Product details
Overview
MSP430I2030TPWR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller designed for precision energy metering and sensor signal acquisition. It integrates three 24-bit sigma-delta ADCs with differential PGA inputs, operates from 2.2 V to 3.6 V, delivers 16.384-MHz system clock via internal DCO, and supports eUSCI_A (UART/IrDA/SPI) and eUSCI_B (SPI/I²C) interfaces - enabling high-accuracy analog front-end processing in battery-powered metering applications.
For engineers reviewing the MSP430I2030TPWR datasheet, MSP430I2030TPWR pinout, MSP430I2030TPWR application, or MSP430I2030TPWR equivalent, key selection criteria include its 3-channel 24-bit SD24 ADC architecture, LPM4.5 shutdown current of 75 nA, TSSOP-28 package footprint, and support for single-phase AC/DC power monitoring with integrated voltage monitor (VMONIN) and temperature sensor.
Technical Context
The MSP430I2030TPWR implements a 16-bit RISC CPU with constant generators and hardware multiplier for efficient DSP operations in metrology firmware. Its analog subsystem centers on three independent SD24 modules, each configurable with programmable gain amplifiers and differential inputs - optimized for direct connection to shunt resistors or current transformers in energy measurement systems.
Digital peripherals include two 16-bit Timer_A modules (each with three capture/compare registers), dual eUSCI modules supporting asynchronous UART with auto-baud detection and synchronous I²C/SPI, and a flexible clock system featuring internal DCO with external resistor option and ACLK/SMCLK/MCLK routing - all managed under five low-power modes including LPM4.5 with full RAM retention.

FAQ
What is the maximum sampling rate supported by the SD24 ADCs in MSP430I2030TPWR?
The MSP430I2030TPWR SD24 modules support up to 256 kSPS aggregate throughput across all three channels. Each 24-bit sigma-delta ADC achieves effective sampling rates up to 85 kSPS at 16-bit resolution (OSR = 64) or 4.2 kSPS at full 24-bit resolution (OSR = 2048), with programmable oversampling ratios and built-in digital filters for harmonic analysis - directly enabling IEC 61000-4-7 compliance testing.
Does MSP430I2030TPWR require an external crystal oscillator?
No, the MSP430I2030TPWR operates from its internal 16.384-MHz digitally controlled oscillator (DCO) with ±1% typical accuracy over voltage and temperature. An external crystal is optional and only needed if tighter timing stability (<±100 ppm) is required for time-of-use billing or synchronization with grid events - the DCO suffices for most Class 0.5S metering applications.
How many GPIO pins are available on MSP430I2030TPWR in the TSSOP-28 package?
The MSP430I2030TPWR in TSSOP-28 provides 16 usable GPIO pins: P1.0–P1.7 (8 pins) and P2.0–P2.3 plus P2.4–P2.7 (8 pins), though P2.4–P2.7 are not physically present in the 28-pin variant and must be software-configured as outputs driven low. All 16 pins support interrupt capability and peripheral multiplexing per device configuration.
Can MSP430I2030TPWR perform real-time harmonic analysis?
Yes, the MSP430I2030TPWR supports real-time harmonic analysis through its hardware multiplier and optimized instruction set. With three synchronized SD24 ADCs capturing voltage and current waveforms, firmware can execute Goertzel or FFT-based algorithms on 1–50th harmonics using the 16×16 hardware multiplier - achieving <1% THD error at 50/60 Hz with 16-bit effective resolution and on-chip temperature compensation.
What development tools are officially supported for MSP430I2030TPWR?
Texas Instruments officially supports the MSP430I2030TPWR with the EVM430-I2040S evaluation module (EVM) for metering, MSP-TS430RHB32A target board, Code Composer Studio™ IDE, MSP430Ware™ code examples, and the Energy Measurement Design Center - all providing calibrated reference designs, metrology firmware libraries, and IEC 62053-compliant test vectors for rapid validation.
