EN35SXR512A-104WIP(2PC)

The EN35SXR512A-104WIP(2PC) is a 512 Mbit serial SPI NOR flash memory device in the EON™ EN35SXR512A series. It implements a serial SPI architecture (Single/Dual/Quad I/O) optimized for code and data storage in industrial embedded systems.

Designed for robust in-system updates and secure data partitioning, the device combines high read performance with uniform 4-Kbyte sector architecture, hardware/software write protection and industrial temperature range for reliable operation in demanding environments.

Key Features

• Density & Organization — 512 M-bit (65,536 KByte) capacity organized as 64M × 8 with 262,144 programmable pages and 256 bytes per page.
• Serial SPI Interface — Supports Standard, Dual and Quad SPI modes with SPI-compatible signals (CLK, CS#, DI/DO and DQ₀–DQ₃) and SPI Mode 0 and Mode 3 operation.
• High-Speed Read — Supports Fast Read at up to 104 MHz for Single/Dual/Quad I/O and up to 133 MHz for Quad I/O Fast Read (series specification).
• Voltage Range — Operates as a 1.8V serial flash device with a full voltage range of 1.65–1.95 V (regulated 1.8–1.95 V per series datasheet).
• Uniform Sector Architecture — 16,384 uniform sectors of 4 KByte each, plus larger block and chip erase options for flexible memory management.
• Program/Erase Performance — Typical page program time 0.5 ms; typical sector erase time 40 ms, half-block 200 ms, block 300 ms and chip erase 120 s (typical values documented in the series datasheet).
• Reliability & Endurance — Minimum 100K program/erase cycles per sector and a data retention specification of 20 years.
• Protection & Security — Software and hardware write protection, WP# pin enable/disable, lockable 3 × 512-byte OTP sector, Read Unique ID and Replay-Protected Monotonic Counter (RPMC).
• Power Consumption — Low-power design with typical active current ≈24 mA and typical power-down current ≈2 µA (series typical values).
• Package & Temperature — Surface-mount 8-pin WSON 5×6 mm (supplier device package) and industrial operating temperature range −40 °C to 85 °C.
• Standards & Discoverability — Supports Serial Flash Discoverable Parameters (SFDP) for device parameter discovery.

Typical Applications

• Embedded Firmware Storage — Stores system firmware and boot code with uniform sectors that allow targeted sector/block updates and secure protection for code regions.
• Field Upgrades & Code Patching — Enables in-system code patches and partial memory updates using sector-level erase/program and software/hardware protection features.
• Data Logging & Configuration — Provides non-volatile storage for configuration data, calibration tables and logged data with long retention and high endurance.
• Industrial Controls — Suited for industrial embedded controllers and devices requiring industrial temperature range and robust write-protect mechanisms.

Unique Advantages

• Flexible SPI I/O Modes — Standard, Dual and Quad SPI support lets designers scale read throughput without changing the memory family.
• Uniform 4-KB Sectors — Fine-grained sector architecture simplifies partial updates and reduces erase/program overhead for small code or data changes.
• Comprehensive Protection Options — Combined software and WP# hardware protection plus lockable OTP improves control over writable regions and enhances security for critical data.
• Industrial Temperature Range — Rated for −40 °C to 85 °C to meet temperature demands of factory, building automation and industrial applications.
• High Endurance and Long Retention — Minimum 100K program/erase cycles and 20-year data retention support long service life in deployed systems.
• Low Power Standby — Microamp-level power-down current helps reduce standby energy use in battery-assisted or low-power applications.
