General Description
The devices are Flash Memory type 8-bit high perfor-
mance RISC architecture microcontrollers. Offering us-
ers 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 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 a comparator functions. Multiple and ex-
tremely flexible Timer Modules provide timing, pulse
generation and PWM generation functions. Protective
features such as an internal Watchdog Timer, Low Volt-
age Reset and Low Voltage Detector coupled with ex-
cellent noise immunity and ESD protection ensure that
reliable operation is maintained in hostile electrical envi-
ronments.
A full choice of HXT, LXT, ERC, HIRC and LIRC oscilla-
tor functions are provided including a fully integrated
system oscillator which requires no external compo-
nents 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 mini-
mize power consumption.
The inclusion of flexible I/O programming features,
Time-Base functions along with many other features en-
sure that the devices will find excellent use in applica-
tions such as electronic metering, environmental
monitoring, handheld instruments, household appli-
ances, electronically controlled tools, motor driving in
addition to many others.
