FEATURES

• 1.8V+0.1V/-0.1V Power Supply.
• DLL circuitry for wide output data valid window and future freguency 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.
• Pipelined, double-data rate operation.
• Common data input/output bus .
• 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 2-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 (x18, x36) function.
• Simple depth expansion with no data contention.
• Programmable output impedance.
• JTAG 1149.1 compatible test access port.
• 165FBGA(11x15 ball array FBGA) with body size of 13x15mm
