Product details
Overview
MSP430F2111TPWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB flash, 128B RAM, a 16-bit Timer_A with three capture/compare registers, and an on-chip analog comparator for slope A/D conversion - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2111TPWR datasheet, MSP430F2111TPWR pinout, MSP430F2111TPWR application, or MSP430F2111TPWR equivalent, key selection criteria include active-mode current at 1 MHz (250 µA @ 2.2 V), standby current (0.7 µA), wake-up time (<1 µs), 1.8–3.6 V supply range, and TSSOP-20 packaging compatibility with JTAG debugging and BSL serial programming.
Technical Context
The MSP430F2111TPWR implements a 16-bit RISC CPU with constant generators and seven addressing modes, executing instructions in 62.5 ns at 16 MHz. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at four frequencies (1/8/12/16 MHz), plus support for 32-kHz crystal and high-frequency external sources.
It features two 8-bit I/O ports (P1/P2) with individually configurable pullup/down resistors and edge-selectable interrupts, a Comparator_A+ with eight input channels (CA0–CA7), and a Brownout Detector. The device supports five low-power modes (LPM0–LPM4), with LPM4 drawing only 0.1 µA while retaining RAM.
