Texas Instruments MSP430F2011TPWR

Overview

MSP430F2011TPWR 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 (0.5 µA). It targets battery-powered sensor nodes requiring analog signal conditioning, timing control, and minimal power budget.

For engineers reviewing the MSP430F2011TPWR datasheet, MSP430F2011TPWR pinout, MSP430F2011TPWR application, or MSP430F2011TPWR equivalent, key selection criteria include its 14-pin TSSOP package, absence of integrated ADC or USI (unlike F20x2/F20x3 variants), presence of analog comparator_A+, and compatibility with Spy-Bi-Wire programming and brownout detection.

Technical Context

The MSP430F2011TPWR 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.

It features five software-selectable low-power modes (LPM0–LPM4), with LPM4 consuming only 0.1 µA (RAM retention). The analog comparator_A+ provides eight-channel input multiplexing, rail-to-rail operation, and output routing to P1.3 or P1.7 - critical for threshold detection and slope A/D conversion without ADC hardware.

FAQ

What is the maximum operating frequency of the MSP430F2011TPWR?

The MSP430F2011TPWR supports internal DCO frequencies up to 16 MHz, factory-calibrated to ±1% accuracy at 1 MHz, 8 MHz, 12 MHz, and 16 MHz. External clock sources (e.g., 32-kHz crystal or digital clock) may also drive ACLK or MCLK, but the DCO remains the primary high-speed system clock source. MSP430F2011TPWR achieves full performance across its 1.8 V–3.6 V supply range at these frequencies.

Does the MSP430F2011TPWR include an analog-to-digital converter (ADC)?

No, the MSP430F2011TPWR does not integrate an ADC. It belongs to the MSP430F20x1 family variant, which features the analog comparator_A+ but omits both the 10-bit ADC10 (found in F20x2) and the 16-bit SD16_A sigma-delta converter (found in F20x3). Analog signal digitization must be implemented externally or via slope A/D techniques using the comparator and Timer_A.

Which debug interface does the MSP430F2011TPWR support?

The MSP430F2011TPWR supports the Spy-Bi-Wire (SBW) interface using two pins: RST/NMI/SBWTDIO and TEST/SBWTCK. This two-wire protocol enables full in-system programming, flash erasure, and real-time emulation without requiring a full 4-pin JTAG header. SBW is fully compatible with TI's MSP-FET and IAR Embedded Workbench toolchains.

What is the purpose of the CAOUT pin on the MSP430F2011TPWR?

The CAOUT function appears on P1.3 and P1.7 of the MSP430F2011TPWR and serves as the output of the integrated analog comparator_A+. It can be configured as open-drain or push-pull, and its polarity is software-selectable. This pin enables direct connection to interrupt inputs or external logic, allowing hardware-accelerated threshold detection without CPU polling or ADC conversion.

Is the MSP430F2011TPWR pin-compatible with other MSP430F20xx devices in TSSOP packages?

Yes, the MSP430F2011TPWR shares identical pinout and electrical characteristics with all MSP430F20xx devices offered in the 14-pin TSSOP (PW) package, including MSP430F2001TPWR, MSP430F2012TPWR, and MSP430F2013TPWR. However, peripheral availability differs: F2011 lacks ADC10 and USI found in F2012/F2013, and uses comparator_A+ instead of ADC inputs on shared pins.
