DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD44164085, 44164185, 44164365  
18M-BIT DDRII SRAM SEPARATE I/O  
2-WORD BURST OPERATION  
Description  
The µPD44164085 is a 2,097,152-word by 8-bit, the µPD44164185 is a 1,048,576-word by 18-bit and the  
µPD44164365 is a 524,288-word by 36-bit synchronous double data rate static RAM fabricated with advanced CMOS  
technology using full CMOS six-transistor memory cell.  
The µPD44164085, µPD44164185 and µPD44164365 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  
DDR read or write operation initiated each cycle  
Pipelined double data rate operation  
Separate 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 with µs 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
