SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER for INFRARED REMOTE CONTROL TRANSMITTERS
Fig. 24 Clock control circuit structure
Clock signal f(XIN) is obtained by externally connecting a ceramic
resonator. Connect this external circuit to pins XIN and XOUT at
the shortest distance as shown Figure 26.
A feedback resistor is built-in between XIN pin and XOUT pin.
ROM ORDERING METHOD
Please submit the information described below when ordering
Mask ROM.
(1) Mask ROM Order Confirmation Form................................. 1
(2) Data to be written into mask ROM .......................... EPROM
(three sets containing the identical data)
(3) Mark Specification Form .................................................... 1

Use the resonator
manufacturer’s
recommended value
because constants
such as capacitance
depend on the
resonator.
