Key Features

• Memory Architecture  32 M‑bit density with a 4M × 8 organization providing 4,096 KByte total capacity, organized as 16,384 pages of 256 bytes each.
• Interface & Performance  Serial SPI compatible (Mode 0 and Mode 3) with Standard, Dual and Quad SPI support and a 104 MHz clock rate for 1‑, 2‑ and 4‑bit transfers; configurable dummy cycles for timing optimization.
• Program & Erase  Page program typical time 1 ms; sector erase typical 100 ms; half‑block erase typical 300 ms; block erase typical 500 ms; chip erase typical 30 seconds.
• Sector & Block Organization  Uniform sector architecture with 1,024 sectors of 4 Kbyte, 128 blocks of 32 Kbyte and 64 blocks of 64 Kbyte; any sector or block can be erased individually.
• Write Protection & Security  Software and hardware write protection with WP# pin, lockable 3 × 1,024‑byte OTP security sector, and support for Read Unique ID and SFDP signature.
• Reliability  Minimum 100,000 program/erase cycles per sector or block and typical data retention of 20 years.
• Low Power  Typical active current around 10 mA and typical power‑down current around 1 µA.
• Power Supply  Single power supply operation; full voltage range shown in documentation.
• Package & Temperature  Available in an 8‑lead SOP (200 mil) surface‑mount package; industrial temperature range −40 °C to 85 °C; RoHS compliant.
• Additional System Features  Support for write‑suspend and write‑resume, volatile status register bits, and configurable protection enabling partial memory protection while allowing targeted updates.

Typical Applications

• Industrial Control & Automation  Non‑volatile storage for firmware and configuration data where industrial temperature range and endurance are required.
• Embedded Systems & Microcontroller Boot  Code and parameter storage for embedded platforms that require fast SPI reads and support for Dual/Quad I/O.
• Field Upgradeable Devices  Systems that need block/sector‑level erase and robust write protection for in‑field firmware updates.
• Instrumentation & Test Equipment  Persistent storage of system settings and calibration data with long data retention and high endurance.

Unique Advantages

• High‑speed SPI access: 104 MHz operation for fast code and data reads, reducing boot and load latencies.
• Flexible I/O modes: Standard, Dual and Quad SPI support enables scalable throughput across a range of host controllers.
• Granular erase and protection: 4 Kbyte uniform sectors plus software/hardware protection let you update small regions without exposing the entire memory.
• Designed for reliability: 100k program/erase cycles and 20 years data retention provide longevity for deployed systems.
• Low standby power: 1 µA typical power‑down current supports energy‑sensitive designs.
• Industrial ready: Surface‑mount 8‑lead SOP (200 mil) package and −40 °C to 85 °C operating range align with industrial deployment requirements.
