EN35QX512A-104FIP(2SC)

The EN35QX512A-104FIP(2SC) is a 512 Mbit serial NOR Flash memory device featuring a Serial Peripheral Interface (SPI) architecture with standard, Dual and Quad I/O support. Designed for industrial use, the device delivers high-density non-volatile storage with uniform 4-Kbyte sectors, robust program/erase endurance and long data retention for embedded firmware and code storage.

With support for high-speed Fast Read modes at up to 104 MHz (Single/Dual/Quad I/O) and Quad I/O operation to 133 MHz under specified supply conditions, the part targets applications that require fast, flexible read performance, selective sector erase and software/hardware write protection.

Key Features

• 512 Mbit Serial Flash capacity — 512 M-bit (65,536 KByte) memory organized as 64M × 8 with 262,144 programmable pages.
• SPI-compatible interface — Standard, Dual and Quad SPI support; Standard SPI signals: CLK, CS#, DI, DO; Dual and Quad DQ pins supported for higher throughput.
• High-speed read modes — 104 MHz clock rate for Single/Dual/Quad I/O Fast Read; Quad I/O Fast Read can run to 133 MHz under the specified 3.0–3.6 V supply range.
• Uniform sector architecture — 16,384 × 4-Kbyte sectors; also arranged as 2,048 × 32-Kbyte and 1,024 × 64-Kbyte blocks; any sector or block can be erased individually.
• Program and erase performance — Page program typical time 0.5 ms; Sector erase typical 40 ms; Half-block erase typical 200 ms; Block erase typical 300 ms; Chip erase typical 120 s.
• Write protection and security — Software and hardware write protection options; lockable 3 × 512‑byte OTP security sector and volatile status register bits for protection control.
• Endurance and retention — Minimum 100K program/erase cycles per sector or block and 20 years data retention as specified.
• Power and consumption — Low power design with typical active current around 14 mA and typical power-down current of 2 μA.
• Flexible addressing and discovery — Supports 3-byte and 4-byte address modes and Serial Flash Discoverable Parameters (SFDP) signature.
• Industrial-grade package and temperature — Available in 16‑pin SOP 300 mil surface-mount package; industrial operating temperature range −40 °C to 85 °C.

Typical Applications

• Embedded firmware storage — Store boot code and firmware images with sector-level erase and protection to enable selective updates without affecting other regions.
• Field-upgradeable systems — Use Quad/ Dual SPI fast read and page program capability for in-field firmware update and code patching scenarios.
• Industrial controllers and instrumentation — Industrial temperature rating and robust endurance make it suitable for non-volatile code and parameter storage in industrial devices.
• High-density non-volatile data logging — Large 512 Mbit capacity with uniform sectors supports large-scale data capture and managed erase cycles.

Unique Advantages

• High-density, single-chip storage: 512 Mbit capacity reduces board-level BOM and simplifies designs that need large non-volatile space.
• Selective erase and fast program: 4-Kbyte uniform sectors with typical 0.5 ms page program and 40 ms sector erase enable efficient updates and low maintenance windows.
• Flexible high-speed I/O: Standard, Dual and Quad SPI support plus Fast Read modes (104 MHz and conditional 133 MHz) provide scalable throughput for varied system requirements.
• Robust protection features: Software/hardware write protection and a lockable OTP sector help safeguard critical code and configuration data.
• Industrial readiness: Surface-mount 16‑pin SOP 300 mil packaging and −40 °C to 85 °C operating range meet the needs of industrial applications.
• Longevity and reliability: Specified ≥100K program/erase cycles and 20-year data retention support long-life deployments.
