uPD44325362B
Overview
The μPD44325092B is a 4,194,304-word by 9-bit, the μPD44325182B is a 2,097,152-word by 18-bit and the μPD44325362B is a 1,048,576-word by 36-bit synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell. The μPD44325092B, μPD44325182B and μPD44325362B integrate unique synchronous peripheral circuitry and a burst counter.
- 1.8 ± 0.1 V power supply
- 165-pin PLASTIC BGA (15 x 17)
- 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
