Product details
Overview
MSP430F233TRGCT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 8KB+256B flash memory, 1KB RAM, a 12-bit ADC with 8 channels, two 16-bit timers (Timer_A with three capture/compare registers and Timer_B with three registers), one USCI module (UART/IrDA/SPI + I²C), on-chip comparator, and supply voltage supervisor - deployed in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F233TRGCT datasheet, MSP430F233TRGCT pinout, MSP430F233TRGCT application, or MSP430F233TRGCT equivalent, key selection criteria include its 64-pin QFN (RGC) package, 1.8–3.6 V operation, sub-1 µs wake-up time, ADC12 resolution and channel count, and USCI_A0-only serial interface configuration versus higher-pin-count variants.
Technical Context
The MSP430F233TRGCT implements a 16-bit CPU with constant generators and a calibrated DCO enabling active-mode operation up to 16 MHz. Its clock system integrates internal LF oscillator, 32-kHz crystal support (XT1), optional high-frequency crystal (XT2), and programmable MCLK/SMCLK/ACLK routing.
It features a single USCI_A0 module supporting UART with auto-baud detection and IrDA encoding/decoding, plus SPI and I²C modes; no USCI_B or USCI_A1 functionality is present. The ADC12 includes internal reference, sample-and-hold, and autoscan - but lacks the second USCI and expanded Timer_B found in MSP430F24x devices.

FAQ
What is the maximum operating frequency of the MSP430F233TRGCT?
The MSP430F233TRGCT supports a maximum CPU clock frequency of 16 MHz, achievable using the internal digitally controlled oscillator (DCO) with factory calibration or external crystal sources. This allows execution of instructions in 62.5 ns cycles, enabling real-time processing in sensor fusion and control loops without external clock components.
Does the MSP430F233TRGCT include USB or CAN interface capability?
No, the MSP430F233TRGCT does not include native USB or CAN interface hardware. It provides only one USCI_A0 module supporting UART, IrDA, SPI, and I²C protocols. For CAN communication, an external transceiver paired with bit-banged or USCI-based software CAN stack is required; USB requires external PHY and host-side driver support.
How many analog input channels does the ADC12 module support on the MSP430F233TRGCT?
The ADC12 module on the MSP430F233TRGCT supports eight analog input channels (A0–A7), accessible via P6.0 through P6.7. All channels are configurable for single-ended or differential acquisition, and the module includes internal reference voltage generation, sample-and-hold, and autoscan functionality - confirmed in the SLAS547I datasheet section for MSP430F23x devices.
Is the MSP430F233TRGCT pin-compatible with the MSP430F247TRGCT?
Yes, the MSP430F233TRGCT and MSP430F247TRGCT share identical 64-pin QFN (RGC) packaging and pin assignments, including power, ground, JTAG, and all I/O functions. However, unused pins on the MSP430F233TRGCT (e.g., USCI_B0 signals) are no-connects - allowing drop-in replacement only when firmware and PCB design do not rely on the enhanced peripherals of the F247 variant.
What debug interface does the MSP430F233TRGCT support?
The MSP430F233TRGCT supports JTAG debugging via the standard 4-pin interface (TCK, TDO/TDI, TMS, and TDI/TCLK), enabled by its integrated Embedded Emulation Module (EEM). It is compatible with TI's MSP-FET430UIF debugger and Code Composer Studio IDE - permitting full-speed execution control, breakpoint setting, and memory inspection during development and validation.
