General Description
The series of devices are LCD type Flash Memory 8-bit high performance RISC architecture
microcontroller which is designed for a wide range of applications. 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 numbers, 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 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. 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.
