ADVANCE INFORMATION

83C196LC, 83C196LD — AUTOMOTIVE

XTAL1

I

Input Crystal/Resonator or External Clock Input

Input to the on-chip oscillator and the internal clock generators. The internal

clock generators provide the peripheral clocks, CPU clock, and CLKOUT

signal. When using an external clock source instead of the on-chip oscillator,

connect the clock input to XTAL1. The external clock signal must meet the V

IH

specification for XTAL1.

XTAL2

O

Inverted Output for the Crystal/Resonator

Output of the on-chip oscillator inverter. Leave XTAL2 floating when the design

uses an external clock source instead of the on-chip oscillator.
