5 / 10 page 5 FN8096.1 January 16, 2006 SDA vs SCL Timing A0 and A1 Pin Timing NOTES: 1. Typical values are for TA = 25°C and 3.3V supply voltage. 2. MI = |R255 – R0| / 255. R255 and R0 are the measured resistances for the DCP register set to FF hex and 00 hex, respectively. 3. Roffset = R255 / MI, when measuring between RW and RH. 4. RDNL = (Ri – Ri-1) / MI, for i = 32 to 255. 5. RINL = [Ri – (MI • i) – R0] / MI, for i = 32 to 255. 6. RMATCH = (Ri,x – Ri,y) / MI, for i = 0 to 255, x = 0 to 3 and y = 0 to 3. 7. 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. 8. This parameter is not 100% tested. tSU:A A1 and A0 setup time Before START condition 600 ns tHD:A A1 and A0 hold time After STOP condition 600 ns Operating Specifications Over the recommended operating conditions unless otherwise specified.
