µ
PD44165084, 44165184, 44165364
18M-BIT QDR
TM
II SRAM
4-WORD BURST OPERATION
Description
The
µ
PD44165084 is a 2,097,152-word by 8-bit, the
µ
PD44165184 is a 1,048,576-word by 18-bit and the
µ
PD44165364 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
PD44165084,
µ
PD44165184 and
µ
PD44165364 integrates 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 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 : 4.0 ns (250 MHz) , 5.0 ns (200 MHz) , 6.0 ns (167 MHz)
•
Simple control logic for easy depth expansion
•
JTAG boundary scan
