Key Features

• Memory Organization and Capacity — 32 Megabit device organized as 4,194,304 bytes (4M × 8 or 2M × 16) to support byte‑ or word‑wide interfaces.
• Fast Read Access — Access times as fast as 70 ns to support high‑performance microprocessor systems and reduce wait‑state requirements.
• Program / Erase Performance — Typical word program time of 15 µs, sector erase time of 100 ms, and chip erase time of 8 s for efficient code updates and field reprogramming.
• Flexible Sector Architecture — Eight 8‑Kbyte sectors and sixty‑three 64‑Kbyte sectors, with 8‑Kbyte sectors allocated for Top or Bottom boot configuration and sector group protection features.
• Data Protection Features — Hardware sector locking, temporary sector unprotect for controlled updates, and a secured silicon sector (128‑word area) that can be permanently protected.
• Power and I/O — Single power supply operation across 2.7 V to 3.6 V; low power consumption with typical active read current of 9 mA, typical program/erase current of 20 mA, and standby current <1 µA.
• Reliability and Endurance — Minimum 100K program/erase cycles per sector and 20‑year data retention as specified.
• System Features — Separate OE#, CE# and WE# controls, RESET# hardware reset pin, WP#/ACC pin for write protection and accelerated program times, DATA# polling and toggle bit support, and Erase Suspend/Resume capability.
• Standards and Interface — JEDEC standard compatible and supports JEDEC Common Flash Interface (CFI) for system integration.
• Package and Temperature — 48‑ball TFBGA (6 × 8 mm) surface‑mount package; industrial operating temperature range −40 °C to 85 °C.

Typical Applications

• Industrial Control and Automation — Non‑volatile storage for firmware and boot code in industrial controllers operating across −40 °C to 85 °C.
• Embedded Systems — Code and data storage for microprocessor‑based systems requiring fast random access and reliable program/erase cycles.
• System Boot and Firmware Update — Top‑boot sector configuration and sector‑level protection permit secure boot storage and controlled in‑field updates.

Unique Advantages

• Fast System Responsiveness: 70 ns access time minimizes wait states for high‑performance processors.
• Controlled Field Updates: Sector locking plus temporary unprotect and Erase Suspend/Resume enable secure, flexible firmware maintenance.
• Compact Industrial Package: 48‑ball TFBGA (6 × 8 mm) surface‑mount footprint saves board space while meeting industrial temperature requirements.
• Robust Endurance and Retention: Specified minimum 100K program/erase cycles per sector and 20‑year data retention support long product lifecycles.
• Low Power Operation: Typical active and standby currents (9 mA read, 20 mA program/erase, <1 µA standby) help manage system power budgets.
• JEDEC Compatibility: JEDEC and CFI support simplifies integration into standard embedded toolchains and boot loaders.
