K7J321882M
1Mx36-bit, 2Mx18-bit DDR II SIO b2 SRAM
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
.
Separate independent read and write data ports
HSTL I/O
Synchronous pipeline read with self timed late write.
Registered address, control and data input/output.
Full data coherency, providing most current data.
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 aray FBGA) with body size of 15x17mm
