Product details
Overview
MSP430G2202IRSA16R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 16-pin QFN (RSA) package, featuring 2 kB flash, 256 B RAM, one 16-bit Timer_A with three capture/compare registers, Universal Serial Interface (USI) for SPI/I²C, and support for up to 16 capacitive-touch I/O pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2202IRSA16R datasheet, MSP430G2202IRSA16R pinout, MSP430G2202IRSA16R application, or MSP430G2202IRSA16R equivalent, key selection criteria include its 2 kB flash capacity, USI-based serial communication capability, 16-pin QFN footprint, low-power LPM4 mode (0.1 µA), and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430G2202IRSA16R implements a 16-bit CPU with seven addressing modes and 51-instruction set, executing register-to-register operations in one CPU clock cycle. Its basic clock module integrates a digitally controlled oscillator (DCO), internal LF oscillator, and external crystal support (32 kHz), enabling sub-1 µs wake-up from standby mode.
It uses a single 16-bit Timer_A (Timer0_A3) with three capture/compare registers for PWM generation, input capture, and interval timing. The USI module provides hardware-level SPI and I²C protocol handling without CPU intervention, while digital I/O ports P1 and P2 support individually configurable pullup/pulldown resistors and capacitive-touch sensing via PinOsc.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generator; enables efficient code density and deterministic timing for real-time control. |
| Flash / RAM | 2 kB flash memory (512-byte segments) and 256 B RAM; supports in-system programming via Spy-Bi-Wire and on-chip emulation. |
| Supply Voltage | 1.8 V to 3.6 V operation; allows direct use with single Li-ion, two alkaline, or regulated 3.3 V supplies without level-shifting. |
| Ultra-Low Power Modes | Five software-selectable low-power modes including LPM4 (0.1 µA off-mode with RAM retention); extends battery life in intermittent-sensing applications. |
| Timer Resource | One 16-bit Timer_A (TA0) with three capture/compare registers (TA0.0–TA0.2); supports PWM output, input capture, and event counting with interrupt capability. |
| Serial Interface | Universal Serial Interface (USI) supporting master/slave SPI and I²C; reduces firmware overhead for sensor data acquisition and peripheral control. |

Pinout & Package
Package: 16-pin QFN (RSA), 3 mm × 3 mm, 0.4 mm pitch, exposed thermal pad (recommended connection to DVSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Power supply | Main digital supply (1.8–3.6 V); must be decoupled locally with 100 nF ceramic capacitor. |
| P1.0/TA0CLK/ACLK/A0 (Pin 2) | Multiplexed I/O | Configurable as timer clock input, ACLK output, or ADC channel 0; shared function requires software configuration via P1SEL/P1DIR. |
| P1.3/ADC10CLK/VREF-/VEREF-/A3 (Pin 5) | Multiplexed I/O | ADC10 clock output (MSP430G2x32 only); not functional on MSP430G2202IRSA16R - pin operates as general I/O or analog input A3 only. |
| P1.4/TA0.2/SMCLK/A4/TCK (Pin 6) | Multiplexed I/O | Timer compare output, SMCLK output, analog input A4, or JTAG test clock; TCK functionality active only during programming. |
| P1.6/TA0.1/SDO/SCL/A6/TDI/TCLK (Pin 8) | Multiplexed I/O | Timer compare output, USI SPI data out, I²C clock, analog input A6, or JTAG test data in; mode selected by P1SEL and USICTL0 settings. |
| RST/NMI/SBWTDIO (Pin 16) | Multi-function control | Reset input, non-maskable interrupt, or Spy-Bi-Wire bidirectional data line; critical for boot sequence and debug connectivity. |
| XIN/P2.6/TA0.1 (Pin 19) | Oscillator input | Crystal oscillator input or general I/O; when used as XIN, requires external 32.768 kHz crystal between Pins 12 and 19. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive-touch I/O | Up to 16 pins support capacitive-touch sensing via integrated PinOsc circuitry - eliminates need for external touch controllers in human-interface designs. |
| Low-power wake-up | Ultra-fast wake-up from LPM4 in less than 1 µs using DCO clock - enables responsive event-driven operation in energy-constrained systems. |
| Programmable security | On-chip code protection via programmable security fuse - prevents unauthorized readout of flash contents during production or field deployment. |
| Brownout detection | Integrated brownout reset circuit monitors DVCC and asserts reset if voltage drops below threshold - ensures reliable startup and avoids undefined MCU state. |
| Port resistor control | Individual P1REN/P2REN bits enable weak pullup/pulldown resistors on each I/O pin - simplifies button interfacing and bus termination without external components. |

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 |
|---|---|---|---|
| MSP430G2232IRSA16 | Includes 10-bit ADC10 (8-channel, 200 kSPS) and 256 B RAM; same 2 kB flash, package, and pinout. | Required where analog sensor signal digitization is needed on-board; adds ~1.5 mA active current during conversion. | Select MSP430G2232IRSA16 if ADC functionality is required; otherwise MSP430G2202IRSA16R offers lower cost and identical digital I/O/peripheral capability. |
| MSP430G2102IRSA16 | 1 kB flash, 128 B RAM, no USI module, same LPM modes and core architecture. | Suitable for simpler control tasks with minimal firmware footprint and no serial peripheral requirements. | Choose MSP430G2102IRSA16 only for deeply embedded logic-only functions; MSP430G2202IRSA16R adds USI and doubles RAM for buffer-intensive protocols. |
Compared with MSP430G2232IRSA16, the MSP430G2202IRSA16R omits ADC10 but retains full USI, Timer_A, and capacitive-touch capability - making it optimal for digital-sensor or actuator-focused designs. Against MSP430G2102IRSA16, it delivers double flash and RAM plus hardware SPI/I²C, justifying upgrade for protocol-rich edge nodes.

FAQ
What is the maximum operating frequency of the MSP430G2202IRSA16R?
The MSP430G2202IRSA16R supports internal DCO frequencies up to 16 MHz, calibrated at multiple points (1/8/12/16 MHz) stored in information memory segment A. Actual achievable frequency depends on supply voltage and temperature; at 3.0 V and 25°C, 16 MHz operation is fully specified per SLAS723H.
Does the MSP430G2202IRSA16R include an analog-to-digital converter (ADC)?
No, the MSP430G2202IRSA16R does not include an ADC. It belongs to the MSP430G2x02 series, which omits the ADC10 module present in the G2x32 variants. Pin functions labeled "A0–A7" on the datasheet are reserved but unconnected internally for ADC - they operate solely as digital I/O or timer/clock signals.
Which debug interface does the MSP430G2202IRSA16R support?
The MSP430G2202IRSA16R supports the 2-wire Spy-Bi-Wire (SBW) interface using RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This interface enables full-speed debugging, flash programming, and real-time register inspection using TI's MSP-FET or compatible third-party tools.
Can the MSP430G2202IRSA16R drive capacitive-touch buttons directly?
Yes, the MSP430G2202IRSA16R supports capacitive-touch sensing on up to 16 I/O pins using its integrated PinOsc (pin oscillator) peripheral. Each supported pin (P1.0–P1.7, P2.0–P2.5, P2.6–P2.7) can be individually enabled for touch detection without external components - confirmed in the device-specific functional block diagram and SLAS723H Section 1.1.
What are the power supply requirements for programming the MSP430G2202IRSA16R flash memory?
Flash programming for the MSP430G2202IRSA16R requires DVCC within 1.8 V to 3.6 V, matching its normal operating range. No external high-voltage programming supply is needed - the on-chip charge pump generates required voltages internally. Programming is performed via Spy-Bi-Wire using standard 3.3 V logic levels.
