Texas Instruments MSP430F2011IPWR

Overview

MSP430F2011IPWR from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 2KB+256B flash memory, 128B RAM, and a 16-bit Timer_A with two capture/compare registers. It operates from 1.8 V to 3.6 V, draws 220 µA active current at 1 MHz/2.2 V, and supports sub-1 µs wake-up from standby mode. It is used in battery-powered sensor nodes requiring analog signal acquisition, timing control, and minimal power budget.

For engineers reviewing the MSP430F2011IPWR datasheet, MSP430F2011IPWR pinout, MSP430F2011IPWR application, or MSP430F2011IPWR equivalent, key selection criteria include its 14-pin TSSOP package, absence of ADC or USI peripherals (distinguishing it from F20x2/F20x3 variants), integrated comparator_A+, and Spy-Bi-Wire debug interface compatibility.

Technical Context

The MSP430F2011IPWR belongs to the MSP430F20x1 family and implements a 16-bit CPU with seven addressing modes, constant generators, and register-to-register execution in one cycle. Its basic clock module provides ACLK, MCLK, and SMCLK sourced from internal DCO (calibrated to ±1% at 1/8/12/16 MHz), 32-kHz crystal, or external digital clock.

It integrates a versatile analog comparator with eight-channel input multiplexer (CA0–CA7), programmable hysteresis, and output routing to P1.3/CAOUT and P1.7/CAOUT. Power management includes five software-selectable low-power modes (LPM0–LPM4), with LPM4 consuming only 0.1 µA while retaining RAM.

FAQ

What is the maximum operating frequency of the MSP430F2011IPWR?

The MSP430F2011IPWR's digitally controlled oscillator (DCO) is factory-calibrated to operate up to 16 MHz with ±1% accuracy. While the CPU supports instruction execution at this rate, actual system clock (MCLK) selection depends on application power/performance trade-offs-most designs use 1 MHz or lower to minimize active current. The MSP430F2011IPWR does not require an external crystal for basic operation but supports 32-kHz watch crystal for precise real-time clock functions.

Does the MSP430F2011IPWR include an analog-to-digital converter (ADC)?

No, the MSP430F2011IPWR does not include an ADC. It belongs to the MSP430F20x1 family, which features only the analog comparator_A+ module-not the 10-bit ADC10 (found in F20x2) or 16-bit SD16_A (found in F20x3). Its comparator supports slope A/D conversion via external RC network, but no built-in successive-approximation or sigma-delta ADC is present. This makes the MSP430F2011IPWR ideal for binary threshold detection rather than multi-level analog digitization.

What debug interface does the MSP430F2011IPWR support?

The MSP430F2011IPWR supports the Spy-Bi-Wire (SBW) interface using two pins: RST/NMI/SBWTDIO and TEST/SBWTCK. This 2-wire protocol is electrically compatible with JTAG but uses fewer pins and lower pin count. It enables full flash programming, real-time debugging, and breakpoint setting via TI's MSP-FET or compatible tools. No external level-shifting or voltage translation is needed for standard 3.3 V debug adapters.

Can the MSP430F2011IPWR drive an LCD directly?

No, the MSP430F2011IPWR does not integrate an LCD controller or charge pump driver. Unlike higher-tier MSP430 devices (e.g., MSP430F4xx or MSP430FRxx families), it lacks dedicated LCD segments, bias generation, or COM/SEG drive capability. To interface with an LCD, external components such as a dedicated LCD driver IC or discrete transistor array are required. Its GPIOs can toggle simple LED indicators but cannot sustain multiplexed LCD waveforms.

Is the MSP430F2011IPWR pin-compatible with other MSP430F20xx variants in TSSOP package?

Yes, all MSP430F20xx devices-including MSP430F2001IPWR, MSP430F2011IPWR, MSP430F2012IPWR, and MSP430F2013IPWR-in the 14-pin TSSOP (PW) package share identical pinouts and mechanical footprint. However, peripheral functionality differs: F20x1 has comparator_A+, F20x2 adds ADC10 and USI, and F20x3 adds SD16_A. Firmware and schematic must be validated for functional compatibility despite mechanical interchangeability.
