PCD8544

FEATURES

• Single chip LCD controller/driver

• 48 row, 84 column outputs

• Display data RAM 48 × 84 bits

• On-chip:

– Generation of LCD supply voltage (external supply

also possible)

– Generation of intermediate LCD bias voltages

– Oscillator requires no external components (external

clock also possible).

• External RES (reset) input pin

• Serial interface maximum 4.0 Mbits/s

• CMOS compatible inputs

• Mux rate: 48

• Logic supply voltage range VDD to VSS: 2.7 to 3.3 V

• Display supply voltage range VLCD to VSS

– 6.0 to 8.5 V with LCD voltage internally generated

(voltage generator enabled)

– 6.0 to 9.0 V with LCD voltage externally supplied

(voltage generator switched-off).

• Low power consumption, suitable for battery operated

systems

• Temperature compensation of VLCD

• Temperature range: −25 to +70 °C.

GENERAL DESCRIPTION

The PCD8544 is a low power CMOS LCD controller/driver,

designed to drive a graphic display of 48 rows and

84 columns. All necessary functions for the display are

provided in a single chip, including on-chip generation of

LCD supply and bias voltages, resulting in a minimum of

external components and low power consumption.

The PCD8544 interfaces to microcontrollers through a

serial bus interface.

The PCD8544 is manufactured in n-well CMOS

technology.

APPLICATIONS

• Telecommunications equipment.
