EMMC04G-CT32-02DB0

The EMMC04G-CT32-02DB0 is a 4GB packaged managed NAND flash device implementing the e•MMC™ 5.1 interface. It combines NAND flash memory and an onboard e•MMC controller to provide standard host-side access and offload flash management tasks from the host processor.

Designed for commercial and industrial applications, the device supports high-speed modes up to 200 MHz and provides integrated data integrity and management features for reliable embedded storage across a wide operating temperature range.

Key Features

• Core / Architecture Packaged managed NAND flash with an onboard e•MMC™ controller compliant with JEDEC e•MMC™ 5.1 (JESD84-B51), enabling standard host interface and internal flash management.
• Memory 4GB capacity in FLASH format. Memory organization is specified as 128G × 8.
• Interface & Bus Modes e•MMC interface with a ten-wire bus (clock, 1-bit command, 8-bit data) and optional hardware reset. Supports 1-bit, 4-bit and 8-bit data widths and alternate boot operation mode.
• Performance Variable clock frequencies from 0–200 MHz. Supports Single data transfer (up to 52 MB/s @ 52 MHz), DDR-104 (up to 104 MB/s @ 52 MHz), HS-200 (up to 200 MB/s @ 200 MHz) and HS-400 (up to 400 MB/s @ 200 MHz).
• Operating Voltage & Temperature Operating voltage options listed as VCCQ = 1.8 V / 3.3 V and VCC = 3.3 V. Rated for operation from −25 °C to +85 °C and storage from −40 °C to +85 °C.
• Data Integrity & Reliability Internal ECC, Cyclic Redundancy Code (CRC) for command/data communication, enhanced data management algorithms, secure bad block erase and enhanced write protection (permanent and partial).
• Power & Field Management Power-off notification for sleep, host-initiated explicit sleep (CMD5), data protection for sudden power failure during program operations, and field firmware update (FFU).
• System & Maintenance Features Device health report, production state awareness, pre-EOL information, command queuing, cache flush and cache barrier reporting, background operation control and High Priority Interrupt (HPI).
• Package 153-ball JEDEC WFBGA package (153-FBGA, 9 × 7.5 mm) in a RoHS-compliant package description.
• Endurance Endurance specified at 3,000 program–erase cycles.

Typical Applications

• Industrial systems — Reliable onboard storage for firmware, system logging and application data across −25 °C to +85 °C operating conditions.
• Commercial embedded devices — Boot and application storage where an integrated e•MMC controller simplifies host design and flash management.
• Consumer and networking equipment — Embedded non-volatile storage for firmware, configuration and temporary data buffering using standard e•MMC interface modes.

Unique Advantages

• Highly integrated solution: Onboard e•MMC controller manages NAND media (ECC, wear-leveling and bad block management), reducing host software complexity.
• Flexible performance modes: Supports multiple bus widths and modes including HS-200 and HS-400 for scalable throughput up to the listed mode limits.
• Data integrity features: CRC for command/data, internal ECC and power-failure protection help maintain reliable data storage and communication.
• Field firmware update capability: FFU support enables in-field device firmware upgrades without replacing hardware.
• Operational robustness: Rated for −25 °C to +85 °C operation and includes production state reporting, device health, and pre-EOL information for lifecycle management.
• Compact, industry-standard package: 153-ball WFBGA (9 × 7.5 mm) provides a small-footprint integration option for embedded designs.
