Holtek HT6800F1

Holtek HT6800F1 original Integrated Circuits IC

Description

This series of devices are a Flash MCU dedicated for use in low cost timer applications. It is a

Flash Memory type 8-bit high performance RISC architecture microcontroller. Offering users the

convenience of Flash Memory multi-programming features, the device also includes a wide range of

functions and features. Other memory includes an area of RAM Data Memory.

An extremely flexible Timer/Event Counter allows the users to count external events, measure

time intervals and pulse widths, and generate an accurate time base. Protective features such as an

internal Watchdog Timer coupled with excellent noise immunity and ESD protection ensure that

reliable operation is maintained in hostile electrical environments.

Each device of this series has a fully integrated system oscillator which requires no external

components for their implementation. The HT68F001 low speed oscillator is the internal 32kHz RC

oscillator, LIRC, while the HT68F0012 low speed oscillator is the internal 512kHz RC oscillator, IRC.

The inclusion of flexible I/O programming features, Time-Base function along with many other

features ensure that the device will find excellent use in Timer applications such as water filter

elements, toasters, on/off LEDs, Chargers, clock alarm and electricity cake clangs etc.
