Product details
Overview
MSP430FR69271IRGCR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64KB FRAM, 2KB RAM, integrated LCD driver (116 segments, 4-mux), 12-bit ADC with 8 external inputs, RTC with calendar/alarm, and dual eUSCI modules supporting UART/IrDA/SPI/I²C. It operates from 1.8 V to 3.6 V and targets battery-powered metering applications.
For engineers reviewing the MSP430FR69271IRGCR datasheet, MSP430FR69271IRGCR pinout, MSP430FR69271IRGCR application, or MSP430FR69271IRGCR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 RTC current (0.35 µA), capacitive touch I/O support on all ports P1–P10/PJ, AES256 encryption coprocessor, and absence of HFXT oscillator (LFXT-only clock system).
Technical Context
The MSP430FR69271IRGCR implements the MSP430XV2 CPU core with 16 general-purpose registers and executes instructions in single-cycle mode at up to 16 MHz. Its clock system relies exclusively on DCO and LFXT (32-kHz crystal) - HFXT is not implemented, per datasheet Note in Figure 1-2.
It integrates three Timer_A modules (TA0/TA1/TA3), one Timer_B (TB0), 3-channel DMA, CRC16/CRC32 hardware accelerators, and an LCD_C peripheral configured for static or 4-mux operation driving up to 116 segments. The device supports I²C Bootloader (BSL) via P1.6 (BSLSDA) and P1.7 (BSLSCL).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| FRAM Capacity | 64 KB nonvolatile memory with 10¹⁵ write endurance and 125 ns/word write speed - enables frequent data logging without wear-out concerns. |
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct connection to single Li-ion or two alkaline cells without external regulation. |
| LPM3.5 Current | 0.35 µA typical with RTC active - extends battery life to >10 years in metering applications with daily wake-up. |
| ADC Resolution | 12-bit SAR with internal reference and sample-and-hold - delivers ±1 LSB INL for precision sensor interfacing. |
| LCD Drive Capability | Up to 116 segments with 4-mux support - drives standard utility meter displays without external segment drivers. |
| Clock Sources | DCO (10 factory-trimmed frequencies), VLO, and LFXT only - no HFXT; simplifies BOM by eliminating high-frequency crystal and load capacitors. |
| AES Engine | Hardware-accelerated 128/256-bit AES encryption/decryption - secures firmware updates and meter data transmission. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR6927IRGC | Identical FRAM/RAM/LCD/ADC specs; differs only in BSL type - UART instead of I²C. | Requires UART interface for firmware updates; unsuitable where only I²C bus is available in end equipment. | Select MSP430FR6927IRGC if UART-based programming and debugging infrastructure is already deployed. |
| MSP430FR6928IPM | 96KB FRAM (vs. 64KB), same 64-pin LQFP package, identical peripherals and low-power modes. | Higher FRAM capacity supports extended logging duration or larger firmware images; requires same PCB footprint. | Choose MSP430FR6928IPM when future firmware growth or longer data retention is anticipated without layout change. |
Compared with MSP430FR6927IRGC, the MSP430FR69271IRGCR provides I²C BSL for secure, 2-wire field updates; compared with MSP430FR6928IPM, it trades FRAM capacity for cost-sensitive metering where 64KB suffices for 10+ year logs.

FAQ
What is the maximum operating frequency of the MSP430FR69271IRGCR?
The MSP430FR69271IRGCR supports a maximum system clock frequency of 16 MHz using the internally trimmed DCO oscillator. It does not implement the HFXT oscillator, so external high-frequency crystals are not supported. The device relies on DCO and LFXT (32.768 kHz) for all timing sources, with DCO factory-trimmed at 10 selectable frequencies ranging from 1 MHz to 16 MHz.
Does the MSP430FR69271IRGCR support hardware AES encryption?
Yes, the MSP430FR69271IRGCR includes a dedicated hardware AES256 encryption and decryption coprocessor. This module supports both 128-bit and 256-bit keys and operates independently of the CPU, enabling secure firmware updates and encrypted data storage in FRAM without compromising real-time performance or power efficiency.
What LCD configuration does the MSP430FR69271IRGCR support?
The MSP430FR69271IRGCR integrates the LCD_C peripheral configured for up to 116 segments with 4-mux capability. It supports static, 2-mux, 3-mux, and 4-mux drive schemes and provides dedicated COM0–COM7 outputs. The device does not support the full 320-segment capability found in higher-tier MSP430FR697x devices, aligning with its targeted use in compact utility meters.
How many GPIO pins does the MSP430FR69271IRGCR provide?
The MSP430FR69271IRGCR offers 52 general-purpose I/O pins across ports P1–P10 and PJ. All GPIOs support capacitive touch sensing without external components, and most support multiple peripheral functions including ADC inputs, timer capture/compare, USCI signals, and LCD segment driving - enabling highly integrated metering designs with minimal external circuitry.
What bootloading interface is implemented on the MSP430FR69271IRGCR?
The MSP430FR69271IRGCR implements an I²C-based hardware bootloader (BSL) accessible via P1.6 (BSLSDA) and P1.7 (BSLSCL). Unlike UART BSL variants, this configuration enables firmware updates over a standard 2-wire I²C bus - ideal for sealed, battery-operated meters where UART access is impractical and security against unauthorized reprogramming is required.
