Overview
MSP430F2111IDGVR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB 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, enabling battery-powered sensor node applications requiring long runtime and analog signal conditioning.
For engineers reviewing the MSP430F2111IDGVR datasheet, MSP430F2111IDGVR pinout, MSP430F2111IDGVR application, or MSP430F2111IDGVR equivalent, key selection criteria include its 20-pin TVSOP (DGV) package, calibrated DCO supporting 1–16 MHz operation without external crystal, brownout detection, and JTAG/on-chip emulation for debug and programming.
Technical Context
The MSP430F2111IDGVR implements a 16-bit RISC CPU with constant generators and seven addressing modes, achieving 62.5-ns instruction cycle time. 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 includes two 8-bit I/O ports (P1 and P2) with individually programmable pullup/pulldown resistors and edge-selectable interrupts, plus a Comparator_A+ module with eight-channel analog input multiplexing (CA0–CA7) and CAOUT output for slope ADC or voltage supervision.

FAQ
What is the maximum operating frequency of the MSP430F2111IDGVR?
The MSP430F2111IDGVR supports a maximum system clock (MCLK) frequency of 16 MHz when VCC ≥ 3.3 V, enabled by its factory-calibrated digitally controlled oscillator (DCO). At lower supply voltages (e.g., 2.2 V), the maximum frequency is reduced to 6 MHz per TI's recommended operating conditions. This DCO-based clocking eliminates the need for external crystals in many applications while maintaining ±1% accuracy across calibrated frequencies.
Does the MSP430F2111IDGVR support in-system programming without external hardware?
Yes, the MSP430F2111IDGVR supports in-system programming via its onboard bootstrap loader (BSL), which operates over UART using P1.1 (TX) and P2.2 (RX). No external programmer is required - a simple TTL-level UART interface suffices. The BSL is protected by a user-defined password and can be disabled permanently using the security key at address 0xFFDE, ensuring firmware integrity in deployed systems.
How many analog inputs does the comparator module in the MSP430F2111IDGVR support?
The Comparator_A+ module in the MSP430F2111IDGVR supports eight analog inputs: CA0 through CA7. These are mapped to P2.3, P2.4, P2.5, P2.0, P2.1, P2.2, P2.6, and P2.7 respectively. All eight inputs are accessible simultaneously via software-controlled multiplexing, enabling flexible configurations such as window comparators, battery voltage monitoring, or slope analog-to-digital conversion without external components.
What low-power modes are available on the MSP430F2111IDGVR, and what is the lowest current draw?
The MSP430F2111IDGVR offers six operating modes: Active Mode (AM) and five low-power modes (LPM0–LPM4). In LPM4 - where CPU, MCLK, SMCLK, ACLK, and DCO are all disabled - the device draws just 0.1 μA at 2.2 V while retaining RAM contents. This makes it ideal for applications requiring infrequent wake-up events, such as monthly environmental data uploads or tamper-triggered alerts in security systems.
Is the MSP430F2111IDGVR pin-compatible with other members of the MSP430F21x1 family?
Yes, the MSP430F2111IDGVR is pin-compatible with all 20-pin variants in the MSP430F21x1 family, including MSP430F2101IDGVR, MSP430F2121IDGVR, and MSP430F2131IDGVR. They share identical TVSOP-20 (DGV) pinouts, register maps, and peripheral configurations - differing only in flash size (1KB–8KB), RAM (128B–256B), and factory calibration data. This allows seamless migration between variants without PCB redesign.
