The HT45FM30 is a DC Fan Flash Memory A/D type 8-bit high performance RISC architecture microcontroller, especially designed for DC motor control applications. Offering users the convenience of Flash Memory multi-programming features, this device also includes a wide range of functions and features. Other memory includes an area of Data Memory as well as an area of true EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc.\n\n Analog features include a multi-channel 10-bit A/D converter, four comparator functions, internal Programmable Gain Amplifier, multi-channel PWM generator, Hall Sensor Interrupt, Capture Time Module and an 8-bit D/A converter. Multiple and extremely flexible Timer Modules provide timing and pulse generation. Communication with the outside world is catered for by including fully integrated SPI or I2C interface functions, two popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.\n\n A choice of HIRC and LIRC oscillator functions are provided including a fully integrated system oscillator which requires no external components for its implementation. 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.\n\n The inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that the device will find excellent use in applications such as electronic metering, environmental monitoring, handheld instruments, household appliances, electronically controlled tools, motor driving in addition to many others.\n\n  \n\n
