Product details
Overview
MSP430FR2000IRLLT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in a 24-pin VQFN package, featuring 0.5KB FRAM, 512B RAM, 16-MHz DCO with FLL, eUSCI_A for UART/SPI, and Timer_B3 with three capture/compare registers - designed for battery-powered smoke detectors and door/window sensors.
For engineers reviewing the MSP430FR2000IRLLT datasheet, MSP430FR2000IRLLT pinout, MSP430FR2000IRLLT application, or MSP430FR2000IRLLT equivalent, key selection criteria include LPM3.5 current (1 µA), capacitive touch I/O capability across all 12 GPIOs, absence of ADC (confirmed for this variant), VQFN-24 thermal performance, and Spy-Bi-Wire debug interface compatibility.
Technical Context
This MCU implements a 16-bit RISC CPU with constant generator for code efficiency and integrates a digitally controlled oscillator (DCO) enabling wake-up from LPM4.5 to active mode in under 10 µs. Its power management module supports five low-power modes, including LPM3.5 (1 µA with RTC + VLO) and LPM4.5 (34 nA shutdown).
The device uses unified FRAM memory architecture with ECC, configurable write protection, and 1015 write-cycle endurance. All 12 GPIOs support capacitive touch sensing, and peripheral control is managed via register-mapped modules including eUSCI_A, Timer_B3, CRC16, and enhanced comparator with integrated 6-bit DAC reference.
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 nodes. |
| Max Clock Frequency | 16 MHz via DCO+FLL; provides sufficient throughput for sensor polling, UART comms, and real-time event handling. |
| Memory | 0.5 KB FRAM program/data storage + 512 B RAM; unified nonvolatile memory eliminates flash erase delays and supports frequent data logging. |
| LPM3.5 Current | 1 µA with VLO; enables multi-year operation on coin-cell batteries in always-on sensor applications like smoke detectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2100IRLL | 1 KB FRAM, 512 B RAM, retains same 12 GPIOs, eUSCI_A, Timer_B3, and LPM3.5 current - adds 2× FRAM capacity without changing footprint or power profile. | Supports larger firmware images and extended data buffers; suitable when future feature expansion or longer event history is required. | Select MSP430FR2100IRLL if firmware size exceeds 0.5 KB or if additional nonvolatile storage for configuration parameters is needed. |
| MSP430FR2000IPW16 | Same FRAM/RAM, identical peripherals and low-power specs, but in 16-pin TSSOP (5 mm × 4.4 mm) - larger footprint, higher thermal resistance, no NC pins. | Better suited for prototyping or manual assembly; less optimal for high-density consumer PCBs where 3×3 mm VQFN is preferred. | Choose MSP430FR2000IPW16 only for breadboard evaluation or when TSSOP handling is required; otherwise prefer IRLL for production miniaturization. |

FAQ
Does the MSP430FR2000IRLLT include an analog-to-digital converter (ADC)?
No, the MSP430FR2000IRLLT does not include an ADC. Per TI's SLASE78E datasheet Section 4 (Functional Block Diagram) and Table 6-1 (Device Comparison), the ADC is explicitly omitted from all MSP430FR2000 variants. The MSP430FR2000IRLLT retains the enhanced comparator (eCOMP0) with 6-bit DAC reference for analog threshold detection, but lacks the 10-bit, 8-channel ADC found in MSP430FR21xx family members.
What is the maximum operating frequency and clock source flexibility of the MSP430FR2000IRLLT?
The MSP430FR2000IRLLT supports up to 16 MHz operation using its on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). It also integrates multiple clock sources: 32-kHz REFO, 10-kHz VLO, 16-MHz MODOSC, and external 32.768-kHz crystal (LFXT) input. MCLK and SMCLK are fully programmable with prescalars (1–128 and 1/2/4/8 respectively), enabling precise trade-offs between performance and power across active and low-power modes.
How many GPIO pins does the MSP430FR2000IRLLT have, and what special functions do they support?
The MSP430FR2000IRLLT provides 12 general-purpose I/O pins (P1.0–P1.7, P2.0–P2.3) in its 24-pin VQFN package. All 12 support capacitive touch sensing, interrupt wake-up from LPM3.5 and LPM4.5, and configurable pullup/pulldown. Eight of these (P1.0–P1.3, P1.5–P1.7, P2.0–P2.1) are designated as interrupt-capable pins per Section 7.2 of the datasheet.
What debug interface does the MSP430FR2000IRLLT use, and how many pins are required?
The MSP430FR2000IRLLT uses the Spy-Bi-Wire (SBW) debug interface, requiring only two pins: SBWTCK (pin 8) and SBWTDIO (pin 11, shared with RST/NMI). This 2-pin interface replaces full JTAG, reducing PCB routing complexity and test fixture cost while maintaining full flash programming, breakpoint, and real-time variable inspection capability via TI's MSP-FET and Code Composer Studio.
Is the MSP430FR2000IRLLT pin-compatible with other devices in the MSP430FR2xxx family?
Yes, the MSP430FR2000IRLLT shares identical pinout and package (24-pin VQFN, RLL) with MSP430FR2100IRLL, MSP430FR2110IRLL, and MSP430FR2111IRLL. All four variants are mechanically and electrically pin-compatible, differing only in FRAM/RAM size and peripheral enablement (e.g., ADC presence). This allows hardware reuse across product tiers with firmware-only differentiation.
