MB9B160R Series
32-Bit ARM^® Cortex^®-M4F
FM4 Microcontroller
The MB9B160R 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 (UART, CSIO, I²C, LIN).
Features
32-bit ARM^® Cortex^®-M4F Core
Processor version: r2p1
Up to 160 MHz Frequency Operation
FPU built-in
Support DSP instruction
Memory Protection Unit (MPU): improves the reliability of an
embedded system
Integrated Nested Vectored Interrupt Controller (NVIC): 1
NMI (non-maskable interrupt) and 128 peripheral interrupts
and 16 priority levels
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.
MainFlash memory
 Up to 1024 Kbytes
 Built-in Flash Accelerator System with 16 Kbytes trace
buffer memory
 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.
 Security function for code protection
WorkFlash memory
 32 Kbytes
 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
 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.
SRAM0: Up to 64 Kbytes
SRAM1: Up to 32 Kbytes
SRAM2: Up to 32 Kbytes
External Bus Interface
Supports SRAM, NOR, NAND Flash and SDRAM device
Up to 9 chip selects CS0 to CS8 (CS8 is only for SDRAM)
8/16-bit Data width
Up to 25-bit Address bit
Supports Address/Data multiplex
Supports external RDY function
Supports scramble function
Possible to set the validity/invalidity of the scramble function
for the external areas 0x6000_0000 to 0xDFFF_FFFF in 4
Mbytes units.
Possible to set two kinds of the scramble key
Note: It is necessary to prepare the dedicated software
library to use the scramble function.
Multi-function Serial Interface (Max 8 channels)
64 bytes with FIFO (the FIFO step numbers are variable
depending on the settings of the communication mode or bit
length.)
Operation mode is selectable from the followings for each
channel.
 UART
 CSIO
 LIN
 I²C
