Product details
Overview
MSP430FR6822IPMR 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 devices.
For engineers reviewing the MSP430FR6822IPMR datasheet, MSP430FR6822IPMR pinout, MSP430FR6822IPMR application, or MSP430FR6822IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA), 64-pin LQFP package compatibility, and absence of AES encryption-distinguishing it from MSP430FR69xx variants.
Technical Context
The MSP430FR6822IPMR 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 (TA0–TA2), one 16-bit Timer_B (TB0), 32-bit hardware multiplier, three-channel DMA, and capacitive touch I/O on all ports. The device lacks AES256 coprocessor and high-frequency crystal support-explicitly excluded in datasheet notes for FR682x family members.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR68221IPMR | I²C-based bootloader (BSL); identical FRAM, ADC, LCD, and peripheral set | Preferred where secure firmware updates via I²C are required instead of UART | Select when production programming uses I²C interface and UART pins are reserved for application use |
| MSP430FR6922IPMR | Includes AES256 encryption coprocessor and supports same peripherals and package | Required for applications needing secure firmware storage, encrypted communication, or IP protection | Choose when data confidentiality or regulatory compliance (e.g., DLMS/COSEM) mandates hardware crypto acceleration |

FAQ
Does MSP430FR6822IPMR support hardware AES encryption?
No, MSP430FR6822IPMR does not include the AES256 coprocessor. This feature is exclusive to the MSP430FR69xx series (e.g., MSP430FR6922IPMR). The MSP430FR6822IPMR datasheet explicitly states AES256 is not implemented in FR682x devices, making it unsuitable for applications requiring hardware-accelerated encryption.
What is the maximum operating frequency of MSP430FR6822IPMR?
The MSP430FR6822IPMR supports up to 16 MHz system clock via its factory-trimmed DCO oscillator. It also accepts external 32-kHz LFXT for RTC operation but lacks HFXT support-confirmed in the functional block diagram notes and device comparison tables.
Which package type is used by MSP430FR6822IPMR?
MSP430FR6822IPMR uses a 64-pin LQFP package (10 mm × 10 mm) with exposed pad not required-distinct from the VQFN RGC variant. This is verified in the Device Information table and pin diagrams for PM/RGC packages in the datasheet.
Can MSP430FR6822IPMR drive a 116-segment LCD directly?
Yes, MSP430FR6822IPMR integrates the LCD_C module supporting up to 116 segments in static, 2-, 3-, or 4-mux configurations with programmable contrast control-enabling direct connection to segment-based displays without external bias generators or controllers.
What bootloader interface does MSP430FR6822IPMR use?
MSP430FR6822IPMR uses a UART-based bootloader (BSL), with P2.0 and P2.1 assigned as BSL_TX and BSL_RX respectively. This is confirmed in Section 4.1 Pin Diagrams and Table 3-1 Device Comparison, which lists "no" for AES and "UART BSL" for this part number.
