F59L4G81KSA-25BIG2N

The F59L4G81KSA-25BIG2N from ESMT is a 4.295 Gbit SLC NAND Flash memory device organized as 512M × 8 and supplied in a 63-ball BGA surface-mount package. Built for industrial use, the device implements parallel NAND architecture with command/address/data multiplexed on the DQ port and supports standard NAND program, erase and read operations.

This device is suited for high-density non-volatile storage in industrial embedded systems, offering a 2.7 V to 3.6 V supply range, JEDEC qualification, and an extended operating temperature range of −40 °C to 85 °C for robust operation in demanding environments.

Key Features

• Memory Architecture 4.295 Gbit SLC NAND organized as 512M × 8 with two stacked 2Gb dies; page size is 2K + 128 bytes and data register size matches the page length (2176 bytes).
• Performance Read cycle is specified at 25 ns and access time listed as 20 ns; random read latency is specified at 25 µs (max.) enabling fast read operations for embedded storage tasks.
• Program & Erase Timing Typical page program time is 400 µs (typ.) with a 700 µs maximum; block erase time is 3 ms (typ.) with a 10 ms maximum, supporting predictable program/erase timing.
• Endurance & Retention SLC cell architecture with endurance rated at 50K program/erase cycles and uncycled data retention of 10 years at 55 °C.
• Supply & I/O Operates from 2.7 V to 3.6 V (VCC ~3.3 V nominal) with an 8-bit parallel DQ interface for command/address/data multiplexing.
• Reliability & Protection Hardware data protection and program/erase lockout during power transitions are supported; ECC requirement is 8-bit per 512 bytes.
• Capacity & Organization Block size is 64 pages (128K + 8K bytes) with 2048 blocks per die (LUN), and support for features such as cache program/read, copy-back, two-plane operation and automatic page 0 read at power-up.
• Package & Grade Industrial-grade device in a 63-ball BGA (BGA-63) surface-mount package with JEDEC qualification and operating range −40 °C to 85 °C.

Typical Applications

• Industrial Embedded Storage High-density non-volatile storage for industrial controllers and data-loggers where extended temperature range and JEDEC qualification are required.
• Solid-State File Storage File and image storage in embedded systems that need predictable program/erase timing and SLC endurance characteristics.
• Boot and Firmware Storage Boot-from-NAND support and automatic page 0 read at power-up make the device suitable for firmware storage and system boot ROM replacement.
• Media and Recording Devices Voice or image file memory in devices that leverage the page and block organization along with cache program/read and copy-back operations.

Unique Advantages

• SLC Endurance and Retention: 50K P/E cycles and 10-year uncycled retention at 55 °C provide predictable longevity for long-life industrial deployments.
• Stacked Die Organization: Two 2Gb dies stacked into a 4Gb device support operations that leverage multi-die arrangements while maintaining standard NAND page and block semantics.
• Predictable Timing: Documented program and erase times (400 µs page program typical; 3 ms block erase typical) enable deterministic system-level flash management.
• Robust Power Range: Wide VCC range (2.7 V–3.6 V) permits operation across common 3.3 V industrial power rails and supports reliable behavior during power transitions via lockout protection.
• System-Level Features: Built-in cache program/read, two-plane operation, copy-back, and automatic memory download/boot options simplify integration for firmware updates and high-throughput transfers.

Why Choose F59L4G81KSA-25BIG2N?
