EN35QYR256A-104YIP(2UC)

The EN35QYR256A-104YIP(2UC) from ESMT is a 256 Mbit serial NOR flash memory device optimized for industrial embedded storage. It implements a serial SPI architecture with Single/Dual/Quad I/O support and a Fast Read clock rate of 104 MHz, delivering high-throughput code and data storage for industrial applications.

Designed for field-upgradeable firmware, secure data regions and long-term retention, this device combines uniform 4 KB sectors and robust program/erase endurance with low-power standby modes to support reliable operation across -40 °C to 85 °C.

Key Features

• Memory Capacity & Organization — 256 Mbit (32,768 KByte) organized as 32M × 8 with 131,072 pages and 256 bytes per programmable page; 8,192 uniform 4-Kbyte sectors for granular erase and update.
• SPI Serial Interface — Serial SPI-compatible architecture supporting Standard, Dual and Quad SPI modes (CLK, CS#, DI, DO and DQ0–DQ3) for flexible performance and pin-efficient designs.
• High-Speed Read — Fast Read operation at a 104 MHz clock rate for Single/Dual/Quad I/O to accelerate 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 and block erase options for efficient memory management.
• Power — Low active and standby draw with typical active current around 12 mA and power-down current near 1 µA for energy-conscious systems.
• Security & Management — Software and hardware write protection, lockable 3×512-byte OTP security sector, Read Unique ID and a Replay-Protected Monotonic Counter (RPMC).
• Durability & Retention — Minimum 100K program/erase cycles per sector/block and greater than 20-year data retention for long-life deployments.
• Voltage & Package — Single-supply serial flash with full voltage range 2.7–3.6 V (3 V class); available in industrial-grade 8-pin WSON 8×6 mm surface-mount package.
• Temperature Grade & Compliance — Industrial temperature range −40 °C to 85 °C and RoHS-compliant packaging.

Typical Applications

• Embedded Firmware Storage — Reliable non-volatile storage for boot code and firmware in industrial controllers and embedded appliances, with support for sector-level updates and protection.
• Field Upgradeable Systems — Remote firmware updates and code patching using uniform 4 KB sectors and software/hardware write-protect features to isolate updated regions.
• Industrial Automation — Program and parameter storage for PLCs, motor controllers and factory equipment operating across industrial temperature ranges.
• Communications & Networking Equipment — Storage of boot images, configuration data and device IDs where fast read access (104 MHz) and unique ID/RPMC capability are required.

Unique Advantages

• Flexible I/O Modes: Single, Dual and Quad SPI support lets designers scale throughput without changing core memory topology.
• Granular Erase Architecture: 4 KB uniform sectors and multiple block sizes enable targeted updates and minimize erase times for localized code/data changes.
• Fast Program & Erase: Typical page program in 0.5 ms and sector erase in 40 ms help reduce system downtime during updates.
• Low Power Operation: Typical 12 mA active and ~1 µA power-down currents help minimize energy use in battery-backed or low-power industrial systems.
• Long-Term Reliability: Specified minimum 100K program/erase cycles and more than 20 years of data retention support long product lifecycles.
• Industrial-Grade Packaging: Surface-mount 8-pin WSON 8×6 mm package rated for −40 °C to 85 °C simplifies integration into rugged PCBs.
