WP Pin Timing
NOTES:
1. Typical values are for TA = +25°C and 3.3V supply voltage.
2. LSB: [V(RW)255 – V(RW)0]/255. V(RW)255 and V(RW)0 are V(RW) for the DCP register set to FF hex and 00 hex respectively. LSB is the
incremental voltage when changing from one tap to an adjacent tap.
3. ZS error = V(RW)0/LSB.
4. FS error = [V(RW)255 – VCC]/LSB.
5. DNL = [V(RW)i – V(RW)i-1]/LSB-1, for i = 1 to 255. i is the DCP register setting.
6. INL = [V(RW)i – (i LSB – V(RW)0)]/LSB for i = 1 to 255.
7.
for i = 16 to 240 decimal, T = -40°C to +85°C. Max( ) is the maximum value of the wiper
voltage and Min ( ) is the minimum value of the wiper voltage over the temperature range.
8. MI =
|R255 – R0|/255. R255 and R0 are the measured resistances for the DCP register set to FF hex and 00 hex respectively.
Roffset = R0/MI, when measuring between RW and RL.
9. Roffset = R255/MI, when measuring between RW and RH.
10. RDNL = (Ri – Ri-1)/MI, for i = 32 to 255.
11. RINL = [Ri – (MI i) – R0]/MI, for i = 32 to 255.
12.
for i = 32 to 255, T = -40°C to +85°C. Max( ) is the maximum value of the resistance and Min ( ) is the
minimum value of the resistance over the temperature range.
13. This parameter is not 100% tested.
14. tWC is the minimum cycle time to be allowed for any non-volatile Write by the user, unless Acknowledge Polling is used. It is the time from a
valid STOP condition at the end of a Write sequence of a I2C serial interface Write operation, to the end of the self-timed internal non-volatile
write cycle.
15. VIL = 0V, VIH = VCC

Maximum is determined by tR and tF.
For Cb = 400pF, max is about 2~2.5k
.
For Cb = 40pF, max is about 15~20k
