DATA SHEET
MOS INTEGRATED CIRCUIT
µPD44164084, 44164184, 44164364
18M-BIT DDRII SRAM
4-WORD BURST OPERATION
Description
The µPD44164084 is a 2,097,152-word by 8-bit, the µPD44164184 is a 1,048,576-word by 18-bit and the
µPD44164364 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 µPD44164084, µPD44164184 and µPD44164364 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
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 : 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
