EN35SXR512A-133HIP(2PC)

The EN35SXR512A-133HIP(2PC) is a serial SPI NOR flash memory device designed for industrial-grade embedded storage. It provides high-density non-volatile storage in a serial SPI architecture with Quad I/O support and uniform 4-Kbyte sectors for flexible code and data management.

This device targets applications that require reliable, long-term data retention and field-updatable code, combining high read throughput (up to 133 MHz Quad I/O Fast Read) with durable program/erase endurance and industrial temperature operation.

Key Features

• Memory Capacity and Organization — 512 M-bit total capacity implemented as 64M × 8 organization, with 256-byte programmable pages and 4-Kbyte uniform sectors for fine-grained erase and update.
• Serial SPI Interface — Supports Standard, Dual and Quad SPI modes with SPI-compatible signaling (Mode 0 and Mode 3) and selectable 3-byte/4-byte addressing.
• High-speed Read — Quad I/O Fast Read up to 133 MHz and Single/Dual/Quad Fast Read up to 104 MHz for accelerated code execute-in-place and data transfers.
• 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 seconds.
• Reliability and Endurance — Minimum 100K program/erase cycles per sector/block and data retention specified at 20 years.
• Power and Low-power Modes — Single power-supply operation with low power consumption characteristics: typical active current ~24 mA and typical power-down current ~2 µA as documented for the series.
• Security and Management — Lockable 3 × 512-byte OTP security sector, Read Unique ID, Replay-Protected Monotonic Counter (RPMC), and support for Serial Flash Discoverable Parameters (SFDP).
• Package and Temperature — Available in an 8-pin SOP 200 mil package; industrial operating temperature range −40 °C to 85 °C and surface-mount mounting type.
• Write Protection — Software and hardware write protection mechanisms with WP# and HOLD# signals to enable/disable protection and prevent accidental modification.
• Standards and Compliance — Pb-free packages compliant with RoHS and REACH declarations as provided for the series.

Typical Applications

• Embedded Firmware Storage — Reliable non-volatile storage for boot code, firmware images and in-field updates using sector/block erase and page program capabilities.
• Consumer and Industrial Control — Suitable for configuration storage and code execution in industrial controllers and consumer devices operating across the industrial temperature range.
• Data Logging and Secure Storage — Use the lockable OTP sector and RPMC for secure counters, unique ID-based authentication, and tamper-resistant small-data storage.
• Memory Expansion for MCUs — Adds high-density serial storage via Single/Dual/Quad SPI interfaces to microcontroller-based systems requiring fast read throughput.

Unique Advantages

• High-density serial storage: 512 M-bit capacity in a compact 8-pin SOP package provides substantial non-volatile space without large PCB footprint.
• Flexible I/O modes: Standard, Dual and Quad SPI support lets designers trade off pin usage and throughput to match system requirements.
• Field update and protection: Uniform 4-Kbyte sectors and software/hardware protection enable safe, granular updates to code and data segments.
• Industrial robustness: Specified operation from −40 °C to 85 °C and durable endurance/data-retention targets make it suitable for long-life deployments.
• Security features: Built-in OTP sector, unique ID and RPMC provide mechanisms for secure storage and anti-replay functionality.
