Description
The
μ
PD44325084 is a 4,194,304-word by 8-bit, the
μ
PD44325094 is a 4,194,304-word by 9-bit, the
μ
PD44325184 is a
2,097,152-word by 18-bit and the
μ
PD44325364 is a 1,048,576-word by 36-bit synchronous quad data rate static RAM
fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The
μ
PD44325084,
μ
PD44325094,
μ
PD44325184 and
μ
PD44325364 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 FBGA.
Features
1.8 ± 0.1 V power supply and HSTL I/O
DLL 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
and clock skew matching-clock and data delivered together to receiving device
Internally self-timed write control
Clock-stop capability with
μ
s restart
User programmable impedance output
Fast clock cycle time : 3.3 ns (300 MHz) , 4.0 ns (250 MHz) , 5.0 ns (200 MHz)
Simple control logic for easy depth expansion
JTAG boundary scan
