Function

Power

supply

VCC

F9, G10

Input

For connection to the power supply.

Connect all VCC pins to the system power

supply.

CVCC

E2, F3

Input

With a 5-V external power supply

(H8S/2238B used), connect a 0.1-µF

stabilization capacitance between this pin

and ground. Permanent damage on the

chip may result if the absolute maximum

rating of CVCC 4.3 V is exceeded. Must not

connect the 5 V external power supply to

this pin.

With a 3-V external power supply

(H8S/2239, H8S/2238R, and H8S/2236R

used), connect this pin to the system

power supply. See section 25, Power

Supply Circuit, for connection examples.

VSS

F3, F2

F10, F8

Input

For connection to the power supply (0 V).

Connect all VSS pins to the system power

supply (0 V).

Clock

XTAL

F11

Input

For connection to a crystal resonator. For

examples of crystal resonator connection

and external clock input, see section 23,

Clock Pulse Generator.

EXTAL

E11

Input

For connection to a crystal resonator. This

pin can be also used for external clock

input. For examples of crystal resonator

connection and external clock input, see

section 23, Clock Pulse Generator.

OSC1

H11

Input

Connects to a 32.768 kHz crystal

resonator. See section 23, Clock Pulse

Generator, for typical connection diagrams

for a crystal resonator.
