MB90640A Series
(10) I/O Extended Serial Timing
(VCC = 4.5 V to 5.5 V, VSS = 0.0 V, TA = –40°C to +85°C)
Notes: These are the AC characteristics for CLK synchronous mode.
CL is the load capacitance connected to the pin at testing.
tCP is the machine cycle period (unit: ns).
The values in the upper table are targets.
