MB9B100A Series

[I2C]

Standard-mode (Max.100 kbps) / Fast-mode (Max.400 kbps)

supported

External Bus Interface

Supports SRAM, NOR& NAND Flash device

Up to 8 chip selects

8-/16-bit Data width

Up to 25-bit Address bit

Maximum area size : Up to 256 Mbytes

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: 32bit(4Gbyte)

Transfer mode: Block transfer/Burst transfer/Demand

transfer

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

Transfer block count: 1 to 16

Number of transfers: 1 to 65536

A/D Converter (Max. 16 channels)

[12-bit A/D Converter]

Successive Approximation Register type

Built-in 3unit

Conversion time: 1.0 μs@5 V

Priority conversion available (priority at 2 levels)

Scanning conversion mode

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

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

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

Multi-function Timer (Max. 2 units)

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

16-bit free-run timer × 3 ch/unit

Input capture × 4 ch/unit

Output compare × 6 ch/unit

A/D activation compare × 3 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

Quadrature Position/Revolution Counter (QPRC)

(Max. 2 units)

The Quadrature Position/Revolution Counter (QPRC) is used

to measure the position of the position encoder. Moreover, it is

possible to use up/down counter.

The detection edge of the three external event input pins

AIN, BIN and ZIN is configurable.

16-bit position counter

16-bit revolution counter

Two 16-bit compare registers

Dual Timer (Two 32-/16bit Down Counter)

The Dual Timer consists of two programmable 32-/16-bit down

counters.

Operation mode is selectable from the followings for each

channel.

Free-running

Periodic (=Reload)

One-shot

Watch Counter

The Watch counter is used for wake up from sleep mode.

Interval timer: up to 64 s (Max.)@ Sub Clock: 32.768 kHz
