Description
The
μ
PD44165084A is a 2,097,152-word by 8-bit, the
μ
PD44165094A is a 2,097,152-word by 9-bit, the
μ
PD44165184A
is a 1,048,576-word by 18-bit and the
μ
PD44165364A is a 524,288-word by 36-bit synchronous quad data rate static RAM
fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The
μ
PD44165084A,
μ
PD44165094A,
μ
PD44165184A and
μ
PD44165364A integrate unique synchronous
peripheral circuitry and a burst counter. All input registers controlled by an input clock pair (K and K#) are latched on
the positive edge of K and K#.
These products are suitable for application which require synchronous operation, high speed, low voltage, high density
and wide bit configuration.
These products are packaged in 165-pin PLASTIC BGA.
Features
•
1.8 ± 0.1 V power supply
•
165-pin PLASTIC BGA (13 x 15)
•
HSTL interface
•
PLL circuitry for wide output data valid window and future frequency scaling
•
Separate independent read and write data ports with concurrent transactions
•
100% bus utilization DDR READ and WRITE operation
•
Four-tick burst for reduced address frequency
•
Two input clocks (K and K#) for precise DDR timing at clock rising edges only
•
Two output clocks (C and C#) for precise flight time
