EN35SY512A-104HIP(2PC)

The EN35SY512A-104HIP(2PC) is a 512 Mbit serial SPI NOR flash memory device designed for industrial temperature applications. It provides a serial SPI interface with support for Standard, Dual and Quad I/O modes, delivering high‑speed read access and flexible flash management for embedded and firmware storage needs.

Targeted at industrial and embedded systems, this device combines uniform sector architecture, fast read performance up to 104 MHz, and write/erase mechanisms that support field updates, secure regions and long data retention.

Key Features

• Memory Capacity & Organization — 512 Mbit capacity organized as 64M × 8 with 256‑byte programmable pages and 4 Kbyte uniform sectors for predictable erase and program granularity.
• Serial SPI Architecture — SPI compatible interface with Standard, Dual and Quad SPI support (CLK, CS#, DI/DO and DQ0–DQ3). Default quad enable and disabled WP#/HOLD# provide immediate quad I/O operation.
• High Read Performance — Fast Read operation at up to 104 MHz for Single/Dual/Quad I/O modes to accelerate code and data fetches in embedded systems.
• Program/Erase Performance — Typical page program time of 0.5 ms and sector erase time of 40 ms enable efficient in-field updates; chip erase and block/half‑block erase timings are documented for system planning.
• Low Power — Typical active current is 14 mA with a low power-down current of approximately 2 µA to help manage system power budgets.
• Reliability & Data Retention — Minimum 100k program/erase cycles per sector and typical data retention of 20 years for long-term storage of firmware and configuration data.
• Security & Identification — Lockable 3 × 512‑byte OTP security sector and Read Unique ID capability for device identification and basic secure storage.
• Voltage & Package — Surface-mount 8‑pin SOP (200 mil) package and documented supply voltage in product specifications; RoHS‑compliant Pb‑free packages are available.
• Industrial Temperature Range — Rated for operation from −40 °C to 85 °C for deployment in industrial environments.

Typical Applications

• Firmware and Boot Storage — Stores boot code and firmware images with fast read performance and sector-level protection for safe updates.
• Field Upgradeable Systems — Page program and sector erase timings support in-system firmware patching and over‑the‑air updates where selective block erase/program is required.
• Embedded and Industrial Control — Industrial temperature rating and low standby current make it suitable for controllers, PLCs and other embedded industrial devices.
• Device Identification & Secure Parameters — Read Unique ID and lockable OTP sectors enable device-level identification and protected parameter storage.

Unique Advantages

• Flexible SPI Modes: Standard, Dual and Quad SPI support provides designers options to scale read throughput without changing memory family.
• Uniform Sector Architecture: 4 Kbyte sectors with block and half‑block erase options simplify memory management and reduce erase overhead for targeted updates.
• Fast Read Clock: 104 MHz Fast Read capability reduces code fetch latency and improves system boot and runtime performance.
• Field-Proven Endurance: 100k program/erase cycle endurance and long data retention support long life cycles in industrial deployments.
• Low Power Standby: Typical 2 µA power-down current helps minimize energy use in battery‑assisted or low‑power designs.
• Industrial Temperature and SMD Package: −40 °C to 85 °C rating and 8‑pin SOP (200 mil) surface-mount packaging enable compact, robust board-level integration.
