1 / 142 page  HT66F03C/ HT66F04C/HT68F03C/ HT68F04C 8-Pin Enhanced Flash Type 8-Bit MCU with EEPROM Rev. 0.00 1 February 26, 2010 Preliminary General Description The devices are Flash Memory type 8-bit high perfor- mance RISC architecture microcontrollers. Offering users the convenience of Flash Memory multi-programming fea- tures, 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, cali- bration data etc. Analog features include a multi-channel 12-bit A/D con- verter and comparator functions. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable oper- ation is maintained in hostile electrical 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 mini- mize power consumption. The inclusion of flexible I/O programming features, Time-Base functions along with many other features en- sure that the devices will find excellent use in applica- tions such as electronic metering, environmental monitoring, handheld instruments, household appli- ances, electronically controlled tools, motor driving in addition to many others.
