Product details
Overview
MSP430F2350IRHAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 16KB+256B flash, 2KB RAM, dual 16-bit timers (Timer_A3 and Timer_B3), a universal serial communication interface (USCI) supporting UART/IrDA/SPI/I²C, and an on-chip analog comparator - deployed in battery-powered sensor nodes and portable instrumentation requiring sub-1µs wake-up and <0.1µA off-mode current.
For engineers reviewing the MSP430F2350IRHAR datasheet, MSP430F2350IRHAR pinout, MSP430F2350IRHAR application, or MSP430F2350IRHAR equivalent, this page delivers verified electrical specs, QFN-40 package terminal mapping, low-power operating mode behavior, USCI peripheral configuration options, and validated alternative microcontrollers for migration or second-sourcing.
Technical Context
The MSP430F2350IRHAR implements a 16-bit CPU with seven addressing modes and 51 instructions, integrated with a digitally controlled oscillator (DCO) factory-calibrated to ±1% at 1/8/12/16 MHz, enabling sub-1µs wake-up from LPM4. Its clock system supports ACLK (32 kHz crystal or internal LF), SMCLK (DCO-derived), and MCLK (system clock).
Peripherals include USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C), two independent 16-bit timers each with three capture/compare registers, a hardware multiplier for signed/unsigned 16×16 operations, and Comparator_A+ supporting slope ADC and battery monitoring - all accessible via memory-mapped I/O with full interrupt vectoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F247TRHAR | 32KB flash, 2KB RAM, same RHA package; adds 12-bit ADC with 8 channels | Required when high-resolution analog sensing (e.g., multi-channel thermistor arrays) is needed alongside existing peripherals | Select if ADC capability is mandatory and board layout allows identical footprint |
| MSP430G2553IRHB32R | 16KB flash, 512B RAM, 32-pin QFN; lacks Timer_B, USCI_B0, and comparator; lower cost | Suitable for simpler UART-only control tasks where dual timers and I²C are unnecessary | Choose for cost-sensitive, functionally reduced designs with no requirement for I²C or advanced PWM |
Compared with MSP430F2350IRHAR, MSP430F247TRHAR adds essential ADC functionality at identical pinout and power profile, while MSP430G2553IRHB32R reduces feature set and memory to lower BOM cost - making it viable only when Timer_B, USCI_B0, and Comparator_A+ are unused.

FAQ
What is the maximum operating frequency of the MSP430F2350IRHAR?
The MSP430F2350IRHAR supports up to 16 MHz system clock via its digitally controlled oscillator (DCO), factory-calibrated to ±1% accuracy at 1/8/12/16 MHz. This enables deterministic 62.5-ns instruction cycles without requiring an external high-frequency crystal - critical for timing-critical sensor sampling or communication protocols.
Does the MSP430F2350IRHAR include an analog-to-digital converter (ADC)?
No, the MSP430F2350IRHAR does not integrate a dedicated ADC. It features Comparator_A+ for slope ADC implementation and analog threshold detection, but requires external ADC components or external analog front-end circuits for digitizing continuous analog signals - unlike later MSP430 generations such as the F24x or G2xx families.
Which development tools are officially supported for the MSP430F2350IRHAR?
Texas Instruments officially supports the MSP-FET430U23X0 (RHA-targeted JTAG emulator), MSP-TS430QFN23X0 (QFN-40 target socket board), and MSP-GANG430 (production programmer). The device's Embedded Emulation Module (EEM) ensures full debug visibility, including real-time register inspection and breakpoint control during active or low-power operation of MSP430F2350IRHAR.
Can the MSP430F2350IRHAR operate from a single 1.8V supply?
Yes, the MSP430F2350IRHAR is fully specified to operate across 1.8 V to 3.6 V, including stable execution at minimum 1.8 V. All peripherals - including USCI modules, timers, and comparator - remain functional within this range, enabling direct compatibility with single-cell lithium primary batteries or regulated 1.8V rails in space-constrained designs.
How is flash memory programmed on the MSP430F2350IRHAR?
Flash programming on the MSP430F2350IRHAR is supported via three methods: JTAG interface (using MSP-FET430U23X0), onboard bootstrap loader (BSL) over UART using P1.1/P2.2 pins, or in-system programming by the CPU itself. All methods support byte- and word-level writes, segment erasure, and security fuse locking - ensuring flexibility for prototyping, field updates, and production programming of MSP430F2350IRHAR.
