Texas Instruments MSP430G2201IPW14

Overview

MSP430G2201IPW14 from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 2 KB flash, 128 B RAM, a 16-bit Timer_A with two capture/compare registers, and 10 general-purpose 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, enabling battery-powered sensor node applications requiring sub-µA standby current and fast wake-up.

For engineers reviewing the MSP430G2201IPW14 datasheet, MSP430G2201IPW14 pinout, MSP430G2201IPW14 application, or MSP430G2201IPW14 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases for low-cost embedded sensing, and confirmed alternative options aligned with TI's G2x01 family specifications.

Technical Context

The MSP430G2201IPW14 implements a 16-bit RISC CPU with constant generators and 16 general-purpose registers, executing instructions in one CPU clock cycle at up to 16 MHz (DCO-derived). Its clock system integrates a digitally controlled oscillator (DCO), internal very-low-power LF oscillator, and external 32-kHz crystal support - all configurable via BCSCTL registers.

It includes a brownout detector, watchdog timer (WDT+), Spy-Bi-Wire emulation interface, and basic digital I/O on Port P1 (8 bits) and Port P2 (2 bits), with individually programmable pullup/pulldown resistors and edge-selectable interrupts. No analog comparator is present - distinguishing it from the MSP430G2x11 series.

FAQ

What is the maximum operating frequency of the MSP430G2201IPW14?

The MSP430G2201IPW14 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 drops to 6 MHz. These limits are enforced by the internal DCO and basic clock module, and all timing-critical peripherals (e.g., Timer_A, UART) derive from MCLK or its derivatives (SMCLK, ACLK).

Does the MSP430G2201IPW14 include an analog comparator or ADC?

No, the MSP430G2201IPW14 does not include an analog comparator or ADC. It belongs to the G2x01 series, which omits the Comparator_A+ module found in the G2x11 variants (e.g., MSP430G2211IPW14). For analog sensing, external signal conditioning or a variant with integrated ADC (e.g., MSP430G2231IPW14) is required.

What debug interface does the MSP430G2201IPW14 support?

The MSP430G2201IPW14 supports Spy-Bi-Wire (SBW), a 2-wire debug interface using pins RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). It replaces full 4-wire JTAG and is fully compatible with TI's MSP-FET and LaunchPad development tools for programming and real-time debugging.

Can the MSP430G2201IPW14 operate from a 1.8 V supply?

Yes, the MSP430G2201IPW14 is fully specified to operate from 1.8 V to 3.6 V. At 1.8 V, it supports up to 6 MHz MCLK, consumes 220 µA in active mode (1 MHz), and maintains full functionality including flash programming (with minimum 2.2 V required only during erase/write cycles).

What are the key differences between MSP430G2201IPW14 and MSP430G2211IPW14?

The MSP430G2201IPW14 and MSP430G2211IPW14 share identical flash (2 KB), RAM (128 B), package (14-pin TSSOP), and core peripherals. The key difference is that MSP430G2211IPW14 includes the Comparator_A+ module with 8-channel analog inputs and CAOUT, while MSP430G2201IPW14 has no analog comparator - confirmed in Table 1 and functional block diagrams.
