Product details
Overview
MSP430F2370IRHAT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32 KB + 256 B flash memory, 2 KB RAM, dual 16-bit timers (Timer_A3 and Timer_B3), a universal serial communication interface (USCI) supporting UART, IrDA, SPI, and I²C, and an on-chip analog comparator for slope A/D conversion - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F2370IRHAT datasheet, MSP430F2370IRHAT pinout, MSP430F2370IRHAT application, or MSP430F2370IRHAT equivalent, key selection criteria include its 1.8–3.6 V supply range, sub-1 µs wake-up from standby mode, calibrated DCO up to 16 MHz, and QFN-40 package compatibility with space-constrained embedded designs.
Technical Context
The MSP430F2370IRHAT implements a 16-bit RISC CPU with seven addressing modes and 16 general-purpose registers, enabling single-cycle register-to-register execution. Its clock system integrates a digitally controlled oscillator (DCO) with factory-calibrated frequencies (1/8/12/16 MHz), plus support for external LF/HF crystals and resistor-based tuning.
Peripherals include USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C), two independent 16-bit timers with three capture/compare registers each, and Comparator_A+ with eight selectable inputs - all accessible via memory-mapped I/O and interrupt-driven operation across six low-power modes (LPM0–LPM4).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F247TRHAT | 60 KB flash, 4 KB RAM, same RHA package; adds hardware multiplier and enhanced USCI features | Suitable for applications requiring complex math (e.g., FFT-based vibration analysis) or higher firmware headroom | Select when future firmware expansion or real-time signal processing is anticipated - no PCB change needed |
| MSP430FR2355TRHAT | Ferroelectric RAM (6.5 KB FRAM), 2 KB SRAM, 32 KB program memory; lower write energy, infinite endurance | Better suited for frequent data logging or parameter storage where flash wear-out is a concern | Choose for high-cycle data buffering (e.g., utility meter pulse counting) - requires minor firmware adaptation for FRAM access |
Compared with MSP430F2370IRHAT, MSP430F247TRHAT offers greater memory headroom for feature-rich firmware, while MSP430FR2355TRHAT replaces flash with FRAM to eliminate write endurance limits - both retain identical pinout and core peripheral set for seamless migration.

FAQ
What is the maximum operating frequency of the MSP430F2370IRHAT?
The MSP430F2370IRHAT supports a maximum system clock (MCLK) of 16 MHz, achieved using the factory-calibrated digitally controlled oscillator (DCO). This frequency is confirmed in the SLAS518E datasheet Section 12 (Oscillator and System Clock) and enables 62.5-ns instruction cycle time for real-time processing tasks within the MSP430F2370IRHAT's ultra-low-power envelope.
Does the MSP430F2370IRHAT support hardware UART with automatic baudrate detection?
Yes, the MSP430F2370IRHAT's USCI_A0 module supports enhanced UART with automatic baudrate detection (LIN-compliant), as documented in the SLAS518E datasheet Section 1 (Features) and Section 15 (Universal Serial Communications Interface). This capability allows the MSP430F2370IRHAT to synchronize to incoming LIN bus frames without prior knowledge of the master's baud rate.
How much flash memory is allocated to information memory in the MSP430F2370IRHAT?
Within the MSP430F2370IRHAT's 32 KB main flash, 256 bytes are reserved as information memory (segments A–D), located at address range 0x10FF–0x1000. As specified in Table 11 (Memory Organization) of SLAS518E, this region stores factory calibration data (segment A), BSL password, and user-configurable parameters - all accessible via standard flash programming commands.
What low-power modes are available on the MSP430F2370IRHAT, and what is the lowest current consumption?
The MSP430F2370IRHAT provides six operating modes: Active Mode and five software-selectable low-power modes (LPM0–LPM4). The lowest current is 0.1 µA in Off mode with RAM retention (LPM4), verified in Section 8 (Operating Modes) and Section 1 (Features) of SLAS518E - ideal for long-duration sleep states in energy-harvesting or battery-backed systems using the MSP430F2370IRHAT.
Is the MSP430F2370IRHAT pin-compatible with other devices in the MSP430F23x0 family?
Yes, the MSP430F2370IRHAT shares identical pinout and electrical characteristics with MSP430F2330IRHAT and MSP430F2350IRHAT in the RHA (40-pin QFN) package, as confirmed in Table 1 (Available Options) and the Device Pinout diagram (page 3) of SLAS518E. This allows direct substitution within the same footprint when scaling flash/RAM requirements without layout revision.
