NOTE FOR SUPPLYING POWER
(1) Timing of power supplying to AC pin
The internal circuit of M35060-XXXSP is reset when the level of
the auto clear input pin AC is “L”.
This pin is hysteresis input with the pull-up resistor. The timing
about power supplying of AC pin is shown in Figure 15.
tw is the interval after the supply voltage becomes 0.8 VDD or
more and before the supply voltage to the AC pin (VAC) becomes
0.2 VDD or more.
After supplying the power (VDD and VSS) to M35060-XXXSP, the
tW time must be reserved for 1 ms or more.
Before starting input from the microcomputer, the waiting time
(ts) must be reserved for 200 ms after the supply voltage to the
AC pin becomes 0.8 VDD or more.
(2) Timing of power supplying to VDD1 pin and VDD2 pin
The power need to supply to VDD1 and VDD2 at a time, though it
is separated perfectly between the VDD1 as the digital line and
the VDD2 as the analog line.

PRECAUTION FOR USE
Notes on noise and latch-up
Connect a capacitor (approx. 0.1F) between pins VDD and VSS at
the shortest distance using relatively thick wire to prevent noise and
latcj up.
ROM ORDERING METHOD
Please submit the information described below when ordering Mask
ROM.
(1) 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
(4) Program for character font generating + froppy disk in which
character data is input.
