Description
RD3ST24 is including the standby control circuit for a microcomputer in 8 pin packages.
When MSTB input "Low", SWOUT output "Low", STBYOUT output become “High” and cancels standby condition.
And RESOUT output becomes High after it passed period (t1*) when it is stable the oscillation that was set up with RC bill outside and cancel the reset condition of a microcomputer.
Also when MSTB input "Low", RESOUT output becomes "Low" and makes reset condition.
After the delay time (t2) of prescription passed subsequently, SWOUT output "High" STBYOUT output becomes "Low" and makes a microcomputer standby condition.
*: t1 = K•RC (K is coefficient: Reference of application data)
