Product details
Overview
MSP430FR2000IPW16 from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 16-pin TSSOP package, featuring 0.5KB FRAM, 512B RAM, 12 GPIOs (all capacitive touch capable), eUSCI_A UART/SPI interface, and Timer_B3 with three capture/compare registers - designed for battery-powered smoke detectors and door/window sensors.
For engineers reviewing the MSP430FR2000IPW16 datasheet, MSP430FR2000IPW16 pinout, MSP430FR2000IPW16 application, or MSP430FR2000IPW16 equivalent, key selection criteria include LPM3.5 current (1 µA), 16-MHz DCO accuracy (±1% at room temperature), absence of ADC, and TSSOP-16 pin compatibility within the MSP430FR2x family.
Technical Context
This MCU implements a 16-bit RISC CPU with constant generator and digitally controlled oscillator (DCO) enabling sub-10 µs wake-up from LPM4.5. Its power management module supports five low-power modes including LPM3.5 (1 µA with VLO) and LPM4.5 (34 nA without SVS), optimized for intermittent sensing in energy-constrained systems.
The device integrates Spy-Bi-Wire debug interface, eUSCI_A supporting UART/IrDA/SPI, and a 16-bit RTC counter. All 12 I/O pins support capacitive touch sensing, and eight of them (P1.0–P1.3, P2.0–P2.3) serve as interrupt-capable wake sources from any LPM - critical for always-on sensor nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2100IPW16 | 1 KB FRAM, 512 B RAM, includes 8-channel 10-bit ADC - adds analog sensing capability absent in MSP430FR2000IPW16. | Required where ambient sensing (e.g., temperature, light) is needed alongside control logic. | Select when ADC integration justifies higher memory and $0.15–$0.20 BOM increase. |
| MSP430G2553IPW16 | Flash-based (16 KB), no FRAM, no VLO/LPM3.5, 23 µA active/MHz - lacks ultra-low-power sleep modes and nonvolatile write endurance. | Suitable for cost-driven, non-battery-critical applications where frequent firmware updates are unnecessary. | Choose only if legacy codebase compatibility outweighs 30× higher LPM3.5 current and flash wear limitations. |
Compared with MSP430FR2100IPW16, MSP430FR2000IPW16 trades ADC and memory for lowest cost and smallest FRAM footprint; versus MSP430G2553IPW16, it delivers 34× lower shutdown current and infinite FRAM write cycles - critical for field-deployed sensor nodes.

FAQ
Does MSP430FR2000IPW16 include an analog-to-digital converter (ADC)?
No, MSP430FR2000IPW16 does not include an ADC. The device datasheet explicitly states "The ADC is not available on the MSP430FR2000 device" across multiple sections including the functional block diagram and device comparison table. Analog sensing must be implemented externally or via the integrated enhanced comparator (eCOMP0) with its 6-bit DAC reference.
What is the maximum operating frequency of MSP430FR2000IPW16?
The MSP430FR2000IPW16 supports up to 16 MHz operation using its on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). At room temperature with the internal reference, the DCO achieves ±1% accuracy - sufficient for UART communication and real-time control without external crystal calibration.
Which low-power modes are supported by MSP430FR2000IPW16, and what are their typical currents?
MSP430FR2000IPW16 supports LPM3.5 (1 µA with VLO active) and LPM4.5 (34 nA without SVS). These modes retain RTC counter and 32-byte backup memory functionality while powering down the CPU and most peripherals - enabling multi-year operation on primary batteries in always-on sensor applications.
Is MSP430FR2000IPW16 pin-compatible with other devices in the MSP430FR2x family?
Yes, MSP430FR2000IPW16 shares identical pinout and package (TSSOP-16) with MSP430FR2100IPW16, MSP430FR2110IPW16, and MSP430FR2111IPW16. This allows hardware reuse across variants - for example, upgrading to MSP430FR2100IPW16 adds ADC capability without PCB redesign.
What debug interface does MSP430FR2000IPW16 use, and what pins are required?
MSP430FR2000IPW16 uses the two-wire Spy-Bi-Wire (SBW) interface, requiring only TEST/SBWTCK (Pin 3) and RST/NMI/SBWTDIO (Pin 4). This eliminates the need for full 4-pin JTAG headers, reducing PCB area and simplifying programming in space-constrained designs.
