512Kx36 & 1Mx18 DDRII+ CIO b2 SRAM
512Kx36-bit, 1Mx18-bit DDRII CIO b2 SRAM
FEATURES
• 1.8V+0.1V/-0.1V Power Supply.
• DLL circuitry for wide output data valid window and future freg-
uency scaling.
• I/O Supply Voltage 1.5V+0.1V/-0.1V
• 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.
• Read latency : 2.5 clock cycles
• 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 echo clocks (CQ and CQ) to enhance output data
traceability.
• Data Valid pin(QVLD) supported
• Single address bus.
• Byte write (x18, x36) function.
• Simple depth expansion with no data contention.
• Programmable output impedance(ZQ).
• JTAG 1149.1 compatible test access port.
• 165FBGA(11x15 ball aray FBGA) with body size of 15x17mm
