Product details
Overview
MSP430G2233IPW28R from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 2 KB flash, 256 B RAM, 10-bit 200-ksps ADC (8-channel), two 16-bit Timer_A modules, USCI with UART/LIN/IrDA/SPI/I²C, and capacitive-touch-capable I/O - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430G2233IPW28R datasheet, MSP430G2233IPW28R pinout, MSP430G2233IPW28R application, or MSP430G2233IPW28R equivalent, key selection criteria include active-mode current at 1 MHz (230 µA @ 2.2 V), standby current (0.5 µA), ADC resolution and sampling rate, TSSOP-28 package compatibility, and Spy-Bi-Wire debug interface support.
Technical Context
The MSP430G2233IPW28R implements a 16-bit CPU with constant generators and a digitally controlled oscillator (DCO) enabling sub-1-µs wake-up from LPM3/LPM4. Its clock system integrates internal calibrated DCO (up to 16 MHz), 32-kHz crystal support (XT1), and VLO for ultra-low-power timing.
Peripherals include dual 16-bit Timer_A units (each with three capture/compare registers), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and an ADC10 with internal reference, sample-and-hold, autoscan, and temperature sensor - all operating within 1.8–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables efficient C code execution and deterministic real-time response. |
| Flash / RAM | 2 KB flash memory (in-system programmable, no external VPP); 256 B RAM - sufficient for compact firmware with sensor data buffering. |
| ADC Performance | 10-bit, 200-ksps SAR ADC with 8 input channels, internal reference, autoscan, and integrated temperature sensor - supports multi-sensor analog acquisition without external components. |
| Power Consumption | Active mode: 230 µA @ 1 MHz / 2.2 V; Standby: 0.5 µA; Off mode (RAM retention): 0.1 µA - extends coin-cell battery life to years in intermittent-sensing applications. |
| Timers & Communication | Two 16-bit Timer_A (3 CC registers each); USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C) - enables dual-protocol connectivity and precise PWM/timing control. |
| Operating Voltage | 1.8 V to 3.6 V supply range - compatible with single-cell Li-ion, LiFePO₄, or dual-AA alkaline systems without regulators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2333IPW28R | 4 KB flash, 256 B RAM, identical peripherals and pinout - higher code capacity without layout change. | Suitable for firmware requiring larger bootloader, protocol stacks, or extended feature sets. | Select when additional flash space is needed for future firmware updates or enhanced functionality. |
| MSP430G2213IPW28R | No ADC10 module; otherwise identical core, timers, USCI, and power specs - reduced analog capability. | Targeted at digital-only control tasks (e.g., LED drivers, logic sequencers) where analog sensing is unnecessary. | Choose for cost-optimized digital control applications where ADC is omitted to reduce silicon cost. |
Compared with MSP430G2233IPW28R, the G2333 offers more flash for complex firmware while maintaining pin and peripheral compatibility, whereas the G2213 removes the ADC to lower cost for purely digital functions - enabling scalable design across performance tiers.

FAQ
What is the maximum system clock frequency supported by the MSP430G2233IPW28R?
The MSP430G2233IPW28R supports up to 16 MHz MCLK when VCC ≥ 3.3 V, 12 MHz at 2.7 V, and 6 MHz at 1.8 V - with DCO calibration enabling stable operation across voltage and temperature without external crystal for many applications. The MSP430G2233IPW28R's internal DCO eliminates need for high-frequency external oscillators in timing-flexible designs.
Does the MSP430G2233IPW28R include hardware support for capacitive touch sensing?
Yes, the MSP430G2233IPW28R supports capacitive touch on up to 24 I/O pins using its built-in RC oscillator and timer-based measurement - no external components required. This capability is implemented in firmware using the MSP430G2233IPW28R's Timer_A modules and GPIO configuration, enabling robust touch button and slider implementations.
Can the MSP430G2233IPW28R operate from a single 1.8 V supply?
Yes, the MSP430G2233IPW28R is fully specified for operation from 1.8 V to 3.6 V, including flash programming (minimum 2.2 V) and active-mode execution. At 1.8 V, it delivers 6 MHz system frequency and maintains full peripheral functionality - making the MSP430G2233IPW28R ideal for single-cell lithium primary or rechargeable systems.
What debug interface does the MSP430G2233IPW28R use, and how many pins are required?
The MSP430G2233IPW28R uses Spy-Bi-Wire (SBW), a 2-pin debug interface (SBWTDIO and SBWTCK) compatible with TI's MSP-FET and LaunchPad tools. This replaces full 4-wire JTAG, reducing PCB routing complexity and connector size while retaining full flash programming, breakpoint, and register inspection capabilities for the MSP430G2233IPW28R.
Is the ADC on the MSP430G2233IPW28R capable of autonomous operation without CPU intervention?
Yes, the MSP430G2233IPW28R's ADC10 supports autoscan mode with DMA trigger capability - allowing continuous conversion across up to 8 channels while the CPU remains in low-power mode. This autonomous acquisition is configured via ADC10CTL1 register settings and enables efficient multi-sensor polling without CPU overhead in the MSP430G2233IPW28R.
