Description
The HT66F0185 is an A/D type 8-bit MCU with Holtek’s high-performance RISC architecture core. Its flexible Timer Modules provide timing, pulse generation, and PWM generation functions. The internal LED/LCD drivers support 4 segments with current output control which are able to drive LED/LCD displays directly without requiring additional external current-limiting resistors or transistors. A full choice of HXT, LXT, HIRC, and LIRC oscillator functions are provided. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimize microcontroller operation and minimize power consumption.
