Clock timer

15-bit timer

Interrupt interval : 0.438, 0.5, or 2.0 µs for sub-clock frequency = 32.768 kHz

8/16-bit PPG timer

Number of channels : 1 (Can be used in 2 × 8-bit channel mode)

Can generate a pulse waveform output with specified period and 0 to 100% duty ratio.

8/16 -bit up/down

counter/timers

Number of channels : 1 (Can be used in 2 × 8-bit channel mode)

External event inputs : 6 channels

Reload/compare function : 8-bit × 2 channels

Clock monitor

Clock output frequency : Machine clock/21 to machine clock/28

Delayed interrupt

generation module

Interrupt generation module for task switching. (Used by REALOS.)

DTP/External

interrupts

Input channels : 8

Generates interrupts to the CPU on rising edges, falling edges with input “H” level, or “L”

level.

Can be used for external event interrupts and to activate EI2OS.

Wakeup interrupts

Input channels : 8

Triggered by “L” level.

8/10-bit A/D converter

(successive

approximation type)

Number of channels : 8

Resolution : 8-bit or 10-bit selectable

Conversion can be performed sequentially for multiple consecutive channels.

• Single-shot conversion mode : Converts specified channel once only.

• Continuous conversion mode : Repeatedly converts specified channel.

• Intermittent conversion mode : Converts specified channel then halts temporarily.

8-bit D/A converter

(R-2R type)

Number of channels : 2

Resolution : 8-bit

UART (SCI)

Number of channels : 1

Clock synchronous transfer : 62.5 Kbps to 1 Mbps

Clock asynchronous transfer : 1202 bps to 31250 bps

Supports bi-directional and master-slave communications.

Extended I/O serial

interface

Number of channels : 2

Clock synchronous transfer : 31.25 Kbps to 1 Mbps (Using internal shift clock)

Transmission format : Selectable LSB-first or MSB-first

LCD controller/driver

Number of common outputs : 4

Number of segment outputs : 32

Number of power supply pins for LCD ttdrive : 4

LCD display memory : 16 bytes

Divider resistor for LCD drive : Internal

*1 : As for the necessity of a DIP switch setting (S2) when using the emulation pod (MB2145-507) .

Refer to the hardware manual for the emulation pod (MB2145-507) fomr details.

*2 : Take note of the maximum operating frequency and A/D converter precision restrictions when operating at 3.0 V

to 3.6 V. See the “Electrical Characteristics” section for details.
