Texas Instruments MSP430F2011TRSAT

Overview

MSP430F2011TRSAT 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 requiring analog signal acquisition, timing control, and minimal power consumption.

For engineers reviewing the MSP430F2011TRSAT datasheet, MSP430F2011TRSAT pinout, MSP430F2011TRSAT application, or MSP430F2011TRSAT equivalent, key selection criteria include its TSSOP-14 package, integrated Spy-Bi-Wire debug interface, brownout detection, five low-power modes, and compatibility with 32-kHz crystal or internal DCO clock sources.

Technical Context

The MSP430F2011TRSAT belongs to the MSP430F20x1 family and implements a 16-bit RISC CPU with constant generators for high code efficiency. Its basic clock module delivers ACLK (from 32-kHz crystal or internal LF oscillator), MCLK (system clock), and SMCLK (peripheral clock), with factory-calibrated DCO frequencies up to 16 MHz ±1%.

It integrates on-chip emulation logic via Spy-Bi-Wire (2-wire JTAG), eliminating need for external programming voltage. The device includes a versatile analog comparator with 8-channel input multiplexer and CAOUT output, but no ADC or USI - distinguishing it from MSP430F20x2/x3 variants.

FAQ

What is the maximum operating frequency of the MSP430F2011TRSAT?

The MSP430F2011TRSAT supports a digitally controlled oscillator (DCO) with factory-calibrated frequencies up to 16 MHz ±1%. While the CPU executes instructions at 62.5-ns cycle time (16 MIPS theoretical), actual sustained operation depends on supply voltage and temperature; at 3.3 V, 16 MHz is fully supported per datasheet specifications. The MSP430F2011TRSAT does not require external crystal for full-speed operation due to internal DCO calibration.

Does the MSP430F2011TRSAT include an analog-to-digital converter (ADC)?

No, the MSP430F2011TRSAT does not include an ADC. It belongs to the MSP430F20x1 family, which features an analog comparator but no ADC. This distinguishes it from the MSP430F20x2 (10-bit ADC10) and MSP430F20x3 (16-bit SD16_A sigma-delta ADC) variants. The MSP430F2011TRSAT uses its comparator for slope A/D conversion or threshold detection instead of dedicated ADC hardware.

What debug interface does the MSP430F2011TRSAT support?

The MSP430F2011TRSAT supports Spy-Bi-Wire (SBW), a 2-pin variant of JTAG implemented via RST/NMI/SBWTDIO and TEST/SBWTCK pins. This interface enables full in-system programming, flash erasure, breakpoint debugging, and register inspection without requiring a 4-pin JTAG header. The MSP430F2011TRSAT does not support standard 4-wire JTAG; SBW is its sole debug mechanism.

What package type and pin count does the MSP430F2011TRSAT use?

The MSP430F2011TRSAT is packaged in a 14-pin Plastic Thin Shrink Small-Outline Package (TSSOP), designated by the 'T' suffix in the part number and confirmed by TI's SLAS491I datasheet. It measures 5.0 mm × 4.4 mm × 1.2 mm and is RoHS-compliant. This package is pin-compatible with other MSP430F20xx devices in TSSOP-14, including MSP430F2001IPW and MSP430F2012IPW.

How does the MSP430F2011TRSAT achieve ultra-low-power operation?

The MSP430F2011TRSAT achieves ultra-low-power operation through five software-selectable low-power modes (LPM0–LPM4), sub-1 µs wake-up from standby, and optimized circuit design. In LPM4 (lowest power), it draws just 0.1 µA while retaining RAM contents. Active-mode current is 220 µA at 1 MHz/2.2 V. Its digitally controlled oscillator (DCO) stabilizes rapidly, avoiding long crystal startup delays that increase energy per wakeup cycle - a key advantage in duty-cycled sensor applications using MSP430F2011TRSAT.
