Note:

AC measurement conditions:

–

CL: 100 pF

–

RPUP (SDA bus line pull-up resistor to VCC): 1.3 kΩ (1000 kHz), 4 kΩ (400 kHz),

10 kΩ (100 kHz)

–

Input pulse voltages: 0.3 x VCC to 0.7 x VCC

–

Input rise and fall times: ≤50 ns

–

Input and output timing reference voltages: 0.5 x VCC

These parameters are determined through product characterization and are not 100% tested in

production.

Power-Up Requirements and Reset Behavior

During a power-up sequence, the VCC supplied to the AT24C01C/AT24C02C should monotonically rise

from GND to the minimum VCC level, as specified in Table 4-1, with a slew rate no faster than 0.1 V/µs.
