Product details
Overview
MSP430F2101IDGV from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 1 KB Flash, 128 B RAM, a 16-bit Timer_A with three capture/compare registers, an on-chip analog comparator for slope A/D conversion, and brownout detection. It operates from 1.8 V to 3.6 V and supports active-mode current of 250 μA at 1 MHz/2.2 V - ideal for battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2101IDGV datasheet, MSP430F2101IDGV pinout, MSP430F2101IDGV application, or MSP430F2101IDGV equivalent, key selection considerations include its 20-pin TVSOP (DGV) package, calibrated DCO frequencies up to 16 MHz, ultra-fast <1 μs wake-up from standby mode, and integrated JTAG/emulation support for low-overhead development.
Technical Context
The MSP430F2101IDGV 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 and P2) with individually programmable pullup/pulldown resistors, edge-selectable interrupts, and shared functionality including Timer_A signals (TA0–TA2), comparator inputs (CA0–CA7), and JTAG test pins (TCK/TMS/TDI/TDO). The comparator_A+ module enables analog signal monitoring and slope-based A/D conversion without external components.

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 |
|---|---|---|---|
| MSP430F2111IDGV | 2 KB Flash, same RAM and peripherals - adds 1 KB program storage for larger firmware or calibration tables | Preferred where firmware complexity exceeds 1 KB or future feature expansion is required | Select when additional Flash headroom is needed without changing PCB layout or power profile |
| MSP430G2231IPW20 | Same 1 KB Flash/128 B RAM but newer G-series with enhanced BSL, lower active current (220 μA @ 1 MHz), and improved ESD rating | Better suited for new designs targeting higher reliability or longer battery life in harsh environments | Choose for new designs prioritizing modern process node benefits; not drop-in due to different pin mapping |
Compared with MSP430F2111IDGV, the MSP430F2101IDGV trades Flash capacity for cost-sensitive deployment; versus MSP430G2231IPW20, it offers legacy toolchain compatibility and proven field reliability but lacks newer low-power optimizations and pinout flexibility.

FAQ
What is the maximum operating frequency of the MSP430F2101IDGV?
The MSP430F2101IDGV supports a maximum system clock (MCLK) frequency of 16 MHz when powered at ≥3.3 V, enabled by its factory-calibrated DCO. At 2.7 V, the maximum is 12 MHz, and at 1.8 V, it is limited to 6 MHz per TI's recommended operating conditions. This scalability allows designers to balance performance and power consumption based on supply constraints.
Does the MSP430F2101IDGV support in-system programming without external hardware?
Yes, the MSP430F2101IDGV includes a UART-based bootstrap loader (BSL) that enables in-system programming via P1.1 (TXD) and P2.2 (RXD) using only a serial interface. No JTAG debugger is required for firmware updates, provided the BSL is enabled and protected by a user-defined password stored in information memory.
What package type does the MSP430F2101IDGV use, and what are its key mechanical dimensions?
The MSP430F2101IDGV uses a 20-pin Thin Shrink Small-Outline Package (TVSOP), designated by the DGV suffix. Its body measures 4.4 mm × 6.5 mm with 0.65 mm lead pitch and a maximum height of 1.2 mm - optimized for compact PCB layouts in space-constrained portable devices.
How does the analog comparator in the MSP430F2101IDGV enable slope A/D conversion?
The MSP430F2101IDGV's Comparator_A+ module compares an input voltage against a ramp generated by Timer_A's CCR0 output. When the comparator output toggles, Timer_A captures the count value - directly yielding a digital representation proportional to the input voltage. This eliminates external ADC components while maintaining 10–12 bit effective resolution depending on ramp linearity.
Is the MSP430F2101IDGV pin-compatible with other members of the MSP430F21x1 family?
Yes, the MSP430F2101IDGV shares identical pinout and package (20-pin TVSOP) with MSP430F2111IDGV, MSP430F2121IDGV, and MSP430F2131IDGV. Firmware and hardware designs can scale Flash capacity across these variants without PCB revision - provided software accounts for memory map differences and peripheral enable states.
