Features

* The ICSI IC43R16800 is a four bank DDR DRAM organized as 2 banks x 4Mbit x 16. The IC43R16800 achieves high speed data transfer rates by employing a chip architecture that prefetches multiple bits and then synchronizes the output data to a system clock. All of the control, address, circuits are syn

Applications

* The default value of the mode register is not defined, therefore the mode register must be written after EMRS setting for proper DDR SDRAM operation. The mode register is written by asserting low on CS, RAS, CAS, WE and BA0 (The DDR SDRAM should be in all bank precharge with CKE already high prior
