The MB9BF566N is a highly integrated 32-bit microcontrollers dedicated for embedded controllers with high-performance and competitive cost.These series are based on the ARM Cortex-M4F Processor with on-chip Flash memory and SRAM, and has peripheral functions such as Motor Control Timers, ADCs and Communication Interfaces (USB, CAN, UART, CSIO, I2C, LIN).
- 32-bit ARM Cortex-M4F Core
- Processor version: r2p1
- 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] These series are based on two independent on-chip Flash memories.
- MainFlash memory
- Up to 1024 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
- WorkFlash memory
- 32 Kbytes
- Read cycle:
- 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 40MHz
- Security function is shared with code protection
- [SRAM]: This is composed of three independent SRAMs (SRAM0, SRAM1 and SRAM2). SRAM0 is connected to I-code bus or D-code bus of Cortex-M4F core. SRAM1 and SRAM2 are connected to System bus of Cortex-M4F core.
- SRAM0: Up to 64 Kbytes
- SRAM1: Up to 32 Kbytes
- SRAM2: Up to 32 Kbytes
- CAN Interface (Max 2 channels)
- Multi-function Serial Interface (Max 8 channels)
- 64 bytes with FIFO (the FIFO step numbers are variable depending on the settings of the communication mode or bit length.)
- Operation mode is selectable from the followings for each channel.
- UART
- CSIO
- LIN
- I2C
- DMA Controller (8 channels)
- A/D Converter (Max 24 channels)
