Devices that are lead-free are marked with a circled “e1” and have the product code: LUxxxxxx. a. This device is lead-free. That is, lead has not been intentionally added, but lead may still exist as an impurity at 1.8V > 1.2V. This is important to avoid stress in the ESD protection circuits. After 3.3V reaches 10% of its final value, all voltage rails (1.8V and 1.2V) have 150 ms to reach their final operating values. 3.3V Supply Voltage Ramp Parameter Rise Time Monotonicity Slope Operational Range Ripple Overshoot Description Time from 10% to 90% mark Voltage dip allowed in ramp Ramp rate at any time between 10% to 90% Voltage range for normal operating conditions Maximum voltage ripple at a bandwidth equal to 50 MHz Maximum voltage allowed 3 Min 0.1 Max 100 0 28800 3.6 70 4 Unit ms mV V/s V mV V Table 3.
