Product details
Overview
MSP430F2272TRHARQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade 16-bit RISC microcontroller featuring 32KB+256B flash, 1KB RAM, 10-bit 200-ksps ADC with internal reference and DTC, dual 16-bit timers (Timer_A3 and Timer_B3), USCI with UART/LIN/I²C/SPI support, and ultra-low-power operation down to 0.1 µA in LPM4 mode. It targets battery-powered sensor nodes and LIN-compliant automotive subsystems.
For engineers reviewing the MSP430F2272TRHARQ1 datasheet, MSP430F2272TRHARQ1 pinout, MSP430F2272TRHARQ1 application, or MSP430F2272TRHARQ1 equivalent, key selection criteria include its QFN-40 RHA package, automotive temperature range (–40°C to 105°C), calibrated DCO with ±1% tolerance at 1 MHz, LIN-capable USCI_A0 with automatic baud-rate detection, and integrated brownout detector for robust power management in harsh environments.
Technical Context
The MSP430F2272TRHARQ1 implements a 16-bit CPU with seven addressing modes and constant generators for high code efficiency, operating across six power modes including LPM4 with full RAM retention at 0.1 µA. Its clock system integrates a digitally controlled oscillator (DCO) with four factory-calibrated frequencies up to 16 MHz, plus support for external crystals (LFXT1 up to 32 kHz, HFXT1 up to 16 MHz), resonators, and resistor-tuned DCO operation via P2.5/ROSC.
Peripherals are memory-mapped and accessible via standard instructions: the 10-bit ADC10 supports autoscan across 12 analog inputs (A0–A7, A12–A15) with sample-and-hold and data transfer controller; USCI_A0 provides LIN-compliant UART with auto-baud detection and IrDA encoding; USCI_B0 supports I²C master/slave and SPI; Timer_A3 and Timer_B3 each offer three capture/compare registers with shadow register support for Timer_B.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2252TRHARQ1 | 16KB+256B flash, 512B RAM, identical peripherals and pinout - lower memory density and RAM capacity. | Suitable for simpler LIN nodes or sensor interfaces with reduced firmware footprint and data buffering needs. | Select when application code size remains under 16KB and RAM usage stays below 512B to reduce cost without redesign. |
| TLV320AIC3104IRHBR | Dedicated audio codec IC with stereo ADC/DAC, not a microcontroller - lacks CPU, flash, timers, or general-purpose I/O. | Used only in audio signal chain applications requiring high-fidelity analog I/O, not embedded control or sensor processing. | Not a functional alternative; included only as a common mis-selection due to shared "TLV" prefix - verify device function before substitution. |
Compared with MSP430F2252TRHARQ1, the MSP430F2272TRHARQ1 offers double flash and RAM for complex firmware and data logging, while TLV320AIC3104IRHBR serves entirely different signal-chain roles and cannot replace the MCU's control, timing, or interface functions.

FAQ
What automotive qualification level does the MSP430F2272TRHARQ1 meet?
The MSP430F2272TRHARQ1 is AEC-Q100 Grade 2 qualified, certified for operation from –40°C to +105°C ambient temperature. This qualification covers stress testing for thermal cycling, humidity, mechanical shock, and ESD, ensuring reliability in under-hood and body-control applications. The device meets all requirements specified in the AEC-Q100 Rev-H standard for automotive microcontrollers.
Does the MSP430F2272TRHARQ1 support LIN 2.2 protocol natively?
Yes, the MSP430F2272TRHARQ1 supports LIN 2.2 through its USCI_A0 module, which implements enhanced UART with automatic baud-rate detection per ISO 14229. This allows the MSP430F2272TRHARQ1 to serve as a LIN master or slave node without external protocol translation hardware, provided external LIN transceiver (e.g., SN65HVDA100) is used for physical layer compliance.
What is the maximum ADC sampling rate achievable with the MSP430F2272TRHARQ1?
The MSP430F2272TRHARQ1 ADC10 achieves a maximum throughput of 200 ksps (kilo-samples per second) in single-channel mode with internal reference and no conversion delay. When using autoscan across multiple channels, effective rate depends on sampling capacitor recharge time and clock configuration but remains within the 200-ksps specification limit under recommended operating conditions.
Can the MSP430F2272TRHARQ1 operate without an external crystal?
Yes, the MSP430F2272TRHARQ1 can operate without an external crystal by using its internal digitally controlled oscillator (DCO), which is factory-calibrated to ±1% accuracy at 1 MHz. The DCO supports frequencies up to 16 MHz and can be tuned further using the external resistor on P2.5/ROSC, enabling crystal-free designs for cost-sensitive automotive applications.
How many I/O pins does the MSP430F2272TRHARQ1 provide in the RHA package?
The MSP430F2272TRHARQ1 in the 40-pin QFN RHA package provides 32 general-purpose I/O pins distributed across Ports P1–P4 (8 pins each), all configurable with programmable pullup/pulldown resistors and interrupt capability. Pins P1.0–P1.7, P2.0–P2.7, P3.0–P3.7, and P4.0–P4.7 are fully functional I/O, excluding dedicated power/ground and debug pins.
