Product details

FRAM-based 16-bit MCU for low-power sensing and control

The MSP430FR5727IRHAR: It carries 16 KB of FRAM program memory and 1K x 8 of RAM, with 32 general-purpose I/O lines.

We source MSP430FR5727IRHAR through our independent distribution network — each unit is verified against the manufacturer's specifications before shipment.

40-VQFN package — footprint and thermal notes

The MSP430FR5727IRHAR is supplied in a 40-VFQFN exposed-pad package (6x6 mm body, supplier device package 40-VQFN). The 32 I/O pins include multiplexed functions for the serial interfaces and PWM outputs.

Frequently asked questions

What is the replacement for MSP430FR5727IRHAR?

Texas Instruments has not published an official direct replacement order code for this part. The MSP430FR57xx family includes active variants in the same 40-VQFN package with similar FRAM and peripheral sets; check the MSP430FR5726 or higher-density siblings for pin-compatible options. For a confirmed alternate, submit an RFQ and we can cross-reference against available inventory.

Where can I buy MSP430FR5727IRHAR?

Submit an RFQ for current availability and pricing — each quote is confirmed at order time against verified stock.

Is MSP430FR5727IRHAR equivalent to MSP430FR5726?

Both are MSP430FR57xx family devices in the same 40-VQFN package, but the FR5726 offers a different memory configuration. Without a direct cross-reference from TI, treat them as separate BOM items. Verify pin compatibility from the respective datasheets before substitution.
