EMMC04G-WT32-02D10

The EMMC04G-WT32-02D10 is a packaged managed NAND flash storage device implementing the JEDEC e•MMC™ 5.1 standard. It integrates multi-level cell (MLC) NAND flash with an onboard e•MMC controller to provide a standard interface and internal flash management for embedded systems.

Designed for commercial and industrial use, this device delivers high-speed transfer modes, flexible bus widths and wide operating temperature support, making it suitable for embedded boot media and general-purpose non-volatile storage where integration and reliable data management are required.

Key Features

• Core / Integration Packaged managed NAND flash with an onboard e•MMC controller that handles error control, wear-leveling and NAND management.
• Memory 32 Gbit (4G x 8) MLC NAND flash providing 4 GB of non-volatile storage in a single packaged device.
• Interface & Bus Modes JEDEC e•MMC™ 5.1 interface supporting 1-bit (default), 4-bit and 8-bit data widths. Ten-wire bus interface (clock, 1-bit command, up to 8-bit data) with optional hardware reset.
• Performance Modes Variable clock frequencies up to 200 MHz with supported transfer modes including HS-200, HS-400 (up to 400 MB/s @ 200 MHz), DDR-104 and single data rate modes.
• Power & Voltage Supply voltage range 2.7 V to 3.6 V. Datasheet notes VCCQ options of 1.8 V / 3.3 V and VCC = 3.3 V for interface configurations.
• Reliability & Data Integrity Internal ECC, Cyclic Redundancy Code (CRC) for command/data communication, data protection for sudden power failure during program operations, and enhanced write protection options (permanent and partial).
• Advanced Management & Security Features include field firmware update (FFU), device health report, production state awareness, secure bad block erase commands, RPMB throughput improvements and command queuing.
• Package & Temperature 153-ball JEDEC FBGA package (153-WFBGA / 153-FBGA, 11.5 × 13 mm) rated for operating and storage temperature range of -40°C to +85°C.

Typical Applications

• Industrial Systems — Non-volatile storage for industrial controllers and instrumentation that require wide temperature operation and integrated flash management.
• Commercial Embedded Devices — Universal storage for embedded platforms where an industry-standard e•MMC interface and onboard media management simplify system design.
• Embedded Boot Media — Supports alternate boot operation mode to provide a simple boot sequence for host processors.
• Wide‑Temperature Equipment — Storage for equipment operating across -40°C to +85°C environments.

Unique Advantages

• Integrated managed NAND: Onboard controller relieves the host of flash management tasks such as wear-leveling and error correction.
• High-speed transfer capability: HS-400 and HS-200 modes plus DDR options enable higher sustained throughput where required.
• Flexible interface options: Support for 1/4/8-bit bus widths and variable clock up to 200 MHz allows tuning for performance and pin-count trade-offs.
• Robust data integrity: Internal ECC, CRC checks, power-fail data protection and secure erase features improve reliability of stored data.
• Field maintainability: Field firmware update and device health reporting support in-field servicing and lifecycle management.
• Industrial-grade thermal range: Rated for -40°C to +85°C to suit commercial and industrial deployment environments.
