HT66FB30/HT66FB40/HT66FB50/HT66FB60 Rev. 1.10 2 June 4, 2010 General Description The HT66FBx0 series of devices are Flash Memory A/D type 8-bit high performance RISC architecture microcontrollers with a USB interface. Offering users the convenience of Flash Memory multi-programming features, these devices also include a wide range of functions and features. Other memory includes an area of RAM Data Memory as well as an area of EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc. Analog features include a multi-channel 12-bit A/D con- verter and dual comparator functions. Multiple and ex- tremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Communi- cation with the outside world is catered for by including fully integrated SPI or I 2 C interface functions, two popu- lar interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection en- sure that reliable operation is maintained in hostile elec- trical environments. A full choice of HXT, LXT, ERC, HIRC and LIRC oscilla- tor functions are provided including a fully integrated system oscillator which requires no external compo- nents for its implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller operation and minimize power consumption. The device contains a single USB Full-speed interface to allow data communication with an external USB host controller. It is particularly suitable for applications which require data communication between PCs and periph- eral USB hardware. An extensive choice of oscillator functions is provided including a fully integrated system oscillator which re- quires no external components for its implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller opera- tion and minimise power consumption. The devices also include flexible I/O programming features, Time-Base functions and a range of other features. |
