EN35SY512A-104FIP(2PC)

The EN35SY512A-104FIP(2PC) is a 512 Mbit serial NOR flash memory from ESMT designed for high-density non-volatile code and data storage. It implements a Serial Peripheral Interface (SPI) architecture with single, dual and quad I/O modes, delivering fast read performance (up to 104 MHz for Single/Dual/Quad Fast Read and up to 133 MHz for Quad I/O Fast Read).

Engineered for industrial use, the device combines uniform-sector erase granularity, robust write-protection mechanisms and industry-grade operating range to support firmware storage, in-field code updates and reliable long-term data retention in embedded systems.

Key Features

• Density & Organization — 512 Mbit capacity (64M × 8) organized as 65,536 KByte with 262,144 programmable pages of 256 bytes each.
• Serial SPI Interface & Modes — Standard, Dual and Quad SPI support with standard SPI pins (CLK, CS#, DI, DO) and additional quad I/O lines for higher throughput; default Quad Enable (QE=1).
• High-Speed Read — Supports 104 MHz clock rate for Single/Dual/Quad I/O Fast Read and up to 133 MHz for Quad I/O Fast Read for accelerated code fetch and data access.
• Uniform Sector Architecture — 16,384 sectors of 4-Kbyte, 2,048 blocks of 32-Kbyte and 1,024 blocks of 64-Kbyte enabling selective sector or block erase operations.
• Fast Program & Erase — Typical page program time 0.5 ms; sector erase ~40 ms; half-block and block erase times and chip erase supported for flexible maintenance.
• Write Protection & Security — Software and hardware write-protect features, lockable 3 × 512-byte OTP security sector, and volatile status register bits for controlled memory protection.
• Low Power & Reliability — Typical active current ~14 mA and typical power-down current ~2 µA; minimum 100K program/erase cycles endurance and 20-year data retention.
• Voltage & Temperature Range — Full voltage range 1.65–1.95 V with industrial operating temperature range −40 °C to 85 °C.
• Package & Mounting — Surface-mount 16-pin SOP (300 mil) option suitable for compact board designs; Pb-free packages compliant with RoHS and Halogen-Free/REACH declarations.

Typical Applications

• Firmware & Boot Storage — Reliable non-volatile storage for system boot code and firmware images with support for in-field updates and selective block protection.
• Embedded Industrial Systems — Industrial-grade temperature range and robust endurance for control units, IoT gateways and other embedded equipment requiring long-term data retention.
• Code Patching & Modular Updates — Uniform sector architecture and software write-protect features enable safe, granular code patching without exposing remaining memory contents to accidental modification.

Unique Advantages

• High-density capacity: 512 Mbit in a compact 16-pin SOP package reduces board-level BOM and supports larger firmware or data sets without external memory expansion.
• Flexible performance modes: Single/Dual/Quad SPI operation and fast read clock rates (104/133 MHz) provide scalable throughput for different system bandwidth needs.
• Granular erase control: Uniform 4 KB sectors and multiple block sizes allow targeted erase operations, minimizing downtime during updates and preserving unchanged data.
• Designed for reliability: Minimum 100K erase/program cycles and 20-year data retention give confidence for long-life industrial deployments.
• Low power footprint: Typical 2 µA power-down current helps reduce standby power in battery-backed or energy-conscious systems.
• Hardware and software protection: Multiple protection mechanisms, including lockable OTP and write-protect modes, help secure critical code and data regions.
