8 / 20 page ISL97649A 8 FN7928.0 December 5, 2011 tSU:DAT Input Data Set-up Time From SDA exiting the 30% to 70% of VIN window, to SCL rising edge crossing 30% of VIN 40 ns tHD:DAT Input Data Hold Time From SCL rising edge crossing 70% of VIN to SDA entering the 30% to 70% of VIN window 0ns tSU:STO STOP Condition Set-up Time From SCL rising edge crossing 70% of VIN, to SDA rising edge crossing 30% of VIN 400 ns tHD:STO STOP Condition Hold Time for Read, or Volatile Only Write From SDA rising edge to SCL falling edge; both crossing 70% of VIN 400 ns CSCL Capacitive on SCL 5pF CSDA Capacitive on SDA 5pF tWp Non-Volatile Write Cycle Time 25 ms EEPROM Endurance TA= +25°C 1 kCyc EEPROM Retention TA = +25°C 88 kHrs NOTES: 6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. 7. Typical values are for TA = +25°C and VIN = 3.3V. 8. LSB = I V255 - V1I / 254. V255 and V1 are the measured voltages for the DCP register set to FF hex and 01 hex respectively. 9. DNL = I Vi+1 - Vi I / LSB-1, 10. ZS error = (V1 -VMIN) / LSB. VMIN = (VAVDD*R2) * [1-254*R1/(255*20*RSET)]/ (R1+R2). 11. FS error = (V255 - VMAX) / LSB. VMAX= (VAVDD*R2) * [1-0*R1/(255*20*RSET)]/ (R1+R2). 12. Established by design. Not a parametric spec. 13. Boost will stop switching as soon as boost output reaches OVP threshold. 14. Compliance to limits is assured by characterization and design. Serial Interface Specifications For SCL and SDA Unless Otherwise Noted.
