Texas Instruments MSP430F2252TRHAT

Overview

MSP430F2252TRHAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal 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 Universal Serial Communication Interface supporting UART/LIN, IrDA, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor acquisition and embedded control applications.

For engineers reviewing the MSP430F2252TRHAT datasheet, MSP430F2252TRHAT pinout, MSP430F2252TRHAT application, or MSP430F2252TRHAT equivalent, key selection considerations include its 40-pin QFN (RHA) package, -40°C to 105°C temperature grade, integrated brownout detector, sub-1-µs wake-up from standby mode, and absence of operational amplifiers (distinguishing it from the F22x4 series).

Technical Context

The MSP430F2252TRHAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling efficient code execution in ultra-low-power environments. Its basic clock system supports internal DCO (calibrated to ±1% at 1 MHz, 2.2 V), 32-kHz crystal, and HF crystal up to 16 MHz - all configurable via software-controlled clock modules.

It integrates two independent 16-bit timers with capture/compare registers, a USCI module with dual serial interfaces (USCI_A0 for UART/IrDA/SPI and USCI_B0 for SPI/I²C), and an ADC10 with data transfer controller (DTC) for autonomous analog-to-digital conversion without CPU intervention.

FAQ

What is the maximum operating frequency of the MSP430F2252TRHAT?

The MSP430F2252TRHAT supports a maximum system clock (MCLK) frequency of 16 MHz using an external high-frequency crystal or resonator. Its internal digitally controlled oscillator (DCO) is factory-calibrated to ±1% accuracy at 1 MHz and 2.2 V, enabling reliable operation without external timing components in many low-speed applications. The device achieves a 62.5-ns instruction cycle time at 16 MHz.

Does the MSP430F2252TRHAT include operational amplifiers?

No, the MSP430F2252TRHAT does not include operational amplifiers. It belongs to the MSP430F22x2 series, which omits the two configurable op-amps present in the MSP430F22x4 variants (e.g., MSP430F2254TRHAT). This distinction is confirmed in the device family datasheet SLAS504G, where op-amp functionality is explicitly marked "MSP430F22x4 Only".

What package type and pin count does the MSP430F2252TRHAT use?

The MSP430F2252TRHAT uses a 40-pin QFN package designated RHA, measuring 6 mm × 6 mm with 0.5 mm pitch and an exposed thermal pad. This matches the pinout and footprint of other RHA-packaged MSP430F22x2 devices, including MSP430F2232TRHAT and MSP430F2272TRHAT, enabling direct substitution in compatible layouts.

How does the MSP430F2252TRHAT handle analog-to-digital conversion without CPU involvement?

The MSP430F2252TRHAT integrates a Data Transfer Controller (DTC) that automatically moves ADC10 conversion results to memory buffers upon completion - eliminating CPU polling or interrupt servicing for each sample. When combined with ADC autoscan mode, the DTC enables fully autonomous multi-channel acquisition sequences, reducing active CPU time and overall system power consumption.

Is the MSP430F2252TRHAT supported by modern development tools?

Yes, the MSP430F2252TRHAT is fully supported by Texas Instruments' current development ecosystem, including Code Composer Studio v12+, MSP430Ware peripheral driver library, and the MSP-FET430UIF debugger. Its Spy-Bi-Wire interface is compatible with all TI-certified programmers, and the device is listed in TI's official device support database with validated compiler toolchains and example projects.
