EN35QY512A-133HIP(2S)

The EN35QY512A-133HIP(2S) is a 512 Mbit serial NOR Flash memory device from ESMT designed for industrial embedded storage of code and data. It implements a SPI-compatible serial architecture with Single, Dual and Quad I/O modes and a Quad I/O Fast Read clock of up to 133 MHz for high-throughput code and data retrieval.

With uniform 4-Kbyte sectors, fast program/erase performance and industrial temperature range, the device targets firmware storage, in-field updates and non-volatile data retention in space- or power-constrained embedded systems.

Key Features

• Memory 512 M-bit (64M × 8) serial Flash memory organized as 65,536 KByte with 256-byte programmable pages and 4-Kbyte uniform sectors (16,384 sectors).
• Performance Quad I/O Fast Read up to 133 MHz and Single/Dual/Quad Fast Read up to 104 MHz; typical page program time 0.5 ms and typical sector erase time 40 ms.
• Interface Serial Peripheral Interface (SPI) compatible with Standard, Dual and Quad SPI command sets; supports 3-byte and 4-byte addressing and configurable dummy cycles.
• Power Single-supply operation across the device’s specified voltage range (2.7–3.6 V) with typical active current around 14 mA and typical power-down current around 2 μA.
• Reliability & Endurance Minimum 100K program/erase cycles per sector and guaranteed data retention of 20 years.
• Protection & Security Software and hardware write protection with WP# pin, lockable 3 × 512-byte OTP security sector, and support for Serial Flash Discoverable Parameters (SFDP) and Unique ID readout.
• Package & Temperature Offered in compact Pb‑free packages including 8‑lead SOP (200 mil), 16‑lead SOP (300 mil) and VDFN/WSON options; rated for industrial operation from −40 °C to 85 °C.

Typical Applications

• Embedded Systems Non-volatile storage for boot code, firmware images and configuration data where fast read performance and in-field updates are required.
• Industrial Control Firmware and parameter storage for controllers and instrumentation operating across the industrial temperature range.
• Networking & Edge Appliances Storage for firmware and device configuration in appliances and gateways that benefit from Quad I/O read bandwidth and low standby power.
• Consumer & IoT Devices External code and data storage for devices requiring compact, surface-mount packaging and secure, lockable memory regions.

Unique Advantages

• High-bandwidth Quad I/O: Quad I/O Fast Read up to 133 MHz delivers significantly faster read throughput for code- and data-fetch operations.
• Uniform 4 KB Sectors: 16,384 uniform sectors simplify block management for firmware updates and partial-chip erase operations.
• Robust Endurance and Retention: Minimum 100K program/erase cycles and 20-year data retention support long-life deployments and field-upgrade cycles.
• Flexible Protection: Combined hardware (WP#) and software write protection plus a lockable OTP region enable secure storage of critical data and code.
• Industrial Temperature Range: Specified −40 °C to 85 °C for reliable operation in demanding environments.
• Compact, Pb‑free Packages: Multiple surface-mount package options fit a wide range of PCB space and assembly requirements.
