IS43LR16200D

IS43/46LR16200D 1M x 16Bits x 2Banks Mobile DDR SDRAM Description The IS43LR16200D is 33,554,432 bits CMOS Mobile Double Data Rate Synchronous DRAM organized as 2 banks of 1,048,576 words x 16 bits. This product uses a double-data-rate architecture to achieve high-speed operation. The double data rate architecture is essentially a 2N prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. This product offers fully synchronous operations referenced to both rising and falling edges of the clock. The data paths are internally pipelined and 2n-bits prefetched to achieve high bandwidth. All input and output voltage levels are compatible with LVCMOS. Features JEDEC standard 1.8V power supply Two internal banks for concurrent operation MRS cycle with address key programs - CAS latency 2, 3 (clock) - Burst length (2, 4, 8, 16) - Burst type (sequential & interleave) Fully differential clock inputs (CK, /CK) All inputs except data & DM are sampled at the rising edge of the system clock Data I/O transaction on both edges of data strobe Bidirectional data strobe per byte of data (DQS) DM for write masking only Edge aligned data & data strobe output Center aligned data & data strobe input 64ms refresh period (4K cycle) Auto & self refresh Concurrent Auto Precharge Maximum clock frequency up to 166MHz Maximum data rate up to 333Mbps/pin Power Saving support - PASR (Partial Array Self Refresh) - Auto TCS...
