Product details
Overview
MSP430F2111TDGVR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB+256B flash, 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 MSP430F2111TDGVR datasheet, MSP430F2111TDGVR pinout, MSP430F2111TDGVR application, or MSP430F2111TDGVR equivalent, key selection criteria include its -40°C to 105°C extended temperature rating, TSSOP-20 package, integrated DCO with four factory-calibrated frequencies (1/8/12/16 MHz), and JTAG + BSL programming support without external voltage.
Technical Context
The MSP430F2111TDGVR 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), 32-kHz crystal input (XIN/XOUT), and high-frequency crystal support up to 16 MHz - all configurable via BCSCTL registers.
It features two 8-bit I/O ports (P1/P2) with individually programmable pullup/pulldown resistors, edge-selectable interrupts, and peripheral mapping via P1SEL/P2SEL. The Comparator_A+ module provides eight-channel analog input multiplexing (CA0–CA7), CAOUT output, and direct integration with Timer_A for slope ADC functionality.

FAQ
What is the maximum operating frequency of the MSP430F2111TDGVR?
The MSP430F2111TDGVR supports a maximum MCLK frequency of 16 MHz when VCC ≥3.3 V and duty cycle is 50% ±10%. This is achieved using the factory-calibrated DCO or an external high-frequency crystal. At lower supply voltages (e.g., 2.2 V), the maximum reliable frequency drops to 6 MHz per TI's recommended operating conditions.
Does the MSP430F2111TDGVR include a hardware ADC?
No, the MSP430F2111TDGVR does not contain a dedicated analog-to-digital converter. Instead, it uses the on-chip Comparator_A+ module with Timer_A to implement slope A/D conversion - a software-configurable method achieving effective 10-bit resolution without additional silicon area or power overhead.
What programming interfaces are supported by the MSP430F2111TDGVR?
The MSP430F2111TDGVR supports JTAG via pins P1.4–P1.7 and TEST/RST/NMI, and UART-based bootstrap loader (BSL) using P1.1 (TXD) and P2.2 (RXD). Both methods require no external programming voltage - the device is programmed directly from VCC, simplifying production and field updates.
Is the MSP430F2111TDGVR pin-compatible with other MSP430F21x1 variants?
Yes, the MSP430F2111TDGVR shares identical pinout and electrical characteristics with all TSSOP-20 members of the MSP430F21x1 family (e.g., MSP430F2101TDGVR, MSP430F2121TDGVR), differing only in flash size, RAM, and factory calibration data - enabling drop-in replacement within the same package variant.
What is the purpose of the TEST pin on the MSP430F2111TDGVR?
The TEST pin on the MSP430F2111TDGVR activates the JTAG interface when driven high during power-up. It is internally connected to the JTAG fuse; blowing this fuse disables JTAG access permanently, providing hardware-level security against unauthorized firmware extraction or modification of the MSP430F2111TDGVR.
