Product details
Overview
MSP430FR68221IPMR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, and integrated LCD driver supporting up to 116 segments. It features a DCO-based clock system with LFXT support (32-kHz crystal), five 16-bit timers, 12-bit ADC with 8 external channels, and dual eUSCI modules for UART/IrDA/SPI and I²C. Used in utility meters and portable medical devices requiring long battery life and reliable data retention.
For engineers reviewing the MSP430FR68221IPMR datasheet, MSP430FR68221IPMR pinout, MSP430FR68221IPMR application, or MSP430FR68221IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA typical), 64-pin LQFP package compatibility, and absence of AES256 encryption-distinguishing it from MSP430FR69xx variants.
Technical Context
The MSP430FR68221IPMR implements the CPUXV2 core with 16 general-purpose registers and operates at up to 16 MHz. Its clock system excludes HFXT support (no HFXIN/HFXOUT pins), relying solely on DCO and LFXT (LFXIN/LFXOUT) for timing-confirmed by device-specific functional block diagram notes and pinout validation.
It integrates three-channel DMA, CRC16/CRC32 hardware accelerators, and capacitive touch I/O on all ports without external components. The device lacks AES256 security coprocessor per datasheet note, and Timer_A TA3 is restricted to internal capture/compare only in PM/RGC packages-verified against Table 3-1 and Section 4.1 pin diagrams.

FAQ
What is the maximum operating frequency of the MSP430FR68221IPMR?
The MSP430FR68221IPMR operates at up to 16 MHz using its factory-trimmed DCO oscillator. It does not support high-frequency crystal (HFXT) inputs-HFXIN/HFXOUT pins are unimplemented per functional block diagram notes-so system timing relies on DCO or 32-kHz LFXT for low-power modes.
Does the MSP430FR68221IPMR include hardware AES encryption?
No, the MSP430FR68221IPMR does not implement the AES256 security coprocessor. This feature is explicitly excluded from MSP430FR682x and MSP430FR682x1 devices per datasheet Section 1.4 Functional Block Diagram note, distinguishing it from MSP430FR69xx variants.
What LCD configurations does the MSP430FR68221IPMR support?
The MSP430FR68221IPMR integrates the LCD_C module supporting up to 116 segments in static, 2-, 3-, or 4-mux configurations. It provides dedicated COM0–COM3 pins and segment outputs across multiple ports, with programmable contrast control and charge pump support for direct glass drive.
Which communication interfaces are available on the MSP430FR68221IPMR?
The MSP430FR68221IPMR includes two eUSCI_A modules (UART/IrDA/SPI up to 10 Mbps) and two eUSCI_B modules (I²C with multi-slave addressing and SPI up to 10 Mbps). It supports I²C bootloader (BSL) but not UART BSL-unlike MSP430FR69221IPMR which offers UART BSL instead.
What is the standby current consumption of the MSP430FR68221IPMR in LPM3 mode?
In LPM3 mode with VLO clock source, the MSP430FR68221IPMR consumes 0.4 µA typical. When RTC is enabled (LPM3.5), current rises to 0.35 µA typical-leveraging the 32-kHz crystal for calendar/timekeeping while maintaining ultra-low power.
