Texas Instruments MSP430I2030TPW

Overview

MSP430I2030TPW from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller optimized for precision energy metering and sensor monitoring. 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 - all in a 28-pin TSSOP package for compact metering modules.

For engineers reviewing the MSP430I2030TPW datasheet, MSP430I2030TPW pinout, MSP430I2030TPW application, or MSP430I2030TPW equivalent, key selection criteria include its 3-channel 24-bit SD24 ADC architecture, LPM4.5 shutdown current of 75 nA, integrated LDO core regulator, and support for single-phase AC/DC power monitoring in space-constrained designs.

Technical Context

The MSP430I2030TPW implements a 16-bit RISC CPU with constant generators and five low-power modes (LPM0–LPM4.5), enabling sub-µs wake-up from standby (1 µs) and ultra-low active-mode consumption (275 µA/MHz at 16.384 MHz). Its analog subsystem centers on three independent SD24 modules, each supporting programmable gain amplifiers and differential input pairs for high-resolution metrology-grade signal acquisition.

Digital peripherals include two 16-bit Timer_A modules (each with three capture/compare registers), a hardware multiplier for 16×16 operations, and dual eUSCI modules - one configured for enhanced UART with auto-baud detection and IrDA, the other for synchronous SPI or I²C - all managed by a flexible power management system featuring supply voltage monitoring, brownout detection, and an internal temperature sensor.

FAQ

What is the maximum ADC sampling rate supported by the MSP430I2030TPW?

The MSP430I2030TPW supports up to 256 kSPS aggregate throughput across its three 24-bit sigma-delta ADCs when oversampling ratio (OSR) is set to minimum (e.g., OSR = 64). Individual channel effective sampling rate depends on resolution and OSR configuration - for 24-bit precision, typical sustained rate is 1–4 kSPS per channel with digital filtering enabled. This is confirmed in Section 8.7.7 of the SLAS887C datasheet.

Does the MSP430I2030TPW support hardware-based AES encryption?

No, the MSP430I2030TPW does not include a hardware AES accelerator or cryptographic module. It relies on software-based implementations for security functions. The device lacks dedicated crypto peripherals; its security features are limited to JTAG lock, flash segment protection, and basic password-protected debug access - as documented in Section 9.9 (JTAG Operation) and Section 9.8 (Flash Memory) of the SLAS887C datasheet.

Can the MSP430I2030TPW operate from a 1.8-V supply?

No, the MSP430I2030TPW requires a minimum supply voltage of 2.2 V and supports up to 3.6 V per Section 8.3 (Recommended Operating Conditions) in SLAS887C. Operation below 2.2 V violates absolute ratings and may cause unstable ADC performance, SRAM retention loss, or core reset behavior. The integrated LDO generates 1.8-V VCORE internally but does not accept 1.8-V VCC input.

How many GPIO pins are available on the MSP430I2030TPW in the 28-pin TSSOP package?

The MSP430I2030TPW provides 16 GPIO pins in the 28-pin TSSOP (PW) package: P1.0 through P1.7 (8 pins) and P2.0 through P2.3 (4 pins), plus four additional pins (P2.4–P2.7) that are not bonded out in the PW variant and must be configured as outputs driven low in software per Section 7.2 footnote (8) of SLAS887C.

Is the MSP430I2030TPW pin-compatible with the MSP430I2040TPW?

Yes, the MSP430I2030TPW is pin-compatible with the MSP430I2040TPW in the 28-pin TSSOP package. Both share identical pin assignments, power domains, and peripheral mappings per Figures 7-2 and 7-4 of SLAS887C. The only difference is ADC count (three vs. four), with A3.0± pins unused (NC) and recommended to be tied to AVSS in MSP430I2030TPW designs.
