DATA SHEET
MOS INTEGRATED CIRCUIT
µPD44324082, 44324092, 44324182, 44324362
36M-BIT DDRII SRAM
2-WORD BURST OPERATION
Description
The µPD44324082 is a 4,194,304-word by 8-bit, the µPD44324092 is a 4,194,304-word by 9-bit, the µPD44324182 is a
2,097,152-word by 18-bit and the µPD44324362 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 µPD44324082, µPD44324092, µPD44324182 and µPD44324362 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
