Product details
Overview
MSP430FR69221IRGCR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, integrated 12-bit ADC with 8 external channels, 116-segment LCD driver, and dual eUSCI modules supporting UART, IrDA, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered utility meters and sensor management systems.
For engineers reviewing the MSP430FR69221IRGCR datasheet, MSP430FR69221IRGCR pinout, MSP430FR69221IRGCR application, or MSP430FR69221IRGCR equivalent, key selection criteria include LPM3.5 RTC current (0.35 µA), FRAM endurance (10¹⁵ write cycles), AES256 security coprocessor support, and VQFN-64 package compatibility with capacitive touch I/O on all pins.
Technical Context
The MSP430FR69221IRGCR 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 with 10 factory-trimmed frequencies, LFXT for 32-kHz crystal operation, and VLO for ultra-low-power standby - but excludes HFXT (no HFXIN/HFXOUT pins).
Peripherals include three 16-bit Timer_A instances (TA0–TA2 with 3/3/2 capture/compare registers), one 16-bit Timer_B (TB0 with 7 registers), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, and dual eUSCI_A/B modules - all mapped to a 64-pin VQFN package with full pin multiplexing and capacitive touch capability on every I/O.

FAQ
What is the maximum operating frequency of the MSP430FR69221IRGCR?
The MSP430FR69221IRGCR supports a maximum CPU clock frequency of 16 MHz using its digitally controlled oscillator (DCO) with 10 factory-trimmed frequency settings. This allows deterministic real-time execution while maintaining ultra-low-power operation across all active and low-power modes.
Does the MSP430FR69221IRGCR support high-frequency crystal oscillators (HFXT)?
No, the MSP430FR69221IRGCR does not implement HFXT circuitry - HFXIN and HFXOUT pins are not present. It supports only LFXT (32-kHz crystal via PJ.4/PJ.5) and internal sources (DCO, VLO), making it optimized for low-frequency timing and RTC applications rather than high-speed communication clocks.
How many capture/compare registers does the MSP430FR69221IRGCR's Timer_A provide?
The MSP430FR69221IRGCR includes three Timer_A modules: TA0 and TA1 each provide 3 capture/compare registers, and TA2 provides 2 - totaling 8 registers. These support PWM generation, input capture, and interval timing for motor control, sensor triggering, and display backlight modulation.
What LCD configuration does the MSP430FR69221IRGCR support?
The MSP430FR69221IRGCR integrates LCD_C supporting up to 116 segments in static, 2-mux, 3-mux, or 4-mux configurations. It includes dedicated COM0–COM3 pins and segment drive capability - enabling direct connection to alphanumeric or custom segment displays without external drivers.
Is the MSP430FR69221IRGCR pin-compatible with the MSP430FR6922IRGCR?
Yes, the MSP430FR69221IRGCR and MSP430FR6922IRGCR share identical VQFN-64 (RGC) packaging, pinout, and peripheral mapping. The only functional difference is the inclusion of the AES256 coprocessor in the '221 variant - all I/O, memory, clock, and analog resources remain electrically and physically compatible.
