Texas Instruments MSP430F2330IYFFT

Overview

MSP430F2330IYFFT 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 targets battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430F2330IYFFT datasheet, MSP430F2330IYFFT pinout, MSP430F2330IYFFT application, or MSP430F2330IYFFT equivalent, key selection criteria include its 40-pin QFN (YFF) package, sub-1 µs wake-up from standby mode (0.7 µA), integrated DCO with factory-calibrated frequencies up to 16 MHz, and dual USCI modules for concurrent asynchronous and synchronous communication.

Technical Context

The MSP430F2330IYFFT implements a 16-bit CPU with seven addressing modes and 51 instructions, paired with a basic clock system supporting ACLK (32 kHz crystal or internal LF oscillator), SMCLK (DCO up to 16 MHz), and MCLK. Its power architecture enables six operating modes-including LPM4 (0.1 µA RAM retention)-with fast transition via DCO stabilization in <1 µs.

Peripherals are memory-mapped and accessible via all CPU instructions. The USCI_A0 module handles UART (with LIN auto-baud), IrDA, and SPI; USCI_B0 supports SPI and I²C. Timer_A3 and Timer_B3 each provide three capture/compare registers, PWM generation, and interrupt-capable event timing.

FAQ

What is the maximum operating frequency of the MSP430F2330IYFFT?

The MSP430F2330IYFFT supports a maximum system clock (MCLK) of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO). This frequency is validated across the full temperature range (–40°C to +85°C) and supply voltage (1.8 V to 3.6 V), enabling deterministic real-time performance in timing-critical applications without requiring an external crystal.

Does the MSP430F2330IYFFT support I²C communication?

Yes, the MSP430F2330IYFFT supports I²C communication through its USCI_B0 module. This module implements full I²C master and slave functionality with programmable clock speed, 7-bit and 10-bit addressing, and clock stretching-enabling reliable interfacing with sensors, EEPROMs, and other I²C peripherals without external level shifters or protocol translators.

What package type is used for the MSP430F2330IYFFT?

The MSP430F2330IYFFT uses a 40-pin QFN package (YFF), measuring 3.2 mm × 3.2 mm with 0.5 mm pitch and an exposed thermal pad. This compact, surface-mount package is optimized for space-constrained PCB layouts and provides robust thermal performance when the pad is soldered to a solid ground plane.

How much Flash and RAM memory does the MSP430F2330IYFFT include?

The MSP430F2330IYFFT integrates 8KB of main Flash memory for program storage, 256 bytes of information Flash memory for calibration data and user constants, and 1KB of SRAM for runtime variables and stack operations. This memory configuration balances code capacity and data handling for mid-complexity embedded applications such as sensor hubs and portable instrumentation.

Can the MSP430F2330IYFFT perform analog-to-digital conversion without a dedicated ADC?

Yes, the MSP430F2330IYFFT can perform analog-to-digital conversion using its Comparator_A+ module in slope ADC mode. By combining the comparator with Timer_A3 to generate a linear ramp, the device achieves effective 10–12-bit resolution for slow-varying signals like temperature or battery voltage-eliminating the need for external ADC components in cost-sensitive designs.
