Product details

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.

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.

Frequently asked questions

Is MSP430F5528IZQE obsolete?

Yes, the MSP430F5528IZQE is obsolete. The last-time-buy window has closed, so new orders go through the independent surplus and broker channel. We source and quote it to order against an RFQ.

What is the replacement for MSP430F5528IZQE?

No official direct replacement is listed in the manufacturer's documentation. For a pin-compatible alternative, check the MSP430F5528IPN (64-pin QFP) or the MSP430F5638IZQE (same BGA footprint, 18 KB RAM) — but verify the peripheral set and memory map against your firmware before committing the BOM. We can help cross-reference on request.

What is the datasheet for MSP430F5528IZQE?

The datasheet is available from Texas Instruments under the base product number MSP430F5528. It covers the full family electrical characteristics, pinout diagrams for the 80-BGA, and application notes for USB and low-power operation.

What is the pinout of MSP430F5528IZQE?

The pinout is defined in the TI datasheet for the 80-BGA MICROSTAR JUNIOR package. The 47 I/O and power balls are arranged in a 10x10 grid with a 0.5 mm pitch; the USB D+/D- are on dedicated balls, not shared with GPIO.

What is MSP430F5528IZQE's listed speed?

The core processor runs at 25 MHz with the MSP430 CPUXV2 16-bit pipeline, delivering approximately 25 MIPS.
