16 MHz speed — timing budget for sensor polling
The 16 MHz core clock defines the cycle budget for low-power sensor polling and simple control loops. With 2 KB Flash and 128 B RAM, firmware is limited to tight state machines or calibration-table lookups — no room for complex protocol stacks or over-the-air updates. The internal oscillator keeps BOM count low for single-board designs.
Lifecycle and sourcing — EOL hot, last-time-buy window closing
The MSP430F2011TRSAT carries an EOL hot lifecycle status, meaning the manufacturer's last-time-buy window is active but closing. This part is sourced through independent distribution on a quoted-to-order basis against an RFQ. Availability and current pricing are confirmed at quote time. No official pin-compatible successor is listed; for dual-sourcing or long-term production, evaluate the broader MSP430F2xx family for a density or package variant that fits the same footprint.
