Description
The
μ
PD44164084A is a 2,097,152-word by 8-bit, the
μ
PD44164094A is a 2,097,152-word by 9-bit, the
μ
PD44164184A
is a 1,048,576-word by 18-bit and the
μ
PD44164364A 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
μ
PD44164084A,
μ
PD44164094A,
μ
PD44164184A and
μ
PD44164364A 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 BGA.
Features
•
1.8 ± 0.1 V power supply
•
165-pin PLASTIC BGA (13 x 15)
•
HSTL interface
•
PLL 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 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. Normal operation is restored in 1,024 cycles after clock is resumed.
•
User programmable impedance output
<R>
•
Fast clock cycle time : 3.3 ns (300 MHz), 3.7 ns (270 MHz), 4.0 ns (250 MHz), 5.0 ns (200 MHz)
