PCD8544中文资料飞利浦数据手册PDF规格书

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.

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.
