PD44324082, 44324092, 44324182, 44324362
36M-BIT DDRII SRAM
2-WORD BURST OPERATION
Description
The
µ
PD44324082 is a 4,194,304-word by 8-bit, the
µ
PD44324092 is a 4,194,304-word by 9-bit, the
µ
PD44324182 is a
2,097,152-word by 18-bit and the
µ
PD44324362 is a 1,048,576-word by 36-bit synchronous double data rate static RAM
fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The
µ
PD44324082,
µ
PD44324092,
µ
PD44324182 and
µ
PD44324362 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 package (13 x 15)
•
HSTL Interface
•
DLL circuitry for wide output data valid window and future frequency scaling
•
Pipelined double data rate operation
•
Common data input/output bus
•
Two-tick burst for low DDR transaction size
•
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. Normal operation is restored in 1,024 cycles after clock is resumed.
•
User programmable impedance output
<R>
•
Fast clock cycle time : 3.7 ns (270 MHz), 4.0 ns (250 MHz), 5.0 ns (200 MHz)
•
Simple control logic for easy depth expansion
•
JTAG boundary scan
