The document introduces the features of the TI MSP430 series ultra-low-power microcontrollers, including supply voltage range, power consumption, clock module configuration, timer A, comparator, programming method, etc.
The MSP430x21x1 series is an ultralow-power mixed signal microcontroller with a built-in 16-bit timer, versatile analog comparator, and sixteen I/O pins. The device features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that attribute to maximum code efficiency.
The active mode current consumption is 200 µA at 1 MHz and 2.2 V.
The standby mode current consumption is 0.7 µA.
The off mode current consumption with RAM retention is 0.1 µA.
It takes less than 1 µs to wake up from standby mode.
