DESCRIPTION
The NN325 device is an ultra-low-power multisensing
touch manager that includes optimized peripherals
dedicated for high-performance touch-sensing
applications. The device is optimized for ultra-low
power operation using five low-power modes. The
embedded powerful 16-bit RISC core based on a
MSP430™ architecture offers 16-bit registers and
constant generators to achieve maximum code
efficiency. The digitally controlled oscillator (DCO)
allows wakeup from low-power modes to active mode
in less than 1 µs. The ultra-low-power core comes
together with two built-in 16-bit timers, a universal
serial communication interface (USCI), a 10-bit ADC
with integrated reference and data transfer controller
(DTC), and 32 I/O pins.
