FT5x06
True Multi-Touch
Capacitive Touch Panel Controller
INTRODUCTION
The FT5x06 Series ICs are single-chip capacitive touch panel controller ICs with a built-in 8 bit Micro-controller unit (MCU).They
adopt the mutual capacitance approach, which supports true multi-touch capability. In conjunction with a mutual capacitive touch
panel, the FT5x06 have user-friendly input functions, which can be applied on many portable devices, such as cellular phones, MIDs,
netbook and notebook personal computers.
The FT5x06 series ICs include FT5206/FT5306/FT5406, the difference of their specifications will be listed individually in this
datasheet.

When in this mode, FT5x06 scans the panel at a reduced speed. The default scan rate is 25 frames per second and the host processor
can increase or decrease this rate. When in this mode, most algorithms are stopped. A simpler algorithm is being executed to determine
if there is a touch or not. When a touch is detected, FT5x06 shall enter the Active mode immediately to acquire the touch information
quickly. During this mode, the serial port is closed and no data shall be transferred with the host processor.
Hibernate Mode
In this mode, the chip is set in a power down mode. It shall only respond to the “WAKE” or “RESET” signal from the host processor.
The chip therefore consumes very little current, which help prolong the standby time for the portable devices.
2.3 Host Interface
Figure 2-3 shows the interface between a host processor and FT5x06. This interface consists of the following three sets of signals:
Serial Interface
Interrupt from FT5x06 to the Host
Wake-up Signal from the Host to FT5x06

Figure 2-3 Host Interface Diagram
The serial interfaces of FT5x06 is I2C or SPI. The details of this interface are described in detail in Section 2.5. The interrupt signal
(/INT) is used for FT5x06 to inform the host that data are ready for the host to receive. The /WAKE signal is used for the host to wake
up FT5x06 from the Hibernate mode. After exiting the Hibernate mode, FT5x06 shall enter the Active mode.
2.4 Serial Interface
FT5x06 supports the I2C or SPI interfaces, which can be used by a host processor or other devices.
2.4.1 I2C
The I2C is always configured in the Slave mode. The data transfer format is shown in Figure 2-4.
