The device is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller. 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 RAM Data Memory as well as an area of Emulated EEPROM memory for storage of non-volatile data such as serial numbers, calibration data, etc.
Analog feature includes a multi-channel 10-bit A/D converter. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Protective features such as an internal Watchdog Timer and Low Voltage Reset function coupled with excellent noise immunity and ESD protection ensures that reliable operation is maintained in hostile electrical environments.
A full choice of internal high and low speed oscillators are provided and the two fully integrated system oscillators require no external components for their 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.
The inclusion of flexible I/O programming features and Time Base funcitons along with other features ensure that the device will find excellent use in electronic metering, environmental monitoring, handheld instruments, household appliances, electronically controlled tools, motor driving in addition to many others.
