MSP430F5131 (ACTIVE) 25MHz MCU with Two 16-bit High Res Timers, 8KB flash, 1KB RAM, 16-channel Comparator

 

Description

The TI MSP 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 digitally controlled oscillator (DCO) allows the devices to wake up from low-power modes to active mode in less than 5 µs.

The MSP430F51x2 microcontrollers include two 16-bit high-resolution timers, two USCIs (USCI_A0 and USCI_B0), a 32-bit hardware multiplier, a high-performance 10-bit ADC, an on-chip comparator, a 3-channel DMA, 5-V tolerant I/Os, and up to 29 I/O pins.

The MSP430F51x1 microcontrollers include two 16-bit high-resolution timers, two USCIs (USCI_A0 and USCI_B0), a 32-bit hardware multiplier, an on-chip comparator, a 3-channel DMA, 5-V tolerant I/Os, and up to 29 I/O pins.

Typical applications for these devices include analog and digital sensor systems, LED lighting, digital power supplies, motor controls, remote controls, thermostats, digital timers, and hand-held meters.
