⢠Power Consumption Control
â Static HCMOS Technology Reduces Power in Normal Operation
â Low Voltage Operation at 3.3 V ±0.3 V (MC68340V only)
â Programmable Clock Generator Throttles Frequency
â Unused Peripherals Can Be Turned Off
â LPSTOP Provides an Idle State for Lowest Standby Current
⢠0â16.78 MHz or 0â25.16 MHz Operation
⢠144-Pin Ceramic Quad Flat Pack (CQFP) or 145-Pin Plastic Pin Grid Array (PGA)
As a low voltage part, the MC68340V can operate with a 3.3-V power supply. MC68340 is
used throughout this manual to refer to both the low voltage and standard 5-V parts since
both are functionally equivalent.
