Product details
Overview
MSP430F2011IPW 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, achieves active-mode current of 220 µA at 1 MHz/2.2 V, and supports five power-saving modes including sub-1 µs wake-up from standby - ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2011IPW datasheet, MSP430F2011IPW pinout, MSP430F2011IPW application, or MSP430F2011IPW equivalent, this page delivers verified technical context, exact pin functions for TSSOP-14 packaging, confirmed low-power operating modes, and validated alternative options for cost- or feature-sensitive designs.
Technical Context
The MSP430F2011IPW belongs to the MSP430F20x1 family and 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 lacks ADC and USI peripherals - distinguishing it from MSP430F20x2/x3 variants - and instead features an analog comparator with eight-channel input multiplexing (CA0–CA7), comparator output routing (CAOUT), and integrated Spy-Bi-Wire debug interface. All I/O pins on Port P1 support individually configurable pullup/pulldown resistors and edge-selectable interrupts.

FAQ
What is the maximum operating frequency of the MSP430F2011IPW?
The MSP430F2011IPW supports a maximum CPU clock frequency of 16 MHz via its factory-calibrated digitally controlled oscillator (DCO). This frequency is achieved using the CALDCO_16MHZ and CALBC1_16MHZ values stored in flash information memory segment A. The DCO stabilizes in less than 1 µs, enabling rapid transitions from low-power modes to full-speed execution without external crystal dependency.
Does the MSP430F2011IPW include an analog-to-digital converter (ADC)?
No, the MSP430F2011IPW does not include an ADC. It belongs to the MSP430F20x1 family, which features an analog comparator (Comparator_A+) but omits the ADC10 module found in MSP430F20x2 and the SD16_A sigma-delta ADC in MSP430F20x3. For designs requiring digitized analog signals, the MSP430F2012IPW (with 10-bit ADC10) or MSP430F2013IPW (with 16-bit SD16_A) are functionally differentiated alternatives.
What debug interface does the MSP430F2011IPW support?
The MSP430F2011IPW supports the Spy-Bi-Wire (SBW) interface using two dedicated pins: RST/NMI/SBWTDIO and TEST/SBWTCK. This two-wire protocol replaces standard 4-pin JTAG, reducing PCB footprint and connector cost while enabling full flash programming, real-time debugging, and breakpoint execution. No external debugger hardware beyond TI's MSP-FET or compatible tools is required.
Can the MSP430F2011IPW operate from a single 1.8 V supply?
Yes, the MSP430F2011IPW is fully specified to operate across a supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains functional operation including flash programming, comparator accuracy, and all five low-power modes. Active-mode current increases slightly to ~250 µA at 1 MHz, but standby remains at 0.5 µA - making it suitable for energy-harvesting or coin-cell applications where minimum voltage headroom is critical.
How is flash memory protected against unauthorized access on the MSP430F2011IPW?
Flash protection on the MSP430F2011IPW is enforced by a one-time programmable security fuse. When blown, this fuse disables read access to main and information flash memory via Spy-Bi-Wire or JTAG, preventing firmware extraction. The fuse does not affect normal program execution or erase/write operations - only debug readout. Calibration data in flash segment A remains accessible post-fuse blow, preserving DCO accuracy.
