Product details
Overview
MSP430FR2100IPW16 from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 16-pin TSSOP (PW16) package, featuring 1KB program FRAM, 512-byte RAM, 12 I/Os, and integrated eUSCI_A for UART/SPI, Timer_B3 with three capture/compare registers, and real-time clock counter - deployed in battery-powered smoke detectors and door/window sensors.
For engineers reviewing the MSP430FR2100IPW16 datasheet, MSP430FR2100IPW16 pinout, MSP430FR2100IPW16 application, or MSP430FR2100IPW16 equivalent, key selection criteria include LPM3.5 current (1 µA), 16-MHz DCO accuracy (±1% at room temperature), capacitive touch I/O support across all pins, and absence of ADC functionality - critical for cost-optimized sensing nodes where analog conversion is handled externally.
Technical Context
The MSP430FR2100IPW16 implements a 16-bit RISC CPU with constant generator and digitally controlled oscillator (DCO) enabling sub-10-µs wake-up from LPM modes. Its clock system integrates REFO (32 kHz), VLO (10 kHz), MODOSC, and external LFXT support - all programmable via CS module with MCLK prescaler (1–128) and SMCLK division (1/2/4/8).
Power management includes SVS with configurable thresholds, LPM4.5 shutdown (34 nA), and LPM3.5 RTC operation (1 µA with 32.768-kHz crystal). All 12 GPIOs are capacitive-touch-capable, and interrupt capability on eight pins (P1.0–P1.3, P2.0–P2.3) enables wake-from-sleep event detection without external circuitry.

FAQ
Does MSP430FR2100IPW16 include an analog-to-digital converter (ADC)?
No, the MSP430FR2100IPW16 does not include an ADC. Per TI's SLASE78E datasheet Section 6 Device Comparison and Figure 4-1, the ADC is explicitly omitted from the MSP430FR2100 and MSP430FR2000 variants. The MSP430FR2100IPW16 retains eCOMP0 (enhanced comparator) with 6-bit DAC reference and programmable hysteresis for threshold-based analog sensing, but lacks the 8-channel 10-bit ADC found in MSP430FR2110IPW16 and MSP430FR2111IPW16.
What is the maximum operating frequency of MSP430FR2100IPW16?
The MSP430FR2100IPW16 supports up to 16 MHz system clock via its digitally controlled oscillator (DCO), with ±1% accuracy at room temperature using the internal reference. This frequency is achievable across the full 1.8–3.6 V supply range and enables fast wake-up from low-power modes in under 10 µs - critical for responsive sensor polling and real-time communication tasks in the MSP430FR2100IPW16.
Which development tools support MSP430FR2100IPW16?
The MSP430FR2100IPW16 is supported by the MSP-TS430PW20 20-pin target board (socketed for PW16), MSP-FET430U20 programmer/debugger, and MSP-EXP430FR2311 LaunchPad development kit. TI's free MSP430Ware™ software - integrated into Code Composer Studio™ IDE - provides driver libraries, example code, and configuration tools specifically validated for the MSP430FR2100IPW16 and its FRAM memory architecture.
Can MSP430FR2100IPW16 operate from a single 1.8-V supply?
Yes, the MSP430FR2100IPW16 operates from 1.8 V to 3.6 V, with guaranteed functionality down to 1.8 V. However, minimum supply voltage is constrained by SVS (Supply Voltage Supervisor) thresholds - at 1.8 V, SVS must be disabled or configured to avoid unintended resets. The device maintains full peripheral operation including FRAM writes, eUSCI_A, and Timer_B3 at 1.8 V, making it suitable for direct single-cell Li-ion or two-cell alkaline battery use.
Is MSP430FR2100IPW16 pin-compatible with other devices in the FR21xx family?
Yes, the MSP430FR2100IPW16 is pin-compatible with MSP430FR2110IPW16, MSP430FR2111IPW16, and MSP430FR2000IPW16 in the 16-pin TSSOP (PW16) package. All share identical pin numbering, signal mapping, power domains (DVCC/DVSS), and peripheral pin assignments - enabling hardware reuse across memory variants. Firmware must be recompiled to match FRAM/RAM sizes and enabled peripherals (e.g., ADC is absent in MSP430FR2100IPW16).
