116CU/2/F1,026 and how is it configured?
The PCF2116CU/2/F1,026 has a fixed 7-bit I²C address of 0x3A (0111010 binary) when SA0 = 0, and 0x3B (0111011) when SA0 = 1. This allows two devices on the same bus. The address is hardwired - no software register configuration is required. PCF2116CU/2/F1,026 complies with standard I²C-bus protocol including START/STOP, ACK, and clock stretching.
Does the PCF2116CU/2/F1,026 include a built-in oscillator, and can it accept an external clock?
Yes - the PCF2116CU/2/F1,026 includes an on-chip oscillator requiring only OSC tied to VDD (no external components). It also accepts an external clock signal at the OSC pin; frame frequency is then fframe = fosc / 2304. External clocking enables precise timing control for applications requiring strict frame-rate stability. PCF2116CU/2/F1,026 guarantees proper LCD bias sequencing regardless of clock source.
