EN35SXR64A-104XDIP(2UC)

The EN35SXR64A-104XDIP(2UC) is a 64 M-bit serial SPI NOR flash memory device designed for single-supply operation. It provides a uniform 4 Kbyte sector architecture and supports Standard, Dual and Quad SPI I/O to deliver high-bandwidth read performance up to a 104 MHz clock rate.

Engineered for industrial environments, the device combines fast read throughput, low-power standby behavior and robust program/erase endurance, making it suitable for firmware storage, code shadowing, and data logging in embedded and industrial systems.

Key Features

• Core / Memory 64 M-bit (8,192 KByte) density arranged as 32,768 pages of 256 bytes each; uniform 4 Kbyte sectors for flexible erase and update management.
• Performance Fast read operation up to 104 MHz for Single/Dual/Quad I/O Fast Read; typical active current around 8 mA supporting efficient system operation.
• Program & Erase Page program time typically 0.5 ms; sector erase typically 40 ms; block and chip erase options with documented typical times for predictable update windows.
• Interface SPI-compatible serial interface supporting Standard (CLK, CS#, DI, DO), Dual (DQ0/DQ1) and Quad (DQ0–DQ3) modes; supports SPI Mode 0 and Mode 3.
• Power Single power supply operation with full voltage range 1.65–1.95 V and typical ultra-low power down current (~0.1 µA) for long-term standby.
• Security & Reliability Software and hardware write protection, lockable 3×512 byte OTP security sector, Read Unique ID and Replay‑Protected Monotonic Counter (RPMC); minimum 100K program/erase endurance and >20‑year data retention.
• Package & Temperature 8‑lead USON package (4.00 × 4.00 × 0.55 mm) for surface-mount assembly; industrial temperature range −40 °C to +85 °C and RoHS compliant.

Typical Applications

• Embedded Firmware Storage — Store boot code, firmware images and configuration data with sector-level erase flexibility and field update support.
• Industrial Control — Non-volatile code and data storage for PLCs, HMIs and industrial communication modules operating across −40 °C to +85 °C.
• Consumer & IoT Devices — Hold application code, parameter tables and OTA update images where low power and high-speed read access are required.
• Secure Data and Counters — Use built-in OTP and RPMC features to protect small secure data regions and monotonic counters for device integrity functions.

Unique Advantages

• High-speed Serial Read: 104 MHz Single/Dual/Quad Fast Read increases throughput for code shadowing and fast boot sequences.
• Flexible SPI Modes: Standard, Dual and Quad I/O support lets designers scale interface bandwidth without changing memory architecture.
• Granular Erase Control: 4 Kbyte uniform sectors and multiple block sizes enable targeted updates and reduced erase overhead.
• Low Power Standby: Sub-microamp power-down current minimizes energy draw in sleep modes for battery-backed systems.
• Industrial Reliability: Rated for −40 °C to +85 °C and a documented minimum of 100K program/erase cycles per sector for long service life.
• Security Primitives: OTP sector, unique ID and RPMC provide hardware-level primitives useful for device authentication and secure counters.
