MB9B520TA Series 32-bit Arm Cortex -M3 FM3 Microcontroller The MB9B520TA 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, CAN, UART, CSIO, I C, LIN). The products which are described in this data sheet are placed into TYPE12 product categories in FM3 Family Peripheral Manual. Features 32-bit Arm Cortex -M3 Core USB Interface The USB interface is composed of Device and Host. Processor version: r2p1 PLL for USB is built-in, USB clock can be generated by multiplication of Main clock. Up to 60 MHz Frequency Operation Integrated Nested Vectored Interrupt Controller (NVIC): 1 USB Device NMI (non-maskable interrupt) and 48 peripheral interrupts USB2.0 Full-Speed supported and 16 priority levels Max 6 EndPoint supported 24-bit System timer (Sys Tick): System timer for OS task EndPoint 0 is control transfer management EndPoint 1, 2 can select Bulk-transfer, Interrupt-transfer or Isochronous-transfer On-chip Memories EndPoint 3 to 5 can select Bulk-transfer or Interrupt-transfer Flash memory EndPoint 1 to 5 are comprised of Double Buffers. Dual operation Flash memory The size of each Endpoint is as follows. Main area: Endpoint 0, 2 to 5: 64 bytes Up to 1.5 Mbytes (1008 Kbytes (ROM0) + Endpoint 1: 256 bytes 512 Kbytes (ROM1) of Upper bank and USB host 16 Kbytes (ROM0) of Lower bank) Work area: USB2.0 Full/Low-speed supported 64 Kbytes (ROM1) of Lower bank Bulk-transfer, interrupt-transfer and Isochronous-transfer Read cycle: 0 wait-cycle support Security function for code protection USB Device connected/dis-connected automatic detection SRAM Automatic processing of the IN/OUT token handshake This Series on-chip SRAM is composed of two independent packet SRAM (SRAM0, SRAM1). SRAM0 is connected to I-code bus Max 256-byte packet-length supported and D-code bus of Cortex-M3 core. SRAM1 is connected to System bus.
