Product details
Overview
MSP430G2230IDR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2 KB Flash, 128 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, and a Universal Serial Interface (USI) supporting SPI and I²C protocols. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430G2230IDR datasheet, MSP430G2230IDR pinout, MSP430G2230IDR application, or MSP430G2230IDR equivalent, key selection criteria include its 8-pin SOIC-D package, four GPIO pins with interrupt capability, LPM4 standby current of 0.1 µA, integrated DCO with ±1% calibration at 16 MHz, and USI-based serial interface without external transceivers.
Technical Context
The MSP430G2230IDR implements a 16-bit RISC CPU with constant generators and six software-selectable low-power modes, enabling sub-1-µs wake-up from LPM4 via port interrupts or timer events. Its basic clock system integrates a digitally controlled oscillator (DCO), internal VLO, and ACLK/SMCLK/MCLK domains - all configurable without external crystals.
Peripherals are memory-mapped and accessible via standard instructions: the USI module handles synchronous serial communication using shared P1 pins for SCLK/SDO/SDI/SDA, while the ADC10 supports four analog inputs (A2–A7), internal reference, sample-and-hold, and DMA-triggered autoscan - all operating independently of CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430G2210IDR | Lacks ADC10 and USI; includes Comparator_A+ instead; same Flash/RAM/package | Battery supervision and slope ADC only - no serial comms or multi-channel conversion | Select when analog comparator functionality suffices and serial interface is unnecessary |
| MSP430G2231IPW | Same core/peripherals but in 20-pin TSSOP; adds two extra GPIOs and VREF+ pin | Higher I/O count and dedicated reference enable more complex analog front-ends | Choose when additional pins or external reference stability are required |
Compared with MSP430G2230IDR, MSP430G2210IDR omits critical serial and ADC capabilities for cost-sensitive comparator-only use cases, while MSP430G2231IPW trades compact 8-pin packaging for expanded I/O and reference flexibility - making MSP430G2230IDR optimal for space-constrained, self-contained sensor nodes requiring both analog acquisition and embedded communication.

FAQ
What is the maximum operating frequency of the MSP430G2230IDR?
The MSP430G2230IDR supports a maximum MCLK frequency of 16 MHz at VCC ≥ 3.3 V, with factory-calibrated DCO settings at 1/8/12/16 MHz achieving ±1% accuracy. At 2.7 V, max frequency is 12 MHz; at 1.8 V, it is limited to 6 MHz. These values are specified under 50% duty cycle and apply to CPU and peripheral clock domains.
Does the MSP430G2230IDR support hardware I²C communication?
Yes, the MSP430G2230IDR supports hardware I²C through its Universal Serial Interface (USI) module. Pins P1.5 (SCLK), P1.6 (SCL), and P1.7 (SDA) are configured for I²C operation, enabling standard-mode (100 kHz) and fast-mode (400 kHz) communication without CPU intervention or bit-banging.
How many analog input channels does the ADC10 module support on the MSP430G2230IDR?
The ADC10 module on the MSP430G2230IDR supports four analog input channels: A2, A5, A6, and A7 - mapped to pins P1.2, P1.5, P1.6, and P1.7 respectively. The module provides internal 1.5-V reference, sample-and-hold, and autoscan mode for sequential conversion across all enabled channels.
What debug interface does the MSP430G2230IDR use?
The MSP430G2230IDR uses the Spy-Bi-Wire (SBW) interface for debugging and programming, requiring only two pins: SBWTDIO (Pin 6) and SBWTCK (Pin 7). This 2-wire JTAG variant enables full flash programming, breakpoint setting, and real-time variable inspection using TI's MSP-FET or compatible tools.
Is the MSP430G2230IDR pin-compatible with other devices in the MSP430G22x0 family?
Yes, the MSP430G2230IDR shares the identical 8-pin SOIC (D) package and pinout with MSP430G2210IDR and MSP430G2220IDR. However, peripheral availability differs: only MSP430G2230IDR includes ADC10 and USI; others offer comparator or different timer configurations - firmware and schematic must be validated per variant.
