Product details
Overview
MSP430F2111IDGV from Texas Instruments is an ultra-low-power 16-bit 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 and 2.2 V - ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2111IDGV datasheet, MSP430F2111IDGV pinout, MSP430F2111IDGV application, or MSP430F2111IDGV equivalent, key selection considerations include its 20-pin TVSOP (DGV) package, calibrated DCO frequencies up to 16 MHz, brownout detection, and integrated emulation module for JTAG-based debugging and programming.
Technical Context
The MSP430F2111IDGV implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock system 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 and P2) with individually programmable pullup/pulldown resistors, edge-selectable interrupts, and JTAG-compatible test pins (TCK/TMS/TDI/TDO). The Comparator_A+ module supports analog signal comparison and slope ADC functionality using up to eight inputs (CA0–CA7), with CAOUT routed to P2.2.

FAQ
What is the maximum operating frequency of the MSP430F2111IDGV?
The MSP430F2111IDGV supports a maximum system clock (MCLK) frequency of 16 MHz when VCC ≥ 3.3 V, enabled by its factory-calibrated DCO. At lower supply voltages (e.g., 2.2 V), the maximum reliable frequency drops to 6 MHz per TI's recommended operating conditions - ensuring timing compliance and flash programming stability.
Does the MSP430F2111IDGV support JTAG debugging?
Yes, the MSP430F2111IDGV includes a full JTAG interface with dedicated pins (TCK, TMS, TDI, TDO) mapped to P1.4, P1.5, P1.6, and P1.7. It also integrates an Embedded Emulation Module (EEM) that supports hardware breakpoints, real-time trace, and flash programming - compatible with TI's MSP-FET430UIF and third-party JTAG tools.
Can the MSP430F2111IDGV perform analog-to-digital conversion without an external ADC?
Yes, the MSP430F2111IDGV uses its Comparator_A+ module for slope analog-to-digital conversion. By charging a capacitor through a known current and comparing against the input voltage, it achieves effective ADC functionality using only internal resources - eliminating the need for external ADC components in low-resolution sensing applications.
What package type does the MSP430F2111IDGV use?
The MSP430F2111IDGV uses a 20-pin Thin Shrink Small-Outline Package (TVSOP), designated as DGV per TI's packaging nomenclature. It measures 4.4 mm × 6.5 mm with 0.65 mm lead pitch and is RoHS-compliant - optimized for high-density PCB layouts and reflow soldering processes.
Is the MSP430F2111IDGV suitable for automotive applications?
No, the MSP430F2111IDGV is rated for industrial temperature range (–40°C to 85°C) and is not qualified to AEC-Q100 standards. While it may operate in some non-safety-critical automotive environments, TI does not specify or guarantee performance under automotive qualification requirements - use MSP430FRxx or C2000™ devices for certified automotive designs.
