Overview of JS27HP4G08SFDA-45 – 4K page 4-bit ECC 256 byte spare
The JS27HP4G08SFDA-45 is a 4 Gbit single-level cell (SLC) NAND Flash memory device with an x8 I/O organization and a 1.8 V supply. It provides 4K page architecture with 256 bytes spare, ONFI 1.0 compliant command set, and features intended for mass storage and embedded code-storage applications.
Designed for industrial environments, the device supports a wide operating temperature range (−40°C to 85°C) and is supplied in a compact 63-ball FBGA (9.0 × 11.0 mm) package for surface-mount integration.
Key Features
- Core & Memory — 4 Gbit capacity, SLC NAND Flash organized as x8 I/O with 4K page size plus 256-byte spare for error management.
- Performance — Sequential access timing down to 45 ns and random read access typical figures documented; program time (typical) 300 µs and block erase time (typical) 3.5 ms.
- Error Correction & Reliability — 4-bit ECC implementation (per 528 bytes) and specified endurance of 100,000 program/erase cycles (typical) with a 10‑year data retention specification (typical).
- Interface & Compatibility — Parallel x8 interface, ONFI 1.0 compliant command set and support for features such as Read Cache and Copy Back Program.
- Power — 1.8 V operating voltage with VCC/VCCQ operating range documented as 1.7 V to 1.95 V in the product specification.
- Package & Mounting — 63-ball FBGA (9.0 × 11.0 mm, 63-BGA) surface-mount package, lead/halogen free.
- Industrial Temperature Range — Rated for operation from −40°C to 85°C for deployment in industrial environments.
- Security & Identification — One-Time Programmable (OTP) area and a unique serial number (Read Unique ID) for device identification.
- Standards & Compliance — ONFI 1.0 compliant; RoHS directive compliant.
Typical Applications
- Embedded Mass Storage — Cost-effective SLC storage for embedded systems requiring durable flash with ECC and long data retention.
- Code and Boot Storage — Suitable for firmware and boot code storage; CE# don't care function allows direct code download by a microcontroller.
- Industrial Control — Non-volatile data logging and configuration storage in industrial equipment across the −40°C to 85°C operating range.
- Consumer & Professional Products — Solid-state mass storage applications where SLC endurance and data integrity are priorities.
Unique Advantages
- SLC Technology for Endurance: Single-level cell design and 100,000 program/erase cycle specification (typical) support long-lived storage in demanding applications.
- Robust Data Integrity: 4-bit ECC per 528 bytes and a 256-byte spare area provide on-chip error correction to maintain reliable data retention.
- Industrial Temperature Range: −40°C to 85°C rating enables deployment in harsh environments without derating.
- Compact Surface-Mount Package: 63-ball FBGA (9.0 × 11.0 mm) minimizes PCB area while providing a standard surface-mount footprint for automated assembly.
- ONFI 1.0 Compatibility: Standardized command set and read-cache capabilities simplify integration with ONFI-compatible controllers and systems.
- Low-Voltage Operation: 1.8 V nominal supply (VCC/VCCQ: 1.7 V–1.95 V) helps support low-power designs and modern system power rails.
