LPC2387

Single-chip 16-bit/32-bit MCU

[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]

VDD(DCDC)(3V3) = 3.3 V; VDD(3V3) = 3.3 V; Vi(VBAT) = 3.3 V; Tamb =25 C.

[4]

On pin VBAT.

[5]

Including voltage on outputs in 3-state mode.

[6]

VDD(3V3) supply voltages must be present.

[7]

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

[8]

Please also see the errata note in errata sheet.

[9]

Accounts for 100 mV voltage drop in all supply lines.

[10] Allowed as long as the current limit does not exceed the maximum current allowed by the device.

[11] Minimum condition for VI = 4.5 V, maximum condition for VI =5.5 V.

[12] To VSS.
