Product details
Overview
MSP430F2001IPW from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 1KB flash, 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 MSP430F2001IPW datasheet, MSP430F2001IPW pinout, MSP430F2001IPW application, or MSP430F2001IPW 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 compatibility with TI's MSP430x2xx toolchain and development ecosystem.
Technical Context
The MSP430F2001IPW implements a 16-bit 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), SMCLK, and MCLK - all configurable via software-controlled DCO calibration data stored in flash segment A.
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 analog comparator supports eight-channel input multiplexing and can generate interrupts or drive CAOUT outputs directly - no ADC or serial interface is present.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ACLK/CA0 | Port 1 bit 0 / Timer_A clock input / ACLK output / Comparator_A+ input 0 | Primary timer clock source; also routes low-frequency system clock and analog comparator channel |
| P1.1/TA0/CA1 | Port 1 bit 1 / Timer_A CCI0A input / Comparator_A+ input 1 | Enables capture of external events or comparison against TA0 register; dual-use analog/digital I/O |
| P1.2/TA1/CA2 | Port 1 bit 2 / Timer_A CCI1A input / Comparator_A+ input 2 | Second capture/compare channel; supports slope A/D conversion when paired with CAOUT |
| P1.3/CAOUT/CA3 | Port 1 bit 3 / Comparator_A+ output / input 3 | Drives comparator result directly to GPIO; allows latching or external feedback without CPU intervention |
| P1.4/SMCLK/CA4/TCK | Port 1 bit 4 / SMCLK output / Comparator_A+ input 4 / JTAG test clock | Provides sub-main clock to peripherals; shares pin with debug interface - requires careful pin mux control |
| P1.5/TA0/CA5/TMS | Port 1 bit 5 / Timer_A Out0 / Comparator_A+ input 5 / JTAG test mode select | Output-capable pin for PWM or timing signals; also serves as JTAG control - not usable simultaneously |

| RST/NMI/SBWTDIO | Reset / non-maskable interrupt / Spy-Bi-Wire data I/O | Multi-role pin: resets device, triggers NMI, and handles bidirectional programming/debug data |
| TEST/SBWTCK | Test mode select / Spy-Bi-Wire clock | Activates JTAG/Spy-Bi-Wire interface; tied high during normal operation to disable test mode |
| VCC | Supply voltage | Single 1.8–3.6 V rail powers entire digital and analog circuitry - no separate AVCC/DVCC required |
| VSS | Ground reference | Common return for all circuits; QFN variant uses dedicated DVSS/AVSS, but TSSOP uses shared VSS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2011IPW | 2KB flash, same 128B RAM, identical peripherals and pinout | Supports larger firmware images and more complex state machines without external memory | Select when firmware exceeds 1KB or future scalability is required; drop-in replacement with no layout change |
| MSP430F2002IPW | Adds 10-bit ADC10 (8 channels, 200 kSPS) and USI (SPI/I²C); same flash/RAM | Enables direct digitization of analog sensors and communication with external EEPROM or displays | Choose when analog-to-digital conversion or serial interface is mandatory; requires verifying pin function mapping |
Compared with MSP430F2011IPW, the MSP430F2001IPW trades flash capacity for lower unit cost and smaller die size; compared with MSP430F2002IPW, it omits ADC and USI to reduce power and complexity - making it optimal for comparator-only, minimal-peripheral sensing tasks.

FAQ
What is the maximum operating frequency of the MSP430F2001IPW?
The MSP430F2001IPW supports a maximum system clock (MCLK) of 16 MHz, achieved using the factory-calibrated digitally controlled oscillator (DCO). This frequency is confirmed in the SLAS491I datasheet Section 1 "Features" and Table 11 "DCO Calibration Data", where CALBC1_16MHZ and CALDCO_16MHZ values are provided for 16 MHz operation. The CPU executes instructions at 62.5 ns per cycle at this rate.
Does the MSP430F2001IPW include an analog-to-digital converter (ADC)?
No, the MSP430F2001IPW does not include an ADC. It belongs to the MSP430F20x1 family variant, which features only the analog comparator (Comparator_A+). ADC functionality is present only in the F20x2 (10-bit ADC10) and F20x3 (16-bit SD16_A) variants. This distinction is explicitly stated in the "DESCRIPTION" section of the SLAS491I datasheet and confirmed in Table 1 "Available Options" and functional block diagrams.
Can the MSP430F2001IPW communicate via SPI or I²C?
No, the MSP430F2001IPW lacks a Universal Serial Interface (USI) or any hardware serial peripheral. USI support is exclusive to the MSP430F20x2 and MSP430F20x3 families. The MSP430F2001IPW provides only GPIO, Timer_A, comparator, and Spy-Bi-Wire debug interface - serial communication must be implemented in software (bit-banged) if required.
What package type is used for the MSP430F2001IPW?
The MSP430F2001IPW uses a 14-pin plastic thin-shrink small-outline package (TSSOP), designated "PW" in TI's ordering nomenclature. This is confirmed in Table 1 "Available Options" of the SLAS491I datasheet, which lists "MSP430F2001IPW" under the "PLASTIC 14-PIN TSSOP (PW)" column, and in the "Device Pinout" diagrams labeled "PW or N PACKAGE (TOP VIEW)".
How is programming and debugging performed on the MSP430F2001IPW?
Programming and debugging of the MSP430F2001IPW is performed via the two-wire Spy-Bi-Wire interface using the TEST/SBWTCK and RST/NMI/SBWTDIO pins. This interface replaces standard JTAG to reduce pin count and PCB area. TI's MSP-FET and compatible tools support full flash programming, breakpoint debugging, and real-time register inspection - all documented in the MSP430x2xx Family User's Guide (SLAU144).
