EN25S64A-104WIP(2SC)

The EN25S64A-104WIP(2SC) is a 64 Mbit serial NOR flash memory device in the ESMT EN25S64A series. It implements an SPI serial interface with support for Standard, Dual and Quad SPI access modes and is designed for code and data storage in industrial temperature environments.

With high-speed read modes up to 104 MHz, uniform 4-Kbyte sectors and hardware/software protection features, this device targets embedded systems requiring fast non-volatile storage, in-field firmware updates and robust block-level protection.

Key Features

• Capacity & Organization — 64 Mbit (8,192 KByte) organized as 8M × 8 with 32,768 pages and 256 bytes per programmable page.
• SPI Interface & Modes — Serial SPI architecture compatible with Mode 0 and Mode 3; supports Standard, Dual and Quad SPI for flexible performance and bus utilization.
• High-Speed Read — Fast read up to 104 MHz in Standard and Dual SPI modes (with configurable dummy cycles); Quad SPI up to 104 MHz with applicable dummy cycles.
• Uniform Sector Architecture — 2,048 × 4-Kbyte sectors, 256 × 32-Kbyte blocks and 128 × 64-Kbyte blocks; any sector or block can be erased individually.
• Program & Erase Performance — Typical page program time 0.5 ms; sector erase typical 40 ms; half-block and block erase times and full chip erase typical 32 seconds.
• Power Management — Low power consumption with typical active current ~3.5 mA and typical power-down current ~1 µA.
• Data Protection & Security — Software and hardware write protection, WP# pin option, software/hardware reset, and a lockable 512-byte OTP security sector; read unique ID number supported.
• Reliability — Minimum 100K program/erase cycles per sector/block and data retention time of 20 years.
• Industrial Grade & Packaging — Industrial operating temperature range −40°C to 85°C; surface-mount 8-pin WSON 5×6 mm package.
• Additional Performance — Configurable dummy cycles, write suspend/resume, and volatile status register bits for flexible system integration.

Typical Applications

• Embedded Firmware Storage — Store boot code and firmware with sector-level erase and program capability for in-field updates and patches.
• Code/Data Partitioning — Use block-level protection and software/hardware write-protect features to safeguard code segments while permitting updates to other memory regions.
• Configuration & Calibration Data — Retain critical configuration, calibration or device identity information using the lockable 512-byte OTP sector and unique ID read feature.

Unique Advantages

• Flexible SPI Performance — Standard, Dual and Quad SPI support at up to 104 MHz enables designers to balance throughput and pin usage according to system needs.
• Granular Protection Model — Uniform 4-Kbyte sectors and multiple protection mechanisms simplify secure firmware update strategies and reduce risk of accidental overwrite.
• Fast Program/Erase — Typical page program times (~0.5 ms) and sector erase times (~40 ms) help minimize update windows during in-field operations.
• Industrial Temperature Range — Rated for −40°C to 85°C to meet a broad set of industrial deployment scenarios.
• Low Power Operation — Low active and deep-power-down currents reduce system power consumption during idle and runtime.
• Long-Term Data Retention and Endurance — 100K program/erase cycles and 20-year data retention support durable embedded storage needs.
