TI NN325TRHARQ1

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.
