These devices embed high-speed memory (512 KB Flash and 128 KBSRAM), a Flexible External Memory Controller (FSMC) for static memory (for devices with 100-pin and more packages), a Quad SPI flash interface, and a wide range of enhanced I/O and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

The device also embeds multiple protection mechanisms for embedded flash and SRAM: read protection, write protection, secure memory area, and proprietary code read protection.
