Technical Highlights
- Fast Read & XIP Capable: 70 ns access time with page‑mode read (16‑word page) enables zero‑wait‑state code execution directly from flash.
- CFI & JEDEC Standard: Common Flash Interface allows software to auto‑detect memory parameters, simplifying firmware development and platform migration.
- Industrial‑Grade Reliability: The "0SIT" suffix guarantees operation from –40°C to +85°C with enhanced data retention and endurance for demanding applications.
- Advanced Protection: Supports block lock/unlock, password protection, and volatile/non‑volatile protection bits to safeguard critical code.
