AC Characteristics
(1) Reset, Hardware Standby Input Timing
(AVCC = VCC = 5.0 V
±10%, AVSS = VSS = 0.0 V, TA = –40°C to +85°C)
* : Oscillation time of oscillator is time that the amplitude reached the 90 %.
In the crystal oscillator, the oscillation time is between several ms to tens ms. In FAR/ceramic oscillator, the
oscillation time is between hundreds of
s to several ms. In the external clock, the oscillation time is 0 ms.
Note : For tCP (internal operating clock cycle time), refer to “(3) Clock Timings.”

Pin
CL
CL is a load capacitance connected to a pin under test.
Capacitors of CL = 30 pF must be connected to CLK and ALE pins, while CL of 80 pF must
be connected to address data bus (AD15 to AD00), RD, WRL, and WRH pins.
