Features
Integrated Analog Peripherals
? 4-ch., 10-bit ADC with automatic
compare function
? ADC channel connected to on-chip
temperature sensor
? Automatic compare function, software
programmable for greater-than, equal-to
or less-than conditions
? Asynchronous clock source
? Temperature sensor
? Internal bandgap reference channel
? Hardware triggerable using the real-time
interrupt counter
? Low-power and high-speed options
? Can be used for single slope APC and
resistance-capacitance time
? Easy interface to analog inputs/sensors
? Used to set conversion complete and
generate interrupt only when result
matches condition
Flexible Clock Options
? Internal clock source module containing
a frequency-locked loop controlled by
internal reference
Two Timer Modules
? Programmable 16-bit timer/PWM (TPM)
module
? 2-ch. TPM; each channel can be used for
input capture, output compare, buffered
edge-aligned pulse width modulation (PWM)
or buffered center-aligned PWM
? 1 x 1-ch., 16-bit timer
? 1 x 2-ch., 16-bit timer
Benefits
? Can be used to run ADC when MCU clocks
are off, such as in STOP3 low-power mode
? Calculates temperature without any external
components and saves an ADC input channel
for other use
? Constant voltage source for calibrating ADC
results requires no external components
? Takes periodic measurements without CPU
involvement; can be used in STOP3 with
compare function to take measurement and
wake MCU from STOP3 only when compare
level is reached
? Flexible configuration to meet high
performance and low power requirements
? Can eliminate cost of external clock
components, use little board space and help
to increase system reliability
? One of the most cost-effective and flexible
timer modules; each channel is independently
programmable for input capture, output
compare or buffered edge-aligned PWM or
buffered center-aligned PWM
? Timer overflow interrupt can be enabled to
generate periodic interrupts for time-based
software loops
? Two separate time bases provide different
interrupt options

System Protection
? Watchdog computer operating properly reset
with option to run from dedicated 1 kHz
internal clock source or bus clock
? Low-voltage detection with reset or interrupt
? Illegal opcode detection with reset
? Flexible flash block protection
? Security feature for flash and RAM
? Always-on power-on reset circuitry
? Resets device in instance of runaway or
corrupted code, and independent clock
source provides additional protection in case
of loss of clock
? Allows system to write/save important
variables before voltage drops too low
? Can hold device in reset until reliable voltage
levels are reapplied to the part
? Helps to secure code sections so that they
cannot be accidently corrupted by runaway
code
