Detailed Description

The HT68F2420 device is a Flash Memory type 8-bit high performance RISC architecture microcontroller designed for low cost applications.

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 Data Memory which is fully accessible by the user. 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.

The device includes a 9-bit timer for IR carrier output, a Time-base function which can generate fixed time interrupt. An internal high precision 4MHz oscillator and an internal 32kHz oscillator which require no external components for their implementation are provided for the system clock and other functions. The inclusion of flexible I/O programming features, high driving current capacity with many other features ensure that the device will find excellent use in IR remote controller and timer applications which require a high precision clock, a timing function or a high driving current.
