General Description

The HT68FXX 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 as well as

an area of EEPROM memory for storage of non-volatile

data such as serial numbers, calibration data etc.

Multiple and extremely flexible Timer Modules provide

timing, pulse generation and PWM generation func-

tions. Analog features include dual comparator func-

tions. Communication with the outside world is catered

for by including fully integrated SPI or I

2C interface func-

tions, two popular interfaces which provide designers

with a means of easy communication with external pe-

ripheral hardware. Protective features such as an inter-

nal 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, 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-

mise 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.
