Product details
Overview
MSP430FR58721IRGCR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 64KB nonvolatile FRAM, 2KB RAM, 16-MHz DCO clock, integrated 12-bit ADC with 8 external channels, RTC with calendar mode, and dual eUSCI modules supporting UART/IrDA/SPI (eUSCI_A) and I²C/SPI (eUSCI_B). It targets battery-powered sensor nodes and data loggers requiring long-term memory retention without write endurance limits.
For engineers reviewing the MSP430FR58721IRGCR datasheet, MSP430FR58721IRGCR pinout, MSP430FR58721IRGCR application, or MSP430FR58721IRGCR equivalent, key selection criteria include its 0.35 µA RTC-active LPM3.5 current, 1015 FRAM write-cycle endurance, 51 GPIOs in 64-pin VQFN, absence of AES256 encryption, and UART-based BSL support - all critical for energy-harvested IoT edge devices.
Technical Context
The MSP430FR58721IRGCR implements the MSP430 CPUXV2 core with seven low-power modes, including LPM3.5 (RTC active at 0.35 µA) and LPM4.5 (shutdown at 0.04 µA), enabled by SVS brownout protection and flexible clock sources (DCO, LFXT, HFXT). Its FRAM architecture unifies program, data, and storage space with 125 ns word-write speed and no erase-before-write requirement.
Peripherals include three 16-bit timers (TA0–TA3, TB0), 32-bit hardware multiplier, three-channel DMA, CRC16/CRC32 engines, capacitive touch I/O on all pins, and analog comparator with up to 16 inputs. The device lacks AES256 security coprocessor - confirmed in functional block diagram notes - distinguishing it from MSP430FR59xx variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit CPUXV2 RISC core, up to 16-MHz operation - enables deterministic real-time control with low gate count and minimal power overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR59721IRGCR | Includes AES256 encryption coprocessor and identical FRAM/RAM/peripheral set; same 64-pin VQFN package. | Required where secure firmware updates or encrypted sensor data storage are mandated (e.g., medical, payment systems). | Select MSP430FR59721IRGCR when cryptographic acceleration is needed; otherwise, MSP430FR58721IRGCR offers cost and power advantage. |
| MSP430FR5872IPMR | Same core specs and peripherals, but in 64-pin LQFP (10 mm × 10 mm) instead of VQFN (9 mm × 9 mm); higher thermal resistance. | Suitable for prototyping or applications requiring through-hole rework or legacy PCB footprints. | Choose MSP430FR5872IPMR for manual assembly or thermal margin tolerance; MSP430FR58721IRGCR preferred for space-constrained, high-volume SMT designs. |
Compared with MSP430FR59721IRGCR, the MSP430FR58721IRGCR omits AES256 but retains identical power profile and FRAM performance - making it optimal for cost-sensitive, non-secure sensing. Against MSP430FR5872IPMR, it delivers identical functionality in a smaller, thermally superior VQFN package.

FAQ
What is the maximum operating frequency of the MSP430FR58721IRGCR?
The MSP430FR58721IRGCR supports a maximum CPU clock frequency of 16 MHz via its factory-trimmed DCO or external HFXT crystal. This frequency is fully operational across the specified voltage range (1.8 V to 3.6 V) and enables real-time processing of sensor data while maintaining sub-100 µA/MHz active-mode current efficiency.
Does the MSP430FR58721IRGCR include hardware AES encryption?
No, the MSP430FR58721IRGCR does not include AES256 encryption hardware. As explicitly noted in the functional block diagram section of the datasheet, AES256 is implemented only in MSP430FR59xx(1) devices. The MSP430FR58721IRGCR retains all other peripherals - including FRAM, RTC, ADC, and eUSCI - but omits the security coprocessor.
What package type and dimensions does the MSP430FR58721IRGCR use?
The MSP430FR58721IRGCR uses a 64-pin VQFN package (RGC suffix), with a 9 mm × 9 mm body size and exposed thermal pad. TI recommends connecting the thermal pad to DVSS for optimal thermal performance and electrical stability in continuous operation.
How many I/O pins does the MSP430FR58721IRGCR provide, and what special capabilities do they offer?
The MSP430FR58721IRGCR provides 51 general-purpose I/O pins. Every I/O pin supports capacitive touch sensing without external components, and all support programmable pullup/pulldown, edge-selectable interrupts, and bit/byte/word access - enabling flexible interface design for sensors, displays, and communication peripherals.
What is the typical current consumption of the MSP430FR58721IRGCR in RTC-active low-power mode?
In LPM3.5 mode with RTC running from a 32-kHz crystal, the MSP430FR58721IRGCR consumes 0.35 µA typical current. This value is measured under standard conditions (3 V supply, 25°C) and enables multi-year operation on a single CR2032 coin cell when paired with infrequent sensor reads and minimal wake-up duration.
