Texas Instruments MSP430F2112TRTVR

Overview

MSP430F2112TRTVR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 2 KB flash, 256 B RAM, a 10-bit 200-ksps ADC with internal reference and DTC, two 16-bit timers (Timer0_A3 with three capture/compare registers, Timer1_A2 with two), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and a comparator for slope A/D conversion - deployed in battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430F2112TRTVR datasheet, MSP430F2112TRTVR pinout, MSP430F2112TRTVR application, or MSP430F2112TRTVR equivalent, key selection criteria include its -40°C to 105°C extended temperature rating, 32-pin QFN (RTV) package with 24 GPIOs, sub-1 µs wake-up from 0.1 µA off-mode, and integrated DCO calibrated to ±1% at 1–16 MHz - critical for energy-constrained embedded timing and analog-sensing designs.

Technical Context

The MSP430F2112TRTVR implements a 16-bit CPU with seven addressing modes and constant generators for high code efficiency, paired with five software-selectable low-power modes (LPM0–LPM4) optimized for extended battery life. Its basic clock module integrates a digitally controlled oscillator (DCO), 32-kHz crystal support, and internal LF oscillator - enabling fast wake-up and flexible clock sourcing.

Peripherals are memory-mapped and accessible via all CPU instructions. The ADC10 includes autoscan, sample-and-hold, and a data transfer controller (DTC) that autonomously stores conversion results without CPU intervention. The comparator_A+ supports both analog signal comparison and slope-based A/D conversion, while USCI modules provide protocol-flexible serial communication with LIN auto-baudrate detection.

FAQ

What is the maximum operating frequency of the MSP430F2112TRTVR?

The MSP430F2112TRTVR supports a maximum system clock (MCLK) of 16 MHz, achieved via its internal digitally controlled oscillator (DCO) with four factory-calibrated frequencies (1/8/12/16 MHz) accurate to ±1%. External crystals up to 16 MHz are also supported on XIN/XOUT pins. This frequency governs CPU execution speed, timer resolution, and ADC sampling rate - the MSP430F2112TRTVR achieves 200 ksps ADC throughput at full speed.

Does the MSP430F2112TRTVR support in-system programming without external hardware?

Yes, the MSP430F2112TRTVR supports in-system programming via its built-in bootstrap loader (BSL), accessible through UART using P1.1 (TX) and P2.2 (RX) pins. No external programmer is required - firmware updates can be performed in the field using a simple serial interface and user-defined password protection. The MSP430F2112TRTVR also supports JTAG programming via Spy-Bi-Wire using RST/NMI/SBWTDIO and TEST/SBWTCK pins.

What analog features does the MSP430F2112TRTVR include beyond the ADC?

Beyond its 10-bit 200-ksps ADC10 with internal reference and DTC, the MSP430F2112TRTVR integrates Comparator_A+, which provides precision analog comparison, battery-voltage supervision, and slope analog-to-digital conversion. It supports programmable hysteresis, multiple reference sources (including internal VREF+/VREF−), and outputs usable as timer triggers or interrupt sources - enabling functions like threshold detection and RC-based A/D without external components.

Is the MSP430F2112TRTVR pin-compatible with other devices in the MSP430F21x2 family?

Yes, the MSP430F2112TRTVR shares identical pinout and package (32-pin QFN, RTV) with MSP430F2122TRTVR and MSP430F2132TRTVR. All three support the same peripheral mapping, GPIO assignments, and power/ground connections - allowing drop-in replacement where flash/RAM requirements permit. This enables scalable design across variants without PCB revision.

What development tools are recommended for the MSP430F2112TRTVR?

Texas Instruments recommends the MSP-FET430UIF (USB-based debugger) and MSP-FET430U28 (target board for 28-pin TSSOP) for evaluation and programming. For the 32-pin RTV package, a custom target board with Spy-Bi-Wire interface is required. Code development uses TI's MSP430Ware driver library and CCS IDE. The MSP430F2112TRTVR's integrated Emulation Module (EEM) supports real-time debugging, breakpoints, and register inspection without performance impact.
