MTFC32GAZAQHD-AAT

The MTFC32GAZAQHD-AAT is a 256 Gbit non-volatile FLASH NAND memory device with an integrated MMC controller, delivered in a 153-ball VFBGA (11.5 × 13 mm) package. It implements an e.MMC memory architecture with a managed NAND stack and supports JEDEC/MMC standard functionality for embedded storage in demanding environments.

Designed for automotive-grade applications, the device combines high-density storage with an advanced MMC interface, on-chip management features and functional-safety oriented options to address robust embedded storage requirements.

Key Features

• Integrated e.MMC solution — MMC controller combined with NAND flash for a managed, single-component storage solution.
• Memory capacity & organization — 256 Gbit capacity organized as 32G × 8, delivered in FLASH memory format.
• JEDEC/MMC compliance & interface — JEDEC/MMC Standard No. JESD84-B51-compliant with an advanced 12-signal interface and selectable ×1, ×4, and ×8 I/Os.
• High-speed operation — e.MMC interface clock frequency up to 200 MHz and boot frequency up to 52 MHz; supports HS200/HS400 modes.
• Power supply — VCC operating range 2.7 V to 3.6 V; VCCQ options include 1.70–1.95 V and 2.7–3.6 V.
• Automotive qualification & temperature — AEC-Q100 qualification and specified operating ambient temperature from −40°C to +105°C (TA).
• Reliability & data management — On-device ECC and block management, command queue, BKOPS control, auto/host-initiated refresh, reliable write and discard/sanitize capabilities.
• Security & safety features — Replay-protected memory block (RPMB), permanent and power-on write protection, temporary write protection, and field firmware update (FFU) support.
• Package — 153-ball VFBGA (11.5 × 13 mm) for compact board-level integration.

Typical Applications

• Automotive embedded storage — Use where automotive-grade e.MMC storage is required, leveraging AEC-Q100 qualification and extended temperature support.
• Embedded systems requiring managed NAND — Systems that need on-device ECC, block management and command queue features to simplify host software.
• High-speed MMC interfaces — Designs that require e.MMC connectivity up to 200 MHz and HS200/HS400 modes for faster data throughput.

Unique Advantages

• Integrated controller and NAND — Reduces BOM and integration complexity by providing a managed e.MMC device rather than discrete controller plus NAND.
• Standards-based interface — JEDEC/MMC v5.1 compliance simplifies host integration and ensures predictable interoperability.
• Automotive-grade qualification — AEC-Q100 qualification and extended operating temperature range support deployment in automotive environments.
• Robust data management — Built-in ECC, block management, BKOPS and refresh mechanisms improve data integrity and endurance management.
• Security and maintenance features — RPMB, write-protection options and field firmware update enable secure storage and in-field firmware management.
