The HT68F1x series of devices are Flash Memory I/O type 8-bit high performance RISC architecture
microcontrollers. 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 for application program data storage.
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
operation is maintained in hostile electrical environments.
A full choice of HXT, ERC, HIRC and LIRC oscillator functions are provided including a fully
integrated system oscillator which requires 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 operation and minimise power consumption.
