P89LPC980/982/983/985

8-bit microcontroller with accelerated two-clock 80C51 core

Limiting values

[1]

The following applies to Table 12:

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 ambient temperature range unless otherwise specified. All voltages are with respect to VSS unless

otherwise noted.

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

Ω series resistor.
