Product details
Overview
MSP430F2252IRHAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16 KB + 256 B flash memory, 512 B RAM, a 10-bit 200-ksps ADC with internal reference and autoscan, dual 16-bit timers (Timer_A3 and Timer_B3), and USCI modules supporting UART/LIN, IrDA, SPI, and I²C - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2252IRHAT datasheet, MSP430F2252IRHAT pinout, MSP430F2252IRHAT application, or MSP430F2252IRHAT equivalent, key selection criteria include its 1.8–3.6 V supply range, sub-1 µs wake-up from LPM4, integrated brownout detector, Spy-Bi-Wire debug interface, and QFN-40 package compatibility with space-constrained PCB layouts.
Technical Context
The MSP430F2252IRHAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its basic clock system supports internal DCO (calibrated to ±1% at 1 MHz), 32-kHz crystal, HF crystal up to 16 MHz, external digital clock, or resistor-controlled oscillator via ROSC pin.
It integrates two independent USCI modules: USCI_A0 for enhanced UART (with auto-baud detection), IrDA, and SPI; and USCI_B0 for SPI and I²C. Unlike the MSP430F22x4 family members, the MSP430F2252IRHAT does not include operational amplifiers - confirmed by device-specific feature tables and pin function listings.

FAQ
What is the maximum operating frequency of the MSP430F2252IRHAT?
The MSP430F2252IRHAT supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal digitally controlled oscillator (DCO) calibrated to ±1% accuracy or an external HF crystal up to 16 MHz. This allows execution of 16 million instructions per second with 62.5-ns cycle time, while maintaining ultra-low power consumption in active mode.
Does the MSP430F2252IRHAT include operational amplifiers?
No, the MSP430F2252IRHAT does not include operational amplifiers. Operational amplifiers are exclusive to the MSP430F22x4 series (e.g., MSP430F2254IRHAT). The MSP430F2252IRHAT is part of the MSP430F22x2 family, which omits OA0 and OA1 - confirmed by functional block diagrams, feature lists, and pin function tables in the SLAS504G datasheet.
What debug interface does the MSP430F2252IRHAT support?
The MSP430F2252IRHAT supports the Spy-Bi-Wire (SBW) interface using pins TEST/SBWTCK (Pin 1) and RST/NMI/SBWTDIO (Pin 6). This 2-wire debug protocol enables full-speed programming, breakpoint setting, and real-time variable inspection without requiring a 4-pin JTAG header - reducing PCB footprint and BOM cost.
Can the MSP430F2252IRHAT operate from a single 1.8 V supply?
Yes, the MSP430F2252IRHAT operates across a supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including flash programming, ADC operation, and real-time clock capability - verified in the electrical characteristics table of SLAS504G. This enables direct use with single-cell lithium batteries without voltage regulation.
What is the ADC resolution and sampling rate of the MSP430F2252IRHAT?
The MSP430F2252IRHAT integrates a 10-bit successive-approximation ADC (ADC10) with a maximum sampling rate of 200 ksps. It supports 12 analog input channels, internal reference (1.5 V or 2.5 V), sample-and-hold, autoscan mode, and Data Transfer Controller (DTC) for autonomous memory writes - eliminating CPU intervention during burst sampling sequences.
