Product details
Overview
MSP430G2213IPW28R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 28-pin TSSOP package, featuring 2 kB flash, 256 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, on-chip comparator (Comp_A+), and Universal Serial Communication Interface (USCI) supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2213IPW28R datasheet, MSP430G2213IPW28R pinout, MSP430G2213IPW28R application, or MSP430G2213IPW28R equivalent, key selection criteria include its 2 kB flash capacity, absence of integrated ADC10 (distinguishing it from G2x53 variants), 28-pin TSSOP footprint, Spy-Bi-Wire debug interface, and capacitive-touch-capable I/O pins for human-interface designs.
Technical Context
The MSP430G2213IPW28R implements a 16-bit CPU with constant generators and seven addressing modes, enabling efficient register-based execution at up to 16 MHz via its digitally controlled oscillator (DCO). Its clock system provides ACLK (from LF oscillator or 32-kHz crystal), MCLK (CPU clock), and SMCLK (peripheral clock), with ultra-fast wake-up (<1 µs) from LPM4 standby mode.
It integrates USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), Comp_A+ with eight input channels and programmable hysteresis, and two independent 16-bit Timer_A modules-TA0 and TA1-each with three capture/compare registers and multiple clock sources including ACLK, SMCLK, and external inputs.

Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 0.1 µA off-mode current with RAM retention enables years of operation on coin-cell batteries in always-on monitoring systems. |
| Integrated analog comparator (Comp_A+) | Eight selectable input channels with programmable hysteresis and output routing to timers or GPIO; replaces external comparators in threshold-detection circuits. |
| Universal Serial Communication Interface (USCI) | USCI_A0 supports UART with LIN auto-baud and IrDA, plus synchronous SPI; USCI_B0 supports SPI and I²C - dual interfaces simplify sensor hub and bus bridging. |
| Capacitive-touch I/O capability | Up to 24 pins support capacitive sensing via built-in oscillator; enables button/slider implementation without external ICs or firmware-intensive polling. |
| On-chip debug with Spy-Bi-Wire | Two-wire interface reduces PCB footprint and cost vs. standard JTAG; supports flash programming, breakpoints, and real-time variable inspection during development. |
| Five configurable low-power modes | LPM0–LPM4 allow granular power management: LPM3 retains ACLK for RTC while disabling CPU/SMCLK; LPM4 shuts down all clocks for maximum sleep efficiency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2233IPW28R | Includes 10-bit ADC10 (8-channel, 200 kSPS); same flash/RAM/timers but adds SAR ADC functionality. | Required where analog sensor signals need digitization without external ADC; unsuitable if ADC is unnecessary and BOM cost sensitivity is high. | Select MSP430G2233IPW28R when integrated ADC is needed; retain MSP430G2213IPW28R for pure comparator/timing/communication roles to minimize die size and cost. |
| MSP430G2113IPW28R | 1 kB flash, 128 B RAM, one 16-bit Timer_A (TA0 only); lacks USCI_B0 and Comp_A+ input multiplexing. | Targeted at simpler control tasks with minimal peripheral requirements; insufficient for dual-protocol communication or multi-channel analog comparison. | Choose MSP430G2113IPW28R only for cost-constrained, functionally minimal designs; MSP430G2213IPW28R provides necessary headroom for future firmware expansion and peripheral flexibility. |
Compared with MSP430G2233IPW28R, the MSP430G2213IPW28R omits ADC10 to reduce silicon area and cost while retaining identical timer, comparator, and communication capabilities; versus MSP430G2113IPW28R, it doubles flash and RAM, adds second Timer_A and USCI_B0, enabling more complex sensor fusion and dual-bus connectivity.

FAQ
Does MSP430G2213IPW28R include an integrated analog-to-digital converter (ADC)?
No, the MSP430G2213IPW28R does not include the ADC10 module. This distinguishes it from the MSP430G2x53 series (e.g., MSP430G2253) and confirms it belongs to the G2x13 variant group. Instead, it features the Comp_A+ analog comparator with eight input channels and slope A/D conversion capability, which can perform basic analog thresholding and ramp-based digitization without dedicated ADC hardware. The MSP430G2213IPW28R datasheet explicitly states ADC10 is available only on G2x53 devices.
What debug interface does MSP430G2213IPW28R support?
The MSP430G2213IPW28R supports Spy-Bi-Wire (SBW), a two-wire debug interface using pins RST/NMI/SBWTDIO (Pin 22) and TEST/SBWTCK (Pin 23). This interface enables full flash programming, real-time debugging, breakpoint setting, and memory inspection without requiring a full 4-pin JTAG header. SBW is electrically and logically compatible with TI's MSP-FET and LaunchPad development tools, and the MSP430G2213IPW28R includes on-chip emulation logic to support this protocol directly.
How many I/O pins on MSP430G2213IPW28R support capacitive touch sensing?
The MSP430G2213IPW28R supports capacitive touch sensing on up to 24 I/O pins across Ports P1, P2, and P3. This capability is implemented via integrated pin oscillators that detect capacitance changes without external components. Each touch-capable pin can be individually enabled and configured in software, allowing flexible layout of buttons, sliders, or proximity sensors. The feature is documented in the MSP430x2xx Family User's Guide (SLAU144) and confirmed in the device-specific datasheet SLAS735J for the G2x13 series.
What is the maximum operating frequency of MSP430G2213IPW28R?
The MSP430G2213IPW28R supports a maximum CPU instruction rate of 16 MHz, achieved using its internal digitally controlled oscillator (DCO) calibrated to four factory-trimmed frequencies. The DCO can be dynamically adjusted across ranges via RSEL and DCO bits, and its output stabilizes in less than 1 µs - enabling fast wake-up from low-power modes. While the core executes instructions at 16 MHz, peripheral clocks (ACLK, SMCLK) may run at lower frequencies depending on configuration, and the device remains fully functional across its 1.8 V–3.6 V supply range at this speed.
Is MSP430G2213IPW28R pin-compatible with other devices in the MSP430G2xx family?
Yes, the MSP430G2213IPW28R shares the same 28-pin TSSOP (PW28) package pinout with other G2x13 and G2x53 devices in the same package option, including MSP430G2233IPW28R, MSP430G2253IPW28R, and MSP430G2413IPW28R. Pin functions are consistent across these variants per Table 2 of SLAS735J, though peripheral availability (e.g., ADC10) differs. This allows hardware reuse across firmware variants - for example, designing a single PCB that supports both MSP430G2213IPW28R (no ADC) and MSP430G2233IPW28R (with ADC) by populating only required components.
