16/32-bit ARM microcontroller with external memory interface
I Up to 55 GPI, GPO, and GPIO pins. Includes 12 GPI pins, 24 GPO pins, and six GPIO
I 10-bit ADC with input multiplexing from three pins.
I Real-Time Clock (RTC) with separate power supply and power domain, clocked by a
dedicated 32 kHz oscillator. Includes a 128 byte scratch pad memory. The RTC may
remain active when the rest of the chip is not powered.
I 32-bit general purpose high-speed timer with 16-bit pre-scaler with capture and
I 32-bit millisecond timer driven from the RTC clock. Interrupts may be generated using
two match registers.
I Watchdog timer.
I Two PWM blocks with an output rate up to 50 kHz.
I Keyboard scanner function provides automatic scanning of up to an 8 × 8 key matrix.
I Standard ARM test/debug interface for compatibility with existing tools.
I Emulation trace buffer with 2 k × 24-bit RAM allows trace via JTAG.
I On-chip crystal oscillator.
I Stop mode saves power, while allowing many peripheral functions to restart CPU
I On-chip PLL allows CPU operation up to the maximum CPU rate without the need for
a high frequency crystal.
I Boundary scan for simpliﬁed board testing.
