F59L4G81XB-25TG2X

The F59L4G81XB-25TG2X from ESMT is a 4.295 Gbit single-level cell (SLC) NAND Flash device organized as 512M × 8 with a parallel 8-bit multiplexed interface. It supports VCC from 2.7V to 3.6V and operates across a commercial temperature range of 0 °C to 70 °C.

Designed for non-volatile storage in commercial embedded systems, the device implements the ONFI 1.0 command set and offers on-die ECC, program/read cache modes, and hardware status signals for robust integration into storage and firmware applications.

Key Features

• Memory Core & Organization — 4.295 Gbit total capacity organized as 512M × 8; page size 4,352 bytes (4,096 + 256), block size 64 pages, single plane.
• Performance — Asynchronous I/O with RC/WC = 25 ns and a listed access time of 20 ns. Read page times up to 115 µs (max) with on-die ECC enabled and 25 µs (max) with ECC disabled. Typical program page time is 200 µs (without on-die ECC) and 240 µs (with on-die ECC); typical erase block time is 2 ms.
• Interface & Signals — Standard ONFI NAND Flash protocol over a highly multiplexed 8-bit I/O bus (I/Ox), with CE#, CLE, ALE, WE#, RE#, R/B# and WP# for hardware-level control and status.
• Error Management & Security — Internal 8-bit ECC (disabled by default and configurable via SET FEATURE). Permanent block locking, one-time programmable (OTP) mode, block lock and Read Unique ID are supported.
• Reliability & Endurance — Endurance rated to 100,000 program/erase cycles; uncycled data retention of 10 years 24/7 at 70 °C; qualification referenced to JESD47G.
• Power & Temperature — Wide operating voltage range of 2.7 V to 3.6 V and commercial operating temperature of 0 °C to 70 °C.
• Package & Mounting — Surface-mount TSOPI-48 package (48-pin TSOPI, Pb-free) with a standard low pin-count NAND pinout that facilitates board upgrades across densities.

Typical Applications

• Embedded storage and firmware — Non-volatile storage for firmware, boot code and system images where program/erase endurance and long data retention matter.
• Commercial embedded systems — Fits designs requiring commercial-grade temperature operation (0 °C to 70 °C) and a standard parallel NAND interface.
• Data storage and logging — Suitable for designs that need reliable page/block program and erase performance combined with on-die ECC and long-term retention.

Unique Advantages

• SLC endurance and retention — Rated for 100,000 program/erase cycles and 10 years uncycled retention at 70 °C, providing predictable lifecycle behavior for non-volatile storage needs.
• Configurable on-die ECC — 8-bit internal ECC can be enabled or disabled via SET FEATURE, allowing system designers to balance error correction and raw throughput as required.
• ONFI 1.0 compatibility — Standard NAND command set and protocols simplify integration and future upgrades across ONFI-compliant devices.
• Fast asynchronous I/O — Low RC/WC (25 ns) and short program/read latencies support responsive read/write operations for embedded storage tasks.
• Flexible block management — Permanent block locking, OTP mode and block lock features support secure and reliable storage partitioning and protection.
• Compact surface-mount package — TSOPI-48 surface-mount form factor enables compact board designs while retaining a standard pinout for density upgrades.
