Overview of EN35QYR256A-104FIP(2UC) – 256 Mbit SPI NOR Flash (16-pin SOP 300mil)

The EN35QYR256A-104FIP(2UC) is a 256 Mbit serial SPI NOR Flash memory device optimized for embedded and industrial applications. It implements a serial interface with support for Standard, Dual and Quad I/O, delivering high-speed read access and flexible program/erase options.

Designed for firmware and data storage, the device combines a 104 MHz fast-read capability, uniform 4 Kbyte sector architecture and industrial temperature operation to support robust, field-deployed systems that require reliable non-volatile storage and in-field updates.

Key Features

  • Memory 256 M-bit capacity (organized as 32M × 8, 131,072 pages with 256 bytes per programmable page) and uniform 4 Kbyte sector architecture for predictable erase/program operations.
  • Interface SPI serial interface with Standard, Dual and Quad I/O (CLK, CS#, DI/DO, DQ₂, DQ₃). Supports SPI modes 0 and 3 and configurable dummy cycle number.
  • Performance Fast read at up to 104 MHz for Single/Dual/Quad I/O; typical page program time 0.5 ms and sector erase time 40 ms for responsive code and data updates.
  • Power Single power-supply operation (2.7–3.6 V). Low-power behavior includes typical active current of 12 mA and typical power-down current of 1 µA.
  • Reliability & Security Minimum 100K program/erase cycles per sector/block and >20-year data retention. Includes lockable 3×512 byte OTP security sector, Read Unique ID, and a Replay-Protected Monotonic Counter (RPMC).
  • Flexible Erase & Protection Uniform sector/block architecture with 4Kbyte sectors, 32Kbyte and 64Kbyte blocks; any sector or block can be erased individually. Software and hardware write protection options available.
  • Addressing & Compatibility Supports 3-byte and 4-byte address modes, and Serial Flash Discoverable Parameters (SFDP) signature for device interoperability.
  • Package & Temperature 16-pin SOP 300 mil package option and industrial temperature range (−40 °C to +85 °C).

Typical Applications

  • Embedded Systems & Firmware Storage — Reliable on-board storage for boot code, firmware images and field updates with uniform sectors for targeted reprogramming.
  • Industrial Control — Industrial temperature range and robust erase/program endurance suit controllers and instrumentation requiring dependable non-volatile memory.
  • Consumer & IoT Devices — High-speed SPI read and low-power standby characteristics enable responsive user interfaces and long battery life modes.
  • Secure Data Storage — Lockable OTP sector and unique ID/RPMC features support basic device authentication and protected counters for secure applications.

Unique Advantages

  • High-speed SPI Read: 104 MHz Single/Dual/Quad I/O Fast Read provides fast code and data fetch for latency-sensitive applications.
  • Granular Erase Control: Uniform 4 Kbyte sectors and multiple block sizes allow targeted erase operations, minimizing wear and reducing update times.
  • Low-power Standby: 1 µA typical power-down current preserves system power when the device is idle.
  • Industrial-ready: Specified operation from −40 °C to +85 °C supports deployment in harsh environments.
  • Endurance & Data Retention: Designed for a minimum of 100K program/erase cycles per sector/block with more than 20 years of data retention for long-term reliability.
  • Security & Device Identity: Lockable OTP region, Read Unique ID and RPMC support device-level protection and anti-replay use cases.
