Product details

Overview

MSP430F2252TRHARQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade 16-bit RISC microcontroller featuring 16KB + 256B flash memory, 512B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, dual 16-bit timers (Timer_A3 and Timer_B3), and a USCI module supporting UART/LIN, IrDA, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets low-power sensor front ends in LIN node applications.

For engineers reviewing the MSP430F2252TRHARQ1 datasheet, MSP430F2252TRHARQ1 pinout, MSP430F2252TRHARQ1 application, or MSP430F2252TRHARQ1 equivalent, key selection criteria include its QFN-40 RHA package, automotive qualification, ultra-low-power LPM4 mode (0.1 µA), calibrated DCO with ±1% tolerance, and integrated LIN-compliant UART with automatic baud rate detection.

Technical Context

The MSP430F2252TRHARQ1 implements a 16-bit RISC CPU with six low-power modes (AM, LPM0–LPM4), where wake-up from LPM3/LPM4 occurs in under 1 µs. Its clock system integrates a digitally controlled oscillator (DCO) with four factory-calibrated frequencies up to 16 MHz, plus support for LFXT1 (32 kHz crystal) and HFXT1 (up to 16 MHz crystal), external resistor (ROSC), or digital clock sources.

Peripherals include a 10-bit ADC10 with 12-channel analog input multiplexing (A0–A7, A12–A15), sample-and-hold, data transfer controller (DTC), and built-in temperature sensor; two 16-bit timers with capture/compare registers and shadow registers (Timer_B3); and a USCI module with dual independent channels-USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C).

Equivalent & Alternatives

The following parts are listed as comparable options for similar mixed-signal microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MSP430F2272TRHARQ1	32KB + 256B flash, 1KB RAM, same RHA package and peripheral set	Higher memory capacity supports larger LIN protocol stacks or additional diagnostic routines	Select when firmware complexity exceeds 16KB or future scalability is required
MSP430FR2152TRHAR	Ferroelectric RAM (FRAM) instead of flash; 3.75KB FRAM, 1KB RAM; no DCO calibration; different USCI implementation	Eliminates write endurance limits but lacks LIN-specific UART features and calibrated DCO	Prefer for high-write-cycle logging; avoid for LIN-critical automotive nodes due to missing automatic baud rate detection

Compared with MSP430F2272TRHARQ1, the MSP430F2252TRHARQ1 trades flash/RAM capacity for cost-sensitive LIN nodes, while the MSP430FR2152TRHAR replaces flash with FRAM for wearless data logging but sacrifices automotive LIN compliance and DCO precision.

FAQ

What automotive qualification level does the MSP430F2252TRHARQ1 meet?

The MSP430F2252TRHARQ1 is AEC-Q100 qualified to Grade 2, meaning it is rated for operation from −40°C to +105°C ambient temperature and has passed stress tests including HTOL, TC, and ESD per automotive reliability standards. This makes MSP430F2252TRHARQ1 suitable for under-hood and cabin-mounted electronic control units where thermal and electrical robustness are critical.

Does the MSP430F2252TRHARQ1 support LIN 2.2 protocol natively?

Yes, the MSP430F2252TRHARQ1 supports LIN 2.2 through its USCI_A0 module, which includes hardware-assisted LIN break detection, sync field handling, and automatic baud rate detection. The MSP430F2252TRHARQ1 does not require external LIN transceivers for basic node functionality, though a physical layer driver remains necessary for bus termination and voltage level translation.

How much current does the MSP430F2252TRHARQ1 draw in its lowest power mode?

In LPM4 (RAM retention, all clocks disabled), the MSP430F2252TRHARQ1 draws 0.1 µA at 2.2 V and 25°C. This ultra-low quiescent current enables multi-year operation on small batteries or energy-harvesting sources, making MSP430F2252TRHARQ1 ideal for always-on automotive sensors and telematics edge nodes.

Can the MSP430F2252TRHARQ1 operate without an external crystal?

Yes, the MSP430F2252TRHARQ1 can operate entirely from its internal digitally controlled oscillator (DCO), which is factory-calibrated to ±1% accuracy at 1 MHz, 4 MHz, 8 MHz, and 12 MHz. External crystals (LFXT1 or HFXT1) or a resistor (ROSC) are optional for higher precision or lower jitter; MSP430F2252TRHARQ1 retains full functionality-including LIN timing and ADC sampling-in DCO-only mode.

What debugging interface does the MSP430F2252TRHARQ1 use?

The MSP430F2252TRHARQ1 uses the two-wire Spy-Bi-Wire (SBW) interface via RST/NMI/SBWTDIO and TEST/SBWTCK pins for programming and debugging. This eliminates the need for a full 4-pin JTAG connector, simplifying PCB layout and reducing pin count. The MSP430F2252TRHARQ1 supports in-system programming, breakpoint setting, and register inspection through standard TI tools like MSP-FET and Code Composer Studio.
