Product details
Overview
MSP430F2111TDGV from Texas Instruments is an ultra-low-power 16-bit RISC 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 - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2111TDGV datasheet, MSP430F2111TDGV pinout, MSP430F2111TDGV application, or MSP430F2111TDGV equivalent, key selection criteria include its -40°C to 105°C extended temperature rating, TVSOP-20 package, 1.8–3.6 V supply range, sub-1 µs wake-up from standby, and integrated DCO with four factory-calibrated frequencies up to 16 MHz.
Technical Context
The MSP430F2111TDGV implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock module integrates a digitally controlled oscillator (DCO), 32-kHz crystal support, and high-frequency crystal input 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 and edge-selectable interrupts, plus a Comparator_A+ module supporting analog signal comparison and slope ADC functionality - all operating under five software-selectable low-power modes including LPM4 (0.1 µA RAM retention).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2112IDGV | Includes 10-bit SAR ADC (200 ksps), 16KB flash, same 20-pin TVSOP package - adds precision analog digitization capability. | Suitable where higher-resolution analog acquisition is required instead of slope ADC; not drop-in due to different peripheral register map. | Select when ADC performance outweighs cost sensitivity and existing firmware relies on comparator-based conversion. |
| MSP430G2553IPW28 | 28-pin TSSOP, 16KB flash, 512B RAM, built-in USB emulator, but rated only to 85°C - broader I/O count and debug integration. | Better suited for development-stage prototypes requiring USB debugging; larger footprint and lower temperature grade limit industrial deployment. | Prefer during evaluation or where USB connectivity and extra GPIO simplify bring-up - avoid for production in extended-temp environments. |

FAQ
What is the maximum operating frequency of the MSP430F2111TDGV?
The MSP430F2111TDGV supports a maximum system clock (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 supported frequency reduces to 6 MHz per TI's recommended operating conditions.
Does the MSP430F2111TDGV include a hardware ADC?
No, the MSP430F2111TDGV does not include a successive-approximation (SAR) or sigma-delta ADC. Instead, it integrates a Comparator_A+ module that supports slope analog-to-digital conversion using the 16-bit Timer_A - enabling effective 10–12 bit resolution with external RC network, as documented in SLAU144.
What package type and pin count does the MSP430F2111TDGV use?
The MSP430F2111TDGV uses a 20-pin Thin Very Small Outline Package (TVSOP), designated as DGV. It measures 4.4 mm × 6.5 mm with 0.65 mm lead pitch and includes an exposed thermal pad recommended to be connected to VSS for thermal and electrical stability.
Can the MSP430F2111TDGV be programmed without a JTAG debugger?
Yes, the MSP430F2111TDGV supports UART-based in-system programming via its integrated Bootstrap Loader (BSL), using P1.1 (TX) and P2.2 (RX) pins. A password-protected serial interface enables field firmware updates without requiring JTAG hardware - provided the BSL security key has not been disabled.
What is the operating temperature range for the 'T' version of the MSP430F2111TDGV?
The 'T' suffix in MSP430F2111TDGV indicates an extended industrial temperature grade of –40°C to +105°C. This rating is validated per TI's production test flow and supports reliable operation in demanding environments such as automotive under-hood sensors, industrial process controllers, and outdoor utility infrastructure.
