MTFC16GAPALBH-AAT: Micron 16GB Automotive eMMC Selection and Sourcing Guide

Micron 16GB automotive eMMC design and sourcing review

MTFC16GAPALBH-AAT is a Micron 16GB automotive e.MMC managed-NAND device, not an EEPROM or raw NAND part. The cited Micron family documentation identifies this exact MPN as a 153-ball TFBGA package measuring 11.5 mm × 13 mm × 1.1 mm, with the AAT option listed from –40°C to +105°C. It must be reviewed with the host e.MMC controller, boot design, rails, PCB layout, manufacturing process and lifecycle controls as one system.

For a BOM decision, first verify the complete MPN, package, controlled datasheet revision and lifecycle status. DigiKey currently lists the exact item as obsolete; current availability, price, lead time, traceability and alternate suitability require quote-time and manufacturer verification.

What this part is—and what it is not

Micron’s automotive e.MMC documentation describes a MultiMediaCard controller combined with NAND flash. It lists functions such as error correction and block management, boot operation, RPMB, multiple partitions, reliable write, background operations, health reporting and field firmware update at the family level.

Family capability does not guarantee application readiness. The target SoC, operating system or boot firmware must support the needed e.MMC behavior, and the controlled datasheet and software plan must define the final implementation.

Selection boundary: an alternate must be reviewed for package, ball map, e.MMC revision, power rails, boot behavior, software-visible geometry, temperature range and qualification needs. Do not call it a drop-in replacement before that review.
eMMC host controller connection and selectable data bus architecture
Host-controller support, bus configuration and firmware are part of the component decision.

Interface, voltage and performance checks

The cited Micron family documentation states JEDEC MMC 5.1 compliance, a 12-signal interface, host-selectable x1/x4/x8 I/O widths, interface clocks up to 200 MHz, HS200/HS400 modes, VCC from 2.7V to 3.6V and dual VCCQ options of 1.70V to 1.95V or 2.7V to 3.6V.

These are integration inputs—not blanket system-performance promises. The family performance table is measured at 25°C with x8 I/O, sequential 512KB chunks, write cache enabled, queue depth eight and HS400 mode. For the 16GB density it reports typical 60 MB/s sequential write and 320 MB/s sequential read under those conditions. Validate the real host, layout, rails, workload and temperature.

Package and PCB design review

  1. Confirm the approved land pattern from controlled manufacturer documentation.
  2. Validate breakout, stack-up, via technology and signal-return paths with the board fabricator.
  3. Review VCC/VCCQ decoupling, reset behavior and power-up sequencing with the host.
  4. Define reflow, X-ray/inspection and traceability requirements in the manufacturing release.
  5. Confirm the target e.MMC I/O width and mode in both PCB routing and firmware.

Automotive temperature and data-retention context

The AAT option is listed in the cited family datasheet for –40°C to +105°C. The documentation also lists automotive-grade information including AEC-Q104 and PPAP at family level, plus specified retention compliance conditions.

Do not turn a family-level statement into automatic design approval. Automotive design-in requires the exact qualification evidence, customer requirements, environmental profile, system validation and change-control records.

Why lifecycle status changes the procurement workflow

DigiKey currently labels MTFC16GAPALBH-AAT as obsolete. That does not prove that supply is unavailable, and it does not identify a valid alternate. It means the RFQ needs greater control.

RFQ itemWhy it is needed
Complete MPN and suffixPrevents an incorrect density, package, temperature or option code.
Quantity and delivery dateRequired for a current quote and supply assessment.
Date-code and traceability ruleDefines acceptable material for a controlled legacy purchase.
Packaging requirementConfirms handling and assembly expectations.
Test and quality-document needsLets the supplier state what can be verified.
Approved-alternative rulesKeeps a parametric option separate from a validated replacement.

Frequently asked questions

What is MTFC16GAPALBH-AAT?

It is a Micron 16GB automotive e.MMC managed-NAND device. The cited family datasheet lists it in a 153-ball TFBGA, 11.5 mm × 13 mm × 1.1 mm configuration.

Is MTFC16GAPALBH-AAT an EEPROM?

No. It is an e.MMC managed-NAND storage device with an MMC controller, not an EEPROM.

What does AAT mean on this part?

The cited Micron family documentation lists AAT for the –40°C to +105°C option. Confirm controlled documentation and project qualification before approval.

Can another 16GB e.MMC replace it?

Not automatically. Review package, ball map, rails, e.MMC version, boot behavior, software, temperature and qualification. Equal density alone is not compatibility.
