Product details
Overview
MSP430G2203IPW28 from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller in 28-pin TSSOP packaging, featuring 2 KB flash, 256 B RAM, two 16-bit Timer_A modules, USCI with UART/I²C/SPI support, and 24 capacitive-touch-capable I/O pins. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2203IPW28 datasheet, MSP430G2203IPW28 pinout, MSP430G2203IPW28 application, or MSP430G2203IPW28 equivalent, key selection criteria include active-mode current (230 µA at 1 MHz/2.2 V), wake-up time (<1 µs from standby), Spy-Bi-Wire debug interface, and absence of integrated ADC-distinguishing it from G2x33 variants.
Technical Context
The MSP430G2203IPW28 implements a 16-bit CPU with constant generators and a digitally controlled oscillator (DCO) calibrated to four internal frequencies up to 16 MHz. Its clock system supports multiple sources: internal DCO, 32-kHz crystal (XIN/XOUT), internal VLO, and external digital clock input.
It integrates two independent 16-bit Timer_A peripherals (each with three capture/compare registers), universal serial communication interfaces (USCI_A0 for UART/LIN/IrDA/SPI and USCI_B0 for SPI/I²C), brownout detection, and on-chip emulation via Spy-Bi-Wire-enabling low-overhead debugging without JTAG pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle time; enables efficient C code execution and deterministic real-time response. |
| Flash / RAM | 2 KB flash memory and 256 B RAM; sufficient for compact firmware in sensor interface and power management applications. |
| Supply Voltage | 1.8 V to 3.6 V operating range; supports direct connection to single-cell Li-ion, alkaline, or coin-cell batteries. |
| Active Current | 230 µA at 1 MHz and 2.2 V; enables multi-year operation in duty-cycled wireless sensor endpoints. |
| Wake-up Time | <1 µs from standby mode; critical for fast event-driven sampling in interrupt-sensitive systems. |
| Timer Resources | Two 16-bit Timer_A modules, each with three capture/compare registers; supports PWM generation, input capture, and interval timing. |
| Communication | USCI_A0 (UART/LIN/IrDA/SPI) + USCI_B0 (SPI/I²C); provides dual synchronous/asynchronous serial connectivity without external transceivers. |
Pinout & Package
Package: 28-pin TSSOP (PW28), 9.7 mm × 4.4 mm body size, surface-mount, lead-free RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, DVCC | Digital supply voltage | Primary power rail for core logic and I/O; must be decoupled near pin with 100 nF ceramic capacitor. |
| 2, P1.0/TA0CLK/ACLK/A0 | Multi-function I/O | Configurable as timer clock input, ACLK output, or general-purpose I/O; no ADC channel (G2203 lacks ADC). |
| 24, RST/NMI/SBWTDIO | Reset & debug I/O | Active-low reset input, non-maskable interrupt, and bidirectional Spy-Bi-Wire data line for programming and debug. |
| 25, TEST/SBWTCK | Debug clock input | Test mode select and Spy-Bi-Wire clock; required for firmware download and real-time debugging. |
| 26–27, XOUT/XIN | Crystal oscillator terminals | Supports 32.768 kHz watch crystal for precise low-power timing; internal load capacitance configurable via register. |
| 28, DVSS | Digital ground | Dedicated ground reference for digital circuitry; must be connected to system ground plane with low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | Standby current of 0.5 µA and off-mode RAM retention at 0.1 µA enable decade-scale battery life in sleep-dominated applications. |
| Five power-saving modes | Includes LPM0–LPM4; allows granular trade-off between wake-up latency, peripheral availability, and current draw per use case. |
| Spy-Bi-Wire interface | 2-wire debug protocol using only RST and TEST pins; eliminates need for full 4-pin JTAG header, saving PCB space and cost. |
| Capacitive-touch I/O | Up to 24 GPIO pins support capacitive touch sensing via built-in RC oscillation timing-no external components required. |
| Integrated clock system | Calibrated DCO with four factory-trimmed frequencies (1/2/4/8/12/16 MHz options) eliminates need for external crystal in many timing-critical functions. |
Applications
| Smart Sensor Node | Low-Power Remote Monitor |
|---|---|
|

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 |
|---|---|---|---|
| MSP430G2233IPW28 | Includes 10-bit 8-channel ADC; same package, flash/RAM, timers, and USCI peripherals. | Required when analog signal acquisition (e.g., thermistor, photodiode) is needed alongside capacitive touch. | Select MSP430G2233IPW28 if ADC functionality is essential; otherwise, MSP430G2203IPW28 offers lower cost and identical low-power performance without ADC overhead. |
| MSP430G2103IPW28 | 1 KB flash, 128 B RAM, no USCI_B0 (I²C/SPI slave only), no Timer_A3 registers-reduced peripheral set. | Suitable for simpler control tasks with minimal communication or timing requirements. | Choose MSP430G2103IPW28 only for cost-constrained, functionally minimal designs; MSP430G2203IPW28 provides superior peripheral headroom for future feature expansion. |
Compared with MSP430G2233IPW28, the MSP430G2203IPW28 removes ADC functionality while retaining identical power profile, timer capability, and communication interfaces-making it optimal for pure digital control and touch applications. Against MSP430G2103IPW28, it delivers double flash/RAM and full USCI dual-module support, enabling more complex firmware and robust interconnectivity.

FAQ
Does MSP430G2203IPW28 include an analog-to-digital converter (ADC)?
No, the MSP430G2203IPW28 does not integrate an ADC. It belongs to the G2x03 subfamily, which omits the 10-bit ADC present in G2x33 variants like MSP430G2233IPW28. Analog signal acquisition requires external ADC or selection of a G2x33 device. This omission reduces cost and power consumption where analog inputs are unnecessary.
What debug interface does MSP430G2203IPW28 support?
The MSP430G2203IPW28 supports Spy-Bi-Wire (SBW) debugging via pins 24 (RST/NMI/SBWTDIO) and 25 (TEST/SBWTCK). This 2-wire interface replaces full JTAG, enabling programming, breakpoints, and real-time variable inspection using TI's MSP-FET or compatible tools-without requiring additional PCB footprint.
Can MSP430G2203IPW28 drive capacitive touch buttons without external components?
Yes, the MSP430G2203IPW28 supports capacitive touch sensing on up to 24 I/O pins using its built-in RC oscillation timing method. No external capacitors or dedicated touch controller ICs are required-only firmware configuration and electrode layout per TI's CapTIvate™ methodology.
What is the maximum system clock frequency supported by MSP430G2203IPW28?
The MSP430G2203IPW28 supports a maximum MCLK frequency of 16 MHz at VCC ≥ 2.7 V and 12 MHz at VCC = 2.2 V, per the recommended operating conditions. The DCO is factory-calibrated to four frequencies (1/2/4/8 MHz) and can be tuned up to 16 MHz using software calibration routines.
Is MSP430G2203IPW28 pin-compatible with other devices in the G2xx family?
Yes, the MSP430G2203IPW28 shares identical 28-pin TSSOP (PW28) pinout with MSP430G2233IPW28, MSP430G2303IPW28, and MSP430G2333IPW28. This allows drop-in replacement where ADC is unused or can be implemented externally-simplifying design reuse and migration paths within the same package variant.
