FEATURES
FUNCTIONAL BLOCK DIAGRAM
2.5V+0.1V/-0.1V Power Supply.
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.
Single address bus.
Byte writable function.
Sepatate 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 aray FBGA) with body size of 13x15mm
