Product details
Overview
MSP430F2001IPWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 1KB Flash + 256B information memory, 128B RAM, and a 16-bit Timer_A with two capture/compare registers. It integrates an analog comparator (Comparator_A+), brownout protection, and Spy-Bi-Wire on-chip emulation. Designed for battery-powered sensor nodes and portable measurement systems, it operates from 1.8 V to 3.6 V and supports five power-saving modes.
For engineers reviewing the MSP430F2001IPWR datasheet, MSP430F2001IPWR pinout, MSP430F2001IPWR application, or MSP430F2001IPWR equivalent, key selection criteria include its 14-pin TSSOP package, absence of ADC or USI peripherals (distinguishing it from F20x2/F20x3 variants), verified 1 µs wake-up from standby, and confirmed comparator-based slope A/D capability in embedded signal conditioning.
Technical Context
The MSP430F2001IPWR implements a 16-bit RISC CPU with seven addressing modes and constant generators for high code efficiency. Its basic clock module delivers ACLK (from internal LF oscillator or external 32-kHz crystal), MCLK (DCO-derived up to 16 MHz), and SMCLK - all software-configurable across five low-power modes.
It features a single 8-bit I/O port (P1) with individually programmable pullup/pulldown resistors and edge-selectable interrupts on all eight pins, plus two P2 I/O bits (XIN/XOUT). The integrated Comparator_A+ supports eight-channel analog input multiplexing and CAOUT output for slope A/D conversion - no ADC or serial interface is present.

Applications
| Wireless Sensor Node Front End | Portable Battery-Powered Meter |
|---|---|
Use Scenario: Standalone RF sensor node measuring temperature, humidity, or light and transmitting data via sub-GHz transceiver. IC Role / Device Role / Timing Role: MSP430F2001IPWR acts as signal conditioner and controller - reads analog sensors via comparator-based slope A/D, manages sleep/wake cycles, and interfaces with RF IC over GPIO. Use Value: Ultra-low standby current (0.5 µA) extends coin-cell battery life to >5 years; fast wake-up (<1 µs) ensures responsive event capture without missing sensor transitions. |
Use Scenario: Handheld multimeter or environmental monitor with LCD display and push-button interface. IC Role / Device Role / Timing Role: MSP430F2001IPWR serves as main controller - drives LCD segments, scans buttons, performs analog comparisons for range selection, and manages power sequencing. Use Value: Integrated comparator eliminates external op-amp/comparator components; 1.8–3.6 V operation matches single alkaline or lithium primary cell voltage profile. |
| Industrial Process Monitor | Smart Building Occupancy Detector |
Use Scenario: DIN-rail mounted device monitoring voltage/current thresholds in HVAC or lighting control panels. IC Role / Device Role / Timing Role: MSP430F2001IPWR functions as analog watchdog - continuously compares scaled AC line signals against reference levels using Comparator_A+, triggers alerts on deviation. Use Value: Brownout detector ensures reliable reset during supply dips; –40°C to +85°C rating supports uncontrolled industrial cabinet environments. |
Use Scenario: Passive infrared (PIR) motion detector with adjustable sensitivity and timed output pulse generation. IC Role / Device Role / Timing Role: MSP430F2001IPWR processes PIR sensor output via comparator hysteresis, implements debounce logic, and generates precise ON-time pulses using Timer_A. Use Value: Two capture/compare registers enable independent timing of detection window and output pulse width; low active current minimizes self-heating in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power comparator-based microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2011IPWR | 2KB Flash + 256B info memory, otherwise identical peripheral set and pinout | Required when firmware exceeds 1KB or calibration data storage needs exceed 256B info memory | Select MSP430F2011IPWR if future firmware expansion or factory calibration storage is needed - same footprint and code compatibility |
| MSP430F2002IPWR | Adds 10-bit ADC10 (8 channels, 200 kSPS) and USI (SPI/I²C); removes comparator output functionality on P1.3/P1.7 | Suitable for designs requiring digitized analog inputs rather than comparator-based thresholding or slope A/D | Choose MSP430F2002IPWR only when ADC acquisition is mandatory - not a drop-in replacement due to functional and pin behavior differences |
Compared with MSP430F2001IPWR, MSP430F2011IPWR offers scalable code space with zero hardware change, while MSP430F2002IPWR trades comparator flexibility for ADC resolution - making the former ideal for firmware growth and the latter for precision analog digitization.

FAQ
What is the maximum operating frequency of the MSP430F2001IPWR?
The MSP430F2001IPWR supports an internal digitally controlled oscillator (DCO) calibrated to four frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz - all within ±1% accuracy. It does not require an external crystal to achieve 16 MHz operation, enabling compact, low-BOM designs. The CPU executes instructions at 62.5 ns per cycle at 16 MHz.
Does the MSP430F2001IPWR include an analog-to-digital converter (ADC)?
No, the MSP430F2001IPWR does not include an ADC. It features only the Comparator_A+ module, which supports slope A/D conversion when paired with an external RC network and Timer_A - a technique documented in TI application reports. For integrated ADC functionality, consider the MSP430F2002IPWR (10-bit) or MSP430F2003IPWR (16-bit sigma-delta).
What debug interface does the MSP430F2001IPWR support?
The MSP430F2001IPWR uses the Spy-Bi-Wire (SBW) interface - a two-wire variant of JTAG - implemented on RST/NMI/SBWTDIO and TEST/SBWTCK pins. This allows full in-circuit programming, real-time emulation, and breakpoint debugging without requiring a 4-pin JTAG header, reducing board space and connector cost.
Can the MSP430F2001IPWR drive an LCD directly?
No, the MSP430F2001IPWR lacks built-in LCD driver peripherals. It provides only general-purpose I/O (P1.x and P2.x) and cannot generate the required bias voltages or multiplexed segment/backplane waveforms. For LCD applications, TI recommends the MSP430F4xx or MSP430FRxx families with integrated LCD controllers.
Is the MSP430F2001IPWR pin-compatible with other MSP430F20xx devices in TSSOP packages?
Yes, all MSP430F20xx devices in the 14-pin TSSOP (PW) package share identical pinouts and electrical characteristics - including MSP430F2001IPWR, MSP430F2011IPWR, MSP430F2002IPWR, and MSP430F2012IPWR. However, peripheral availability (e.g., ADC, USI, comparator outputs) differs, so firmware and schematic design must align with the specific variant's capabilities.
