DS1321
11 of 13
NOTES:
2. All voltages referenced to ground.
3. Measured with outputs open circuited.
4. ICCO1 is the maximum average load which the DS1321 can supply to attached memories at VCCO ≥ VCCI
-0.2V.
5. ICCO2 is the maximum average load which the DS1321 can supply to attached memories at VCCO ≥ VCCI
-0.3V.
6. All inputs within 0.3V of ground or VCCI.
7. ICCO3 is the maximum average load current which the DS1321 can supply to the memories in the
battery backup mode at VCCO ≥ VBAT -0.2V.
8. Measured with a load as shown in Figure 1.
9. Chip Enable Outputs CEO1 - CEO4 can only sustain leakage current in the battery backup mode.
10. CEO1 through CEO4 will be held high for a time equal to tREC after VCCI crosses VCCTP on power-up.
11. BW and RST are open drain outputs and, as such, cannot source current. External pullup resistors
should be connected to these pins for proper operation. Both BW and RST can sink 10 mA.
12. tCE maximum must be met to ensure data integrity on power down.
13. In battery backup mode, inputs must never be below ground or above VCCO.
14. The DS1321 is recognized by Underwriters Laboratories (UL) under file E99151.
