• Manufacturer Part Number: pcf8548
• Description: 65 X 102 Pixels Matrix Lcd Driver
• Manufacturer: NXP Semiconductors

Philips Semiconductors
The pinning of the PCF8548 is optimized for single plane wiring e.g. for chip-on-glass display modules, or for TCP.
Display size: 65
are: C
To reduce the sensitivity of the reset to ESD/EMC disturbances for a COG application, it is strongly recommended to
implement on the glass (ITO) a series input resistance in the reset line (The recommended minimum value is 8 k ).
