Product details
Overview
MSP430I2030TRHBR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller optimized for precision energy metering and battery-powered monitoring applications. It integrates three 24-bit sigma-delta ADCs with differential PGA inputs, operates across 2.2 V–3.6 V, delivers 16.384-MHz system clock performance, and achieves 70 µA shutdown current (LPM4) and 75 nA LPM4.5 mode - enabling multi-year operation on coin-cell batteries in smart plugs and submeters.
For engineers reviewing the MSP430I2030TRHBR datasheet, MSP430I2030TRHBR pinout, MSP430I2030TRHBR application, or MSP430I2030TRHBR equivalent, this page provides verified technical context, validated RHB-package pin functions, confirmed metrology-grade analog specs, and two field-tested alternative MCUs for single-phase power monitoring designs.
Technical Context
The MSP430I2030TRHBR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO) that wakes from LPM4 in ≤1 µs. Its analog subsystem centers on three independent 24-bit sigma-delta ADCs, each with programmable gain amplifiers and differential input pairs - supporting simultaneous voltage/current/neutral sensing in Class 0.5 energy meters.
Digital peripherals include two 16-bit Timer_A modules (each with three capture/compare registers), dual eUSCI interfaces (eUSCI_A0 supporting UART/IrDA/SPI; eUSCI_B0 supporting SPI/I²C), and a hardware multiplier for real-time DSP operations. Power management integrates an on-chip LDO delivering 1.8-V core supply, brownout detection, and temperature sensor - all configurable without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar metrology microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430I2031TRHBR | 32 KB Flash / 2 KB RAM vs. 16 KB Flash / 1 KB RAM; identical ADC count, package, and peripheral set. | Required when firmware exceeds 16 KB or requires larger data buffers for harmonic analysis. | Select MSP430I2031TRHBR if future firmware expansion or advanced waveform processing is anticipated. |
| MSP430I2040TRHBR | Four 24-bit SD24 ADCs (vs. three); same Flash/RAM, package, and low-power specs. | Suitable for 3-phase metering or applications requiring redundant sensing channels. | Choose MSP430I2040TRHBR only if fourth ADC channel is required - adds no benefit for single-phase designs. |
Compared with MSP430I2031TRHBR and MSP430I2040TRHBR, the MSP430I2030TRHBR delivers optimal cost-performance balance for certified single-phase metering, offering full metrology capability in the smallest memory footprint and lowest unit cost within the RHB-packaged i203x family.

FAQ
What is the maximum ADC sampling rate supported by the MSP430I2030TRHBR?
The MSP430I2030TRHBR's three 24-bit sigma-delta ADCs support up to 256 kSPS aggregate throughput when oversampling ratio (OSR) is reduced. At OSR = 256 - typical for metrology - effective sampling rate per channel is 1 kSPS, enabling precise RMS and fundamental frequency calculation per IEC 62053 standards. The MSP430I2030TRHBR maintains this performance across its full 2.2–3.6 V supply range.
Does the MSP430I2030TRHBR support hardware-based cryptographic acceleration?
No, the MSP430I2030TRHBR does not include dedicated cryptographic accelerators or secure key storage. It relies on software-based AES-128 implementation for basic firmware authentication. For designs requiring FIPS 140-2 or IEC 62443 compliance, external secure elements or higher-tier MSP430FRxx FRAM devices with integrated AES modules are recommended instead of the MSP430I2030TRHBR.
Can the MSP430I2030TRHBR operate from a 1.8-V supply?
No, the MSP430I2030TRHBR requires a minimum supply voltage of 2.2 V per its absolute maximum ratings and recommended operating conditions. Operation below 2.2 V may cause ADC inaccuracies, flash corruption, or failure to exit LPM4.5. The internal LDO regulates core voltage to 1.8 V, but VCC must remain ≥2.2 V - the MSP430I2030TRHBR is not rated for direct 1.8-V rail operation.
How many GPIO pins are available on the MSP430I2030TRHBR in the RHB package?
The MSP430I2030TRHBR in the 32-pin VQFN (RHB) package provides 16 GPIO pins: P1.0–P1.7 and P2.0–P2.7. All support interrupt capability and peripheral multiplexing (eUSCI, Timer_A, SD24 control). Pins P2.4–P2.7 are exclusive to the RHB package and unavailable in the 28-pin TSSOP variant - confirming full I/O access for complex metering I/O routing in the MSP430I2030TRHBR.
Is the MSP430I2030TRHBR qualified for automotive applications?
No, the MSP430I2030TRHBR is not AEC-Q100 qualified and is specified only for industrial and commercial temperature ranges (–40°C to 85°C). While it meets the temperature range, it lacks automotive-specific qualification testing (e.g., HTOL, ESD, EMC). For automotive body electronics or charging infrastructure, TI's MSP430FR69xx or C2000™ Delfino™ families with AEC-Q100 certification should be used instead of the MSP430I2030TRHBR.
