GeneralDescription

The HT66F1x series of devices are Flash Memory A/D 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.

Analog feature includes a multi-channel 12-bit A/D converter. 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.

The inclusion of flexible I/O programming features, Time-Base functions along with many other

features ensure that the devices will find excellent use in applications such as electronic metering,

environmental monitoring, handheld instruments, household appliances, electronically controlled

tools, motor driving in addition to many others.
