MB9AB40NB Series 32-bit ARM Cortex -M3 FM3 Microcontroller The MB9AB40NB 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 2 peripheral functions such as various timers, ADCs, LCDC and Communication Interfaces (USB, UART, CSIO, I C). The products which are described in this data sheet are placed into TYPE6 product categories in FM3 Family Peripheral Manual. Features 32-bit ARM Cortex-M3 Core USB Interface Processor version: r2p1 The USB interface is composed of Device and Host. PLL for USB is built-in, USB clock can be generated by multiplication Up to 40 MHz Frequency Operation of Main clock. Integrated Nested Vectored Interrupt Controller (NVIC): 1 NMI (non-maskable interrupt) and USB device 48 peripheral interrupts and 16 priority levels USB2.0 Full-Speed supported 24-bit System timer (Sys Tick): System timer for OS task Max 6 EndPoint supported management EndPoint 0 is control transfer EndPoint 1, 2 can select Bulk-transfer, On-chip Memories Interrupt-transfer or Isochronous-transfer EndPoint 3 to 5 can select Bulk-transfer or Flash memory Interrupt-transfer Dual operation Flash memory EndPoint 1 to 5 is comprised of Double Buffers. Dual Operation Flash memory has the upper bank and The size of each endpoint is according to the follows. the lower bank. So, this series could implement erase, Endpoint 0, 2 to 5: 64 bytes write and read operations for each bank Endpoint 1: 256 bytes simultaneously. Main area: Up to 256 Kbytes (Up to 240 Kbytes upper USB host bank + 16 Kbytes lower bank) USB2.0 Full/Low-speed supported Work area: 32 Kbytes (lower bank) Bulk-transfer, interrupt-transfer and Isochronous-transfer Read cycle: 0 wait-cycle support Security function for code protection USB Device connected/disconnected automatic detection SRAM Automatic processing of the IN/OUT token handshake packet This Series on-chip SRAM is composed of two independent 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 Wake-up function supported System bus. SRAM0: Up to 16 Kbytes LCD Controller (LCDC) SRAM1: Up to 16 Kbytes Up to 40 SEG 8 COM 8 COM or 4 COM mode can be selected. External Bus Interface* Built-in internal dividing resistor Supports SRAM, NOR Flash memory device LCD drive power supply (bias) pin (VV4 to VV0) Up to 8 chip selects With blinking function 8-/16-bit Data width Up to 25-bit Address bit Maximum area size : Up to 256 Mbytes Supports Address/Data multiplex Supports external RDY function *: MB9AFB41LB, FB42LB and FB44LB do not support External Bus Interface.
