• 1.8V+0.1V/-0.1V Power Supply.
• DLL circuitry for wide output data valid window and future fre-
• I/O Supply Voltage 1.5V+0.1V/-0.1V for 1.5V I/O,
• Separate independent read and write data ports
• 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
• Two input clocks for output data (C and C) to minimize
• Two echo clocks (CQ and CQ) to enhance output data
• Single address bus.
• Byte write (x18, x36) function.
• Separate read/write control pin(R and W)
• Simple depth expansion with no data contention.
• Programmable output impedance.
• JTAG 1149.1 compatible test access port.
• 165FBGA(11x15 ball array) with body size of 13mmx15mm.
• Operating in commercial and industrial temperature range.
