Product details
Overview
MSP430FR6822IG56R from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in a 56-pin TSSOP package, featuring 64KB FRAM, 2KB RAM, 12-bit ADC with 8 external channels, integrated 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 sensor nodes.
For engineers reviewing the MSP430FR6822IG56R datasheet, MSP430FR6822IG56R pinout, MSP430FR6822IG56R application, or MSP430FR6822IG56R equivalent, key selection criteria include LPM3.5 RTC current (0.35 µA), FRAM endurance (1015 writes), absence of AES256, lack of HFXT support, and TSSOP-56 package compatibility with capacitive touch I/O on all pins.
Technical Context
The MSP430FR6822IG56R implements a CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active) and LPM4.5 (shutdown at 0.04 µA). Its clock system relies solely on DCO and LFXT-no HFXT-making it suitable for cost-sensitive, crystal-restricted designs requiring precise 32-kHz timing.
Peripherals include three 16-bit Timer_A instances (3/3/2 capture/compare registers), one 16-bit Timer_B (2/5 registers), dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI), and an LCD_C module supporting static and 2–4 mux configurations up to 116 segments. AES256 is explicitly omitted per device family documentation.

FAQ
What is the maximum operating frequency of the MSP430FR6822IG56R?
The MSP430FR6822IG56R supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. This frequency is achievable across the full 1.8 V to 3.6 V supply range and enables deterministic real-time performance for metrology and control tasks without requiring external high-frequency crystals.
Does the MSP430FR6822IG56R support hardware AES encryption?
No, the MSP430FR6822IG56R does not include an AES256 coprocessor. Per TI's official documentation, AES is implemented only in the MSP430FR69xx series-not in the FR682x or FR687x families. For cryptographic requirements, consider the pin-compatible MSP430FR6922IG56R, which adds 128/256-bit AES acceleration.
What package type and dimensions does the MSP430FR6822IG56R use?
The MSP430FR6822IG56R uses a 56-pin TSSOP (DGG) package measuring 6.1 mm × 14 mm with standard 0.5-mm lead pitch. It has no exposed thermal pad, distinguishing it from QFN variants. This package is compatible with automated SMT assembly and supports high-density layouts in compact metering modules.
Can the MSP430FR6822IG56R drive a 116-segment LCD display?
Yes, the MSP430FR6822IG56R integrates the LCD_C peripheral capable of driving up to 116 segments in static mode or up to 100 segments in 2–4 multiplex configurations. Its dedicated COM0–COM3 pins and segment outputs eliminate the need for external LCD drivers, reducing system cost and component count in utility and thermostat displays.
What are the low-power mode current specifications for the MSP430FR6822IG56R?
The MSP430FR6822IG56R achieves 0.35 µA typical current in LPM3.5 (RTC active), 0.4 µA in LPM3 (VLO active), and 0.04 µA in LPM4.5 (full shutdown). These values are measured at 3 V and 25°C per TI's SLASE23E datasheet, enabling multi-year battery life in applications like heat cost allocators and portable sensors.
