PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD44324084, 44324094, 44324184, 44324364
36M-BIT DDRII SRAM
4-WORD BURST OPERATION
Description
The µPD44324084 is a 4,194,304-word by 8-bit, the µPD44324094 is a 4,194,304-word by 9-bit, the µPD44324184 is a
2,097,152-word by 18-bit and the µPD44324364 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 µPD44324084, µPD44324094, µPD44324184 and µPD44324364 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
Pipelined double data rate operation
Common data input/output bus
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 µs 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
