• PRECAUTION TO
USE
THE
EPROM
ON-PACKAGE
4 BIT SINGLE CHIP MICROCOMPUTER
Please pay attention
to
the followings, since this
MCU
has
special structure with pin socket on the package.
(1)
Don't apply high static voltage or surge voltage over
MAX-
IMUM
RATINGS
to
the socket pins
as
well
as
the LSI
pins.
If
not,
that
may cause permanent damage
to
the device.
(2)
When
using this in production like mask
ROM
type single
chip microcomputer, pay attention
to
the followings
to
keep the good contact between the EPROM pins and socket
pins.
(a) When soldering the LSI on a print circuit board, the
recommended condition
is
Temperature: lower than 250°C
Time : within 10 sec.
Over time/temperature may cause the bonding solder
of
socket pin
to
melt and the socket pin may drop.
(b) Note that the detergent or coating will not get in
the socket during flux washing or board coating
after soldering, because that may cause bad effect on
socket contact.
(c) Avoid permanent application
of
this under the con-
dition
of
Vibratory place and system.
(d) The socket, inserted and pulled repeatedly loses its
contactability.
It
is
recommended
to
use
new one when
applied
in
production.
