Product details
Overview
MSP430F2330IYFFR 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 MSP430F2330IYFFR datasheet, MSP430F2330IYFFR pinout, MSP430F2330IYFFR application, or MSP430F2330IYFFR equivalent, key selection criteria include its 40-pin QFN (YFF) package, integrated DCO with factory-calibrated frequencies up to 16 MHz, LIN-capable USCI_A0 with auto-baudrate detection, and ultra-fast wake-up (<1 µs) from standby mode.
Technical Context
The MSP430F2330IYFFR implements a 16-bit RISC CPU with seven addressing modes and 51 instructions, paired with a basic clock system supporting internal DCO (calibrated at 1/8/12/16 MHz), external crystals (32 kHz LF and up to 16 MHz HF), and resistor-controlled oscillation. Its memory map includes 8KB main Flash, 256B information Flash, 1KB RAM, and 1KB ROM boot loader.
Peripheral integration centers on dual 16-bit timers with capture/compare/PWM capability, USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C), Comparator_A+ for slope ADC or voltage monitoring, and hardware multiplier for signed/unsigned 16×16 operations - all accessible via unified data/address/control buses and interruptible with priority-based vectoring.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2350IYFFR | 16KB Flash, 2KB RAM, same peripherals and package - double memory capacity with identical pinout and timing | Suitable for applications requiring larger firmware image or extended data logging buffers | Select when future firmware growth or runtime data storage exceeds 8KB Flash/1KB RAM limits |
| MSP430F2274IRHA | 49-pin BGA (RHA), 16KB Flash, 1KB RAM, lacks USCI_B0 I²C support - different package and reduced serial interface set | Better suited for space-constrained PCBs where BGA placement is acceptable and I²C is not required | Choose only if BGA footprint is preferred and I²C connectivity is unnecessary; not pin-compatible |
Compared with MSP430F2350IYFFR, the MSP430F2330IYFFR trades memory headroom for cost-sensitive deployments; versus MSP430F2274IRHA, it retains full USCI dual-interface capability and offers QFN manufacturability with verified thermal performance.

FAQ
What is the maximum operating frequency of the MSP430F2330IYFFR?
The MSP430F2330IYFFR supports a maximum system clock (MCLK) of 16 MHz, achieved using the internal digitally controlled oscillator (DCO) with factory-calibrated settings stored in information memory segment A. External crystal sources up to 16 MHz are also supported, but the DCO provides fastest wake-up and eliminates external components.
Does the MSP430F2330IYFFR support I²C communication?
Yes, the MSP430F2330IYFFR supports I²C communication through its USCI_B0 module, which implements full I²C master/slave functionality including clock stretching, 7-bit/10-bit addressing, and arbitration. The dedicated I²C pins are P3.1 (UCB0SDA) and P3.2 (UCB0SCL) in the YFF package.
How is flash memory programmed on the MSP430F2330IYFFR?
Flash memory on the MSP430F2330IYFFR can be programmed via three methods: JTAG interface using MSP-FET430UIF, onboard bootstrap loader (BSL) accessed over UART using P1.1/P2.2, or in-system by the CPU using FCTL registers. All methods support byte/word writes and segment-level erase.
What is the purpose of the exposed thermal pad on the YFF package of the MSP430F2330IYFFR?
The exposed thermal pad on the MSP430F2330IYFFR's 40-pin QFN package must be soldered to a PCB copper pour connected to D/AVSS (pin B1). It improves thermal dissipation during sustained active-mode operation and enhances electrical stability by reducing ground impedance for analog and digital sections.
Can the MSP430F2330IYFFR operate without an external crystal?
Yes, the MSP430F2330IYFFR can operate entirely without external crystals using its internal digitally controlled oscillator (DCO), which is factory-calibrated at 1/8/12/16 MHz with ±1% accuracy. This enables crystal-free designs while maintaining sufficient timing precision for UART, SPI, and real-time control tasks.
