IDT70824S/L
High-Speed 4K x 16 Sequential Access Random Access Memory
Military and Commercial Temperature Ranges
15
Sequential Port: Write, Pointer Load Non-Incrementing Read
NOTES:
1. If
SLD = VIL, then address will be clocked in on the SCLK's rising edge.
2. If
CNTEN = VIH for the SCLK's rising edge, the internal address counter will not advance.
3. Pointer is not incremented on cycle immediately following
SLD even if CNTEN is LOW.
Sequential Port: AC Electrical Characteristics
Over the Operating Temperature and Supply Voltage(1,2)
NOTES:
1. 'X' in part numbers indicates power rating (S or L).
2. Industrial temperature: for specific speeds, packages and powers contact your sales office.
