Product details
Overview
MSP430F2002TPW from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller with 1KB Flash + 256B information 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 five power-saving modes - ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2002TPW datasheet, MSP430F2002TPW pinout, MSP430F2002TPW application, or MSP430F2002TPW equivalent, key selection criteria include its TSSOP-14 package, integrated USI (SPI/I²C), 10-bit 200-ksps ADC with autoscan, brownout detection, and Spy-Bi-Wire on-chip emulation - all within a -40°C to 105°C industrial temperature grade.
Technical Context
The MSP430F2002TPW belongs to the MSP430F20x2 family and integrates a 16-bit Timer_A2 module with two capture/compare registers, supporting PWM generation, interval timing, and input capture. Its clock system includes a digitally controlled oscillator (DCO) calibrated to ±1% at four frequencies up to 16 MHz, plus support for external 32-kHz crystal or digital clock sources.
It features a Universal Serial Interface (USI) configurable for SPI or I²C communication, a 10-bit ADC with internal reference, sample-and-hold, and autoscan across eight analog inputs, and a brownout detector with reset capability. All I/O pins are individually configurable with programmable pullup/pulldown resistors and edge-selectable interrupts.
Key Specifications

Pinout & Package
Package: 14-pin TSSOP (PW), 5.0 mm × 4.4 mm, 0.65 mm pitch, surface-mount. Pinout validated per TI SLAS491I Rev. I (December 2012), Table 3 (MSP430F20x2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ACLK/A0 | Timer/ADC input & clock source | Configurable as Timer_A clock input (TACLK), auxiliary clock output (ACLK), or ADC channel A0 - enables flexible timing and analog acquisition routing. |
| P1.1/TA0/A1 | Timer capture/compare & ADC input | Supports CCI0A capture or Out0 compare output, and serves as ADC input A1 - allows synchronized event-triggered sampling or PWM-driven actuation. |
| P1.2/TA1/A2 | Timer capture/compare & ADC input | Provides CCI1A capture or Out1 compare, and ADC channel A2 - enables dual-signal monitoring (e.g., differential pair or phase-aligned sensing). |
| P1.3/ADC10CLK/A3/VREF− | ADC clock & reference input | Outputs ADC conversion clock (ADC10CLK), accepts analog input A3, and provides negative reference (VREF−) - simplifies precision ratiometric measurements. |
| P1.4/SMCLK/A4/VREF+ | System clock & ADC reference | Outputs sub-main clock (SMCLK) for peripherals, accepts ADC input A4, and supplies positive reference (VREF+) - supports self-referenced analog front-end design. |
| RST/NMI/SBWTDIO | Reset & debug I/O | Combines reset/NMI functionality with Spy-Bi-Wire data I/O; enables single-pin debug access and robust system recovery under fault conditions. |
| TEST/SBWTCK | Debug clock input | Dedicated Spy-Bi-Wire test clock; ensures reliable programming and debugging without sharing signals with application I/O. |
| VCC / VSS | Power supply terminals | Single-supply operation (1.8–3.6 V); VSS serves as common ground reference for digital and analog domains - requires local decoupling per layout guidelines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2012TPW | 2KB Flash + 256B info memory, same peripherals and pinout - doubles program space without layout change. | Required when firmware exceeds 1KB or needs additional calibration tables in info memory. | Select for future-proofing or complex sensor fusion algorithms requiring >1KB code space. |
| MSP430G2553IPW28 | 28-pin TSSOP, 16KB Flash, 512B RAM, enhanced USI, but no factory DCO calibration; higher active current (270 µA @ 1 MHz). | Used where larger memory, more I/O, or USB-capable variants (e.g., G2553IRHB) are needed - not drop-in compatible. | Choose only if pin count, memory, or peripheral expansion outweighs strict ultra-low-power requirements. |
Compared with MSP430F2012TPW, the MSP430F2002TPW trades Flash capacity for lower cost and smaller footprint while retaining identical analog/peripheral performance; versus MSP430G2553IPW28, it offers superior power efficiency and factory-trimmed DCO stability at the expense of scalability.

FAQ
What is the maximum operating frequency of the MSP430F2002TPW?
The MSP430F2002TPW supports an internal digitally controlled oscillator (DCO) calibrated to four frequencies up to 16 MHz. While the core executes instructions at 62.5-ns cycle time (16 MIPS theoretical), actual system clock (MCLK) is typically configured up to 16 MHz per factory calibration data in Flash Segment A - confirmed in SLAS491I Table 11.
Does the MSP430F2002TPW support hardware I²C communication?
Yes, the MSP430F2002TPW includes a Universal Serial Interface (USI) module that supports both SPI and I²C protocols in hardware. As documented in SLAS491I Section 1, USI provides dedicated I²C clock (SCL) and data (SDA) lines on P1.6 and P1.7 respectively - enabling standard two-wire communication without CPU bit-banging.
What is the purpose of the TEST/SBWTCK pin on the MSP430F2002TPW?
The TEST/SBWTCK pin on the MSP430F2002TPW serves as the dedicated Spy-Bi-Wire test clock input for programming and debugging. As specified in Table 3 of SLAS491I, it enables 2-wire JTAG access using only TEST and RST/NMI/SBWTDIO - reducing debug footprint versus full 4-pin JTAG while supporting flash programming and real-time emulation.
Can the MSP430F2002TPW operate from a single 1.8 V supply?
Yes, the MSP430F2002TPW is fully specified to operate across 1.8 V to 3.6 V supply range. Its ultra-low-power architecture maintains full functionality - including 10-bit ADC operation, USI communication, and Timer_A - at 1.8 V, as verified in the "Low Supply Voltage Range" feature list and electrical characteristics section of SLAS491I.
How many analog input channels does the MSP430F2002TPW ADC support?
The MSP430F2002TPW integrates a 10-bit ADC with autoscan capability across eight analog input channels (A0–A7), as explicitly defined in Table 3 (Terminal Functions, MSP430F20x2) and Section 1 features. These channels are mapped to P1.0 through P1.7, with dedicated reference inputs (VREF+/VREF−) on P1.3 and P1.4.
