16 MHz MCU with 120KB FLASH, 4KB SRAM, AES, 12-bit ADC, comparator, DMA, UART/SPI/I2C, timer

The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consists of several devices featuring 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 calibrated digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 µs.

The MSP430F261x and MSP430F241x series are microcontroller configurations with two built-in 16-bit timers, a fast 12-bit ADC, a comparator, two 12-bit DACs, four USCI modules, DMA, and up to 64 I/O pins. The MSP430F241x devices are identical to the MSP430F261x devices, with the exception that the DAC12 and the DMA modules are not implemented.

The LQFP-64 package is also available as a nonmagnetic package for medical imaging applications.
