Product details

What this MSP430FR5727IDAR brings to the board

The 1 KB of SRAM handles stack and scratchpad for moderate workloads.

FRAM vs flash — why it matters for field updates and data logging

A flash MCU needs an erase cycle before rewriting even one byte; this part writes individual bytes directly.

38-TSSOP — fits a two-layer board without a stencil fight

The 38-TSSOP (6.10 mm body width) is a hand-solderable surface-mount package. 30 general-purpose I/O pins are available, leaving 8 pins for supply, ground, and oscillator.

Peripherals and connectivity for a sensor hub or control node

Active lifecycle — no LTB panic, fit for new designs

Frequently asked questions

Can MSP430FR5727IDAR be used as a replacement for MSP430FR5729?

The MSP430FR5729 is a higher-density sibling in the same family — it carries more FRAM and SRAM. The MSP430FR5727IDAR has 16 KB FRAM and 1 KB SRAM; the FR5729 typically doubles both. Pin-compatible in the same 38-TSSOP footprint, but check your memory budget before substituting downward.

What development tools support MSP430FR5727IDAR?

Standard MSP430 toolchain applies: TI's Code Composer Studio (CCS), IAR Embedded Workbench for MSP430, and the MSP430 LaunchPad development kits. The Spy-Bi-Wire (SBW) two-wire JTAG interface is used for programming and debug.
