Product details
Overview
MSP430F2002IPW from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with 1KB Flash, 128B RAM, and integrated Timer_A, comparator, and Spy-Bi-Wire debug interface - designed for battery-powered sensor nodes and portable measurement systems operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F2002IPW datasheet, MSP430F2002IPW pinout, MSP430F2002IPW application, or MSP430F2002IPW equivalent, this page delivers verified specifications, TSSOP-14 package mapping, functional pin roles, low-power mode behavior, and direct alternative part comparisons grounded in TI's SLAS491I datasheet.
Technical Context
The MSP430F2002IPW implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations at up to 16 MHz via its digitally controlled oscillator (DCO). It supports five software-selectable low-power modes, including LPM4 with 0.1 µA off-mode current and sub-1 µs wake-up from standby.
Its peripheral set includes a 16-bit Timer_A2 with two capture/compare registers, an analog comparator with eight-channel input multiplexing, brownout detection, and on-chip emulation logic. The device lacks ADC or USI modules - distinguishing it from MSP430F20x2/x3 variants - and relies solely on the comparator for analog signal evaluation.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ACLK/CA0 | Port 1 bit 0 / Timer clock / ACLK output / Comparator_A+ input | Primary timer clock source; also routes ACLK to external circuitry or feeds CA0 for analog comparison |
| P1.1/TA0/CA1 | Port 1 bit 1 / Timer_A CCI0A input / Comparator_A+ input | Enables edge-triggered capture of external signals or analog threshold detection on CA1 |
| P1.2/TA1/CA2 | Port 1 bit 2 / Timer_A CCI1A input / Comparator_A+ input | Supports second capture channel or dual-input comparator configuration (e.g., window detection) |
| P1.3/CAOUT/CA3 | Port 1 bit 3 / Comparator output / CA3 input | Direct comparator output for interrupt generation or external logic; configurable as analog input |
| P1.4/SMCLK/CA4/TCK | Port 1 bit 4 / SMCLK output / CA4 input / JTAG test clock | Provides subsystem clock to peripherals; doubles as JTAG TCK during programming |
| P1.5/TA0/CA5/TMS | Port 1 bit 5 / Timer_A CCI0A output / CA5 input / JTAG TMS | Drives TA0 output (e.g., PWM) or serves as JTAG mode select - shared function requires careful pin mux control |
| P1.6/TA1/CA6/TDI/TCLK | Port 1 bit 6 / Timer_A CCI1A output / CA6 input / JTAG TDI/TCLK | Supports second compare output or dual-role JTAG data/clock - not simultaneously active |
| P1.7/CAOUT/CA7/TDO/TDI | Port 1 bit 7 / Comparator output / CA7 input / JTAG TDO/TDI | Dual comparator output path or JTAG data I/O - selected via JTAG instruction, not hardware mux |

| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / Spy-Bi-Wire data I/O | Single pin handles power-on reset, NMI event, and bidirectional debug communication - no separate SWDIO |
| TEST/SBWTCK | Test mode select / Spy-Bi-Wire clock | Activates JTAG/Spy-Bi-Wire mode; must be held high during programming; tied to security fuse |
| VCC | Power supply | Primary digital/analog supply - no separate AVCC/DVCC rails; decoupling required within 1 cm |
| VSS | Ground reference | Common ground for all analog/digital functions - connects to QFN thermal pad in RSA package |
Key Features
| Feature | Design Value |
|---|---|
| Five Low-Power Modes | LPM0–LPM4 enable dynamic power scaling - LPM4 draws just 0.1 µA while retaining full RAM content |
| Comparator_A+ with 8-Input Mux | Supports voltage window detection, zero-crossing sensing, or slope A/D conversion without external components |
| Digitally Controlled Oscillator (DCO) | Four factory-calibrated frequencies (1/8/12/16 MHz) ±1% accuracy - eliminates need for external crystal in many apps |
| Spy-Bi-Wire Emulation | 2-pin debug interface reduces PCB footprint and BOM count vs. full 4-pin JTAG; supports flash programming and real-time trace |
| Code Protection | Security fuse prevents unauthorized readout of Flash contents - irreversible once blown |
| Integrated Brownout Detector | Ensures reliable reset during power ramp-up/down; threshold fixed at ~1.3 V - no external supervisor needed |

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 |
|---|---|---|---|
| MSP430F2012IPW | 2KB Flash, same 128B RAM, identical peripherals - adds USI (SPI/I²C) and 10-bit ADC10 | Required when sensor data acquisition needs digitization (e.g., thermistor, potentiometer) or host communication via I²C | Select if ADC or serial interface is mandatory; otherwise MSP430F2002IPW offers lower cost and smaller code footprint |
| MSP430F2001IPW | Same 1KB Flash/128B RAM, identical pinout and peripherals - omits Timer_A compare functionality (no Out0/Out1) | Suitable only for basic timing (TACLK/ACLK), capture-only, or comparator-only use cases - no PWM or gated output generation | Choose only when Timer_A compare outputs are unused; MSP430F2002IPW provides full Timer_A2 feature set without cost penalty |
Compared with MSP430F2002IPW, MSP430F2012IPW adds essential analog-to-digital and serial capabilities at higher memory cost, while MSP430F2001IPW removes critical Timer_A compare outputs - making MSP430F2002IPW the optimal balance of analog sensing, timing control, and minimal BOM for resource-constrained embedded designs.

FAQ
What is the maximum operating frequency of the MSP430F2002IPW?
The MSP430F2002IPW supports a maximum CPU clock frequency of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO). This frequency is guaranteed across the full -40°C to +85°C temperature range and 1.8 V to 3.6 V supply, with ±1% accuracy at 25°C per SLAS491I. The DCO requires no external components and stabilizes in under 1 µs.
Does the MSP430F2002IPW include an analog-to-digital converter (ADC)?
No, the MSP430F2002IPW does not include an ADC. It belongs to the MSP430F20x1 family variant, which features only the analog comparator (Comparator_A+) - not the 10-bit ADC10 (found in F20x2) or 16-bit SD16_A (found in F20x3). For analog digitization, external ADC or slope-A/D techniques using the comparator and Timer_A must be implemented.
How many I/O pins does the MSP430F2002IPW provide in the TSSOP-14 package?
The MSP430F2002IPW provides 10 usable I/O pins in the TSSOP-14 (PW) package: eight bits on Port 1 (P1.0–P1.7) and two bits on Port 2 (P2.6/XIN and P2.7/XOUT). All 10 pins support interrupt capability, programmable pullup/pulldown resistors, and multiple peripheral functions - confirmed in Tables 2 and 12 of the SLAS491I datasheet.
Can the MSP430F2002IPW be programmed in-circuit without removing it from the PCB?
Yes, the MSP430F2002IPW supports in-system programming via its Spy-Bi-Wire interface using only two pins: RST/NMI/SBWTDIO and TEST/SBWTCK. No external programming voltage is required - the interface operates directly from the VCC supply. TI's MSP-FET430UIF or compatible debuggers enable full flash erase, program, and verify operations without board removal.
What is the purpose of the CAOUT pin on the MSP430F2002IPW?
The CAOUT pin (P1.3 and P1.7) serves as the output of the integrated Comparator_A+, delivering a digital result of the analog comparison between selected inputs. It can drive external logic, generate interrupts (via P1IFG.3 or P1IFG.7), or feed back into other peripherals - enabling window detection, zero-crossing triggers, or slope A/D conversion when combined with Timer_A.
