Product details
Overview
MSP430FR69221IPMR 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 (UART/IrDA/SPI + I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered metering and sensing applications requiring RTC calendar, capacitive touch I/O, and AES-256 encryption.
For engineers reviewing the MSP430FR69221IPMR datasheet, MSP430FR69221IPMR pinout, MSP430FR69221IPMR application, or MSP430FR69221IPMR equivalent, key selection criteria include LPM3.5 RTC current (0.35 µA), FRAM endurance (10¹⁵ writes), AES coprocessor support, 64-pin LQFP package compatibility, and UART/I²C BSL configuration.
Technical Context
The MSP430FR69221IPMR 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 for FR692x(1) devices.
Peripherals include three 16-bit Timer_A instances (TA0/TA1/TA3), one 16-bit Timer_B (TB0), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32, and dual eUSCI_A/B modules supporting simultaneous UART/IrDA/SPI and I²C/SPI. AES-256 encryption is implemented and enabled-unlike FR682x/FR687x variants.

FAQ
What is the maximum operating frequency of the MSP430FR69221IPMR?
The MSP430FR69221IPMR supports a maximum CPU clock frequency of 16 MHz using its factory-trimmed DCO or external HFXT (though HFXT is not implemented in FR692x(1) devices per functional block diagram notes-so 16 MHz is achieved via DCO only). This enables high-speed signal processing while maintaining ultra-low active-mode current (~100 µA/MHz).
Does the MSP430FR69221IPMR support hardware AES encryption?
Yes, the MSP430FR69221IPMR includes a dedicated 128/256-bit AES security encryption and decryption coprocessor, confirmed in the "Features" section and explicitly noted as implemented (unlike MSP430FR682x/FR687x variants). This enables secure firmware updates and encrypted data storage in the MSP430FR69221IPMR's 64KB FRAM.
What package type and dimensions does the MSP430FR69221IPMR use?
The MSP430FR69221IPMR uses a 64-pin LQFP package measuring 10 mm × 10 mm with standard 0.5-mm pitch. Per TI's Device Information table, this is the "PM" package variant-pin-compatible with other MSP430FR692x(1) LQFP devices and suitable for automated SMT assembly.
How many I/O pins does the MSP430FR69221IPMR provide?
The MSP430FR69221IPMR provides 52 general-purpose I/O pins, as specified in Table 3-1 for MSP430FR6922 and confirmed across FR692x(1) variants. These include P1–P9, PJ, and specialized pins like LCD segments and COM lines-all configurable for capacitive touch, analog, or digital functions.
Is the MSP430FR69221IPMR compatible with the MSP430FR6922IPMR in terms of pinout and software?
Yes, the MSP430FR69221IPMR is pin-to-pin compatible with the MSP430FR6922IPMR and shares identical peripheral registers, memory map, and instruction set. The only functional difference is the presence of the AES-256 coprocessor in the MSP430FR69221IPMR-making it a drop-in upgrade for secure applications without requiring PCB or firmware changes.
