MB9B320M Series 32-bit Arm Cortex -M3 FM3 Microcontroller The MB9B320M Series are highly integrated 32-bit microcontrollers dedicated for embedded controllers with low-power consumption mode and competitive cost. These series are based on the Arm Cortex -M3 Processor with on-chip Flash memory and SRAM, and have peripheral functions 2 such as various timers, ADCs, DACs and Communication Interfaces (USB, UART, CSIO, I C, LIN). The products which are described in this data sheet are placed into TYPE9 product categories in FM3 Family Peripheral Manual. Features USB device 32-bit Arm Cortex -M3 Core USB2.0 Full-Speed supported Processor version: r2p1 Max 6 EndPoint supported Up to 72 MHz Frequency Operation EndPoint 0 is control transfer Integrated Nested Vectored Interrupt Controller (NVIC): 1 EndPoint 1, 2 can select Bulk-transfer, Interrupt-transfer or NMI (non-maskable interrupt) and 48 peripheral interrupts Isochronous-transfer and 16 priority levels EndPoint 3 to 5 can select Bulk-transfer or Interrupt-transfer 24-bit System timer (Sys Tick): System timer for OS task EndPoint 1 to 5 are comprised of Double Buffers. management The size of each endpoint is according to the follows. Endpoint 0, 2 to 5: 64bytes On-chip Memories Endpoint 1: 256bytes Flash memory USB host Dual operation Flash memory USB2.0 Full/Low-speed supported Dual Operation Flash memory has the upper bank and the lower bank. Bulk-transfer, interrupt-transfer and Isochronous-transfer So, this series could implement erase, write and read support operations for each bank simultaneously. Main area: Up to 256 Kbytes (Up to 240 Kbytes upper bank USB Device connected/dis-connected automatic detection + 16 Kbytes lower bank) Automatic processing of the IN/OUT token handshake Work area: 32 Kbytes (lower bank) packet Read cycle: 0 wait-cycle Max 256-byte packet-length supported Security function for code protection Wake-up function supported SRAM This Series on-chip SRAM is composed of two independent Multi-function Serial Interface (Max eight channels) SRAM (SRAM0, SRAM1). SRAM0 is connected to I-code bus 4 channels with 16 steps9-bit FIFO (ch.0/1/3/4), 4 channels and D-code bus of Cortex-M3 core. SRAM1 is connected to without FIFO (ch.2/5/6/7) System bus. Operation mode is selectable from the followings for each SRAM0: Up to 16 Kbytes channel. SRAM1: Up to 16 Kbytes UART CSIO USB Interface LIN 2 The 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.
