20 MHz MCU with 512KB Flash, 66KB SRAM, 12-bit ADC, 12-bit DAC, comparator, DMA, 160 seg LCD

The TI MSP family of ultra-low-power microcontrollers consists of several devices that feature different sets of peripherals targeted for various applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3 µs (typical).

The MSP430F665x and MSP430F565x series are microcontroller configurations with four 16-bit timers, a high-performance 12-bit ADC, three USCIs, a hardware multiplier, DMA, an RTC module with alarm capabilities, a comparator, USB 2.0, and up to 74 I/O pins.

The MSP430F645x and MSP430F535x series are microcontroller configurations with an integrated 3.3-V LDO, four 16-bit timers, a high-performance 12-bit ADC, three USCIs, a hardware multiplier, DMA, an RTC module with alarm capabilities, a comparator, and up to 74 I/O pins.
