Product details
Overview
MSP430G2101IPW14 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, internal DCO clock up to 16 MHz, and 10 general-purpose I/O pins in a 14-pin TSSOP package-designed for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2101IPW14 datasheet, MSP430G2101IPW14 pinout, MSP430G2101IPW14 application, or MSP430G2101IPW14 equivalent, this page delivers verified technical context, exact pin functions, low-power mode behavior, real-world use cases, and validated alternative options for embedded design and sourcing decisions.
Technical Context
The MSP430G2101IPW14 implements a 16-bit RISC CPU with constant generators, seven addressing modes, and register-to-register execution in one CPU cycle. It integrates a basic clock module with internal DCO (calibrated to 1 MHz, scalable to 16 MHz), LF oscillator, and 32-kHz crystal support-enabling sub-1 µs wake-up from LPM4.
Its peripheral set includes Timer_A2 (16-bit, two CC registers), brownout detector, watchdog timer+, Spy-Bi-Wire emulation interface, and digital I/O across Port P1 (8 bits) and Port P2 (2 bits), all operating within 1.8–3.6 V supply range and five software-selectable low-power modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and 51-instruction set; enables efficient C code execution and deterministic timing control. |
| Flash / RAM | 1 kB flash memory (512-byte segments) and 128 B RAM; supports in-system programming via Spy-Bi-Wire without external voltage. |
| Operating Voltage | 1.8 V to 3.6 V; allows direct integration with coin-cell (e.g., CR2032) and single Li-ion battery systems. |
| Active Current | 220 µA at 1 MHz, 2.2 V; enables multi-year operation in duty-cycled sensor applications with sub-1% active time. |
| Low-Power Modes | LPM4 draws 0.1 µA (RAM retention); supports ultra-long sleep intervals between wake-up events triggered by I/O or timer interrupts. |
| Timer Resource | Timer_A2 with two capture/compare registers (TA0.0, TA0.1); provides PWM generation, input capture, and interval timing without external components. |
| Package | 14-pin TSSOP (PW); 5.0 × 4.4 mm footprint compatible with automated SMT assembly and space-constrained PCB layouts. |
Pinout & Package
Package: 14-pin Plastic Small-Outline Thin (TSSOP), PW variant. Body dimensions: 5.0 mm × 4.4 mm × 1.2 mm. Lead pitch: 0.65 mm. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DVCC) | Power supply | Positive supply rail (1.8–3.6 V); must be decoupled with 100 nF ceramic capacitor near pin. |
| 14 (DVSS) | Ground reference | Digital ground return; requires low-impedance connection to system GND plane. |
| 10 (RST/NMI/SBWTDIO) | Reset & debug I/O | Active-low reset input; also serves as bidirectional Spy-Bi-Wire data line for programming and debugging. |

| P2.6–P2.7 | General-purpose I/O | 2-bit Port P2; P2.6 supports TA0.1 output; P2.7 is XOUT for crystal oscillator or general I/O. |
| XIN/P2.6 | Clock input | Crystal oscillator input or external clock source; requires 32.768 kHz tuning fork crystal for RTC functionality. |
| XOUT/P2.7 | Clock output | Oscillator output; drives external crystal; can be repurposed as GPIO when crystal not used. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2211IPW14 | Includes Comparator_A+ module (8-channel analog comparator); same 1 kB flash, 128 B RAM, and 14-pin TSSOP package. | Required for slope A/D conversion, battery voltage supervision, or analog threshold detection without external op-amps. | Select when analog comparison or precision voltage monitoring is needed; otherwise, MSP430G2101IPW14 offers lower cost and identical digital functionality. |
| MSP430G2102IPW14 | Adds USCI_A0 (UART/SPI/I²C) peripheral; retains same flash/RAM, voltage range, and low-power specs. | Necessary for serial communication with displays, sensors, or host controllers-MSP430G2101IPW14 lacks hardware UART or SPI. | Choose when protocol-based connectivity is essential; MSP430G2101IPW14 remains optimal for pure GPIO/timer-based control with minimal BOM count. |
Compared with MSP430G2211IPW14 and MSP430G2102IPW14, the MSP430G2101IPW14 delivers the lowest gate count and bill-of-materials cost for applications requiring only digital I/O, basic timing, and ultra-low quiescent current-making it ideal for high-volume, price-sensitive sensor endpoints where analog or serial interfaces are unnecessary.

FAQ
What is the maximum operating frequency of the MSP430G2101IPW14?
The MSP430G2101IPW14 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 drops to 12 MHz, and at 1.8 V, it is 6 MHz. These values are specified in the Recommended Operating Conditions table of the SLAS695I datasheet and reflect guaranteed timing margins-not typical or peak performance under marginal conditions. The internal DCO is factory-calibrated for 1 MHz but can be reconfigured via software for higher frequencies.
Does the MSP430G2101IPW14 include an analog comparator?
No, the MSP430G2101IPW14 does not include the Comparator_A+ module. That feature is exclusive to the MSP430G2x11 series (e.g., MSP430G2211IPW14). The MSP430G2101IPW14 belongs to the MSP430G2x01 series, which omits the analog comparator while retaining identical flash size, RAM, Timer_A configuration, and low-power characteristics. This distinction is clearly documented in Table 1 of the SLAS695I datasheet under "Comp_A+ Channel" column.
What debug interface does the MSP430G2101IPW14 support?
The MSP430G2101IPW14 supports the Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). It does not support full 4-wire JTAG. SBW provides full in-circuit debugging, flash programming, and real-time emulation with only two signals-reducing PCB routing complexity and connector count. TI's MSP-FET and LaunchPad development tools fully support this interface for the MSP430G2101IPW14.
Can the MSP430G2101IPW14 drive a 32.768 kHz crystal?
Yes, the MSP430G2101IPW14 can drive a 32.768 kHz crystal using the XIN/P2.6 and XOUT/P2.7 pins. The basic clock module includes dedicated circuitry for low-frequency crystal oscillation, and the device supports automatic gain control and load capacitance tuning per the SLAS695I datasheet. Crystal startup time is typically <1 s, and the resulting ACLK is used for real-time clock functions and LPM3/LPM4 operation.
What are the key differences between MSP430G2101IPW14 and MSP430G2001IPW14?
The MSP430G2101IPW14 has 1 kB flash and 128 B RAM, while the MSP430G2001IPW14 has only 512 B flash and 128 B RAM. Both share identical peripherals (Timer_A2, clock system, I/O structure), package (14-pin TSSOP), and low-power specifications. The flash size difference directly impacts firmware complexity-MSP430G2101IPW14 supports larger application code and bootloader implementations, whereas MSP430G2001IPW14 suits minimal state-machine or GPIO-timing tasks.
