General Description
The HT48F50E is an 8-bit high-performance, RISC ar-
chitecture microcontroller devices specifically designed
for multiple I/O control product applications. Device flex-
ibility is enhanced with their internal special features
such as power-down and wake-up functions, oscillator
options, buzzer driver, etc. These features combine to
ensure applications require a minimum of external com-
ponents and therefore reduce overall product costs.
Having the advantages of low-power consumption,
high-performance, I/O flexibility as well as low-cost,
these devices have the versatility to suit a wide range of
application possibilities such as industrial control, con-
sumer products, subsystem controllers, etc.
The device utilises a Flash type Program Memory, and
therefore have multi-programmable capabilities offering
the advantages of easy and efficient program updates.
The non-volatile internal EEPROM also offers the capa-
bility of storing information such as product part num-
bers, calibration data and other specific product
information. etc. The device is fully supported by the
Holtek range of fully functional development and pro-
gramming tools, providing a means for fast and efficient
product development cycles.
