F59D4G81XB-IP(2X)

The ESMT F59D4G81XB (2X) is a 1.8V single-level cell (SLC) NAND flash memory device organized as 512M × 8 and offering 4.295 Gbit of non-volatile storage. Designed as an industrial-grade NAND solution, it provides ONFI 1.0-compliant asynchronous parallel interface and a low-voltage 1.8 V supply for embedded storage and firmware applications.

With SLC technology, internal ECC options, and up to 100,000 program/erase cycles, the device targets applications that require durable, long-retention non-volatile memory in temperature ranges down to −40 °C.

Key Features

• Memory Technology Single-level cell (SLC) NAND flash organized as 512M × 8 delivering 4.295 Gbit of non-volatile storage.
• Voltage and Interface 1.8 V supply range (1.7 V–1.95 V documented in the datasheet) with a parallel asynchronous I/O interface and ONFI 1.0 compliance for command/address/data operations.
• Performance and Timing Asynchronous I/O performance with specified access times; typical program/page and read/page timings include program page ~200 μs (typ) and read page down to 30–170 μs depending on ECC configuration.
• Memory Organization & Capacity Page size of 4,352 bytes (4,096 + 256 spare), block size of 64 pages, single plane organization and device size of 4 Gbit (512M × 8).
• Reliability & Endurance Endurance rated to 100,000 program/erase cycles with uncycled data retention documented for 10 years at 85 °C and JESD47G-compliant data retention practices.
• Data Integrity & Management 8-bit internal ECC available (disabled by default, toggled via SET FEATURE), permanent block locking, block lock/OTP mode and internal data-move support within a plane.
• Command & Feature Set ONFI NAND protocol with advanced commands including program/read page cache modes, read unique ID, programmable drive strength, and operation status reporting (status byte, R/B#).
• Package & Mounting Multiple surface-mount packages available: 48‑pin TSOPI, 63‑ball BGA and 67‑ball BGA options for flexible board-level integration.
• Operating Temperature Specified operating range down to −40 °C up to 85 °C.
• Qualification & Compliance JEDEC qualification and RoHS compliance indicated in product data.

Typical Applications

• Embedded Storage Non-volatile storage for firmware, boot code and system images where SLC endurance and retention are required.
• Industrial Controllers Durable code and data storage for machine control, PLCs and industrial automation operating across −40 °C to 85 °C.
• Data Logging High-reliability event and sensor data recording in instrumentation and monitoring systems.
• Firmware and Boot Media Persistent storage for boot loaders, secure firmware blocks and device configuration with OTP and block-lock capabilities.

Unique Advantages

• SLC Endurance: 100,000 program/erase cycles provide extended device lifetime for frequent-write applications.
• Long Data Retention: Uncycled data retention specified at 10 years at 85 °C supports long-term storage requirements.
• ONFI Compliance: Standard ONFI 1.0 command and interface support simplifies integration with existing NAND controllers.
