LPC2470

Flashless 16-bit/32-bit microcontroller

Limiting values

[1]

The following applies to the limiting values:

a) This product includes circuitry speciﬁcally designed for the protection of its internal devices from the damaging effects of excessive

static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.

b) Parameters are valid over operating temperature range unless otherwise speciﬁed. All voltages are with respect to VSSIO/VSSCORE

unless otherwise noted.

[2]

Including voltage on outputs in 3-state mode.

[3]

Not to exceed 4.6 V.

[4]

The peak current is limited to 25 times the corresponding maximum current.

[5]

Dependent on package type.

[6]

Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k

Ω series resistor.
