FT6X36
Self-Capacitive Touch
Panel Controller
INTRODUCTION
The FT6X36 Series ICs are single-chip capacitive touch panel controller IC with a built-in 16 bit enhanced Micro-controller unit
(MCU).They adopt the self-capacitance technology, which supports single point and gesture touch or two points. In conjunction with
a self-capacitive touch panel, The FT6X36 Series ICs implement the user-friendly input function and are widely used in various
portable devices, such as smart phones, MIDs ad GPS.
The FT6X36 series ICs include FT6236/FT6336/FT6436L/FT6436, the difference of their specifications will be listed individually in
this datasheet.

In this mode, the chip is set in a power down mode. It shall respond to the “RESET” or “Wakeup” signal from the host processor. The
chip therefore consumes very little current, which help prolong the standby time for the portable devices.
Host Interface Figure 2-3 shows the interface between a host processor and FT6X36. This interface consists of the following three
sets of signals:
Serial Interface
Interrupt from FT6X36 to the Host
Reset Signal from the Host to FT6X36

The serial interface of FT6X36 is I2C. The details of this interface are described in detail in Section 2.5. The interrupt signal (/INT) is
used for FT6X36 to inform the host that data are ready for the host to receive. The RSTN signal is used for the host to reset FT6X36.
After resetting, FT6X36 shall enter the Active mode.
2.4 Serial Interface
FT6X36 supports the I2C 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.
