Texas Instruments MSP430F5 & MSP430F6 Mixed-Signal Microcontrollers

Texas Instruments MSP430F665x, MSP430F645x, MSP430F565x, MSP430F535x Mixed-Signal Microcontrollers consists of several devices that feature different sets of peripherals targeted for various applications. The MSP430F5/6 architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications.

TI MSP430F5 and MSP430F6 Mixed-Signal Microcontrollers feature a powerful 16-bit RISC CPU, 16-bit registers, and constant generators, contributing to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3µs (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 3.3V 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.
