Product details
Overview
MSP430FR6922IRGCT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC, LCD driver (up to 116 segments), and real-time clock with calendar. It operates from 1.8 V to 3.6 V and supports LPM3.5 mode at 0.35 µA for battery-powered metering and sensing applications.
For engineers reviewing the MSP430FR6922IRGCT datasheet, MSP430FR6922IRGCT pinout, MSP430FR6922IRGCT application, or MSP430FR6922IRGCT equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), AES-256 encryption support, capacitive touch I/O without external components, and RTC operation in LPM3.5 with 3.7-pF crystal.
Technical Context
The MSP430FR6922IRGCT implements a CPUXV2 core with 16 general-purpose registers and integrates three eUSCI modules (two UART/IrDA/SPI-capable eUSCI_A, one I²C/SPI eUSCI_B) plus a 32-bit hardware multiplier and three-channel DMA. Its clock system includes DCO with 10 factory-trimmed frequencies, LFXT for 32-kHz crystal support, and no HFXT - confirming absence of high-frequency crystal interface per device family documentation.
It features dual 16-bit Timer_A instances (TA0, TA1) with 3 capture/compare registers each, one 16-bit Timer_A (TA2) with internal-only I/O, and one 16-bit Timer_B (TB0) with 5 capture/compare registers. The RTC domain operates independently in LPM3.5, powered by VLO or external 32-kHz source, and drives calendar/alarm functions with dedicated low-power oscillator path.

FAQ
What is the maximum operating frequency of the MSP430FR6922IRGCT?
The MSP430FR6922IRGCT supports a maximum CPU clock frequency of 16 MHz, achieved via its digitally controlled oscillator (DCO) with 10 factory-trimmed frequency steps. This allows deterministic real-time execution while maintaining ultra-low active-mode current of ~100 µA/MHz - critical for responsive sensor fusion in portable medical devices using the MSP430FR6922IRGCT.
Does the MSP430FR6922IRGCT support hardware AES encryption?
Yes, the MSP430FR6922IRGCT includes a dedicated 128/256-bit AES security coprocessor compliant with FIPS PUB 197. It accelerates encryption/decryption operations for secure boot, firmware updates, and data-at-rest protection - a feature confirmed in the device family datasheet and enabled in MSP430FR69xx variants only, not in FR682x or FR687x series.
What package type is used for the MSP430FR6922IRGCT?
The MSP430FR6922IRGCT uses a 64-pin VQFN package (RGC), measuring 9 mm × 9 mm with 0.5-mm pitch and an exposed thermal pad. TI recommends connecting the thermal pad to DVSS for optimal thermal performance and EMI reduction - a requirement verified in the official mechanical drawings and package addendum for this exact part number.
Can the MSP430FR6922IRGCT drive a 4-mux LCD display?
Yes, the MSP430FR6922IRGCT integrates the LCD_C module supporting up to 116 segments in static, 2-, 3-, or 4-mux configurations. Its dedicated COM and SEG pins (e.g., P6.3/COM0, P6.4/COM1) and programmable bias control enable direct drive of 4-mux LCDs used in utility meters and thermostats - confirmed in the device-specific functional block diagram and LCD_C chapter of the datasheet.
What is the standby current consumption of the MSP430FR6922IRGCT in LPM3 mode?
The MSP430FR6922IRGCT consumes 0.4 µA typical in LPM3 mode (VLO active), as specified in Section 5.6 of the SLASE23E datasheet. This ultra-low quiescent current enables multi-year operation on primary batteries in applications such as heat cost allocators and portable sensors where the MSP430FR6922IRGCT serves as the sole system controller.
