Product details
Overview
MSP430F2330IRHAT 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, SPI, I²C, and IrDA, and an on-chip analog comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F2330IRHAT datasheet, MSP430F2330IRHAT pinout, MSP430F2330IRHAT application, or MSP430F2330IRHAT equivalent, key selection criteria include its 40-pin QFN (RHA) package, sub-1µs wake-up from standby mode, integrated DCO with factory-calibrated frequencies up to 16 MHz, and dual USCI modules for concurrent asynchronous and synchronous serial communication.
Technical Context
The MSP430F2330IRHAT implements a 16-bit CPU with seven addressing modes and a hardware multiplier supporting signed/unsigned 16×16, 16×8, and 8×8 operations. Its clock system integrates a digitally controlled oscillator (DCO), low-frequency internal oscillator, and external crystal support (32 kHz LF and up to 16 MHz HF).
It features five software-selectable low-power modes (LPM0–LPM4), with active-mode current of 270 µA at 1 MHz/2.2 V and standby-mode current of 0.7 µA. The device includes 32 general-purpose I/O pins across four 8-bit ports, each with individually programmable pullup/pulldown resistors and edge-selectable interrupts on P1/P2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and constant generators; enables single-cycle register operations and high code efficiency. |
| Memory | 8KB + 256B Flash (main + info memory), 1KB RAM; supports in-system programming via JTAG or BSL UART interface. |
| Power Supply | 1.8 V to 3.6 V operation; enables direct use with single Li-ion or dual alkaline cells without regulation. |
| Ultra-Low Power | Active mode: 270 µA @ 1 MHz, 2.2 V; Standby: 0.7 µA; Off mode (RAM retention): 0.1 µA - extends battery life in intermittent-sensing applications. |
| Timers | Timer_A3 (3 capture/compare registers) and Timer_B3 (3 capture/compare registers); support PWM generation, input capture, interval timing, and interrupt-driven event handling. |
| Serial Interfaces | USCI_A0 (UART, IrDA, SPI) and USCI_B0 (SPI, I²C); enables simultaneous wired communication protocols without external transceivers. |

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 |
|---|---|---|---|
| MSP430F2350IRHAT | 16KB Flash, 2KB RAM, same peripherals and package; higher memory capacity but identical power profile and pinout. | Suitable where firmware complexity requires >8KB code space or larger data buffers for protocol stacks. | Select when future firmware expansion or real-time logging demands additional Flash/RAM without changing PCB layout. |
| MSP430G2553IPW28 | 28-pin TSSOP, 16KB Flash, 512B RAM, no USCI_B0 (I²C), only USCI_A0; lower pin count and reduced analog feature set. | Targeted at simpler, lower-cost sensor endpoints where I²C is not required and board space is constrained. | Choose for cost-sensitive, space-limited designs where dual USCI and full comparator functionality are unnecessary. |
Compared with MSP430F2330IRHAT, the MSP430F2350IRHAT offers scalable memory within identical power/performance/package constraints, while the MSP430G2553IPW28 trades peripheral richness and pin count for lower unit cost and smaller footprint in less demanding applications.

The MSP430F2330IRHAT supports a maximum system clock (MCLK) of 16 MHz, achieved using the factory-calibrated digitally controlled oscillator (DCO) or an external high-frequency crystal up to 16 MHz. This frequency is confirmed in the SLAS518E datasheet Section 12 (Oscillator and System Clock) and enables deterministic real-time response in time-critical sensor applications.
Does the MSP430F2330IRHAT support I²C communication?
Yes, the MSP430F2330IRHAT supports I²C communication via USCI_B0 module, which is explicitly documented in the "Universal Serial Communications Interface (USCI)" section of the SLAS518E datasheet. USCI_B0 provides full master/slave I²C functionality including clock stretching, 7-bit/10-bit addressing, and status flag reporting.
What debug interfaces are supported by the MSP430F2330IRHAT?
The MSP430F2330IRHAT supports JTAG-based debugging and programming through dedicated TCK, TMS, TDI, and TDO pins (pins 37, 36, 35, and 34 respectively). It also includes an on-chip Emulation Module (EEM) compatible with TI's MSP-FET430U23X0 and MSP-FET430UIF tools, enabling full-speed breakpoints and real-time variable inspection.
How much Flash and RAM does the MSP430F2330IRHAT contain?
The MSP430F2330IRHAT contains 8KB of main Flash memory plus 256B of information Flash memory (used for calibration data and BSL), and 1KB of RAM. These values are specified in Table 11 ("Memory Organization") of the SLAS518E datasheet and define the executable code size and runtime data buffer capacity.
Is the MSP430F2330IRHAT pin-compatible with other MSP430F23x0 variants?
Yes, the MSP430F2330IRHAT shares identical pinout and package (40-pin QFN, RHA) with MSP430F2350IRHAT and MSP430F2370IRHAT, as confirmed in Table 1 ("Available Options") and the "Device Pinout, RHA Package" diagram in SLAS518E.
