Product details
Overview
MSP430G2213IPW28 from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 28-pin TSSOP packaging, 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 MSP430G2213IPW28 datasheet, MSP430G2213IPW28 pinout, MSP430G2213IPW28 application, or MSP430G2213IPW28 equivalent, key selection criteria include its 2 kB flash size, absence of ADC10 (distinguishing it from G2x53 variants), 28-pin TSSOP package with Port P3 support, ultra-low standby current (0.5 µA), and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2213IPW28 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 delivers ACLK, MCLK, and SMCLK from internal LF oscillator, DCO, or external 32-kHz crystal.
It integrates USCI_A0 (UART/SPI/IrDA/LIN) and USCI_B0 (SPI/I²C), Comp_A+ with eight selectable inputs, and two independent 16-bit Timer_A modules-TA0 and TA1-each with three capture/compare registers and multiple clock sources including TA0CLK, TA1CLK, and SMCLK.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 |
|---|---|---|---|
| MSP430G2231IPW14 | 14-pin TSSOP, 2 kB flash, 128 B RAM, one Timer_A, no USCI_B0, no Port P3 | Limited I/O count and peripheral set - suitable only for minimal footprint designs with basic UART or SPI | Select when board space is constrained and dual USCI or P3 functionality is unnecessary |
| MSP430G2253IPW28 | Same package and pinout, but includes 10-bit ADC10 (200 ksps, 8-channel), 512 B RAM | Enables direct analog sensor interfacing without external ADC - adds ~0.3 mA active current overhead | Choose when analog signal digitization is required and additional RAM supports more complex algorithms |
Compared with MSP430G2231IPW14, the MSP430G2213IPW28 offers expanded I/O (24 vs. 10 pins) and dual USCI; compared with MSP430G2253IPW28, it trades ADC10 capability for lower active current and reduced code memory footprint - ideal for comparator-based or digital-only sensing.

FAQ
Does the MSP430G2213IPW28 include an analog-to-digital converter (ADC)?
No, the MSP430G2213IPW28 does not include the ADC10 module. This is explicitly confirmed in TI's SLAS735J datasheet: "NOTE: ADC10 is available on MSP430G2x53 devices only." The MSP430G2213IPW28 retains the on-chip comparator (Comp_A+) for analog threshold detection and slope A/D conversion but lacks dedicated ADC hardware. For designs requiring digitized analog signals, consider the pin-compatible MSP430G2253IPW28.
What debug interface does the MSP430G2213IPW28 support?
The MSP430G2213IPW28 supports the Spy-Bi-Wire (SBW) interface using pins 24 (RST/NMI/SBWTDIO) and 25 (TEST/SBWTCK). This two-wire interface enables full in-system programming, real-time debugging, and flash memory access without requiring a full 4-pin JTAG header. It is compatible with TI's MSP-FET and LaunchPad development tools, and does not require external level-shifting for standard 3.3 V host connections.
Can the MSP430G2213IPW28 drive capacitive touch buttons?
Yes, the MSP430G2213IPW28 supports capacitive touch sensing on up to 24 I/O pins via integrated pin oscillators and software libraries (e.g., MSP430 CapTIvate™). Each supported pin can be configured with an internal oscillator to detect capacitance changes caused by finger proximity. No external RC components are needed - the solution relies on timing variations measured by Timer_A, making it suitable for cost-sensitive human-interface applications.
What is the maximum operating frequency of the MSP430G2213IPW28?
The MSP430G2213IPW28 supports a maximum CPU clock frequency of 16 MHz, achieved using the internal digitally controlled oscillator (DCO) calibrated across voltage and temperature. The DCO output is stabilized in less than 1 µs, enabling rapid transitions from LPM3/LPM4 into active mode. External clock sources (e.g., 32 kHz crystal on XIN/XOUT) may also feed ACLK or SMCLK, but MCLK - which drives the CPU - is derived from the DCO or selected internal/external sources per clock module configuration.
Is the MSP430G2213IPW28 pin-compatible with other devices in the G2x13 family?
Yes, all 28-pin TSSOP-packaged MSP430G2x13 devices - including MSP430G2213IPW28, MSP430G2313IPW28, MSP430G2413IPW28, and MSP430G2513IPW28 - share identical pinouts and package dimensions. Differences lie in flash size (2–16 kB), RAM (256 B), Timer_A channel count (2–16), and peripheral inclusion (e.g., USCI_B0 is present on all G2x13 variants). This allows scalable firmware reuse and PCB design flexibility across performance tiers.
