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.  8051-based MCU This MCU is 8051 compatible with some enhancements. For instant, larger program and data memories are supported. In addition, a Multiplication-Division unit (MDU) is implemented to speed up the touch detection algorithms. Furthermore, a Flash ROM is im- plemented to store programs and some key parameters. Complex signal processing algorithms are implemented with firmware running on this MCU to process further the received signals in order to detect the touches reliably. Communication protocol software is also implemented on this MCU to exchange data and control information with the host processor.  External Interface I2C/SPI: an interface for data exchange with host INT: an interrupt signal to inform the host processor that touch data is ready for read    WAKE: an interrupt signal for the host to change FT5x06 from Hibernate to Active mode  /RST: an external low signal reset the chip.  A watch dog timer is implemented to ensure the robustness of the chip.  A voltage regulator to generate 1.8V for digital circuits from the input VDD3 supply  Power On Reset (POR) is active until VDDD is higher than some level and hold decades of μs. 2.1 MCU This section describes some critical features and operations supported by the 8051 compatible MCU. Figure 2-2 shows the overall structure of the MCU block. In addition to the 8051 compatible MCU core, we have added the following circuits,  MDU: A 16x8 Multiplier and A 32/32 Divider  Program Memory: 28KB Flash  Data Memory: 6KB SRAM  Real Time Clock (RTC): A 32KHz RC Oscillator  Timer: A number of timers are available to generate different clocks  Master Clock: 24/ 48MHz from a 48MHz RC Oscillator  Clock Manager: To control various clocks under different operation conditions of the system Figure 2-2 MCU Block Diagram Operation Modes 2.2 FT5x06 operates in the following three modes:  Active Mode When in this mode, FT5x06 actively scans the panel. The default scan rate is 60 frames per second. The host processor can configure FT5x06 to speed up or to slow down.  Monitor Mode THIS DOCUMENT CONTAINS INFORMATION PROPRIETARY TO FOCALTECH SYSTEMS CO., LTD., AND MAY NOT BE REPRODUCED, DISCLOSED OR USED IN WHOLE OR PART WITHOUT THE EXPRESS WRITTEN PERMISSION OF FOCALTECH SYSTEMS CO., LTD.

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 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 Host Interface TP Module TP TX RX FT5x06 Serial Interface /INT /WAKE Host 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 FT5x06 supports the I2C or SPI interfaces, which can be used by a host processor or other devices. Serial Interface I2C 2.4.1 The I2C is always configured in the Slave mode. The data transfer format is shown in Figure 2-4.

The phase relationship between the data and the clock can be defined by the two registers: phase and polck. Some data transfer examples can be found in Figure 2-7 to Figure 2-10.

When in the Master mode, the SPI needs to supply the data clock, whose frequency relationship with the Master clock can be set by CLKDVD bits of the SPI0CON register. When it is configured in the Slave mode, the clock, SCK, is supplied by the external Master.
