MB9B160L Series



Various error detect functions available (parity errors,

framing errors, and overrun errors)

I2C



Standard mode (Max 100 kbps) / High-speed mode (Max

400 kbps) supported



Fast mode Plus (Fm+) (Max 1000 kbps, only for ch.3=ch.A

and ch.4=ch.B) supported

DMA Controller (8 channels)

DMA Controller has an independent bus for CPU, so CPU and

DMA Controller can process simultaneously.

8 independently configured and operated channels

Transfer can be started by software or request from the

built-in peripherals

Transfer address area: 32-bit (4 Gbytes)

Transfer mode: Block transfer/Burst transfer/Demand

transfer

Transfer data type: bytes/half-word/word

Transfer block count: 1 to 16

Number of transfers: 1 to 65536

DSTC (Descriptor System data Transfer Controller)

(128 channels)

The DSTC can transfer data at high-speed without going via

the CPU. The DSTC adopts the Descriptor system and,

following the specified contents of the Descriptor which has

already been constructed on the memory, can access directly

the memory /peripheral device and performs the data transfer

operation.

It supports the software activation, the hardware activation and

the chain activation functions.

A/D Converter (Max 15 channels)

[12-bit A/D Converter]

Successive Approximation type

Built-in 2 units

Conversion time: 0.5 μs @ 5 V

Priority conversion available (priority at 2levels)

Scanning conversion mode

Built-in FIFO for conversion data storage (for SCAN

conversion: 16steps, for Priority conversion: 4steps)

DA Converter (Max 2 channels)

R-2R type

12-bit resolution

Base Timer (Max 8 channels)

Operation mode is selectable from the followings for each

channel.

16-bit PWM timer

16-bit PPG timer

16-/32-bit reload timer

16-/32-bit PWC timer

General Purpose I/O Port

This series can use its pins as general purpose I/O ports when

they are not used for external bus or peripherals. Moreover, the

port relocate function is built in. It can set which I/O port the

peripheral function can be allocated.

Capable of pull-up control per pin

Capable of reading pin level directly

Built-in the port relocate function

Up to 48 high-speed general-purpose I/O ports @ 64 pin

Package

Some pin is 5 V tolerant I/O.

See 4. Pin Description and 5. I/O Circuit Type for the

corresponding pins.

Multi-function Timer (Max 2 units)

The Multi-function timer is composed of the following blocks.

Minimum resolution: 6.25 ns

16-bit free-run timer × 3 ch./unit

Input capture × 4 ch./unit

Output compare × 6 ch./unit

A/D activation compare × 6 ch./unit

Waveform generator × 3 ch./unit

16-bit PPG timer × 3 ch./unit

The following function can be used to achieve the motor

control.

PWM signal output function

DC chopper waveform output function

Dead time function

Input capture function

A/D convertor activate function

DTIF (Motor emergency stop) interrupt function

Real-time clock (RTC)

The Real-time clock can count Year/Month/Day/Hour/Minute

/Second/A day of the week from 01 to 99.

Interrupt function with specifying date and time

(Year/Month/Day/Hour/Minute/Second/A day of the week.) is

available. This function is also available by specifying only

Year, Month, Day, Hour or Minute.

Timer interrupt function after set time or each set time.

Capable of rewriting the time with continuing the time count.

Leap year automatic count is available.
