MB9A310K Series 32-bit ARM Cortex -M3 FM3 Microcontroller The MB9A310K Series are a highly integrated 32-bit microcontrollers dedicated for embedded controllers with high-performance and low cost. These series are based on the ARM Cortex -M3 Processor with on-chip Flash memory and SRAM, and has peripheral functions 2 such as Motor Control Timers, ADCs and Communication Interfaces (USB, UART, CSIO, I C, LIN). The products which are described in this Datasheet are placed into TYPE5 product categories inFM3 Family Peripheral Manua. Features 32-bit ARM Cortex-M3 Core USB device Processor version: r2p1 USB2.0 Full-Speed supported Up to 40MHz Frequency Operation Max 6 EndPoint supported EndPoint 0 is control transfer Integrated Nested Vectored Interrupt Controller (NVIC): 1 EndPoint 1, 2 can be selected Bulk-transfer, Interrupt- NMI (non-maskable interrupt) and 48 peripheral interrupts transfer or Isochronous-transfer and 16 priority levels EndPoint 3 to 5 can be selected Bulk-transfer or Interrupt- transfer 24-bit System timer (Sys Tick): System timer for OS task management EndPoint 1 to 5 is comprised Double Buffer The size of each EndPoint is as follows. On-chip Memories EndPoint 0, 2 to 5: 64 bytes EndPoint 1: 256 bytes Flash memory This Series are based on two independent on-chip Flash USB host memories. USB2.0 Full/Low-speed supported MainFlash Bulk-transfer, interrupt-transfer and Isochronous-transfer Up to 128Kbyte support Read cycle: 0 wait-cycle Security function for code protection USB Device connected/dis-connected automatically detect WorkFlash IN/OUT token handshake packet automatically 32Kbyte Max 256-byte packet-length supported Read cycle: 0 wait-cycle Security function is shared with code protection Wake-up function supported SRAM Multi-function Serial Interface (Max 4 channels) This Series contain a total of up to 16Kbyte on-chip SRAM. 2 channels with 16-steps 9-bits FIFO (ch.0, ch.1), 2 This is composed of two independent SRAM (SRAM0, channels without FIFO (ch.3, ch.5) SRAM1) . SRAM0 is connected to I-code bus and D-code bus of Cortex-M3 core. SRAM1 is connected to System bus. Operation mode is selectable from the followings for each channel. SRAM0: 8 Kbyte (In ch.5, only UART and LIN are available.) SRAM1: 8 Kbyte UART CSIO USB Interface LIN 2 USB interface is composed of Device and Host. I C PLL for USB is built-in, USB clock can be generated by multiplication of Main clock.
