Product details
Overview
MSP430G2201IPW14R from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller with 2 KB flash, 128 B RAM, and a 16-bit Timer_A2 featuring 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 LPM4 with 0.1 µA RAM retention - optimized for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2201IPW14R datasheet, MSP430G2201IPW14R pinout, MSP430G2201IPW14R application, or MSP430G2201IPW14R equivalent, key selection criteria include its TSSOP-14 package, absence of on-chip 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 MSP430G2201IPW14R implements a 16-bit CPU with seven addressing modes and 51-instruction RISC core, executing register-to-register operations in one CPU cycle. 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 via ACLK or SMCLK-triggered interrupts.
It features a single 8-bit I/O port (P1) with full interrupt and pullup/pulldown control per pin, plus two dedicated P2 pins (XIN/XOUT) for crystal operation. The device lacks Comparator_A+ circuitry (confirmed by Table 1 and functional block diagram), distinguishing it from MSP430G2211 variants, and uses only Timer_A2 - no UART, SPI, or I²C peripherals are integrated.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2231IPW14R | Includes 10-bit SAR ADC (200 ksps) and USCI UART/SPI module; same 2 KB flash/128 B RAM and TSSOP-14 package | Required when analog sensing or serial communication is needed - adds 0.3 mA active current overhead | Select for sensor nodes needing direct ADC interfacing or host MCU communication without external peripherals |
| MSP430FR2111IPW14R | Ferroelectric RAM (FRAM) replaces flash: 1.5 KB FRAM + 512 B RAM; 16 MHz max, 1.8–3.6 V; includes 10-bit ADC and comparator | Superior write endurance (>10¹⁴ cycles) and faster write speed vs flash - suited for frequent data logging | Choose when firmware update frequency, data logging reliability, or write-speed constraints dominate design priorities |
Compared with MSP430G2201IPW14R, the MSP430G2231IPW14R adds essential analog and serial interfaces at modest power cost, while the MSP430FR2111IPW14R trades flash for FRAM to eliminate erase/write latency and enable true wear-leveling - both require PCB layout review due to identical TSSOP-14 footprint but distinct peripheral routing.

FAQ
What is the maximum operating frequency of the MSP430G2201IPW14R?
The MSP430G2201IPW14R supports a maximum system clock (MCLK) of 16 MHz when VCC is ≥3.3 V, as specified in the Recommended Operating Conditions table. At lower supply voltages (e.g., 2.2 V), the maximum frequency reduces to 6 MHz. This DCO-derived clock is factory-calibrated and does not require external components for basic operation. The MSP430G2201IPW14R achieves this performance while maintaining ultralow active-mode current of 220 µA at 1 MHz/2.2 V.
Does the MSP430G2201IPW14R include an analog-to-digital converter (ADC)?
No, the MSP430G2201IPW14R does not integrate an ADC. It belongs to the G2x01 series, which omits the analog comparator and ADC modules found in G2x11 variants (e.g., MSP430G2211). Its analog capability is limited to the basic clock system's internal oscillators and digital I/O only. For designs requiring analog signal acquisition, alternatives like MSP430G2231IPW14R (with 10-bit SAR ADC) or MSP430FR2111IPW14R (with 10-bit ADC and comparator) should be considered. The MSP430G2201IPW14R relies entirely on external analog front-ends.
What debug interface does the MSP430G2201IPW14R support?
The MSP430G2201IPW14R supports the Spy-Bi-Wire (SBW) interface using two dedicated pins: TEST/SBWTCK (pin 11) and RST/NMI/SBWTDIO (pin 10). This 2-wire protocol enables full in-system programming, debugging, and flash memory access without requiring a 4-pin JTAG header. SBW is electrically compatible with TI's MSP-FET and LaunchPad development tools. The MSP430G2201IPW14R does not support standard JTAG; attempting JTAG connections will not function.
How many I/O pins does the MSP430G2201IPW14R provide?
The MSP430G2201IPW14R provides ten usable I/O pins: eight bits on Port 1 (P1.0–P1.7) and two dedicated pins on Port 2 (XIN/P2.6 and XOUT/P2.7), both configurable as general-purpose I/O when crystal operation is disabled. All ten pins support individual direction control, interrupt enable, edge select, and pullup/pulldown resistor configuration. The MSP430G2201IPW14R does not expose additional GPIO beyond these ten, and no secondary peripheral multiplexing (e.g., UART, SPI) is available on these pins.
Is the MSP430G2201IPW14R pin-compatible with other MSP430G2xx devices in TSSOP-14?
Yes, the MSP430G2201IPW14R shares identical pinout and electrical characteristics with other TSSOP-14 MSP430G2xx devices, including MSP430G2101IPW14R, MSP430G2231IPW14R, and MSP430G2401IPW14R. Power (DVCC/DVSS), reset/debug (RST/NMI/SBWTDIO, TEST/SBWTCK), crystal (XIN/XOUT), and P1.x pins occupy identical positions. However, functional differences exist - for example, MSP430G2231IPW14R maps UART signals to P1.1/P1.2, while those pins remain general-purpose I/O on the MSP430G2201IPW14R. PCB layout is interchangeable, but firmware must match the specific peripheral set.
