LPC2364/66/68

Fast communication chip

[1]

Typical ratings are not guaranteed. The values listed are at room temperature (25

°C), nominal supply voltages.

[2]

The RTC typically fails when Vi(VBAT) drops below 1.6 V.

[3]

Including voltage on outputs in 3-state mode.

[4]

VDD(3V3) supply voltages must be present.

[5]

3-state outputs go into 3-state mode when VDD(3V3) is grounded.

[6]

Accounts for 100 mV voltage drop in all supply lines.

[7]

Only allowed for a short time period.

[8]

Minimum condition for VI = 4.5 V, maximum condition for VI = 5.5 V.

[9]

On pin VBAT.
