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.
