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.

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.

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 I²C 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.

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.
