Its 16KB of program memory uses FRAM.
The MSP430FR5728IPW carries an EOL hot lifecycle status, meaning the manufacturer has announced end-of-life and a last-time-buy window is active. Buyers should place final orders promptly to lock in allocation.
The MSP430FR5728IPW carries an EOL hot lifecycle status, meaning the manufacturer has announced end-of-life and a last-time-buy window is open. It is not yet obsolete, but the window to order through franchised channels is closing. Sourcing through independent distribution is available against an RFQ.
It comes in a 28-TSSOP package (4.40 mm width, 0.65 mm pitch) with 21 usable I/O pins.
The supply range is 2V to 3.6V, allowing direct battery or 3.3V rail operation.
FRAM writes at bus speed with no erase cycle and offers near-infinite endurance (10^15 cycles), versus Flash's 10^4–10^5 cycle limit and slower write/erase. FRAM also consumes less power during writes, making it better for frequent data logging and field updates.
Not directly — the FRAM memory map and programming model differ from Flash-based MSP430F parts. Code written for an MSP430F will need porting to account for FRAM timing and the unified memory space. Pin-compatible FRAM siblings in the same 28-TSSOP package exist, but verify the peripheral set matches your application.
