LPC2927/2929
ARM9 microcontroller with CAN, LIN, and USB
9.3 Dynamic characteristics: I2C-bus interface
Table 38. Dynamic characteristic: I2C-bus pins
VDD(CORE) = VDD(OSC_PLL); VDD(IO) = 2.7 V to 3.6 V; VDDA(ADC3V3) = 3.0 V to 3.6 V; all voltages are measured with respect to
ground; positive currents ï¬ow into the IC; unless otherwise speciï¬ed[1]

[1] All parameters are guaranteed over the virtual junction temperature range by design. Pre-testing is performed at Tamb = 85 °C ambient
temperature on wafer level. Cased products are tested at Tamb = 25 °C (ï¬nal testing). Both pre-testing and ï¬nal testing use correlated
test conditions to cover the speciï¬ed temperature and power supply voltage range.
[2] Typical ratings are not guaranteed. The values listed are at room temperature (25 °C), nominal supply voltages.
[3] Bus capacitance Cb in pF, from 10 pF to 400 pF.
