Overview of JS27HP4G08SDDA-45 – 2K page 4-bit ECC 128 byte spare
The JS27HP4G08SDDA-45 is a 4 Gbit SLC NAND Flash memory in an x8 organization, designed for industrial embedded storage. It implements 2K main pages with 128 bytes of spare area and 4-bit ECC to support robust data integrity in mass storage and industrial applications.
Built for 1.8V operation with a parallel NAND interface and a compact 63-ball FBGA package, this device targets industrial-grade systems that require endurance, predictable program/erase timing, and wide operating temperature range.
Key Features
- Memory Core & Density 4 Gbit SLC NAND Flash with x8 organization and 2K-byte page size plus 128-byte spare area for metadata and ECC.
- Error Correction & Data Integrity 4-bit ECC (applied per 528 bytes for x8 devices) to support reliable data retention and error correction across program/erase cycles.
- Performance 45 ns access time (sequential, 1.8V), 22.22 MHz clock frequency, typical page program time 300 µs and typical block erase time 3.5 ms (4Gb device).
- Interface & Operation Parallel NAND interface, x8 I/O, ONFI 1.0 compliant command set, with Copy Back Program and Cache Read to simplify data movement and improve throughput.
- Power 1.8V supply operation (Vcc = 1.7 V to 1.95 V for 1.8V devices) for low-voltage system integration.
- Reliability & Endurance Typical 10 years data retention and endurance rated to 100,000 program/erase cycles at -40°C to 85°C (industrial), with hardware protections that lock program/erase during power transitions.
- Package & Mounting 63-ball FBGA surface-mount package (9.0 × 11.0 × 1.0 mm) for compact board-level integration.
- Operating Range Industrial temperature grade from -40°C to 85°C for use in temperature-challenging environments.
Typical Applications
- Industrial Storage High-endurance SLC NAND well suited for embedded industrial file systems, factory automation controllers, and on-board program storage.
- Data Logging & Telemetry Reliable long-term data retention and endurance make this device a fit for logging sensor data and telemetry in industrial monitoring systems.
- Embedded Mass Storage 2K/128B page structure with 4-bit ECC supports mass storage use in single-board computers and embedded appliances.
- Firmware / Code Flash Fast program and predictable erase times support firmware storage and in-field updates where integrity and endurance are required.
Unique Advantages
- Robust ECC-protected storage: 4-bit ECC per 528 bytes improves data reliability across cycles and supports sustained use in industrial applications.
- Industrial temperature support: Rated -40°C to 85°C to meet environmental needs for many embedded and factory-deployed systems.
- Low-voltage operation: 1.8V supply range reduces system power and eases integration with low-voltage logic domains.
- Compact, board-friendly package: 63-ball FBGA (9.0 × 11.0 mm) enables dense, surface-mount designs while preserving I/O and functionality.
- Predictable program/erase performance: Typical page program time of 300 µs and block erase times around 3.5 ms provide consistent timing for real-time and control applications.
- ONFI-compatible command set and advanced NAND features: Copy Back Program, Cache Read, and electronic signature support simplify integration and firmware control.
