Description
The µPD44164085 is a 2,097,152-word by 8-bit, the µPD44164185 is a 1,048,576-word by 18-bit and the
µPD44164365 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 µPD44164085, µPD44164185 and µPD44164365 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
Features
- 1.8 ± 0.1 V power supply and HSTL I/O.
- DLL circuitry for wide output data valid window and future frequency scaling.
- Separate independent read and write data ports.
- DDR read or write operation initiated each cycle.
- Pipelined double data rate operation.
- Separate 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 outpu.
