Description
Chip select input
Serial clock input
Serial data input
Serial data output
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
Supply Voltage ...........................VSS-0.3V to VSS+6.0V
Input Voltage.............................VSS-0.3V to VDD+0.3V
Storage Temperature ............................-50°C to 125°C
Operating Temperature...............................0°C to 70°C
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 reliability.
