Negative power supply, ground
Internal Organization
When ORG is connected to VDD or ORG is floated, the (´16) memory organization is se-
lected. When ORG is tied to VSS, the (´8) memory organization is selected. There is an in-
ternal pull-up resistor on the ORG pin.
No connection
Positive power supply
Absolute Maximum Ratings
Operation Temperature (Industrial) ..........................................................................................................-40°C to 85°C
Applied VCC Voltage with Respect to VSS..................................................................................................-0.3V to 6.0V
Applied Voltage on any Pin with Respect to VSS..................................................................................................VSS-0.3V to VCC+0.3V
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reli-
ability.
