Product Details
HT66F0175/HT66F0185
With EEPROM A/D type Flash microcontroller
This series of microcontrollers is an A/D type Flash microcontroller with an 8-bit high-performance reduced instruction set. These microcontrollers have a series of functions and characteristics, and their Flash memory can be programmed multiple times, providing users with great convenience. In terms of memory, it also includes a RAM data memory and a True EEPROM memory that can be used to store non volatile data such as serial numbers and calibration data.
In terms of simulation characteristics, this series of microcontrollers includes a multi-channel 12 bit A/D converter and comparator function. It also comes with multiple flexible timer modules that can provide timing function, pulse generation function, and PWM generation function. Internal protection features such as internal WDT, low voltage reset, and low voltage detection, coupled with excellent anti-interference and ESD protection performance, ensure the reliable operation of the microcontroller in harsh electromagnetic interference environments. This series of microcontrollers provides a wide range of HXT, LXT, HIRC, and LIRC oscillator function options, and a complete system oscillator is built in without the need for peripheral components. Its ability to dynamically switch between different working modes provides users with a means to optimize microcontroller operation and reduce power consumption.
With the addition of other features such as time base function and flexible I/O usage, this series of microcontrollers can be widely used in various products, such as electronic measuring instruments, environmental monitoring, handheld measuring tools, home applications, electronic control tools, motor control, and so on.
