Appendix 9. M37906M4C-XXXFP electrical characteristics

Output-only pins are open,

and the other pins are con-

nected to Vss or Vcc. An

external square-waveform

clock is input. (Pin XOUT is

open.) The PLL frequency

multiplier is inactive.

Unit

µA

f(fsys) = 20 MHz.

CPU is active.

Ta = 25 °C when

clock is inactive.

Ta = 85 °C when

clock is inactive.

Test conditions

IOH = –10 mA

IOL = 10 mA

VI = 5.0 V

VI = 0 V

When clock is inactive.
