Product details
Overview
MSP430F2011TPW from Texas Instruments is an ultra-low-power 16-bit 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 at 1 MHz/2.2 V in active mode, and supports sub-1 µs wake-up from standby mode. It targets battery-powered sensor nodes and portable measurement systems requiring analog signal acquisition and low-energy processing.
For engineers reviewing the MSP430F2011TPW datasheet, MSP430F2011TPW pinout, MSP430F2011TPW application, or MSP430F2011TPW equivalent, key selection criteria include its TSSOP-14 package, integrated comparator (MSP430F20x1 family), Spy-Bi-Wire debug interface, and -40°C to 105°C temperature grade - all confirmed for this exact part number.
Technical Context
The MSP430F2011TPW implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at 1 MHz, 8 MHz, 12 MHz, and 16 MHz, plus internal low-frequency and external crystal (32 kHz) support.
This device belongs to the MSP430F20x1 variant group and includes an on-chip analog comparator with eight-channel input multiplexing (CA0–CA7), but no ADC or USI peripheral. It supports five power-saving modes (LPM0–LPM4), with off-mode current of 0.1 µA and standby-mode current of 0.5 µA - all verified for MSP430F2011TPW per SLAS491I Rev. I.

| P1.1/TA0/CA1 | Port 1 bit 1 / Timer_A capture/compare 0 / Comparator_A+ input 1 | Supports edge-triggered event capture or PWM generation; dual-use analog input for comparator |
| P1.2/TA1/CA2 | Port 1 bit 2 / Timer_A capture/compare 1 / Comparator_A+ input 2 | Enables second independent timing channel or differential analog comparison |
| P1.3/CAOUT/CA3 | Port 1 bit 3 / Comparator_A+ output / input 3 | Direct comparator output accessible without software read; configurable as analog input |
| P1.4/SMCLK/CA4/TCK | Port 1 bit 4 / Sub-main clock output / Comparator_A+ input 4 / JTAG test clock | Drives peripheral clocks; shares pin with debug interface - requires careful mode sequencing |
| P1.5/TA0/CA5/TMS | Port 1 bit 5 / Timer_A capture/compare 0 / Comparator_A+ input 5 / JTAG test mode select | Shared function pin - TMS must be held stable during debug; TA0 and CA5 are mutually exclusive |
| P1.6/TA1/CA6/TDI/TCLK | Port 1 bit 6 / Timer_A capture/compare 1 / Comparator_A+ input 6 / JTAG test data input/clock | Multi-role pin supporting both timing and debug; TDI/TCLK selection controlled by JTAG instruction |

| TEST/SBWTCK | Test mode select / Spy-Bi-Wire clock | Activates JTAG/Spy-Bi-Wire; tied to security fuse - permanent write-protection if blown |
| VCC | Power supply | 1.8–3.6 V digital/analog supply; decoupling required within 10 mm of pin |
| VSS | Ground reference | Common return for all analog/digital circuits; must connect to low-impedance ground plane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2001TPW | 1KB+256B flash, same comparator and pinout; lacks Timer_A compare register CCR1 | Lower code density requirement; suitable for simpler state machines without dual PWM or capture channels | Select when firmware fits in 1KB and only one Timer_A compare channel is needed |
| MSP430F2012TPW | Includes 10-bit ADC10 (8-channel, 200 kSPS) and USI (SPI/I²C); replaces comparator with ADC inputs | Requires analog-to-digital conversion instead of threshold comparison; adds serial communication capability | Choose when system needs digitized sensor data or host connectivity - not a drop-in replacement |
Compared with MSP430F2001TPW, the MSP430F2011TPW provides double flash capacity and full Timer_A2 functionality; compared with MSP430F2012TPW, it trades ADC and USI for lower power and comparator-centric analog processing - making it optimal for threshold-triggered, ultra-low-energy sensing.

FAQ
What is the maximum operating frequency of the MSP430F2011TPW?
The MSP430F2011TPW 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 revision I, Table 11, and applies directly to the MSP430F2011TPW across its full temperature range (-40°C to +105°C).
Does the MSP430F2011TPW include an analog-to-digital converter (ADC)?
No, the MSP430F2011TPW does not include an ADC. It belongs to the MSP430F20x1 family, which features an on-chip analog comparator (Comparator_A+) but no ADC. Devices like MSP430F2012TPW (F20x2) and MSP430F2013TPW (F20x3) add ADC10 and SD16_A respectively - confirmed by functional block diagrams and terminal function tables in SLAS491I.
What debug interface does the MSP430F2011TPW support?
The MSP430F2011TPW supports the Spy-Bi-Wire (SBW) interface using two pins: RST/NMI/SBWTDIO and TEST/SBWTCK. It does not support full 4-wire JTAG. This is explicitly stated in the "Features" section and validated by pin function tables for MSP430F20x1 in SLAS491I, where TDI/TDO/TMS/TCK appear only in F20x2/F20x3 variants.
Is the MSP430F2011TPW pin-compatible with other MSP430F20xx devices in TSSOP-14?
Yes, the MSP430F2011TPW shares identical pinout and electrical characteristics with other TSSOP-14 MSP430F20xx devices (e.g., MSP430F2001TPW, MSP430F2012TPW) per Table 1 and pinout diagrams in SLAS491I. However, peripheral differences (e.g., ADC presence, comparator vs. USI) mean firmware and schematic design must match the specific variant's capabilities.
What is the purpose of the CAOUT pin on the MSP430F2011TPW?
The CAOUT pin (P1.3 and P1.7) provides the analog output of the on-chip Comparator_A+. It delivers the raw comparator decision signal - high when CA+ > CA−, low otherwise - enabling direct connection to GPIO-interrupt logic or external circuitry without software polling. This function is documented in Table 2 (MSP430F20x1 Terminal Functions) of SLAS491I.
