MC68LC302 Datasheet, PDF (97/169 Pages) Motorola, Inc – Low Power Integrated Multiprotocol Processor Reference Manual

Signal Description
All pins except EXTAL, CLKO, and the layer 1 interface pins in IDL mode support TTL levels.
EXTAL, when used as an input clock, needs a CMOS level. CLKO supplies a CMOS level
output. The IDL interface is specified as a CMOS electrical interface.
All outputs (except CLKO and the GCI pins) drive 100 pF. CLKO is designed to drive 50 pF.
The GCI output pins drive 100 pF.
5.2 POWER PINS
The LC302 (TQFP) has 17 power supply pins. Careful attention has been paid to reducing
LC302 noise, potential crosstalk, and RF radiation from the output drivers. Inputs may be +5
V when V_DD is 0 V without damaging the device.
• V_DD (6)—There are 6 power pins.
• GND (11)—There are 11 ground pins.
