Holtek Semiconductor 

HT93LC46

Pin Description

Pin Name I/O

CS

I Chip select input

Description

SK

I Serial clock input

DI

I Serial data input

DO

O Serial data output

VSS

— Negative power supply, ground

ORG

Internal Organization

I

When ORG is connected to VDD or ORG is floated, the (×16) memory organization is selected.

When ORG is tied to VSS, the (×8) memory organization is selected. There is an internal pull-up

resistor on the ORG pin.

NC

— No connection

VCC

— Positive power supply

Absolute Maximum Ratings

Supply Voltage .......................... VSS−0.3V to VSS+6.0V

Input Voltage............................. VSS−0.3V to VCC+0.3V

Storage Temperature............................−50°C to 125°C

Operating Temperature..........................−40°C to 85°C

Note: These are stress ratings only. Stresses exceeding the range specified under ″Absolute Maximum Ratings″

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.
