MB9B360R Series
32-Bit ARM® Cortex® - M4F
FM4 Microcontroller
The MB9B360R Series are a highly integrated 32-bit microcontrollers dedicated for embedded controllers with high-performance
and competitive cost.
These series are based on the ARM® Cortex®-M4F Processor with on-chip Flash memory and SRAM, and has peripheral functions
such as Motor Control Timers, ADCs and Communication Interfaces (USB, UART, CSIO, I2C, LIN).
Features
32-bit ARM® Cortex®-M4F Core
ï®Processor version: r2p1
ï®Up to 160 MHz Frequency Operation
ï®FPU built-in
ï®Support DSP instruction
ï®Memory Protection Unit (MPU): improves the reliability of an
embedded system
ï®Integrated Nested Vectored Interrupt Controller (NVIC): 1
NMI (non-maskable interrupt) and 128 peripheral interrupts
and 16 priority levels
ï®24-bit System timer (Sys Tick): System timer for OS task
management
On-chip Memories
[Flash memory]
These series are based on two independent on-chip Flash
memories.
ï®MainFlash memory
ï¯ Up to 1024 Kbytes
ï¯ Built-in Flash Accelerator System with 16 Kbytes trace
buffer memory
ï¯ The read access to Flash memory can be achieved without
wait-cycle up to operation frequency of 72 MHz. Even at
the operation frequency more than 72 MHz, an equivalent
access to Flash memory can be obtained by Flash
Accelerator System.
ï¯ Security function for code protection
ï®WorkFlash memory
ï¯ 32 Kbytes
ï¯ Read cycle:
⢠6wait-cycle: the operation frequency more than 120 MHz,
and up to 160 MHz
⢠4wait-cycle: the operation frequency more than 72 MHz,
and up to 120 MHz
⢠2wait-cycle: the operation frequency more than 40 MHz,
and up to 72 MHz
⢠0wait-cycle: the operation frequency up to 40MHz
ï¯ Security function is shared with code protection
[SRAM]
This is composed of three independent SRAMs (SRAM0,
SRAM1 and SRAM2). SRAM0 is connected to I-code bus or
D-code bus of Cortex-M4F core. SRAM1 and SRAM2 are
connected to System bus of Cortex-M4F core.
ï®SRAM0: Up to 64 Kbytes
ï®SRAM1: Up to 32 Kbytes
ï®SRAM2: Up to 32 Kbytes
External Bus Interface
ï®Supports SRAM, NOR, NAND Flash and SDRAM device
ï®Up to 9 chip selects CS0 to CS8 (CS8 is only for SDRAM)
ï®8/16-bit Data width
ï®Up to 25-bit Address bit
ï®Supports Address/Data multiplex
ï®Supports external RDY function
ï®Supports scramble function
ï®Possible to set the validity/invalidity of the scramble function
for the external areas 0x6000_0000 to 0xDFFF_FFFF in 4
Mbytes units.
ï®Possible to set two kinds of the scramble key
Note: It is necessary to prepare the dedicated software
library to use the scramble function.
USB Interface
USB interface is composed of Function and Host.
[USB function]
ï®USB2.0 Full-Speed supported
ï®Max 6 EndPoint supported
ï¯ EndPoint 0 is control transfer
ï¯ EndPoint 1, 2 can be selected Bulk-transfer,
Interrupt-transfer or Isochronous-transfer
ï¯ EndPoint 3 to 5 can select Bulk-transfer or
Interrupt-transfer
ï¯ EndPoint 1 to 5 comprise Double Buffer
ï¯ The size of each endpoint is according to the follows.
⢠Endpoint 0, 2 to 5 : 64bytes
⢠Endpoint 1 : 256bytes
