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
