Product details
Overview
MSP430F2111TRGET from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 2KB flash, 128B RAM, a 16-bit Timer_A with three capture/compare registers, an on-chip analog comparator for slope A/D conversion, and integrated brownout detection. It operates from 1.8 V to 3.6 V and supports active-mode current of 250 μA at 1 MHz/2.2 V - optimized for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2111TRGET datasheet, MSP430F2111TRGET pinout, MSP430F2111TRGET application, or MSP430F2111TRGET equivalent, key selection criteria include its -40°C to 105°C extended temperature rating, TSSOP-20 package, ultra-fast <1 μs wake-up from standby mode, and built-in bootstrap loader for UART-based in-system programming without external voltage.
Technical Context
The MSP430F2111TRGET implements a 16-bit CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at 1/8/12/16 MHz, plus support for 32-kHz crystal and high-frequency external sources.
It features two 8-bit I/O ports (P1 and P2) with individually programmable pullup/pulldown resistors, edge-selectable interrupts, and JTAG-compatible test pins (TCK/TMS/TDI/TDO). The Comparator_A+ module accepts eight analog inputs (CA0–CA7) and delivers slope ADC capability or battery-supervision functions without external components.

FAQ
What is the maximum operating frequency of the MSP430F2111TRGET?
The MSP430F2111TRGET supports a maximum MCLK frequency of 16 MHz when VCC ≥3.3 V, with factory-calibrated DCO settings at 1/8/12/16 MHz. At 2.7 V, the guaranteed maximum is 12 MHz, and at 1.8 V it is 6 MHz - all specified under recommended operating conditions with 50% ±10% duty cycle. This ensures deterministic timing for real-time control loops and sensor sampling in the MSP430F2111TRGET.
Does the MSP430F2111TRGET support in-system programming without a JTAG debugger?
Yes, the MSP430F2111TRGET includes a factory-programmed bootstrap loader (BSL) that enables flash programming via UART using P1.1 (TX) and P2.2 (RX). No external programming voltage is required, and the BSL is protected by a user-defined password. This allows field firmware updates on deployed MSP430F2111TRGET devices without physical access to JTAG headers or specialized programmers.
What analog inputs does the Comparator_A+ module support on the MSP430F2111TRGET?
The MSP430F2111TRGET's Comparator_A+ module supports eight analog inputs: CA0 through CA7, mapped to P2.3, P2.4, P2.0, P2.1, P2.2, P2.5, P2.6, and P2.7 respectively. These inputs enable slope analog-to-digital conversion, battery-voltage supervision, and external signal monitoring - all without external components. The CAOUT pin provides comparator output directly usable by Timer_A for timing-critical conversions.
Is the MSP430F2111TRGET pin-compatible with other devices in the MSP430F21x1 family?
Yes, the MSP430F2111TRGET shares identical pinout and package (TSSOP-20) with all other MSP430F21x1 variants including MSP430F2101TRGET, MSP430F2121TRGET, and MSP430F2131TRGET. Firmware written for one can run on another with only flash/RAM size adjustments - enabling scalable design reuse across 1KB to 8KB memory requirements while maintaining identical board layout and peripheral routing for the MSP430F2111TRGET.
What development tools are recommended for the MSP430F2111TRGET?
Texas Instruments recommends the MSP-FET430UIF USB-based debugger and programmer, the MSP-TS430PW28 target socket board for TSSOP-20 devices, and the MSP-GANG430 gang programmer for high-volume production. All tools fully support the MSP430F2111TRGET's JTAG interface and on-chip emulation module, enabling real-time debugging, flash programming, and boundary-scan testing during both development and manufacturing of the MSP430F2111TRGET.
