• 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.
