Product details

4 KB FRAM — no erase cycles, no wear-out worry

Its program memory is 4 KB of FRAM (ferroelectric RAM), which combines the non-volatility of Flash with the write speed and endurance of RAM — no erase cycles, no page boundaries, and retention rated for decades at temperature. The 1K x 8 RAM handles stack and scratchpad data. This makes it a strong fit for applications that log data frequently, update firmware over the air, or run on a coin cell where every microamp and every write cycle counts.

28-TSSOP — compact footprint for space-constrained boards

The 21 general-purpose I/O lines are enough for a keypad, a small character LCD, and a few sensor interrupts.

Frequently asked questions

Does MSP430FR5730IPW have an internal oscillator?

Yes, the MSP430FR5730IPW includes an internal oscillator. An external crystal is not required for basic operation, though the device also supports external clock sources if tighter timing accuracy is needed.

Is MSP430FR5730IPW RoHS compliant?

The MSP430FR5730IPW is a lead-free, RoHS-compliant device as shipped by Texas Instruments. The 28-TSSOP package uses a matte-tin finish compatible with standard reflow profiles.
