(8) Hold Timing
(MB90F543/F549 : VCC
= 4.5 V to 5.5 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
(MB90543G(S)/547G(S)/548G(S)/F548GL(S): VCC
= 3.5 V to 5.5 V, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
(Other than MB90F543/F549/543G(S)/547G(S)/548G(S)/F548GL(S):
VCC
= 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
Note : There is more than 1 cycle from the time HRQ is read to the time the HAK is changed.
(9) UART0/1, Serial I/O Timing
(MB90F543/F549 : VCC
= 4.5 V to 5.5 V, VSS = 0.0 V, TA = 40 °C to +85 °C)
(MB90543G(S)/547G(S)/548G(S)/F548GL(S): VCC
= 3.5 V to 5.5 V, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
(Other than MB90F543/F549/543G(S)/547G(S)/548G(S)/F548GL(S):
VCC
= 5.0 V ± 10%, VSS = AVSS = 0.0 V, TA = 40 °C to +105 °C)
Note :
AC characteristic in CLK synchronized mode.
CL is load capacity value of pins when testing.
For tCP (Machine clock cycle time) , refer to “ (1) Clock Timing”.
