MTFC64GASAQHD-AAT

The MTFC64GASAQHD-AAT is a 512 Gbit non-volatile e.MMC storage device implementing NAND flash (SLC) in a 153-ball VFBGA package. It integrates a MultiMediaCard controller with NAND flash and implements the JEDEC/MMC standard version 5.1 interface for embedded storage.

Designed for automotive-grade applications, this device supports high-speed boot, secure and partitioned storage, and on-die management features to address system boot, firmware storage, large-capacity data logging, and secure key/credential storage within constrained board space.

Key Features

• Memory Type & Capacity — 512 Gbit NAND flash (SLC) organized as 64G × 8, providing large onboard non-volatile storage.
• e.MMC 5.1 Interface — JEDEC/MMC Standard No. JESD84-B51-compliant e.MMC 5.1 interface with support for command queue, multiple partitions, and RPMB (Replay-Protected Memory Block).
• High-Speed I/O Options — Advanced 12-signal interface with selectable ×1, ×4, and ×8 I/Os; e.MMC I/F clock frequency up to 200 MHz and boot frequency 0–52 MHz; supports HS200/HS400 modes.
• Power Supply — VCC supply range 2.7 V to 3.6 V; VCCQ supply 1.70 V to 1.95 V.
• System and Data Protection — Built-in ECC and block management, reliable write, temporary and permanent write protection, discard and sanitize, power-off notification, and thermal protection.
• Functional & Safety Features — Hardware reset, high-priority interrupt (HPI), field firmware update (FFU), device health report, and background operation support as described in device documentation.
• Automotive Qualification & Temperature Range — AEC-Q100 qualification and specified operating temperature from −40°C to +105°C (TA).
• Package — 153-ball VFBGA package, supplier device package specified as 153-VFBGA (11.5 × 13 mm).

Typical Applications

• Automotive Infotainment and Telematics — High-capacity local storage for multimedia, map data, and application firmware where robust boot and partitioning features are required.
• System Boot and Firmware Storage — High-speed boot operation and reliable write features support firmware image storage and fast system startup.
• Secure Storage — RPMB and write-protection features enable secure credential and configuration storage for safety-critical functions.
• Data Logging and Event Recording — Large onboard capacity and background operation make the device suitable for long-term data logging and event storage in embedded systems.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q100 qualification and an extended operating range of −40°C to +105°C support deployment in automotive environments.
• Standards-Based Integration: JEDEC/MMC 5.1 compliance and support for HS200/HS400 modes enable straightforward integration with e.MMC hosts implementing the same standard.
• Flexible Performance Scaling: Selectable ×1/×4/×8 I/Os and up to 200 MHz clocking allow designers to balance throughput and signal/pin constraints.
• Integrated Data Management: On-die ECC, block management, reliable write, and power-off notification reduce host software complexity for data integrity and recovery.
• Secure and Partitioned Storage: RPMB, multiple enhanced partitions, and write-protection mechanisms provide segregated secure storage and controlled access.
• Compact, High-Density Package: 153-ball VFBGA (11.5 × 13 mm) provides high capacity in a compact footprint suitable for space-constrained PCBs.
