DATA SHEET
MOS INTEGRATED CIRCUIT
µPD44165082, 44165182, 44165362
18M-BIT QDRTMII SRAM
2-WORD BURST OPERATION
Description
The µPD44165082 is a 2,097,152-word by 8-bit, the µPD44165182 is a 1,048,576-word by 18-bit and the
µPD44165362 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 µPD44165082, µPD44165182 and µPD44165362 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
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 : 5.0 ns (200 MHz), 6.0 ns (167 MHz), 7.5 ns (133 MHz)
Simple control logic for easy depth expansion
JTAG boundary scan
