Product details
Overview
MSP430FR69221IRGCT from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, integrated 12-bit ADC with 8 external channels, 116-segment LCD driver, and AES-256 encryption coprocessor. It operates from 1.8 V to 3.6 V and supports real-time clock (RTC) with calendar/alarm in LPM3.5 mode (0.35 µA typical), targeting battery-powered utility meters and portable medical devices.
For engineers reviewing the MSP430FR69221IRGCT datasheet, MSP430FR69221IRGCT pinout, MSP430FR69221IRGCT application, or MSP430FR69221IRGCT equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), capacitive touch I/O without external components, dual eUSCI modules (UART/IrDA/SPI + I²C/SPI), and LFX-only clock system (no HFXIN/HFOUT).
Technical Context
The MSP430FR69221IRGCT implements the CPUXV2 core with 16 registers and integrates a 32-bit hardware multiplier, three-channel DMA, and CRC16/CRC32 engines. Its clock system relies exclusively on DCO and LFXT (32-kHz crystal); HFXT is not implemented per device-specific note.
It features five 16-bit timers (TA0–TA3, TB0) with capture/compare capability, RTC_C with calendar mode, and LCD_C supporting static and 2–4 multiplex configurations. The AES-256 coprocessor is enabled (confirmed for FR69xx family), and all I/O pins support capacitive touch sensing natively.

FAQ
What is the maximum operating frequency of the MSP430FR69221IRGCT?
The MSP430FR69221IRGCT supports a maximum CPU clock frequency of 16 MHz using its factory-trimmed DCO oscillator. It does not support high-frequency crystal (HFXT) operation - its clock system is limited to DCO and LFXT (32 kHz) sources, as confirmed in the functional block diagram notes and device comparison tables.
Does the MSP430FR69221IRGCT include hardware AES encryption?
Yes, the MSP430FR69221IRGCT includes a dedicated 128/256-bit AES security coprocessor, explicitly enabled for the MSP430FR69xx family per Section 1.1 Features and Figure 1-1. This distinguishes it from the non-"1" variant (MSP430FR6922IRGCT), which omits AES hardware.
What package type and dimensions does the MSP430FR69221IRGCT use?
The MSP430FR69221IRGCT uses a 64-pin VQFN (RGC) package measuring 9 mm × 9 mm with an exposed thermal pad. Texas Instruments recommends connecting the thermal pad to DVSS for optimal thermal performance and electrical stability, as stated in the pin diagrams section.
How many I/O pins support capacitive touch sensing on the MSP430FR69221IRGCT?
All general-purpose I/O pins on the MSP430FR69221IRGCT support capacitive touch sensing without external components. This capability is inherent to the port architecture and is documented in Section 1.1 Features under "Multifunction Input/Output Ports", enabling robust touch HMI in space-constrained designs.
What is the FRAM endurance rating for the MSP430FR69221IRGCT?
The MSP430FR69221IRGCT features 64KB of FRAM rated for 10¹⁵ write cycles - orders of magnitude higher than flash-based MCUs. This endurance allows continuous data logging (e.g., hourly meter readings) over decades without memory wear-out concerns, as specified in the Features section.
