Product details
Overview
MSP430FR5970IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 32KB nonvolatile FRAM, 2KB RAM, 16-MHz CPU, integrated 12-bit ADC with 8 external channels, AES256 encryption coprocessor, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and metering systems requiring long-term data retention without wear-out.
For engineers reviewing the MSP430FR5970IPMR datasheet, MSP430FR5970IPMR pinout, MSP430FR5970IPMR application, or MSP430FR5970IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (0.35 µA), AES256 security support, 64-pin LQFP package compatibility, and UART/I²C dual-protocol flexibility in constrained power designs.
Technical Context
The MSP430FR5970IPMR implements a 16-bit CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA). Its FRAM architecture enables byte-level writes with no erase cycle, eliminating flash write latency and wear limitations.
Peripherals include two eUSCI_A modules (UART/IrDA/SPI up to 10 Mbps) and two eUSCI_B modules (I²C with multi-slave addressing and SPI), five 16-bit timers (TA0–TA3, TB0), 32-bit hardware multiplier, and CRC16/CRC32 engines - all accessible via three-channel DMA for autonomous operation in sleep modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| FRAM Capacity | 32 KB unified memory for code, data, and logging - enables instant write persistence without erase delay or wear leveling. |
| CPU Speed | Up to 16 MHz - supports real-time signal processing and fast wake-from-sleep response in sensor fusion applications. |
| LPM3.5 Current | 0.35 µA typical with RTC active - extends battery life to years in calendar-aware data loggers and time-stamped sensor nodes. |
| ADC Resolution | 12-bit with internal reference and sample-and-hold - delivers precise analog sensing for metering and environmental monitoring. |
| AES Engine | 256-bit hardware encryption/decryption - secures firmware updates and sensor data transmission without CPU overhead. |
| eUSCI Interfaces | 2 × eUSCI_A (UART/IrDA/SPI), 2 × eUSCI_B (I²C/SPI) - enables simultaneous wired communication with host MCU and peripheral sensors. |
| Supply Voltage | 1.8 V to 3.6 V - supports direct Li-ion/Li-SOCl₂ battery operation and eliminates need for external regulators in compact designs. |
Pinout & Package
LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad (recommended connection to DVSS). Pinout validated per TI SLASE66C Rev. August 2018, Figures 4-1 and Table 4-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0–P1.7 | General-purpose I/O with capacitive touch | Supports self-capacitive touch sensing without external components; configurable pullup/pulldown and edge-triggered wakeup. |
| P2.0–P2.3 | UART BSL interface + RTC clock input | P2.0/P2.1 serve as BSL_TX/BSL_RX; P2.2 provides RTCCLK output - enables field firmware updates and real-time timestamping. |
| P3.4–P3.7 | eUSCI_A1 (UART/SPI) primary interface | UCA1SIMO/UCA1SOMI/UCA1CLK/UCA1STE - dedicated full-duplex UART or master SPI channel for sensor hub communication. |
| PJ.4/PJ.5 | Low-frequency crystal oscillator terminals | Connect 32.768-kHz crystal for RTC accuracy ±20 ppm - critical for energy-harvested nodes requiring calendar-grade timekeeping. |
| DVCC1/DVCC2/DVCC3 | Digital supply pins (3x) | Independent power domains reduce noise coupling; each must be decoupled with 100 nF ceramic capacitor near respective pin. |
| AVCC1/AVSS1/AVSS2 | Analog supply and ground | Separate analog rail isolates ADC and comparator references from digital switching noise - improves ENOB by ≥1.5 bits. |
Key Features
| Feature | Design Value |

The MSP430FR5970IPMR features a 16-bit CPUXV2 core with a maximum clock frequency of 16 MHz. This speed is achievable using the integrated DCO or external HFXT crystal, and is fully supported across all voltage ranges (1.8 V to 3.6 V). The MSP430FR5970IPMR maintains timing compliance and low-power mode entry/exit integrity at this rate, making it suitable for real-time control loops and high-speed sensor sampling.
Does the MSP430FR5970IPMR support hardware AES encryption?
Yes, the MSP430FR5970IPMR includes a dedicated 128/256-bit AES security encryption and decryption coprocessor. This hardware engine operates independently of the CPU, supports DMA-accelerated data transfers, and is explicitly confirmed in the device feature list and functional block diagram of the MSP430FR5970IPMR datasheet (SLASE66C). It enables secure firmware updates and encrypted sensor data transmission without compromising real-time performance.
What package type and dimensions does the MSP430FR5970IPMR use?
The MSP430FR5970IPMR is offered exclusively in the LQFP-64 package (body size 10 mm × 10 mm, 0.5 mm pitch), as documented in TI's Package Option Addendum and confirmed in the device comparison table. This package includes an exposed thermal pad recommended for connection to DVSS to enhance thermal performance and stability under sustained FRAM write operations.
How much FRAM and RAM does the MSP430FR5970IPMR integrate?
The MSP430FR5970IPMR integrates 32 KB of unified ferroelectric RAM (FRAM) and 2 KB of volatile RAM. The FRAM serves as combined program memory, data memory, and data logging storage - eliminating partitioning constraints and enabling true byte-level writes with no erase cycle. The 2 KB RAM provides fast-access working memory for stack, heap, and real-time variables, fully compatible with standard C toolchains.
What low-power modes are available on the MSP430FR5970IPMR, and what is the lowest current draw?
The MSP430FR5970IPMR supports seven low-power modes (LPM0–LPM4.5), with LPM4.5 (shutdown mode) drawing just 0.04 µA typical. In LPM3.5 - where the RTC remains active - current is 0.35 µA typical. These values are measured at 3 V and 25°C per TI's SLASE66C specification tables and are guaranteed across the full operating temperature range, enabling multi-year battery life in always-on sensing applications.
