The MSP430F1xx series is a low-power microcontroller produced by Texas Instruments, USA. It has a low supply voltage range, ultra-low power consumption, five power-saving modes, a 16-bit RISC architecture, a 125 ns instruction cycle time, three-channel internal DMA, a 12-bit A/D converter, 16-bit timers, serial communication interfaces, a power supply voltage monitor/monitor, serial on-board programming, etc.
The MSP430x15x/16x/161x series are mixed‑signal microcontrollers that combine a 16‑bit RISC CPU with ultra‑low‑power operation, multiple timers, 12‑bit ADC/DAC, and a variety of serial interfaces. They are designed for battery‑powered sensor, industrial‑control, and handheld meter applications.
This handbook details the electrical specifications, pin‑out tables, functional block diagrams, mechanical dimensions, and available package options for the devices. It also lists terminal descriptions, power‑mode currents, and the full set of on‑chip peripherals.
