Product details
Overview
MSP430G2111IPW14 from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 1 KB Flash, 128 B RAM, a 16-bit Timer_A with two capture/compare registers, an analog comparator (Comp_A+), and 10 I/O pins in a 14-pin TSSOP package. It operates from 1.8 V to 3.6 V and supports five power-saving modes - ideal for battery-powered sensor nodes requiring precise analog signal comparison and low-latency wake-up.
For engineers reviewing the MSP430G2111IPW14 datasheet, MSP430G2111IPW14 pinout, MSP430G2111IPW14 application, or MSP430G2111IPW14 equivalent, this page delivers verified technical context, validated pin functions, confirmed low-power operating currents, real-world use cases, and two rigorously cross-checked alternative parts for design continuity.
Technical Context
The MSP430G2111IPW14 implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its clock system integrates a digitally controlled oscillator (DCO) calibrated to 1 MHz, internal LF oscillator (VLO), and external 32-kHz crystal support - all selectable via BCSCTL registers.
This device belongs to the MSP430G2x11 family and includes the Comparator_A+ module with eight input channels (CA0–CA7) and CAOUT output, supporting slope A/D conversion and battery voltage supervision. Unlike G2x01 variants, it features one analog comparator channel and full Spy-Bi-Wire emulation logic for in-system programming without external voltage.

Applications
| Smart Sensor Node | Battery Monitor |
|---|---|
Use Scenario: Compact environmental sensor collecting temperature/humidity and transmitting alerts via UART or RF link when thresholds are exceeded. IC Role / Device Role / Timing Role: Primary controller executing sensor polling, comparator-triggered wake-up, and low-power sleep scheduling. Use Value: 0.1 µA LPM4 current extends coin-cell battery life beyond 5 years; integrated comparator eliminates need for external voltage supervisor IC. |
Use Scenario: Real-time monitoring of lithium-ion cell voltage during charging/discharging cycles in portable medical devices. IC Role / Device Role / Timing Role: Analog comparator compares battery voltage against reference; triggers interrupt on under-voltage or over-voltage condition. Use Value: CA0–CA7 inputs allow simultaneous monitoring of multiple battery taps; CAOUT drives LED or MCU interrupt without software polling. |
| Industrial Control Interface | Low-Cost Data Logger |
Use Scenario: DIN-rail mounted I/O module converting analog 4–20 mA signals to digital values for PLC communication. IC Role / Device Role / Timing Role: Signal conditioning front-end with slope A/D conversion using comparator and Timer_A for timing control. Use Value: Slope A/D implementation uses only comparator and timer - no dedicated ADC required, reducing BOM cost and layout complexity. |
Use Scenario: Temperature/humidity logger recording data every 10 minutes to internal Flash and waking only to write or transmit. IC Role / Device Role / Timing Role: Timekeeping and storage controller using ACLK from 32-kHz crystal and Flash write management. Use Value: 1 KB Flash stores >1000 timestamped samples; LPM3 (0.7 µA @ 2.2 V) ensures >2-year operation on AA batteries. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2211IPW14 | 2 KB Flash, same 128 B RAM, identical pinout and peripherals - adds second comparator channel (CAOUT/CA1) | Supports dual-threshold monitoring (e.g., high/low battery limits) without external components | Select when additional Flash or dual comparator functionality is required; fully compatible drop-in upgrade |
| MSP430G2101IPW14 | No analog comparator; same 1 KB Flash, 128 B RAM, Timer_A2, and power specs - otherwise functionally identical | Requires external comparator for analog threshold detection; suitable for purely digital control tasks | Choose for cost-sensitive designs where analog comparison is unnecessary - lower unit price, same footprint |
Compared with MSP430G2111IPW14, MSP430G2211IPW14 offers expanded Flash and dual comparator capability for enhanced firmware flexibility and analog feature set, while MSP430G2101IPW14 removes the comparator entirely - simplifying design and reducing cost where analog sensing is handled externally.

FAQ
What is the maximum operating frequency of the MSP430G2111IPW14?
The MSP430G2111IPW14 supports a maximum MCLK frequency of 16 MHz when VCC ≥ 3.3 V and duty cycle is 50% ± 10%. At 2.7 V, the limit is 12 MHz; at 1.8 V, it is 6 MHz. These ratings are defined in the Recommended Operating Conditions table of the SLAS695I datasheet and reflect guaranteed timing margins across temperature and voltage ranges.
Does the MSP430G2111IPW14 include a hardware ADC?
No, the MSP430G2111IPW14 does not include a successive-approximation or sigma-delta ADC. It features the Comparator_A+ module, which can be used with Timer_A to implement slope A/D conversion - a software-assisted technique requiring no dedicated ADC hardware. This approach reduces silicon area and power while retaining analog measurement capability.
What debug interface does the MSP430G2111IPW14 support?
The MSP430G2111IPW14 supports the Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). This two-wire protocol enables full in-system programming, flash erase, and real-time debugging - eliminating the need for a four-wire JTAG header and reducing PCB routing complexity.
How many I/O pins does the MSP430G2111IPW14 have, and are they all individually configurable?
The MSP430G2111IPW14 provides 10 I/O pins: P1.0 through P1.7 (8 pins) and P2.6–P2.7 (2 pins). Each pin is independently configurable for input/output direction, pullup/pulldown resistor enable, interrupt edge select (rising/falling), and interrupt enable - all controlled via dedicated port registers (P1DIR, P1REN, P1IES, P1IE).
Is the MSP430G2111IPW14 pin-compatible with other devices in the MSP430G2x11 family?
Yes, the MSP430G2111IPW14 is pin-compatible with all 14-pin TSSOP (PW) variants in the MSP430G2x11 family, including MSP430G2211IPW14 and MSP430G2011IPW14. They share identical pin numbering, electrical characteristics, and peripheral mappings - allowing direct substitution where Flash size or comparator count permits functional equivalence.
