Product details
Overview
MSP430FR6822IRGCR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, integrated 12-bit ADC, 116-segment LCD driver, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered utility meters and portable sensing applications.
For engineers reviewing the MSP430FR6822IRGCR datasheet, MSP430FR6822IRGCR pinout, MSP430FR6822IRGCR application, or MSP430FR6822IRGCR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), RTC power in LPM3.5 (0.35 µA), capacitive touch I/O without external components, and absence of AES encryption-distinguishing it from MSP430FR69xx variants.
Technical Context
The MSP430FR6822IRGCR 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 clock system integrates DCO, VLO, and LFXT (32-kHz crystal) but excludes HFXT-confirmed by functional block diagram notes and device comparison tables.
Peripherals include three 16-bit Timer_A instances (3/3/2 capture/compare registers), one 16-bit Timer_B (2/5 registers), CRC16/CRC32 hardware, DMA controller (3 channels), and dual eUSCI_A/B modules-each supporting SPI up to 10 Mbps, with eUSCI_A handling UART/IrDA and eUSCI_B handling I²C/multi-slave addressing.
Key Specifications

FAQ
Does the MSP430FR6822IRGCR include AES encryption hardware?
No, the MSP430FR6822IRGCR does not implement AES encryption. Per the functional block diagram note and device comparison table, AES256 is excluded from all MSP430FR682x and MSP430FR682x1 devices. This distinguishes the MSP430FR6822IRGCR from MSP430FR69xx variants which include 128/256-bit AES coprocessors for secure firmware and data protection.
What is the maximum operating frequency of the MSP430FR6822IRGCR?
The MSP430FR6822IRGCR supports up to 16 MHz operation via its factory-trimmed DCO. The clock system also includes VLO (10 kHz), LFXT (32 kHz crystal), and optional external high-frequency sources-but HFXT is explicitly omitted per functional block diagram notes, confirming 16 MHz DCO as the highest usable frequency.
Which packages are available for the MSP430FR6822IRGCR?
The MSP430FR6822IRGCR is offered exclusively in the VQFN-64 (RGC) package (9 mm × 9 mm) with thermal pad. While the MSP430FR6822 family includes LQFP-64 (PM) and TSSOP-56 (DGG) variants, the "IRGCR" suffix specifically denotes the VQFN-RGC variant per TI's device nomenclature documentation.
Can the MSP430FR6822IRGCR drive a 116-segment LCD directly?
Yes, the MSP430FR6822IRGCR integrates the LCD_C peripheral supporting up to 116 segments in static or 2–4 multiplex configurations. It provides built-in contrast control, charge pump, and COM/SEG outputs-enabling direct connection to segmented LCD glass without external bias ICs or discrete components.
Is the MSP430FR6822IRGCR pin-compatible with the MSP430FR6922IRGCR?
No, the MSP430FR6822IRGCR is not pin-compatible with the MSP430FR6922IRGCR. Although both use VQFN-64 (RGC) packages, their pinouts differ: MSP430FR6922IRGCR includes HFXIN/HFXOUT pins (absent in MSP430FR6822IRGCR), and signal assignments for P1.6/P1.7 (BSL vs. TA0.1/TA0.2) and P3.x (eUSCI_B1 vs. TA3) are incompatible per TI's pin diagrams and multiplexing tables.
