NETSOL S7R323684M
The S7R323684M, S7R321884M and S7R320984M are 37,748,736-bits Quadruple Synchronous Pipelined Burst SRAMs. They are organized as 1,048,576 words by 36bits for S7R323684M, 2,097,152 words by 18bits for S7R321884M and 4,194,304 words by 9bits for S7R320984M. The Quadruple operation is possible by supporting DDR read and write operations through separate data output and input ports with the same cycle.FEATURES
●1.8V+0.1V/-0.1V Power Supply.●DLL circuitry for wide output data valid window and future fre- quency scaling.
● I/O Supply Voltage 1.5V+0.1V/-0.1V for 1.5V I/O, 1.8V+0.1V/ -0.1V for 1.8V I/O
●Separate independent read and write data ports with concurrent read and write operation
● HSTL I/O
● Full data coherency, providing most current data.
● Synchronous pipeline read with self timed late write.
● Registered address, control and data input/output.
● DDR (Double Data Rate) Interface on read and write ports.
● Fixed 4-bit burst for both read and write operation.
● Clock-stop supports to reduce current.
●Two input clocks (K and K) for accurate DDR timing at clock rising edges only.
●Two input clocks for output data (C and C) to minimize clock-skew and flight-time mismatches.
●Two echo clocks (CQ and CQ) to enhance output data traceability.
●Single address bus.
●Byte write (x9, x18, x36) function.
● Separate read/write control pin (R and W)
● Simple depth expansion with no data contention.
