Product details
Overview
MSP430FR6927IPM from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, integrated LCD driver (up to 116 segments, 4-mux), 12-bit ADC with 8 external inputs, and real-time clock with calendar. It operates from 1.8 V to 3.6 V and targets battery-powered utility metering and data logging applications.
For engineers reviewing the MSP430FR6927IPM datasheet, MSP430FR6927IPM pinout, MSP430FR6927IPM application, or MSP430FR6927IPM equivalent, key selection considerations include FRAM endurance (1015 writes), LPM3.5 RTC current (0.35 µA), capacitive touch I/O support on all ports P1–P10/PJ, AES256 security coprocessor, and absence of HFXT oscillator (LFXT-only clocking).
Technical Context
The MSP430FR6927IPM implements the MSP430 CPUXV2 core with 16 registers and executes instructions at up to 16 MHz using a factory-trimmed DCO or 32-kHz LFXT crystal. Its low-power architecture includes seven defined modes-LPM0 through LPM4.5-with LPM3.5 enabling RTC operation while retaining full FRAM retention and wake-on-port interrupt capability.
Peripherals are memory-mapped and managed via a unified bus logic layer supporting DMA transfers across eUSCI_A0/A1 (UART/IrDA/SPI), eUSCI_B0/B1 (I²C/SPI), three 16-bit Timer_A modules (TA0/TA1/TA2), one 16-bit Timer_B (TB0), CRC16/CRC32 engines, and an AES256 encryption coprocessor-all accessible without CPU intervention in active or low-power states.

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 |
|---|---|---|---|
| MSP430FR6928IPM | 96KB FRAM, same package and peripherals; no change in I/O count, LCD capacity, or power specs. | Higher FRAM density required for extended firmware features or larger encrypted data buffers. | Select when firmware image size exceeds 64KB or long-term unattended logging demands >100KB buffer space. |
| MSP430FR69271IPM | Identical FRAM/RAM/LCD/ADC specs; differs only in bootloader interface-uses I²C BSL instead of UART BSL. | Systems requiring I²C-based factory programming or field firmware updates over existing sensor bus infrastructure. | Choose when production programming infrastructure relies on I²C master control rather than UART host connection. |
Compared with MSP430FR6927IPM, the MSP430FR6928IPM offers greater nonvolatile storage headroom for complex algorithms, while the MSP430FR69271IPM retains identical functionality but shifts bootloader access to I²C-both require no PCB redesign but differ in programming workflow and memory scalability.

FAQ
What is the maximum operating frequency of the MSP430FR6927IPM?
The MSP430FR6927IPM supports a maximum CPU clock frequency of 16 MHz, achieved using the factory-trimmed DCO oscillator or an external 32-kHz LFXT crystal with digital frequency synthesis. This frequency is fully supported across the entire 1.8 V to 3.6 V supply range and enables deterministic real-time response for metering calculations and communication stacks in the MSP430FR6927IPM.
Does the MSP430FR6927IPM include hardware support for secure firmware updates?
Yes, the MSP430FR6927IPM integrates a dedicated AES256 encryption/decryption coprocessor with a true random number seed generator. This enables authenticated and encrypted firmware images to be verified and decrypted in hardware-reducing CPU load and ensuring secure over-the-air or wired updates without exposing keys in software execution on the MSP430FR6927IPM.
Can the MSP430FR6927IPM drive a segment LCD without external components?
Yes, the MSP430FR6927IPM includes the LCD_C peripheral capable of driving up to 116 segments in 4-mux configuration using internal charge pumps and programmable bias generation. No external capacitors, resistors, or voltage boosters are required-making it ideal for compact, low-BOM-cost designs like heat cost allocators where the MSP430FR6927IPM directly interfaces to the display glass.
What low-power modes are available on the MSP430FR6927IPM, and what is the lowest active current?
The MSP430FR6927IPM offers seven low-power modes (LPM0–LPM4.5). Active-mode current is approximately 100 µA/MHz at 3.3 V. The lowest active-retention mode is LPM4.5 (shutdown), drawing 0.02 µA typical-while LPM3.5 (RTC active) consumes 0.35 µA typical, retaining full FRAM content and enabling calendar-triggered wake-up in the MSP430FR6927IPM.
Is the MSP430FR6927IPM pin-compatible with other devices in the MSP430FR692x family?
Yes, the MSP430FR6927IPM in the 64-pin LQFP (PM) package shares identical pinout, electrical characteristics, and peripheral mapping with the MSP430FR6928IPM and MSP430FR69271IPM-enabling direct substitution in production without layout changes.
