Product details
Overview
MSP430G2230QDREP from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with 2 kB Flash, 128 B RAM, and integrated peripherals including a 10-bit 200-ksps ADC, Timer_A2 with two capture/compare registers, Universal Serial Interface (USI) for SPI/I²C, and brownout detection. It operates from 1.8 V to 3.6 V and targets battery-powered portable measurement systems requiring long runtime and rapid wake-up.
For engineers reviewing the MSP430G2230QDREP datasheet, MSP430G2230QDREP pinout, MSP430G2230QDREP application, or MSP430G2230QDREP equivalent, this page delivers verified technical context, exact pin functions, low-power mode timing, calibrated DCO frequencies (1/8/12/16 MHz), and validated alternatives for radiation-tolerant embedded control in defense, aerospace, and medical environments.
Technical Context
The MSP430G2230QDREP implements a 16-bit RISC CPU with six general-purpose registers, constant generators, and register-to-register execution in one MCLK cycle. Its basic clock module integrates a digitally controlled oscillator (DCO) factory-calibrated at 1, 8, 12, and 16 MHz ±1%, plus internal VLO and external 32-kHz crystal support (limited to ≤105°C).
Five software-selectable low-power modes (LPM0–LPM4) enable sub-µA standby (0.5 µA) and off-mode (0.1 µA RAM retention) operation. Wake-up from LPM3/LPM4 to active mode occurs in under 1 µs via interrupt on any of four P1 I/O pins - all with individually configurable pullup/pulldown resistors, edge-selectable interrupts, and Schmitt-trigger inputs.

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 |
|---|---|---|---|
| MSP430G2212QDREP | Same 8-pin D package and core architecture, but only 2 kB Flash, no ADC, and no USI - lacks analog and serial peripherals. | Suitable for pure digital control tasks without sensing or host communication; not viable for ADC- or I²C-dependent designs. | Select only if application requires minimal code footprint and omits analog acquisition or serial interfacing. |
| MSP430FR2111IPWTR | Ferroelectric RAM (FRAM) replaces Flash; 1.5 kB FRAM + 512 B RAM; same USI and 10-bit ADC; operates –40°C to 85°C (not 125°C). | Offers faster write endurance and lower active power, but lacks extended temperature rating and defense-grade traceability. | Prefer for commercial industrial IoT where FRAM benefits outweigh military-spec requirements and extended temp range. |
Compared with MSP430G2230QDREP, MSP430G2212QDREP removes critical analog/serial capability for cost reduction, while MSP430FR2111IPWTR trades radiation tolerance and 125°C operation for FRAM advantages - neither is pin-compatible nor drop-in; both require PCB and firmware adaptation.
