25 MHz core — what it means for the control loop
25 MHz clock on the 16-bit pipeline delivers roughly 25 MIPS. Enough for real-time sensor polling, PID loops, and USB packet handling.
Lifecycle — obsolete, last-time-buy closed
The MSP430F5528IZQE is officially obsolete per the manufacturer's product status. The last-time-buy window has passed; TI no longer accepts orders through the authorized channel. Sourcing this part now means the independent surplus and broker market — date-code consistency, package integrity, and traceability back to a known-good lot are the authentication markers to verify. The laser etch on the BGA package is a fingerprint: check that the font, spacing, and plant-code match TI's standard for the marked week. We source and quote this part to order against an RFQ, with availability and current pricing confirmed at quote time through our verified broker network.
Peripherals and I/O — what is on-chip
12-bit ADC with 12 channels, brown-out detect/reset, DMA, POR, PWM, watchdog timer. 47 general-purpose I/O pins multiplexed with serial peripherals.
