DS12887A Datasheet, PDF (18/19 Pages) Maxim Integrated Products – Real-Time Clock

DS5000(T)
NOTES:
1. All voltages are referenced to ground.
2. Maximum operating I_CC is measured with all output pins disconnected; XTAL1 driven with t_CLKR, t_CLKF=10 ns,
V_IL = 0.5V; XTAL2 disconnected; EA = RST = PORT0 = V_CC.
3. Idle mode I_CC is measured with all output pins disconnected; XTAL1 driven with t_CLKR, t_CLKF = 10 ns, V_IL = 0.5V;
XTAL2 disconnected; EA = PORT0 = V_CC, RST = V_SS.
4. Stop mode I_CC is measured with all output pins disconnected; EA = PORT0 = V_CC; XTAL2 not connected;
RST = V_SS.
5. Crystal start–up time is the time required to get the mass of the crystal into vibrational motion from the time that
power is first applied to the circuit until the first clock pulse is produced by the on–chip oscillator. The user should
check with the crystal vendor for the worst case spec on this time.
