Product details
Overview
MSP430G2210ID from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 2KB Flash, 128B RAM, a 16-bit Timer_A with two capture/compare registers, and a versatile analog comparator (Comparator_A+) with four input channels (CA2, CA5, CA6, CA7) and CAOUT output. It operates from 1.8 V to 3.6 V and supports five low-power modes, including LPM4 with 0.1 µA off-mode current. It targets battery-powered sensor monitoring and portable voltage supervision systems.
For engineers reviewing the MSP430G2210ID datasheet, MSP430G2210ID pinout, MSP430G2210ID application, or MSP430G2210ID equivalent, key selection criteria include its 8-pin D package, absence of ADC/USI (distinguishing it from MSP430G2230ID), verified comparator-based slope A/D capability, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2210ID implements a 16-bit RISC CPU with constant generators and 62.5-ns instruction cycle time at 16 MHz, paired with a digitally controlled oscillator (DCO) calibrated to ±1% across four frequencies (1/8/12/16 MHz). Its basic clock module supplies ACLK, MCLK, and SMCLK using internal VLO or external crystal options - though LFXT1 is not available per BCSCTL3 configuration requirements.
It integrates a dedicated Comparator_A+ module supporting precision analog signal comparison, battery-voltage supervision, and slope-type analog-to-digital conversion via CAOUT-triggered Timer_A capture. All four I/O pins (P1.2, P1.5, P1.6, P1.7) support interrupt-on-edge, individually configurable pullup/pulldown resistors, and dual-function roles tied to Timer_A and comparator inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power comparator-equipped microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2230ID | Includes 10-bit ADC10 and USI (SPI/I²C); lacks dedicated comparator input multiplexer flexibility; shares same 8-pin D package and core peripherals | Preferred for designs requiring analog sensor digitization with serial communication, not pure comparator-based thresholding | Select MSP430G2230ID only if ADC or USI functionality is required - it cannot substitute MSP430G2210ID's optimized comparator input routing or CAOUT-triggered timing |
| MSP430G2111ID | Same 8-pin D package and core architecture but omits Timer_A and Comparator_A+; offers only 1KB Flash and no analog peripheral beyond basic I/O | Suitable only for minimal GPIO-control tasks with no analog sensing or timing requirements | MSP430G2111ID is not a functional alternative for comparator or Timer_A use cases - verify design retains required analog and timing capabilities before substitution |
Compared with MSP430G2230ID and MSP430G2111ID, the MSP430G2210ID uniquely delivers integrated comparator input multiplexing, CAOUT output, and Timer_A capture/compare - making it the only option among the three for slope A/D, battery supervision, and comparator-triggered event timing in space-constrained 8-pin designs.

FAQ
What is the primary analog peripheral integrated into the MSP430G2210ID?
The MSP430G2210ID integrates the Comparator_A+ module - a four-channel analog comparator with inputs CA2, CA5, CA6, and CA7, plus a dedicated CAOUT output. This enables slope analog-to-digital conversion, battery voltage supervision, and external signal monitoring without requiring an ADC or external comparator IC. The MSP430G2210ID does not include ADC10 or USI, distinguishing it from the MSP430G2230ID variant.
Does the MSP430G2210ID support in-system programming, and what interface is used?
Yes, the MSP430G2210ID supports in-system programming via the Spy-Bi-Wire (SBW) interface using pins RST/NMI/SBWTDIO (Pin 6) and TEST/SBWTCK (Pin 7). No external programming voltage is required - the interface operates from the device's DVCC supply. Programming is performed using standard TI tools like MSP-FET or LaunchPad debuggers, and the MSP430G2210ID includes programmable code protection via a security fuse.
What are the key low-power modes supported by the MSP430G2210ID, and what is the lowest active current draw?
The MSP430G2210ID supports five software-selectable low-power modes: LPM0 through LPM4. Its lowest power state is LPM4 (off mode with RAM retention), drawing 0.1 µA at 2.2 V and 25°C. In active mode at 1 MHz and 2.2 V, it draws 220 µA - optimized for extended battery life in portable applications. Wake-up from standby occurs in less than 1 µs due to the fast-stabilizing DCO.
Can the MSP430G2210ID operate without an external crystal, and what clock sources are available?
Yes, the MSP430G2210ID can operate without an external crystal. It includes an internal digitally controlled oscillator (DCO) factory-calibrated to ±1% at 1/8/12/16 MHz, and an internal very-low-power low-frequency oscillator (VLO) for ACLK. The LFXT1 oscillator is not implemented - BCSCTL3 must be configured to select VLOCLK. External crystals are unsupported on this variant.
How many GPIO pins are accessible on the MSP430G2210ID, and what I/O features do they support?
The MSP430G2210ID provides four accessible GPIO pins (P1.2, P1.5, P1.6, P1.7) in its 8-pin D package. Each supports interrupt-on-edge (rising/falling), individually configurable pullup/pulldown resistors, and dual-function roles tied to Timer_A and Comparator_A+. Pins P1.0, P1.1, P1.3, P1.4, P2.6, and P2.7 are implemented internally but not bonded out - their pullup/pulldown resistors should be enabled to prevent floating inputs.
