The MB9BF314N 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-M3 Processor with on-chip Flash memory and SRAM, and has peripheral functions such as Motor Control Timers, ADCs and Communication Interfaces (USB, UART, CSIO, I2C, LIN).
- 32-bit ARM Cortex-M3 Core
- Processor version: r2p1
- Up to 144MHz Frequency Operation
- Memory Protection Unit (MPU): improves the reliability of an embedded system
- Integrated Nested Vectored Interrupt Controller (NVIC): 1 NMI (non-maskable interrupt) and 48 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
- Up to 512Kbyte
- Built-in Flash Accelerator System with 16Kbyte trace buffer memory
- The read access to Flash memory can be achieved without wait cycle up to operation frequency of 72MHz. Even at the operation frequency more than 72MHz, an equivalent access to Flash memory can be obtained by Flash Accelerator System.
- Security function for code protection
- WorkFlash
- 32Kbyte
- Read cycle
- 4wait-cycle: the operation frequency more than 72MHz
- 2wait-cycle: the operation frequency more than 40MHz, and to 72MHz
- 0wait-cycle: the operation frequency to 40MHz
- Security function is shared with code protection
- [SRAM]: This Series contain a total of up to 64Kbyte on-chip SRAM memories. This is composed of two independent SRAM (SRAM0, SRAM1). SRAM0 is connected to I-code bus or D-code bus of Cortex-M3 core. SRAM1 is connected to System bus.
- SRAM0: Up to 32 Kbyte
- SRAM1: Up to 32 Kbyte
- External Bus Interface
- Supports SRAM, NOR and NAND Flash device
- Up to 8 chip selects
- 8/16-bit Data width
- Up to 25-bit Address bit
- Supports Address/Data multiplex
- Supports external RDY input
- A/D Converter (Max 16channels)
- DMA Controller (8channels)
- Base Timer (Max 8channels)
