Product details
Overview
MSP430FR2033IPMR from Texas Instruments is a 16-bit RISC mixed-signal microcontroller featuring 15.5 KB FRAM (15 KB program + 512 B info), 2 KB RAM, 10-channel 10-bit ADC, dual eUSCI modules (UART/I²C/SPI), and ultra-low-power operation down to 15 nA in LPM4.5 - deployed in smoke detectors, industrial sensor nodes, and capacitive-touch HMI controllers.
For engineers reviewing the MSP430FR2033IPMR datasheet, MSP430FR2033IPMR pinout, MSP430FR2033IPMR application, or MSP430FR2033IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ cycles), real-time clock support in LPM3.5 (0.77 µA), capacitive-touch I/O capability across all pins, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430FR2033IPMR integrates a 16-MHz DCO with FLL for precise clock generation, supports dual 16-bit Timer_A3 modules each with three capture/compare registers (CCR0–CCR2), and features a unified memory architecture where FRAM serves as program storage, constant table, and data logging space without separate EEPROM or Flash sectors.
Its power management includes SVS monitoring, programmable MCLK/SMCLK prescalers, and five low-power modes - LPM3.5 enables RTC operation with VLO or 32.768-kHz crystal while maintaining 0.4 µA or 0.77 µA current draw - all managed via dedicated PMM registers and interrupt-wake capability on P1/P2 pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and constant generators; enables high code efficiency and sub-10 µs wake-from-LPM active transition. |

Pinout & Package
LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad; requires standard 4.7–10 µF DVCC bypass and 0.1 µF decoupling per supply pair.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2032IPMR | 8 KB program FRAM + 512 B info FRAM + 1 KB RAM; identical peripherals and pinout but reduced memory capacity. | Suitable for simpler sensor nodes or cost-sensitive designs where 15 KB FRAM is unnecessary. | Select when application firmware fits within 8 KB and no long-term data logging is required. |
| MSP430FR2355TPMR | 16 KB FRAM + 2 KB RAM + enhanced analog (12-bit ADC, op-amps, DAC); 64-pin TQFP; higher active current (150 µA/MHz). | Better suited for closed-loop control or analog signal conditioning where precision and integration outweigh ultra-low-power needs. | Choose when design requires analog front-end expansion beyond 10-bit ADC or needs integrated op-amps/DAC. |
Compared with MSP430FR2032IPMR, the MSP430FR2033IPMR delivers 7 KB more FRAM for firmware growth and data logging; versus MSP430FR2355TPMR, it trades analog richness for lower active current and proven deployment in battery-critical endpoints.

FAQ
What is the maximum operating frequency of the MSP430FR2033IPMR?
The MSP430FR2033IPMR features a digitally controlled oscillator (DCO) with frequency-locked loop (FLL) that supports up to 16 MHz operation. This maximum frequency is achievable across the full recommended supply range (1.8 V to 3.6 V) and ambient temperature range (–40°C to 85°C), with ±1% accuracy at room temperature using the on-chip reference.
Does the MSP430FR2033IPMR support hardware real-time clock functionality?
Yes, the MSP430FR2033IPMR includes a dedicated 16-bit RTC counter that operates in LPM3.5 mode using either the internal VLO (10 kHz) or an external 32.768-kHz crystal connected to P4.1/XIN and P4.2/XOUT. In crystal mode, RTC consumes only 0.77 µA, enabling accurate timekeeping during ultra-low-power sleep.
How many pins on the MSP430FR2033IPMR support capacitive touch sensing?
All 60 general-purpose I/O pins on the MSP430FR2033IPMR support capacitive touch sensing via the integrated CapTIvate™-compatible CTS module. No external components are required, and touch functionality can be enabled on any combination of pins - including those shared with ADC, timers, or communication peripherals - through software configuration.
What debug interface does the MSP430FR2033IPMR use, and what pins are required?
The MSP430FR2033IPMR uses the two-wire Spy-Bi-Wire (SBW) interface for programming and debugging. It requires only two pins: RST/NMI/SBWTDIO (bidirectional data) and TEST/SBWTCK (clock input). These pins are shared with reset and test functions, so proper pull-up/pull-down biasing is required during normal operation to avoid interference.
Is the FRAM memory on the MSP430FR2033IPMR protected against unintended writes?
Yes, the MSP430FR2033IPMR includes configurable FRAM write protection via the MPASSWD register and segment-level lock bits. Protection can be applied to individual 128-byte segments or entire memory blocks, and is enforced by hardware - preventing accidental overwrites during firmware execution or field updates unless explicitly unlocked by authorized code.
