Product Data Sheet
1. Description
Doc# : D-FT5502-1004 ( Version : 1.0 )
DDCN# : DC-1002003
FT5502 series ICs are single chip capacitive touch panel controller ICs with a built-in 8 bit Micro-controller
unit (MCU). It adopts the mutual capacitance approach, which supports true multi-touch capabilities. In
conjunction with a mutual capacitive touch panel, FT5502 facilitates user friendly input functions, which can be
used for portable devices, such as cellular phones, digital cameras, and notebook personal computers.
2. Typical Applications
FT5502 accommodates a wide range of applications from with a set of buttons up to a 2D touch sensing
device.
Touch pad
Portable MP3 and MP4 media players
Navigation systems, GPS
Digital cameras
Game consoles
Car applications
POS (Point of Sales) devices
Writing pad
DV
Mouse
LCD monitor
Smart Remote Controller
3. Features
Low cost solution
Mutual capacitive sensing techniques
True multi-touch with up to 5 points of absolution X and Y coordinates
Auto calibration: Insensitive to capacitance and environmental variations
