Description

Power supply

VCC

Input

Digital voltage supply pin. This is used as the digital power supply for the

respective modules and internal voltage regulator, and used to monitor the

voltage of the POR/LVD. Connect to the system power supply. Connect to

VSS through a 0.1-μF smoothing capacitor close to each VCC pin.

VCL0

Connect to VSS through a 0.1-μF smoothing capacitor close to each VCL

pin. Stabilize the internal power supply.

VCL

VSS

Input

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

VBATT

Input

Backup power pin

Clock

XTAL

Output

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

EXTAL pin.

EXTAL

Input

XCIN

Input

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

between XCOUT and XCIN.

XCOUT

Output

EBCLK

Output

Outputs the external bus clock for external devices

SDCLK

Output

Outputs the SDRAM-dedicated clock

CLKOUT

Output

Clock output pin

Operating mode

control

Input

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

changed during operation mode transition on release from the reset state.

System control

RES

Input

Reset signal input pin. The MCU enters the reset state when this signal goes

low.

CAC

CACREF

Input

Measurement reference clock input pin

Interrupt

NMI

Input

Non-maskable interrupt request pin

IRQ0 to IRQ15

Input

Maskable interrupt request pins

KINT

KR00 to KR07

Input

A key interrupt can be generated by inputting a falling edge to the key

interrupt input pins

On-chip emulator

TMS

I/O

SWDIO

I/O

Serial wire debug data input/output pin

SWCLK

Input

Serial wire clock pin

SWO

Output

Serial wire trace output pin
