Infineon/CYPRESS CY9BF566LQN-G-AVE2

Series are highly integrated 32-bit microcontrollers with high performance and competitive cos. This series is based on the Arm Cortex-M4F Processor with on-chip Flash memory and SRAM. The series has periph functions such as Motor Control Timers, ADCs and Communication Interfaces (USB, CAN, UART, CSIO, I2C, LIN).

• 32-bit Arm® Cortex®-M4F Core
  • Processor version: r0p1
  • Up to 160 MHz Frequency Operation
  • FPU built-in
  • Support DSP instruction
  • Memory Protection Unit (MPU): improves the reliability of an embedded system
  • Integrated Nested Vectored Interrupt Controller (NVIC): 1 NMI (non-maskable interrupt) and 128 peripheral interrupts and 16 priority levels
  • 24-bit System timer (Sys Tick): System timer for OS task management
• On-Chip Memories
  • [Flash Memory]
    • Based on two independent on-chip Flash memories
    • MainFlash memory
      • Up to 512 Kbytes
      • Built-in Flash Accelerator System with 16 Kbytes trace buffer memory
      • The read access to Flash memory can be achieved without wait-cycle up to operation frequency of 72 MHz. Even at the operation frequency more than 72 MHz, an equivalent access to Flash memory can be obtained by Flash Accelerator System.
      • Security function for code protection
        • 6wait-cycle: the operation frequency more than 120 MHz, and up to 160 MHz
        • 4wait-cycle: the operation frequency more than 72 MHz, and up to 120 MHz
        • 2wait-cycle: the operation frequency more than 40 MHz, and up to 72 MHz
        • 0wait-cycle: the operation frequency up to 40 MHz
      • Security function is shared with code protection
  • [SRAM]
    • Composed of three independent SRAMs (SRAM0, SRAM1, and SRAM2). SRAM0 is connected to I-code bus and D-code bus of Cortex-M4F core. SRAM1 and SRAM2 are connected to System bus of Cortex-M4F core.
    • SRAM0: Up to 32 Kbytes
    • SRAM1: Up to 16 Kbytes
    • SRAM2: Up to 16 Kbytes
