FT5506/FT5606/FT5616/FT5816
True Multi-Touch
Capacitive Touch Panel Controller
INTRODUCTION
FT5506, FT5606, FT5616 and FT5816 are the single-chip capacitive touch panel controller with a built-in Micro-Controller Unit
(MCU) for supporting especially large-sized mutual capacitive touch panel. They all adopt the mutual capacitance technology,
which can realize true multi-touch performance. Being coupled with a mutual capacitive touch panel,
FT5506/FT5606/FT5616/FT5816 can implement the user-friendly inputting function and be widely used in various portable devices
in large size, such as MIDs, PADs, notebooks, tablet computer, etc.

2 FUNCTIONAL DESCRIPTION
2.1 Architectural Overview
Figure2-1 shows the overall architecture for the FT5506/FT5606/FT5616/FT5816, But FT5506/FT5606 is without USB.
Figure 2-1 FT5506/FT5606/FT5616/FT5816 System Architecture Diagram
The FT5506/FT5606/FT5616/FT5816 is comprised of five main functional parts which are listed as below,
Touch Panel Interface Circuits
The main function for the AFE and AFE controller is to interface with the touch panel. It scans the panel by sending AC signals to the
panel and processes the received signals from the panel. So, it supports both Transmit (TX) and Receive (RX) functions. Key pa-
rameters to configure this circuit can be sent via serial interfaces, which will be explained in detail in a later section.
Enhanced MCU
For the Enhanced MCU, larger program and data memories are supported. Furthermore, a Flash ROM is implemented to store
