TIMING REQUIREMENTS
Table 12 Timing requirements (1)
(VCC = 4.0 to 5.5 V, VSS = 0 V, Ta = –20 to 85 °C, unless otherwise noted)
Symbol
Parameter
tW(RESET)
Reset input “L” pulse width
tC(XIN)
External clock input cycle time
tWH(XIN)
External clock input “H” pulse width
tWL(XIN)
External clock input “L” pulse width
tC(CNTR)
CNTR0, CNTR1 input cycle time
tWH(CNTR)
CNTR0, CNTR1, INT0–INT3 input “H” pulse width
tWL(CNTR)
CNTR0, CNTR1, INT0–INT3 input “L” pulse width
tC(SCLK)
Serial I/O clock input cycle time (Note)
tWH(SCLK)
Serial I/O clock input “H” pulse width (Note)
tWL(SCLK)
Serial I/O clock input “L” pulse width (Note)
tsu(RxD-SCLK)
Serial I/O input setup time
th(SCLK-RxD)
Serial I/O input hold time
Note : When f(XIN) = 8 MHz and bit 6 of address 001A16 is “1” (clock synchronous).
Divide this value by four when f(XIN) = 8 MHz and bit 6 of address 001A16 is “0” (UART).
