Offer- ing users the convenience of Flash Memory multi-programming features, these devices also include a wide range of functions and features, among which is their internal DC-DC Converter allowing low voltage op- eration. In addition to their Flash Program Memory there is also area of RAM Data Memory and an area of EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc. Analog features include a multi-channel 12-bit A/D con- verter and comparator functions. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. 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 oper- ation is maintained in hostile electrical environments. An extensive choice of oscillator functions is provided including a fully integrated system oscillator which re- quires 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 optimise microcontroller opera- tion and minimise power consumption. The devices also include flexible I/O programming features Time-Base functions and a range of other features. The internal PFM type step-up DC-DC Converter allows the MCU to be powered from low voltage sources, and has the advantages of high efficiency and low ripple. With a fixed and accurate 3.0V output voltage and ex- tremely low 0.7V start-up voltage, these MCU devices will be especially suitable for battery-powered applica- tions, portable handheld equipment etc. |
