The HT69Fx0A series of devices are Flash Memory LCD type 8-bit high performance RISC architecture microcontrollers, designed for applications which require an LCD 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.
Analog features include 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 internal and external oscillator functions are provided including fully integrated low and high speed system oscillators which requires no external components for their 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 consumer products, handheld instruments, household appliances, electronically controlled tools and motor driving in addition to many others.
