MB9B300B Series 32-bit Arm Cortex -M3 FM3 Microcontroller The MB9B300B Series are a highly integrated 32-bit microcontroller that target for high-performance and cost-sensitive embedded control applications. The MB9B300B Series are based on the Arm Cortex -M3 Processor and on-chip Flash memory and SRAM, and peripheral 2 functions, including Motor Control Timers, ADCs and Communication Interfaces (USB, UART, CSIO, I C, LIN). The products which are described in this datasheet are placed into TYPE0 product categories in FM3 Family Peripheral Manual. Features 32-bit Arm Cortex -M3 Core USB host Processor version: r2p0 USB2.0 Full/Low-speed supported Up to 80 MHz Frequency Operation Bulk-transfer and interrupt-transfer and Isochronous-transfer support Memory Protection Unit (MPU): improve the reliability of an embedded system USB Device connected/dis-connected automatically detect Integrated Nested Vectored Interrupt Controller (NVIC): 1 IN/OUT token handshake packet automatically NMI (non-maskable interrupt) and 48 peripheral interrupts Max 256-byte packet-length supported and 16 priority levels Wake-up function supported 24-bit System timer (Sys Tick): System timer for OS task management Multi-function Serial Interface (Max. 8 channels) On-chip Memories 4 channels with 16steps 9bit FIFO (ch.4-ch.7), 4 channels without FIFO (ch.0-ch.3) Flash memory Operation mode is selectable from the followings for each Up to 512 KB channel. 1 Read cycle: 0 wait-cycle up to 60 MHz, 2 wait-cycle UART above CSIO 1 : Instruction pre-fetch buffer is included. So when CPU LIN access continuously, it becomes 0 wait-cycle 2 I C Security function for code protection UART SRAM Full-duplex double buffer This series contain a total of up to 64 KB on-chip SRAM. This Selection with or without parity supported is composed of two independent SRAM (SRAM0, SRAM1). SRAM0 is connected to I-code bus and D-code bus of Cortex- Built-in dedicated baud rate generator M3 core. SRAM1 is connected to System bus. External clock available as a serial clock SRAM0: Up to 32 KB Hardware Flow control: Automatically control the SRAM1: Up to 32 KB transmission by CTS/RTS (only ch.4) Various error detect functions available (parity errors, USB Interface framing errors, and overrun errors) The USB interface is composed of Device and Host. PLL for USB is built-in, USB clock can be generated by CSIO multiplication of Main clock. Full-duplex double buffer USB Device Built-in dedicated baud rate generator USB2.0 Full-Speed supported Overrun error detect function available Max 6 EndPoint supported EndPoint 0 is control transfer EndPoint 1 - 5 can be selected bulk-transfer or interrupt- transfer Endpoint1-5 is comprised Double Buffers.
