General Description

The series of devices are Flash Memory A/D type 8-bit high performance RISC architecture  microcontroller. Offering users the convenience of Flash Memory multi-programming features,  these devices also include a wide range of functions and features. Other memory includes an area  of RAM Data Memory as well as an area of true EEPROM memory for storage of non-volatile data  such as serial number, calibration data, etc.

Analog features include a multi-channel 12-bit A/D converter and dual comparator functions.  Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM  generation functions. Communication with the outside world is catered for by including fully  integrated SPI, UART or I2 C interface functions, two popular interfaces which provide designers  with a means of easy comminucation 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.

A full choice of HXT, LXT, 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 optimise microcontroller operation and minimise power  consumption.

The inclusion of flexible I/O programming features, Time-Base functions along with many other  features ensure that the devices 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.
