Product details
Overview
MSP430G2001IPW14R from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller featuring 512 B flash, 128 B RAM, a 16-bit Timer_A with two capture/compare registers, and 10 I/O pins in a 14-pin TSSOP package. It operates from 1.8 V to 3.6 V and supports active-mode current of 220 µA at 1 MHz/2.2 V, five power-saving modes, and brownout detection - ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2001IPW14R datasheet, MSP430G2001IPW14R pinout, MSP430G2001IPW14R application, or MSP430G2001IPW14R equivalent, key selection criteria include its 14-pin TSSOP footprint, absence of analog comparator (distinguishing it from G2x11 variants), verified 16-MHz DCO capability at ≥3.3 V, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2001IPW14R implements a 16-bit RISC CPU with 16 general-purpose registers and constant generators for high code efficiency. Its clock system integrates a digitally controlled oscillator (DCO), internal low-frequency oscillator (VLO), and external crystal support (32 kHz) - enabling sub-1-µs wake-up from LPM4 standby mode.
It features a basic clock module with programmable MCLK, SMCLK, and ACLK outputs, a watchdog timer (WDT+) configurable as interval timer or reset source, and full Spy-Bi-Wire emulation logic for on-chip debugging - all operating within five software-selectable low-power modes optimized for extended battery life in portable applications.
Key Specifications

Pinout & Package
Package: 14-pin Plastic Small-Outline Thin (TSSOP), PW suffix, body size 5.0 mm × 4.4 mm, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DVCC) | Power supply | Primary VCC input (1.8–3.6 V); requires local 100-nF decoupling to DVSS. |
| 14 (DVSS) | Ground reference | Digital ground return; must be connected to system ground plane with low-inductance path. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2101IPW14R | 1 kB flash, same 128 B RAM, identical pinout and peripherals - no comparator, same Timer_A2 configuration. | Supports larger firmware images (e.g., added communication stack or calibration tables) without changing PCB layout. | Select when firmware size exceeds 512 B but analog comparator functionality is unnecessary. |
| MSP430G2001IRSA16 | Same core, memory, and peripherals, but in 16-pin QFN (RSA) package - adds two unused pins (NC), different thermal and mounting characteristics. | Preferred for space-constrained PCBs requiring smaller footprint or better thermal dissipation than TSSOP. | Select when board area or thermal performance outweighs TSSOP's reworkability and test accessibility. |
Compared with MSP430G2001IPW14R, the MSP430G2101IPW14R offers double flash capacity for enhanced feature sets without layout change, while the MSP430G2001IRSA16 delivers identical functionality in a smaller, thermally superior QFN package - both retain full software compatibility and Spy-Bi-Wire debug support.

FAQ
What is the maximum operating frequency of the MSP430G2001IPW14R?
The MSP430G2001IPW14R supports a maximum MCLK frequency of 16 MHz when VCC ≥ 3.3 V and duty cycle is 50% ± 10%. At lower supply voltages (e.g., 2.2 V), the maximum frequency is reduced to 6 MHz. This DCO-based clock is factory-calibrated and does not require an external crystal for basic operation - the MSP430G2001IPW14R achieves full-speed execution only within its specified voltage-frequency envelope.
Does the MSP430G2001IPW14R include an analog comparator?
No, the MSP430G2001IPW14R does not include the Comparator_A+ module. It belongs to the G2x01 series, which omits the analog comparator present in G2x11 variants (e.g., MSP430G2211). The MSP430G2001IPW14R retains Timer_A2, WDT+, basic clock system, and I/O - making it suitable for digital-only sensing or control tasks where slope A/D or analog signal comparison is not required.
What debug interface does the MSP430G2001IPW14R support?
The MSP430G2001IPW14R supports Spy-Bi-Wire (SBW), a two-wire variant of JTAG implemented via pins RST/NMI/SBWTDIO and TEST/SBWTCK. This interface enables full in-system programming, real-time debugging, and flash memory access using TI's MSP-FET or compatible debug probes - the MSP430G2001IPW14R does not support standard 4-wire JTAG.
How much flash and RAM does the MSP430G2001IPW14R have?
The MSP430G2001IPW14R contains 512 bytes of flash memory for program storage and 128 bytes of RAM for runtime variables and stack. Flash is organized in 512-byte segments and supports in-system programming via Spy-Bi-Wire; segment A (calibration data) is protected by default. This memory configuration suits lightweight firmware for sensor polling, LED control, or simple protocol handling - the MSP430G2001IPW14R is optimized for minimal-footprint applications.
What are the low-power mode current specifications for the MSP430G2001IPW14R?
In LPM4 (RAM retention, all clocks off), the MSP430G2001IPW14R draws 0.1 µA at 2.2 V and 25°C; typical LPM3 current is 0.5–1.5 µA depending on ACLK source (VLO vs. LFXT1). These values are measured excluding external current - the MSP430G2001IPW14R achieves these figures using its integrated brownout detector and DCO shutdown logic, enabling multi-year operation on coin cells in duty-cycled systems.
