Product details
Overview
MSP430G2210IDR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 2KB Flash, 128B RAM, and a versatile analog comparator (COMP_A+) supporting slope ADC, battery monitoring, and external signal comparison. It operates from 1.8 V to 3.6 V, achieves 220 µA active current at 1 MHz/2.2 V, and features four GPIO pins (P1.2, P1.5, P1.6, P1.7), Timer_A2 with two capture/compare registers, and brownout protection - deployed in compact battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2210IDR datasheet, MSP430G2210IDR pinout, MSP430G2210IDR application, or MSP430G2210IDR equivalent, this page delivers verified functional identity, validated 8-pin SOIC (D) package mapping, confirmed comparator-centric peripheral set, exact low-power mode behavior (LPM4 = 0.1 µA), and two technically documented alternative parts for design continuity.
Technical Context
The MSP430G2210IDR implements a 16-bit RISC CPU with constant generators and six software-selectable operating modes (AM, LPM0–LPM4), enabling sub-1 µs wake-up from standby. Its basic clock system integrates a digitally controlled oscillator (DCO) calibrated at 1/8/12/16 MHz, internal VLO, and ACLK/SMCLK/MCLK distribution - all without external crystals.
Unlike the MSP430G2230IDR, the MSP430G2210IDR omits ADC10 and USI modules but includes COMP_A+ with four selectable inputs (CA2, CA5, CA6, CA7), CAOUT output, and interrupt flag CAIFG. All four I/O pins support individually configurable pullup/pulldown resistors, edge-selectable interrupts, and dual-function roles with Timer_A2 and comparator signals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power comparator-based microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2230IDR | Includes ADC10 (10-bit, 200 ksps) and USI (SPI/I²C), but lacks COMP_A+ interrupt flag CAIFG and comparator output CAOUT. | Required where analog signal digitization or serial communication is needed; unsuitable for pure comparator-triggered wake-up without firmware polling. | Select MSP430G2230IDR only if ADC or USI functionality is mandatory; MSP430G2210IDR remains superior for comparator-first use cases. |
| MSP430FR2110IRSWR | Ferroelectric RAM (FRAM) instead of Flash; same 2KB program memory, 128B RAM, and integrated comparator; adds 16-bit timer and enhanced LPM3.5/LPM4.5 modes. | Offers faster write endurance and lower write energy than Flash; supports deeper sleep states for intermittent harvesting applications. | Prefer MSP430FR2110IRSWR for designs requiring frequent parameter updates or sub-50 nA deep-sleep operation; MSP430G2210IDR suits cost-sensitive, static-firmware deployments. |
Compared with MSP430G2230IDR, the MSP430G2210IDR delivers dedicated comparator interrupt capability and lower system-level component count for threshold-detection tasks; versus MSP430FR2110IRSWR, it trades FRAM endurance and ultra-deep sleep for lower unit cost and proven Flash reliability in fixed-function embedded roles.

FAQ
What is the primary differentiating feature of the MSP430G2210IDR compared to other MSP430G2xx variants?
The MSP430G2210IDR is uniquely defined by its integrated COMP_A+ analog comparator with dedicated interrupt flag (CAIFG) and output pin (CAOUT), enabling hardware-triggered wake-up and threshold detection without CPU intervention. Unlike the MSP430G2230IDR, it excludes ADC10 and USI modules - making it the optimal choice for comparator-centric, low-component-count designs where analog-to-digital conversion or serial communication is unnecessary. This specialization reduces both BOM cost and firmware complexity in applications like battery supervision and simple sensor triggers.
Does the MSP430G2210IDR support in-system programming, and what interface is required?
Yes, the MSP430G2210IDR supports full in-system programming and debugging via the Spy-Bi-Wire (SBW) interface, which uses only two pins: RST/NMI/SBWTDIO (pin 6) and TEST/SBWTCK (pin 7). No external programming voltage is needed - the device operates from its standard 1.8–3.6 V supply. The SBW interface is compatible with TI's MSP-FET and LaunchPad development tools, and allows complete Flash memory erase, program, and verify operations without removing the MSP430G2210IDR from the target board.
What are the exact low-power mode current specifications for the MSP430G2210IDR at 2.2 V?
At 2.2 V supply and 25°C, the MSP430G2210IDR draws 0.5 µA in LPM3 (VLO active), 0.1 µA in LPM4 (all clocks off, RAM retained), and 65 µA in LPM0 (SMCLK active, CPU off). These values are measured with brownout enabled and all unused I/Os configured as outputs or with pullup/pulldown resistors enabled. The 0.1 µA LPM4 current enables decade-scale operation on small batteries - critical for maintenance-free IoT endpoints where battery replacement is impractical.
Can the MSP430G2210IDR generate precise timing signals without an external crystal?
Yes, the MSP430G2210IDR includes a factory-calibrated digitally controlled oscillator (DCO) with four trim points (1/8/12/16 MHz) accurate to ±1% over temperature and voltage. This allows reliable generation of MCLK, SMCLK, and ACLK without external crystals or resonators. For example, UART baud rates can be derived directly from the 1 MHz DCO setting, and Timer_A2 can produce stable PWM waveforms using SMCLK - eliminating BOM cost and board space associated with external timing components.
How many GPIO pins are accessible on the MSP430G2210IDR, and what I/O capabilities do they support?
The MSP430G2210IDR provides four fully functional GPIO pins: P1.2, P1.5, P1.6, and P1.7. Each supports individual direction control (input/output), programmable pullup/pulldown resistors, edge-selectable interrupts (rising/falling), and multiple peripheral functions - including Timer_A2 capture/compare signals and COMP_A+ inputs/outputs. While additional GPIOs (P1.0, P1.1, etc.) exist internally, they are not bonded out on the 8-pin D package and must be disabled or configured as inputs with pullups to prevent floating states.
