Product details
Overview
MSP430FR59221IPMR from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller with 64KB nonvolatile memory, 2KB RAM, 12-bit ADC, AES256 encryption coprocessor, and RTC clocked by 3.7-pF crystal. It operates from 1.8 V to 3.6 V and supports seven low-power modes including LPM3.5 (0.35 µA typical) for battery-powered sensor nodes.
For engineers reviewing the MSP430FR59221IPMR datasheet, MSP430FR59221IPMR pinout, MSP430FR59221IPMR application, or MSP430FR59221IPMR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), integrated capacitive touch I/O without external components, and dual eUSCI modules supporting UART/IrDA/SPI/I²C at up to 10 Mbps.
Technical Context
The MSP430FR59221IPMR implements a 16-bit CPUXV2 core with hardware multiplier and three-channel DMA, enabling efficient signal processing in energy-constrained systems. Its clock system integrates DCO with factory-trimmed frequencies, LFXT for RTC operation, and no HFXT support - distinguishing it from MSP430FR597x variants.
Peripherals include five 16-bit timers (TA0–TA3, TB0), CRC16/CRC32 accelerators, and ADC12_B with up to eight external analog inputs and internal reference. The device lacks HFXIN/HFXOUT pins and supports only LFXIN/LFXOUT for 32-kHz crystal connection, aligning with its focus on ultra-low-power timing applications.

FAQ
What is the maximum operating frequency of the MSP430FR59221IPMR?
The MSP430FR59221IPMR supports a maximum system clock frequency of 16 MHz using its digitally controlled oscillator (DCO). This frequency is factory-trimmed across 10 selectable settings and can be further calibrated using the built-in reference. The device does not support external high-frequency crystals (HFXT), so all timing above 32 kHz relies on the DCO or VLO sources.
Does the MSP430FR59221IPMR support hardware AES encryption?
Yes, the MSP430FR59221IPMR includes a dedicated 128/256-bit AES security coprocessor that performs encryption and decryption independently of the CPU. This enables secure firmware updates, encrypted communication, and protected key storage without impacting real-time application performance. The MSP430FR5922IPMR variant lacks this feature.
What crystal specifications are required for the RTC on the MSP430FR59221IPMR?
The MSP430FR59221IPMR RTC requires a 32.768-kHz tuning-fork crystal with load capacitance of 3.7 pF, as specified in the datasheet. The device uses PJ.4 (LFXIN) and PJ.5 (LFXOUT) exclusively for this low-frequency crystal; no high-frequency crystal support is provided. External loading capacitors are not needed due to internal capacitance calibration.
How many I/O pins on the MSP430FR59221IPMR support capacitive touch sensing?
All general-purpose I/O pins on the MSP430FR59221IPMR - including ports P1 through P9 and PJ - support capacitive touch sensing via the integrated CapTIvate™-compatible CSD module. No external components are required, and touch functionality is enabled per-pin through software configuration of the port registers and comparator settings.
What low-power modes are available on the MSP430FR59221IPMR and their typical current draw?
The MSP430FR59221IPMR offers seven low-power modes: LPM0–LPM4 and LPM3.5/LPM4.5. Typical current draws are Active Mode (~100 µA/MHz), LPM3 with VLO (0.4 µA), LPM3.5 with RTC active (0.35 µA), and LPM4.5 shutdown (0.04 µA). These values assume DVCC = 3.0 V and room temperature, with all peripherals disabled except those explicitly enabled in each mode.
