لوحة Teensy 4.0 Lockable هي لوحة تطوير عالية الأداء تعتمد على معالج ARM Cortex-M7 بسرعة 600 ميجاهرتز. صُممت للاستخدام التجاري والإنتاجي، وتوفر نظام حماية دائم للبرمجيات عبر فيوز أمني يُبرمج مرة واحدة. بذاكرة 1MB RAM و2MB Flash، إضافة إلى مجموعة واسعة من المنافذ، تقدم اللوحة سرعة استثنائية وأداءً آنياً مع حماية كاملة للملكية الفكرية، ضمن حجم صغير مناسب للتجارب والتطبيقات الاحترافية.
The Teensy 4.0 Lockable is a compact yet extremely powerful microcontroller board built around the NXP MIMXRT1062 ARM Cortex-M7 processor running at 600 MHz. It belongs to the “Crossover MCU” category, combining real-time responsiveness with application-level performance.
This lockable version is specifically intended for finalized products, allowing developers to permanently secure their firmware using programmable eFuses. Once locked, the code is encrypted, JTAG debugging is disabled, and only authorized firmware can run on the device, ensuring complete IP protection.
With advanced memory architecture using Tightly Coupled Memory (TCM), hardware floating-point support, cryptographic acceleration, and rich high-speed peripherals, the Teensy 4.0 Lockable is ideal for demanding, security-critical embedded applications.
