00 Nov 09, 2012 Description The μPD46185092B is a 2,097,152-word by 9-bit, the μPD46185182B is a 1,048,576-word by 18-bit and the μPD46185362B 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 μPD46185092B, μPD46185182B and μPD46185362B 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 • 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.
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), 2.
0 ns (250 MHz) • Simple control logic for easy depth expansion • JTAG 1149.
1 compatible test access port R10DS0112EJ0200 Rev.
