Description
The μPD46364092B is a 4,194,304-word by 9-bit, the μPD46364182B is a 2,097,152-word by 18-bit and the μPD46364362B is a 1,048,576-word by 36-bit synchronous double data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.
The μPD46364092B, μPD46364182B and μPD46364362B 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
• 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. Normal operation is restored in 20 μs after clock is resumed.
• User programmable impedance output (35 to 70 Ω)
• Fast clock cycle time : 3.3 ns (300 MHz), 4.0 ns (250 MHz)
• Simple control logic for easy depth expansion
• JTAG 1149.1 compatible test access port
