Product details
Overview
MSP430G2211IPW14R 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, an on-chip 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 battery-powered sensor monitoring, analog signal conditioning, and low-cost embedded control.
For engineers reviewing the MSP430G2211IPW14R datasheet, MSP430G2211IPW14R pinout, MSP430G2211IPW14R application, or MSP430G2211IPW14R equivalent, this page delivers verified functional identity, validated pin-level circuit roles, confirmed low-power operating modes (LPM0–LPM4), exact flash/RAM allocation, and real-world use context for rapid selection and integration.
Technical Context
The MSP430G2211IPW14R implements a 16-bit RISC CPU with constant generators and 16 general-purpose registers, enabling single-cycle instruction execution at up to 16 MHz MCLK. Its clock system integrates a digitally controlled oscillator (DCO), internal low-frequency oscillator (VLO), and external 32-kHz crystal support via XIN/XOUT pins.
It includes a dedicated Comparator_A+ module with eight selectable inputs (CA0–CA7) and CAOUT output for slope A/D conversion or voltage supervision, alongside Spy-Bi-Wire debug interface and brownout detection. The device supports five power-saving modes with sub-µA retention current and wake-up in under 1 µs.

FAQ
What is the maximum operating frequency of the MSP430G2211IPW14R?
The MSP430G2211IPW14R supports a maximum MCLK frequency of 16 MHz at VCC ≥ 3.3 V with 50% ±10% duty cycle. At 2.7 V, max frequency is 12 MHz; at 1.8 V, it is limited to 6 MHz. This scaling ensures stable operation across battery discharge profiles while maintaining deterministic timing for Timer_A and instruction execution in the MSP430G2211IPW14R.
Does the MSP430G2211IPW14R include an analog-to-digital converter (ADC)?
No, the MSP430G2211IPW14R does not include an ADC. It features an 8-channel analog comparator (Comp_A+) optimized for slope A/D conversion, battery voltage supervision, and binary threshold detection. For true multi-bit digitization, engineers should consider the pin-compatible MSP430G2231IPW14R, which adds a 10-bit SAR ADC while retaining the same 14-pin TSSOP package and core peripherals as the MSP430G2211IPW14R.
How many I/O pins does the MSP430G2211IPW14R provide?
The MSP430G2211IPW14R provides 10 usable I/O pins: eight bits on Port 1 (P1.0–P1.7) and two bits on Port 2 (P2.6–P2.7). All pins support individually configurable direction, pullup/pulldown resistors, and interrupt-on-edge capability. Pins XIN and XOUT double as P2.6 and P2.7 when crystal oscillator is disabled - confirming full I/O flexibility within the 14-pin TSSOP footprint of the MSP430G2211IPW14R.
What debug interface does the MSP430G2211IPW14R support?
The MSP430G2211IPW14R supports Spy-Bi-Wire (SBW), a 2-wire debug interface using TEST/SBWTCK and RST/NMI/SBWTDIO pins. This eliminates the need for a full 4-wire JTAG header, reducing PCB space and BOM cost. SBW enables full in-system programming, breakpoint debugging, and register inspection - all supported natively by TI's Code Composer Studio and MSP430 Flash Emulation Tool for the MSP430G2211IPW14R.
Is the MSP430G2211IPW14R RoHS compliant and halogen-free?
Yes, the MSP430G2211IPW14R is RoHS compliant and halogen-free per TI's official product change notices and packaging documentation. The 14-pin TSSOP (PW) package uses lead-free matte tin plating and meets JEDEC J-STD-020 reflow profile requirements. Full compliance documentation, including material declarations and test reports, is accessible via Texas Instruments' Quality & Environmental section for the MSP430G2211IPW14R.
