Description

Power supply

VCC

Input

Power supply pin. Connect it to the system power supply.

VCL

—

Connect this pin to the VSS pin via the 4.7

μF smoothing capacitor used to

stabilize the internal power supply. Place the capacitor close to the pin.

VSS

Input

Ground pin. Connect it to the system power supply (0 V).

VBATT

Input

Backup power pin

Clock

XTAL

Output

Pins for connecting a crystal. An external clock can be input through the

EXTAL pin.

EXTAL

Input

BCLK

Output

Outputs the external bus clock for external devices.

XCIN

Input

Input/output pins for the sub-clock oscillator. Connect a crystal between

XCIN and XCOUT.

XCOUT

Output

CLKOUT

Output

Clock output pin.

Operating mode

control

MD

Input

Pin for setting the operating mode. The signal levels on this pin must not

be changed during operation.

UB

Input

Pin used for boot mode (USB interface).

UPSEL

Input

Pin used for boot mode (USB interface).

System control

RES#

Input

Reset pin. This MCU enters the reset state when this signal goes low.

CAC

CACREF

Input

Input pin for the clock frequency accuracy measurement circuit.

On-chip

emulator

FINED

I/O

FINE interface pin.

Address bus

A0 to A23

Output

Output pins for the address.

Data bus

D0 to D15

I/O

Input and output pins for the bidirectional data bus.

Multiplexed bus

A0/D0 to A15/D15

I/O

Address/data multiplexed bus

Bus control

RD#

Output

Strobe signal which indicates that reading from the external bus interface

space is in progress.

WR#

Output

Strobe signal which indicates that writing to the external bus interface

space is in progress, in single-write strobe mode.

WR0#, WR1#

Output

Strobe signals which indicate that either group of data bus pins (D7 to D0,

and D15 to D8) is valid in writing to the external bus interface space, in

byte strobe mode.

BC0#, BC1#

Output

Strobe signals which indicate that either group of data bus pins (D7 to D0

and D15 to D8) is valid in access to the external bus interface space, in

single-write strobe mode.

CS0# to CS3#

Output

Select signals for areas 0 to 3.

WAIT#

Input

Input pin for wait request signals in access to the external space.

ALE

Output

Address latch signal when address/data multiplexed bus is selected.

LVD

CMPA2

Input

Detection target voltage pin for voltage detection 2.

Interrupts

NMI

Input

Non-maskable interrupt request pin.

IRQ0 to IRQ7

Input

Interrupt request pins.
