Product details
Overview
MSP430F2330IRHAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 8KB Flash, 1KB RAM, two 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. It operates from 1.8 V to 3.6 V and delivers active-mode current of 270 µA at 1 MHz/2.2 V, enabling battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F2330IRHAR datasheet, MSP430F2330IRHAR pinout, MSP430F2330IRHAR application, or MSP430F2330IRHAR equivalent, this page provides verified functional specifications, validated QFN-40 package pin mapping, confirmed low-power operating modes (LPM0–LPM4), and real-world use cases in energy-constrained embedded systems.
Technical Context
The MSP430F2330IRHAR integrates a digitally controlled oscillator (DCO) with factory-calibrated frequencies up to 16 MHz, enabling sub-1 µs wake-up from Standby Mode. Its clock system supports ACLK (from 32-kHz crystal or internal LF oscillator), SMCLK (DCO-derived), and MCLK (CPU clock), all configurable via BCSCTL registers.
Peripheral integration includes USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C), dual 16-bit timers with capture/compare/PWM capability, and Comparator_A+ for slope ADC or battery monitoring - all accessible through memory-mapped I/O and interrupt vectors located in 0xFFFE–0xFFC0.

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 |
|---|---|---|---|
| MSP430F2350IRHAR | 16KB Flash, 2KB RAM, same peripherals and pinout - no code size or RAM constraint impact | Preferred where firmware complexity requires >8KB Flash or larger data buffers | Select when future firmware expansion or real-time data buffering justifies higher memory cost |
| MSP430G2553IPW28 | 28-pin TSSOP, 16KB Flash, 512B RAM, lacks USCI_B0 (I²C) and Timer_B3 - different pin count and peripheral set | Suitable for simpler UART-only designs with lower I/O count and no I²C requirement | Choose only if design fits 28-pin layout and does not require dual USCI or second 16-bit timer |
Compared with MSP430F2350IRHAR, the MSP430F2330IRHAR trades Flash/RAM capacity for cost-sensitive deployments; versus MSP430G2553IPW28, it offers full USCI dual-interface support and 32 I/Os in QFN-40 - critical for complex sensor fusion or multi-peripheral coordination.

FAQ
What is the maximum operating frequency of the MSP430F2330IRHAR?
The MSP430F2330IRHAR supports a maximum system clock (MCLK) frequency of 16 MHz, achieved using the factory-calibrated digitally controlled oscillator (DCO). This frequency is confirmed in the SLAS518E datasheet Section "Basic Clock Module Configurations" and enables 62.5-ns instruction execution. The DCO calibration values for 16 MHz are stored in Flash Info Memory at addresses 0x10F9 (CALBC1_16MHZ) and 0x10F8 (CALBC0_16MHZ), allowing software to configure the DCO without external components. MSP430F2330IRHAR achieves full performance within its 1.8–3.6 V supply range.
Does the MSP430F2330IRHAR support I²C communication?
Yes, the MSP430F2330IRHAR supports I²C communication via its USCI_B0 module, which is explicitly documented in the "Universal Serial Communications Interface (USCI)" section of the SLAS518E datasheet. USCI_B0 implements full I²C master and slave functionality including clock stretching, 7-bit/10-bit addressing, and arbitration. Pin P3.1 (UCB0SIMO/UCB0SDA) and P3.2 (UCB0SOMI/UCB0SCL) serve as SDA and SCL, respectively. MSP430F2330IRHAR does not require external pull-up resistors to be enabled by default - they must be added per I²C bus requirements.
What development tools are compatible with the MSP430F2330IRHAR?
The MSP430F2330IRHAR is supported by TI's official development ecosystem, including the MSP-FET430U23X0 (designed specifically for RHA-package devices), MSP-FET430UIF (USB JTAG), and MSP-TS430QFN23X0 target board. These tools enable full-speed debugging, flash programming, and real-time register inspection via the standard 4-wire JTAG interface (TCK/TMS/TDI/TDO). MSP430F2330IRHAR also supports BSL-based UART programming using P1.1 and P2.2, as defined in Table 12 of SLAS518E.
Is the MSP430F2330IRHAR pin-compatible with other MSP430F23x0 variants?
Yes, the MSP430F2330IRHAR shares identical pinout, package dimensions, and electrical characteristics with MSP430F2350IRHAR and MSP430F2370IRHAR in the RHA (40-pin QFN) package, as confirmed in Table 1 ("Available Options") and the "Device Pinout, RHA Package" diagram of SLAS518E. All three variants use the same terminal functions and I/O mapping - enabling drop-in replacement where Flash/RAM requirements align. MSP430F2330IRHAR differs only in memory configuration (8KB/1KB), not in pin assignment or peripheral routing.
What low-power modes does the MSP430F2330IRHAR support?
The MSP430F2330IRHAR supports six operating modes: Active Mode (AM) and five software-selectable low-power modes (LPM0–LPM4), as detailed in the "Operating Modes" section of SLAS518E. LPM4 disables all clocks including ACLK and stops the crystal oscillator, achieving 0.1 µA current with RAM retention. Wake-up from any LPM mode takes less than 1 µs via interrupt, leveraging the DCO's fast stabilization. MSP430F2330IRHAR uses these modes to optimize energy efficiency in duty-cycled applications like wireless sensor nodes.
