JS27HU4G08SDDA-25M

The JS27HU4G08SDDA-25M is a 4 Gbit SLC NAND flash memory organized as x8 with 2K-byte main pages and 128-byte spare area, implementing 4-bit ECC for enhanced data integrity. It provides a parallel NAND interface and is targeted at solid-state mass storage and embedded storage applications that require durable non-volatile memory with fast read performance and robust error correction.

With a 3.3 V supply range, a 63-ball FBGA package (9.0 × 11.0 mm), and an operating temperature range from -40 °C to 105 °C, this device supports compact, surface-mount designs that need reliable long-term data retention and high program/erase endurance.

Key Features

• Memory Core 4 Gbit SLC NAND organized as x8 with 2K-byte main page plus 128-byte spare area for efficient storage and management.
• Error Correction 4-bit ECC capability to support improved data integrity across stored pages (per datasheet ECC configuration: 4-bit ECC per 528 bytes for x8 organization).
• Performance Fast sequential read timing (25 ns cycle) and page program time typical 300 µs; random page read/access times consistent with NAND operation characteristics.
• Interface & Command Set Parallel x8 NAND interface with ONFI 1.0 compliant command set, including features such as cache read and copy back programming for efficient data moves.
• Power 3.3 V supply (device Vcc operating range per datasheet: 2.7 V–3.6 V) suitable for common embedded power rails.
• Reliability 10 years typical data retention; endurance specified in datasheet up to 100,000 program/erase cycles at moderated temperatures and 60,000 cycles across an extended temperature range when using 4-bit ECC.
• Package & Mounting 63-ball FBGA (9.0 × 11.0 × 1.0 mm) in a surface-mount form factor to minimize board area while providing robust soldered connections.
• Environmental RoHS compliant (lead-free & halogen-free package per datasheet).

Typical Applications

• Solid-State Mass Storage Cost-effective NAND flash storage for media, data logging, and high-capacity non-volatile storage applications.
• Embedded Systems Firmware and file system storage in embedded controllers and appliances that require fast read access and reliable data retention.
• Consumer & Industrial Devices Local non-volatile storage for devices where compact surface-mount memory and endurance are important.

Unique Advantages

• Large page with spare area: 2K main page plus 128-byte spare simplifies error management and metadata storage on a per-page basis.
• 4-bit ECC support: Enhanced error correction capability improves effective device endurance and data reliability for stored content.
• High endurance and retention: Datasheet-specified endurance and a typical 10-year data retention profile support long-term data storage requirements.
• ONFI-compliant command set: Standardized command interface and features such as cache read and copy back reduce integration effort.
• Compact FBGA package: 63-ball FBGA (9.0 × 11.0 mm) surface-mount package minimizes PCB footprint in space-constrained designs.
