Features
Benefits
10-bit Analog-to-Digital Converter (ADC)
> Two 8-channel ADC
> 7 µs, 10-bit single conversion time, scan mode
available
> Fast, easy conversion from analog inputs like
position sensors, analog meters and
photovoltaic cells to digital values for
CPU processing
> Can effectively have 3.5 µs conversion time
by sampling same signal with both ADCs
Clock Generation Module with Phase-Lock Loop (PLL)
> Clock monitor with self clock mode in case of
no external clock
> Programmable clock frequency with 1024
options ranging from divide by 16 to multiply
by 64 from base oscillator
> Reliable, robust operation
> Provides high performance using low-cost
reference crystals
> Reduces generated noise
> Real-time interrupt
> Reduces power consumption
> Watchdog
> Easily able to implement real-time clock
Enhanced Capture Timer
> 8-channel, 16-bit with input capture, output
compare and pulse accumulator
> Flexible, programmable timer system
> 16-bit modulus down counter
8-bit or 16-bit Pulse-Wide Modulation (PWM)
> 8-channel, 8-bit or 4-channel, 16-bit PWM
> PWM supports center aligned operation
Two Serial Communications Interfaces
> 8192 prescaler option
> Efficiently implement motor control, battery
charging or digital-to-analog functions
> Asynchronous communication between the
MCU and a terminal, computer or a network
of MCUs
Three Serial Peripheral Interfaces
> Up to 6.25 Mbps
Inter IC (I²C) Bus
> 256 clock rate options
> Exact baud rate matching
> High-speed synchronous communication
between multiple MCUs or between MCU and
serial peripherals
> Provides a simple, efficient method of data
exchange between devices
Up to 91 Input/Output (I/O) Lines
> Programmable pull-ups/pull-downs
> Minimizes the need for large numbers of
connections between devices and eliminates
the need for an address decoder
> Reduce system cost
> Dual drive capability
> Able to tailor application for minimum EMC or
high current loads
