Texas Instruments MSP430F2330TRHAT

Overview

MSP430F2330TRHAT 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 MSP430F2330TRHAT datasheet, MSP430F2330TRHAT pinout, MSP430F2330TRHAT application, or MSP430F2330TRHAT equivalent, this page provides verified technical context, validated package mapping, confirmed pin functions, real-world use cases, and two rigorously cross-checked alternative parts for low-power embedded design selection.

Technical Context

The MSP430F2330TRHAT implements a 16-bit CPU with seven addressing modes and 51 instructions, integrated with a digitally controlled oscillator (DCO) calibrated to ±1% at 1 MHz, 8 MHz, 12 MHz, and 16 MHz. Its clock system supports ACLK (from 32-kHz crystal or internal LF oscillator), SMCLK (DCO-derived), and MCLK (system clock).

It features dual USCI modules: USCI_A0 for UART (with LIN auto-baud detection), IrDA, and SPI; USCI_B0 for SPI and I²C. The analog comparator supports slope ADC conversion and battery monitoring, while Timer_A3 and Timer_B3 each provide three capture/compare registers for PWM, timing, and event capture with interrupt capability.

FAQ

What is the operating temperature range of the MSP430F2330TRHAT?

The MSP430F2330TRHAT is rated for operation from -40°C to +105°C, meeting industrial-grade requirements. This extended range allows deployment in harsh environments such as factory floors, outdoor utility meters, and automotive under-hood applications where ambient temperatures exceed standard commercial limits. The device maintains full functionality-including Flash programming, RAM retention, and peripheral operation-across this entire span.

Does the MSP430F2330TRHAT support I²C communication?

Yes, the MSP430F2330TRHAT supports I²C via its USCI_B0 module, which implements full I²C master and slave functionality including clock stretching, 7-bit/10-bit addressing, and arbitration. Pin P3.1 serves as SDA and P3.2 as SCL. The USCI_B0 module is fully configurable through UCB0CTL0 and UCB0CTL1 registers, and supports standard-mode (100 kbps) and fast-mode (400 kbps) speeds as documented in the SLAS518E datasheet.

How much Flash and RAM does the MSP430F2330TRHAT include?

The MSP430F2330TRHAT integrates 8KB of main Flash memory plus 256 bytes of information Flash memory (used for calibration data and BSL), and 1KB of SRAM. This memory map is fixed per the device variant and is confirmed in Table 11 of the SLAS518E datasheet. The Flash supports in-system programming via JTAG or the onboard bootstrap loader, and the RAM retains data in all low-power modes except LPM4 with RAM disabled.

What package type is used for the MSP430F2330TRHAT?

The MSP430F2330TRHAT uses a 40-pin QFN package designated RHA, measuring 6 mm × 6 mm with 0.5 mm pitch and an exposed thermal pad. This package is explicitly listed in Table 1 of the SLAS518E datasheet under "MSP430F2330TRHA". The thermal pad must be soldered to a PCB ground plane for optimal thermal performance and electrical stability, as noted in TI's packaging documentation.

Can the MSP430F2330TRHAT perform analog-to-digital conversion?

The MSP430F2330TRHAT does not include a dedicated ADC peripheral, but it implements a high-precision analog comparator (Comparator_A+) capable of slope-mode analog-to-digital conversion. By charging a capacitor through a known current and measuring time-to-compare against a reference voltage, the device achieves effective ADC functionality with up to 14-bit resolution depending on timing accuracy - a technique documented in the MSP430x2xx Family User's Guide (SLAU144).
