Product data sheet
Digital peripherals:
Analog peripherals:
Serial interfaces:
Clock generation:
Power control:
Up to 54 General-Purpose I/O (GPIO) pins with configurable pull-up/pull-down
resistors, repeater mode, and open-drain mode.
Up to 8 GPIO pins can be selected as edge and level sensitive interrupt sources.
Two GPIO grouped interrupt modules enable an interrupt based on a
programmable pattern of input states of a group of GPIO pins.
High-current source output driver (20 mA) on one pin.
High-current sink driver (20 mA) on true open-drain pins.
Four general-purpose counter/timers with a total of up to 5 capture inputs and 13
match outputs.
Programmable Windowed WatchDog Timer (WWDT) with a dedicated, internal
low-power WatchDog Oscillator (WDO).
10-bit ADC with input multiplexing among eight pins.
USB 2.0 full-speed device controller.
USART (Universal Synchronous Asynchronous Receiver/Transmitter) with
fractional baud rate generation, internal FIFO, a full modem control handshake
interface, and support for RS-485/9-bit mode and synchronous mode. USART
supports an asynchronous smart card interface (ISO 7816-3).
Two SSP (Synchronous Serial Port) controllers with FIFO and multi-protocol
capabilities.
I
a data rate of up to 1 Mbit/s with multiple address recognition and monitor mode.
Crystal Oscillator with an operating range of 1 MHz to 25 MHz (system oscillator).
12 MHz high-frequency Internal RC oscillator (IRC) that can optionally be used as
a system clock.
Internal low-power, low-frequency WatchDog Oscillator (WDO) with programmable
frequency output.
PLL allows CPU operation up to the maximum CPU rate with the system oscillator
or the IRC as clock sources.
A second, dedicated PLL is provided for USB.
Clock output function with divider that can reflect the crystal oscillator, the main
clock, the IRC, or the watchdog oscillator.
Integrated PMU (Power Management Unit) to minimize power consumption during
Sleep, Deep-sleep, Power-down, and Deep power-down modes.
Power profiles residing in boot ROM provide optimized performance and minimized
power consumption for any given application through one simple function call.
Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep
power-down.
Processor wake-up from Deep-sleep and Power-down modes via reset, selectable
GPIO pins, watchdog interrupt, or USB port activity.
Processor wake-up from Deep power-down mode using one special function pin.
Power-On Reset (POR).
Brownout detect with four separate thresholds for interrupt and forced reset.
