Product details
Overview
MSP430FR5720IPWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 4KB FRAM nonvolatile memory, 1KB RAM, and integrated peripherals including a 10-bit ADC (6 external channels), 10-channel analog comparator, three eUSCI modules (two UART/SPI-capable, one I²C/SPI-capable), five 16-bit timers, RTC, and hardware multiplier - designed for battery-powered sensor management and data acquisition in industrial and building automation systems.
For engineers reviewing the MSP430FR5720IPWR datasheet, MSP430FR5720IPWR pinout, MSP430FR5720IPWR application, or MSP430FR5720IPWR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), ultra-low standby current (6.3 µA in LPM3), 24-pin VQFN package footprint, and compatibility with TI's MSP-FET430U40A debug interface and Code Composer Studio™ IDE.
Technical Context
The MSP430FR5720IPWR implements the MSP430 CPUXV2 core with 16-bit RISC architecture, operating up to 8 MHz across a 2.0–3.6-V supply range. Its FRAM memory subsystem includes built-in ECC and MPU, enabling reliable code/data storage without wear leveling. The device supports seven low-power modes, with LPM3.5 delivering 1.5 µA RTC operation using a 32-kHz crystal.
Peripherals are tightly coupled via three-channel DMA and clocked by a flexible system clock tree with DCO, VLO, LFXT, and HFXT sources. The eUSCI_A0/A1 modules support UART with auto-baud detection and IrDA, while eUSCI_B0 provides I²C with multi-slave addressing and SPI - all configurable independently without CPU intervention.
