Product details
Overview
MSP430G2744IRHA40T from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 32KB flash, 1KB RAM, 10-bit 200-ksps ADC, dual 16-bit timers (Timer_A3 and Timer_B3), USCI supporting UART/LIN/IrDA/SPI/I²C, and integrated DCO clocking up to 16 MHz - deployed in battery-powered sensor nodes and RF front ends requiring sub-1µs wake-up and <0.1 µA off-mode retention.
For engineers reviewing the MSP430G2744IRHA40T datasheet, MSP430G2744IRHA40T pinout, MSP430G2744IRHA40T application, or MSP430G2744IRHA40T equivalent, key selection criteria include calibrated DCO frequency stability across voltage/temperature, ADC10 autoscan + DTC for autonomous analog acquisition, Spy-Bi-Wire debug interface compatibility, and QFN-40 (RHA) package thermal performance in space-constrained designs.
Technical Context
The MSP430G2744IRHA40T implements a 16-bit CPU with constant generators and five low-power modes (LPM0–LPM4), enabling extended battery life in portable measurement systems. Its basic clock system integrates DCO (calibrated at 1/8/12/16 MHz), LFXT1 (32-kHz crystal), VLO, and external clock sources - all selectable via BCSCTL registers.
Peripherals are synchronized to MCLK, SMCLK, or ACLK domains: USCI_A0 supports enhanced UART with automatic baud-rate detection (LIN), IrDA encoding/decoding, and SPI master/slave; USCI_B0 handles SPI and I²C; ADC10 includes internal reference, sample-and-hold, and data transfer controller for DMA-like operation without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430G2744IRHA40T?
The MSP430G2744IRHA40T supports a maximum system clock (MCLK) frequency of 16 MHz when VCC ≥ 3.3 V and duty cycle is 50% ±10%. This is achieved using the factory-calibrated DCO. The actual achievable frequency depends on supply voltage: 4.15 MHz at 1.8 V, 12 MHz at 2.7 V, and 16 MHz at 3.3–3.6 V. All timing specifications in the datasheet assume this MCLK constraint.
Does the MSP430G2744IRHA40T support hardware UART with automatic baud-rate detection?
Yes, the MSP430G2744IRHA40T's USCI_A0 module implements enhanced UART mode with automatic baud-rate detection compliant with LIN 2.x standards. This feature allows the MSP430G2744IRHA40T to synchronize to incoming bus traffic without prior knowledge of bit rate - critical for automotive diagnostic interfaces and interoperable sensor networks.
How many analog input channels does the ADC10 module support on the MSP430G2744IRHA40T?
The ADC10 module on the MSP430G2744IRHA40T supports 12 analog input channels (A0–A7, A12–A15), accessible through dedicated pins including P2.0/A0, P2.1/A1, P2.2/A2, P2.3/A3, P2.4/A4, P3.6/A6, P3.7/A7, P4.3/A12, P4.4/A13, P4.5/A14, and P4.6/A15. Channel selection is fully configurable in software via ADC10CTL1 register.
What debug interface does the MSP430G2744IRHA40T use, and what pins are required?
The MSP430G2744IRHA40T uses the Spy-Bi-Wire (SBW) interface - a two-wire variant of JTAG - requiring only TEST/SBWTCK (pin 1) and RST/NMI/SBWTDIO (pin 6) on the RHA package. This minimizes PCB footprint and enables in-system programming and real-time debugging using TI's MSP-FET430UIF or compatible tools.
Is the MSP430G2744IRHA40T qualified for industrial temperature range operation?
Yes, the MSP430G2744IRHA40T is specified for operation across –40°C to +85°C ambient temperature, meeting industrial-grade reliability requirements. Its low-power design maintains stable performance across this range, with DCO calibration data stored in info memory to compensate for temperature-induced frequency drift.
