• File name of object code
• Date
• Name of operating system that formatted diskette
• Formatted capacity of diskette
Pinout
SpecificationsMaximum ratings are the extreme limits to which the MCU can be exposed without permanently damaging it.
The MCU contains circuitry to protect the inputs against damage from high static voltages; however, do not apply voltages higher than those shown in the table below. Keep VIN and VOUT within the range VSS (VIN or VOUT) VDD. Connect unused inputs to the appropriate voltage level, either VSS or VDD

1. Power dissipation is a function of temperature.
2. K is a constant unique to the device. K can be determined from a known TA and measured PD. With this value of K, PD and TJ can be determined for any value of TA.DescriptionMotorola reserves the right to make changes without further notice to any products herein to improve reliability, function or design.
