F59L2G81KA-25BG2N

The F59L2G81KA-25BG2N is a 2 Gbit (256M x 8) single-level cell (SLC) NAND flash memory device from ESMT, supplied for parallel interface applications. It operates from a 2.7 V to 3.6 V supply and is offered in a 63-ball BGA package for surface-mount integration.

Designed for high-density non-volatile storage, the device supports page- and block-level operations with features such as automatic program/erase, cache read/program, and boot-from-NAND options. Typical target uses include solid-state file storage, image and voice record memory, and embedded storage in consumer and industrial designs within a commercial temperature range.

Key Features

• Memory Architecture – 2.147 Gbit organized as 256M × 8 with a page size of (2K + 128) bytes and a block size of 64 pages (128K + 8K bytes).

• Performance – Device offered with a 25 ns speed grade (ordering code “-25”); read cycle and random-read timings specified in the datasheet (read cycle 25 ns, random read 25 µs max).
• Program & Erase Timing – Typical page program time 400 µs (700 µs max); block erase typical 3 ms (10 ms max).
• Reliability & Endurance – Endurance rated at 50K program/erase cycles and uncycled data retention specified as 10 years at 55°C; ECC requirement: 8-bit per 512-byte.
• Interface & Operation – Parallel command/address/data multiplexed DQ port with support for cache program/read, copy-back, two-plane operation and EDO mode; automatic program and erase control.
• Power & Package – Supply voltage range 2.7 V to 3.6 V; commercial operating temperature 0 °C to 70 °C; 63-ball BGA (BGA-63) surface-mount package.
• System Protection – Hardware data protection and program/erase lockout during power transitions; automatic page 0 read at power-up option.

Typical Applications

• Solid-state file storage – High-density non-volatile storage for embedded file systems and removable media implementations.
• Still cameras & imaging – Image file memory for cameras where large sequential and random storage is required.
• Voice recording – Non-volatile store for voice data with reliable program/erase cycling.
• Embedded storage for consumer/industrial devices – Boot-from-NAND and automatic memory download support for system firmware and application data.

Unique Advantages

• SLC endurance – 1 bit per cell SLC architecture with 50K P/E cycle rating provides longevity for write-intensive embedded applications.
• High-density organization – 256M × 8 organization and 2 Gbit capacity enable compact designs that require substantial non-volatile storage without additional components.
• Flexible performance modes – Cache program/read, two-plane and copy-back operations allow designers to optimize throughput for specific workloads.
• Robust data retention – Datasheet specifies 10-year uncycled data retention at 55 °C, supporting long-term storage requirements.
• System-friendly features – Hardware data protection and power-transition lockout reduce risk during system-level power events; automatic page 0 read simplifies boot workflows.
• Compact BGA footprint – 63-ball BGA packaging supports high-density board designs and reliable surface-mount assembly.
