General Description
The HT68FXX series of devices are Flash Memory I/O
www.DataSheet4Uty.cpoem8-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 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.
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.
