Overview
MSP430FR6927IRGCT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, integrated LCD driver (up to 116 segments), 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 MSP430FR6927IRGCT datasheet, MSP430FR6927IRGCT pinout, MSP430FR6927IRGCT application, or MSP430FR6927IRGCT equivalent, key selection factors include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA), capacitive touch I/O support, AES256 encryption coprocessor, and VQFN-64 package compatibility with space-constrained designs.
Technical Context
The MSP430FR6927IRGCT implements the MSP430XV2 CPU core with unified FRAM memory space enabling simultaneous code execution and data storage without erase cycles. Its clock system integrates DCO, LFXT (32-kHz crystal), and VLO - but excludes HFXT, as confirmed for all MSP430FR692x devices.
Peripherals include dual eUSCI_A (UART/IrDA/SPI) and dual eUSCI_B (I²C/SPI) modules, three 16-bit Timer_A instances (TA0/TA1/TA2), one 16-bit Timer_B (TB0) with seven capture/compare registers, and an integrated LCD_C controller supporting static and 4-mux configurations - all operating within the same low-power domain architecture optimized for extended battery life.

FAQ
What is the maximum operating frequency of the MSP430FR6927IRGCT?
The MSP430FR6927IRGCT supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. This frequency applies to active-mode operation; lower frequencies are used in low-power modes such as LPM3 (VLO at ~10 kHz) or RTC domain (32-kHz LFXT). The device does not implement HFXT, so high-frequency crystal operation is not supported.
Does the MSP430FR6927IRGCT support hardware encryption?
Yes, the MSP430FR6927IRGCT includes a dedicated AES256 security coprocessor with support for both encryption and decryption operations. It also features a true random number seed generator to initialize cryptographic algorithms securely. These capabilities are implemented in hardware and operate independently of the CPU, enabling secure firmware updates and data-at-rest protection without compromising low-power performance.
What LCD configurations does the MSP430FR6927IRGCT support?
The MSP430FR6927IRGCT integrates the LCD_C peripheral supporting up to 116 segments in either static or 4-mux multiplexed configuration. It provides internal charge pump and contrast control, eliminating the need for external LCD bias circuitry. The device uses dedicated pins (P6.x, P2.x) for COM outputs and segment drivers, with segment mapping defined per package - specifically 116 segments for the RGC variant.
Is the MSP430FR6927IRGCT pin-compatible with other MSP430FR692x devices?
Yes, the MSP430FR6927IRGCT in the VQFN-64 (RGC) package shares identical pinout and electrical characteristics with MSP430FR69271IRGCT and MSP430FR6928IRGCT. All three devices use the same 64-pin RGC footprint, signal mapping, and thermal pad connection requirements, enabling direct substitution on existing PCBs without layout changes.
What is the typical current consumption of the MSP430FR6927IRGCT in RTC-only mode?
The MSP430FR6927IRGCT consumes 0.35 µA typical current in LPM3.5 mode, where only the real-time clock (RTC_C module) remains active with 32-kHz LFXT clock source. This value is measured under recommended operating conditions (3.0 V supply, 25°C ambient) and enables multi-year battery operation in applications such as utility meters and environmental loggers.
