SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
TIMING REQUIREMENTS (VCC = 5 V ± 10%, VSS = 0 V, Ta = –20 to 85 °C, f(XIN) = 25 MHz, unless otherwise noted (Note))
Notes 1. This applies when the main clock division selection bit = “0” and f(f2) = 12.5 MHz.
2. Input signal’s rise/fall time must be 100 ns or less, unless otherwise noted.

Notes 3. When the main clock division selection bit = “1”, the minimum value of tc = 80 ns.
4. When the main clock division selection bit = “1”, values of tw(H) / tc and tw(L) / tc must be set to values from 0.45 through 0.55.
