Product details
Overview
MSP430FR2000IPW16R from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 16-pin TSSOP (PW16) package, featuring 0.5KB program FRAM, 512 bytes RAM, 12 GPIOs (all capacitive touch-capable), and integrated eUSCI_A for UART/SPI/IrDA. It operates from 1.8 V to 3.6 V and targets battery-powered sensing nodes such as smoke detectors and door sensors.
For engineers reviewing the MSP430FR2000IPW16R datasheet, MSP430FR2000IPW16R pinout, MSP430FR2000IPW16R application, or MSP430FR2000IPW16R equivalent, key selection criteria include its LPM3.5 current (1 µA with VLO), absence of ADC (unlike FR21xx variants), 16-MHz DCO with ±1% accuracy, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430FR2000IPW16R implements a 16-bit RISC CPU with constant generator and 16-bit registers, enabling high code efficiency. Its clock system integrates a 16-MHz digitally controlled oscillator (DCO) with FLL, on-chip 32-kHz REFO, 10-kHz VLO, and external LFXT support - all programmable via CS module registers.
Power management includes six low-power modes (LPM0–LPM4.5); LPM3.5 retains RTC counter and 32-byte backup memory at 1 µA using VLO, while LPM4.5 achieves 34 nA shutdown without SVS. All 12 I/Os support capacitive touch sensing and eight can wake from any LPM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generator; enables compact, efficient firmware for resource-constrained sensing applications. |
| Memory | 0.5KB FRAM program memory + 512B RAM; unified nonvolatile memory supports fast writes (no erase), 10¹⁵ write endurance, and ECC protection. |
| Supply Voltage | 1.8 V to 3.6 V; minimum voltage constrained by SVS thresholds - enables direct operation from single Li-ion or two alkaline cells. |
| Low-Power Mode Current | LPM3.5: 1 µA (VLO active); LPM4.5: 34 nA (SVS disabled); critical for multi-year battery life in intermittent-sensing devices. |
| Clock Sources | On-chip 16-MHz DCO (±1% at 25°C), 32-kHz REFO, 10-kHz VLO, and external 32-kHz crystal support; enables flexible timing without external oscillators. |
| Peripherals | eUSCI_A0 (UART/IrDA/SPI), Timer_B3 (3 CCRs), CRC16, RTC counter, enhanced comparator (eCOMP0), and 1.5-V internal reference - no ADC included. |
| I/O Capability | 12 general-purpose I/Os in PW16 package; all support capacitive touch sensing and eight are interrupt-capable for wake-from-LPM functionality. |
Pinout & Package
Package: 16-pin TSSOP (PW16), 5.0 mm × 4.4 mm body size, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0 / UCA0STE / SMCLK / C0 / A0 / Veref+ | Multi-function I/O / SPI slave select / system clock output / comparator input | Primary SPI interface pin; SMCLK output enables synchronous peripheral clocking; no ADC function on MSP430FR2000IPW16R. |
| P1.1 / UCA0CLK / ACLK / C1 / A1 | Multi-function I/O / SPI clock / auxiliary clock output / comparator input | Configurable as SPI clock or ACLK source; C1 input usable with eCOMP0; A1 not functional (ADC absent). |
| TEST / SBWTCK | Debug interface clock input | Enables Spy-Bi-Wire programming and debugging using TI MSP-FET or LaunchPad debuggers. |
| RST/NMI/SBWTDIO | Reset / non-maskable interrupt / debug data I/O | Shared pin for device reset, NMI trigger, and bidirectional SBW communication - requires external pull-up. |
| DVCC / DVSS | Power supply pair | Single 1.8–3.6 V digital/analog supply; requires 4.7–10 µF bulk + 0.1 µF ceramic decoupling per datasheet Section 10.1. |
| P2.7 / TB0CLK / XIN | Timer/oscillator input | Accepts external 32-kHz crystal (XIN) or timer clock input (TB0CLK); LFXT startup time impacts RTC initialization. |
| P1.7 / UCA0TXD / UCA0SIMO / TB0.2 / TDO / A7 | Multi-function I/O / UART transmit / SPI master out / timer output / JTAG output | Primary serial transmit path; TDO enables boundary-scan visibility; A7 not functional (no ADC). |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2100IPW16R | 1KB FRAM, 512B RAM, includes 8-channel 10-bit ADC (200 ksps), same 16-pin TSSOP package and pinout. | Supports analog sensor interfacing (e.g., thermistors, potentiometers) where MSP430FR2000IPW16R requires external ADC. | Select when analog signal acquisition is required; identical footprint allows layout reuse but adds ADC-related BOM cost. |
| MSP430G2553IPW16R | Flash-based (16KB), 512B RAM, 8-channel 10-bit ADC, USCI_A/B, but higher LPM3 current (0.8 µA vs 1 µA) and no FRAM endurance. | Better suited for designs needing larger code space or legacy toolchain compatibility; lacks FRAM's write-speed and endurance advantages. | Choose for cost-sensitive, high-volume production where flash endurance suffices and existing G2x firmware can be ported with minimal changes. |
Compared with MSP430FR2100IPW16R, the MSP430FR2000IPW16R trades ADC capability for lower cost and smaller memory footprint; versus MSP430G2553IPW16R, it offers superior write endurance and lower deep-sleep current but requires FRAM-aware toolchain updates.

FAQ
Does MSP430FR2000IPW16R include an analog-to-digital converter (ADC)?
No, the MSP430FR2000IPW16R does not include an ADC. Unlike the MSP430FR21xx family members, this variant omits the 8-channel 10-bit ADC entirely - confirmed in the Functional Block Diagram (Figure 4-1) and Device Comparison Table (Table 6-1). Designers requiring analog sensing must use external ADCs or select MSP430FR2100IPW16R instead.
What is the maximum operating frequency of MSP430FR2000IPW16R?
The MSP430FR2000IPW16R supports up to 16 MHz system clock via its on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). The ±1% accuracy specification applies at room temperature using the internal reference, and the DCO enables sub-10 µs wake-up from low-power modes to full-speed execution.
Which debug interface does MSP430FR2000IPW16R support?
The MSP430FR2000IPW16R supports the Spy-Bi-Wire (SBW) interface using pins TEST/SBWTCK (Pin 3) and RST/NMI/SBWTDIO (Pin 4). This 2-wire subset of JTAG enables full flash programming, real-time debugging, and boundary-scan testing - compatible with TI MSP-FET and LaunchPad development tools.
Can MSP430FR2000IPW16R operate from a single 1.8-V supply?
Yes, the MSP430FR2000IPW16R operates across 1.8 V to 3.6 V, making it compatible with single-cell lithium batteries and regulated 1.8-V rails. However, the minimum functional voltage is constrained by SVS (supply voltage supervisor) thresholds - see Section 8.3 of SLASE78E for exact SVS level dependencies.
How many I/O pins on MSP430FR2000IPW16R support capacitive touch sensing?
All 12 general-purpose I/O pins on the MSP430FR2000IPW16R support capacitive touch sensing, as explicitly stated in Section 1 Features and Section 7.2 Pin Attributes. No external components are required - the integrated capacitive touch IO capability is enabled via software configuration of port registers.
