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.
