The MB9AF114LA is highly integrated 32-bit microcontrollers that target for high-performance and cost-sensitive embedded control applications. The MB9AF114LA is based on the ARM Cortex-M3 Processor with on-chip Flash memory and SRAM, and have peripheral functions such as Motor Control Timers, ADCs and Communication Interfaces (UART, CSIO, I2C, LIN).
- 32-bit ARM Cortex-M3 Core
- Processor version: r2p1
- Up to 40MHz Frequency Operation
- 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
- SRAM
- Multi-function Serial Interface (Max 8channels)
- DMA Controller (8channels) – The DMA Controller has an independent bus from the CPU, so CPU and DMA Controller can process simultaneously
