NOTE FOR SUPPLYING POWER
(1)
__
Timing of power supplying to AC pin
The internal circuit of M35080FP is reset when the level of the
__
auto clear input pin AC is “L”. This pin in hysteresis input with the
pull-up resistor.
__
The timing about power supplying of AC pin is shown in Figure be-
low.
After supplying the power (VDD and VSS) to M35080FP and the
supply voltage becomes more than 0.8 VDD, it needs to keep
__
VIL time; tw of the AC pin for more than 1ms.
__
Start inputting from microcomputer after AC pin supply voltage
becomes more than 0.8 VDD and keeping 200ms wait time.
PRECAUTION FOR USE
Notes on noise and latch-up
In order to avoid noise and latch-up, connect a bypass capacitor
(
≈0.1F) directly between the VDD1 pin and VSS1 pin, and the
VDD2 pin and VSS2 pin using a heavy wire.
Notes on the time of external clock input to TCK pin
Input the continuous external clock which cycle is fixed and syn-
chronized with horizontal synchronized signal from TCK pin. And,
input continuous horizontal synchronized signal which cycle is
fixed from HOR pin. Do not stop clock input absolutely during dis-
play.
(2) Timing of power supplying to VDD1 and VDD2.
Supply power to VDD1 and VDD2 at the same time.
