NXP Semiconductors PCF2113DH/4,557

Overview

PCF2113DH/4,557 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 LCDs with 5×8 dot format. It integrates on-chip LCD bias voltage generation, 18-row/60-column drivers, 80-byte DDRAM, 240-character CGROM, and supports 4-bit/8-bit parallel and I²C-bus interfaces. Used in telecom equipment, POS terminals, and portable instruments.

For engineers reviewing the PCF2113DH/4,557 datasheet, PCF2113DH/4,557 pinout, PCF2113DH/4,557 application, or PCF2113DH/4,557 equivalent, key selection criteria include its dual-voltage supply architecture (VDD1: 1.8–5.5 V, VDD2: 2.2–4.0 V), icon-mode current reduction (<25 µA), programmable temperature-compensated VLCD generator, and LQFP100 package compatibility with character/icon display systems.

Technical Context

The PCF2113DH/4,557 implements a fully integrated timing and bias architecture for segmented LCDs, featuring automatic multiplex rate selection (1:18, 1:9, or 1:2) based on display configuration. Its on-chip VLCD generator uses two 6-bit registers (VA/VB) to set nominal operating voltage from 1.90 V to 6.86 V at 27 °C, with programmable −0.16 %/K to −0.24 %/K temperature compensation.

It embeds dual supply domains: VDD1 powers logic and oscillator (with OSC pin requiring connection to VDD1), while VDD2/VDD3 power the VLCD generator. The chip supports direct mode (DM bit) to bypass internal VLCD generation and route VDD2 directly to VLCDOUT during icon-only operation, reducing current consumption for MUX 1:9 and icon displays.

FAQ

What display configurations does the PCF2113DH/4,557 support?

The PCF2113DH/4,557 supports two primary display modes: 2 lines × 12 characters (5×8 dot format) or 1 line × 24 characters. It also drives up to 120 icons using dedicated R17 and R18 rows. Multiplex rates are automatically selected - 1:18 for 2-line operation, 1:9 for 1-line, and 1:2 for icon-only mode - with corresponding bias voltages generated on-chip.

How does the PCF2113DH/4,557 achieve ultra-low power consumption in icon mode?

The PCF2113DH/4,557 achieves <25 µA in icon mode by reducing the LCD operating voltage (VLCD) and lowering the output switching frequency. This is enabled by dedicated icon rows (R17/R18), programmable VLCD registers (VA/VB), and the Direct Mode (DM) bit that routes VDD2 directly to VLCDOUT - eliminating internal voltage multiplication losses during icon-only updates.

Can the PCF2113DH/4,557 operate with a single 3.3 V supply?

Yes - the PCF2113DH/4,557 supports VDD1 = 3.3 V (within 1.8–5.5 V range) for logic and interface operation. However, VLCD generation requires VDD2 = 2.2–4.0 V; if using internal VLCD, VDD2 must be supplied separately. For single-supply systems, VDD2 can be derived from VDD1 via regulator or charge pump, but VDD2 and VDD3 must be equal per datasheet requirement.

What is the function of the DB3/SA0 pin on the PCF2113DH/4,557?

DB3/SA0 serves dual functionality: as bidirectional data bit 3 in 8-bit parallel mode, and as the I²C slave address input (SA0) in I²C mode. When using I²C, SA0 sets the LSB of the 7-bit device address (0x27 or 0x26). In 4-bit parallel mode without read operations, DB3 may be tied to VSS1 or VDD1 instead of left floating - per Table 5 note [4].

Does the PCF2113DH/4,557 require external components for oscillator operation?

No - the PCF2113DH/4,557 features an on-chip oscillator requiring no external capacitors or crystals. When enabled, the OSC pin must be connected directly to VDD1. An external clock (up to 1 MHz) may alternatively be applied to OSC, but stopping the clock is only permitted in Power-down mode; otherwise, the LCD freezes in DC state.
