Description
The µPD48288118AF1 is a 16,777,216-word by 18 bit synchronous double data rate Low Latency RAM fabricated with
advanced CMOS technology using one-transistor memory cell.
The µPD48288118AF1 integrate unique synchronous peripheral circuitry and a burst counter. All input registers controlled
by an input clock pair (CK and CK#) are latched on the positive edge of CK and CK#. These products are suitable for
application which require synchronous operation, high speed, low voltage, high density and wide bit configuration.
