Product details
Overview
MSP430F2111TDW from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 2KB+256B flash memory, 128B RAM, a 16-bit Timer_A with three capture/compare registers, and an on-chip analog comparator for slope A/D conversion. 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 MSP430F2111TDW datasheet, MSP430F2111TDW pinout, MSP430F2111TDW application, or MSP430F2111TDW equivalent, key selection criteria include its −40°C to +105°C extended temperature rating, 20-pin TSSOP (DW) package with JTAG/debug support, ultra-fast <1 μs wake-up from standby, and integrated brownout detection for robust operation in industrial sensing and energy-harvesting edge devices.
Technical Context
The MSP430F2111TDW implements a 16-bit RISC 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 external digital clock sources.
It features two 8-bit I/O ports (P1 and P2) with individually programmable pullup/pulldown resistors and edge-selectable interrupts, a 16-bit Timer_A3 with three capture/compare registers supporting PWM and interval timing, and Comparator_A+ with eight-channel input multiplexing (CA0–CA7) for analog signal monitoring and slope ADC functionality.

Does the MSP430F2111TDW include a hardware ADC?
No, the MSP430F2111TDW does not integrate a successive-approximation (SAR) or sigma-delta ADC. Instead, it provides Comparator_A+ with slope A/D conversion capability using Timer_A and the analog comparator - enabling low-resolution digitization of analog signals without external ADC components.
What debug interfaces are supported by the MSP430F2111TDW?
The MSP430F2111TDW supports full JTAG debugging via its dedicated TEST, TCK, TMS, TDI, and TDO pins mapped to Port 1 - enabled by the on-chip Embedded Emulation Module (EEM). It also supports Spy-Bi-Wire (2-wire JTAG) for space-constrained layouts, and the UART-based Bootstrap Loader (BSL) for firmware updates without debug hardware.
How much flash memory is available on the MSP430F2111TDW?
The MSP430F2111TDW contains 2 KB of main flash memory for program code and 256 B of information flash memory for calibration data, configuration storage, or bootloader code. The information memory is organized into four 64-byte segments (A–D), with Segment A pre-programmed with DCO calibration constants and protected after reset.
Is the MSP430F2111TDW pin-compatible with other MSP430F21x1 variants?
Yes, the MSP430F2111TDW shares identical pinout and package (20-pin TSSOP, DW) with all other MSP430F21x1 family members including MSP430F2101TDW, MSP430F2121TDW, and MSP430F2131TDW - enabling hardware reuse across memory-graded variants while maintaining identical PCB layout and peripheral routing.
