• Program & Erase Speed — Page program time typically 0.5 ms (500 µs); sector erase typically 40 ms; half‑block and block erase and full chip erase times available per device specifications.
• Power & Voltage — Single‑supply operation over 2.7–3.6 V full voltage range; low power consumption with typical active current ≈14 mA and typical power‑down current ≈2 µA.
• Reliability & Retention — Minimum 100K program/erase cycles per sector and typical data retention of 20 years.
• Security & Protection — Software and hardware write protection, WP# pin and HOLD# pin support, lockable 3 × 512‑byte One‑Time Programmable (OTP) security sector, and volatile status register bits for protection control.
• Addressing & Standards — Supports 3‑byte and 4‑byte address modes and Serial Flash Discoverable Parameters (SFDP) signature; includes Read Unique ID command.
• Package & Temperature — Industrial‑grade device available in 8‑pin SOP (200 mil) package; operating temperature range −40 °C to 85 °C; surface‑mount mounting.
• Compliance — Pb‑free packages compliant with RoHS and related environmental directives.

Typical Applications

• Embedded Firmware Storage — Store and update bootloaders, firmware images and configuration data with sector‑level erase and write‑protect features for safe in‑field updates.
• Industrial Control Systems — Non‑volatile code and parameter storage for controllers and instrumentation operating across −40 °C to 85 °C.
• Consumer & IoT Devices — High‑density code and data storage for devices that require low power standby and fast SPI read performance.
• Secure ID & Configuration — Use the lockable OTP region and unique ID for device configuration, authentication tokens or calibration data.

Unique Advantages

• High Density in Compact Packages — 512 Mbit capacity in an 8‑pin SOP 200 mil package simplifies BOM and board area for space‑constrained designs.
• Flexible SPI Modes — Standard, Dual and Quad I/O support enables designers to scale throughput to match system performance targets.
• Fine‑Grained Erase and Protection — 4‑Kbyte uniform sectors and multiple protection mechanisms enable safe partial updates without exposing other code regions.
• Industrial Temperature Range — Specified −40 °C to 85 °C operation makes the device suitable for a wide range of industrial embedded applications.
• Proven Program/Erase Endurance and Retention — Minimum 100K cycles and 20‑year data retention provide long term reliability for stored code and key data.
• Low Power Standby — Typical 2 µA power‑down current helps reduce system standby power in battery‑sensitive designs.
