EDD5108ADTA-LI

DATA SHEET 512M bits DDR SDRAM WTR (Wide Temperature Range) EDD5108ADTA-LI (64M words × 8 bits) EDD5116ADTA-LI (32M words × 16 bits) Description The EDD5108AD and the EDD5116AD are 512M bits Double Data Rate (DDR) SDRAM. Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 2 bits prefetch-pipelined architecture. Data strobe (DQS) both for read and write are available for high speed and reliable data bus design. By setting extended mode register, the on-chip Delay Locked Loop (DLL) can be set enable or disable. Pin Configurations /xxx indicates active low signal. 66-pin Plastic TSOP(II) VDD VDD DQ0 DQ0 VDDQ VDDQ NC DQ1 DQ1 DQ2 VSSQ VSSQ NC DQ3 DQ2 DQ4 VDDQ VDDQ NC DQ5 DQ3 DQ6 VSSQ VSSQ NC DQ7 NC NC VDDQ VDDQ NC LDQS NC NC VDD VDD NC NC NC LDM /WE /WE /CAS /CAS /RAS /RAS /CS /CS NC NC BA0 BA0 BA1 BA1 A10(AP) A10(AP) A0 A0 A1 A1 A2 A2 A3 A3 VDD VDD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 VSS VSS DQ15 DQ7 VSSQ VSSQ DQ14 NC DQ13 DQ6 VDDQ VDDQ DQ12 NC DQ11 DQ5 VSSQ VSSQ DQ10 NC DQ9 DQ4 VDDQ VDDQ DQ8 NC NC NC VSSQ VSSQ UDQS DQS NC NC VREF VREF VSS VSS UDM DM /CK /CK CK CK CKE CKE NC NC A12 A12 A11 A11 A9 A9 A8 A8 A7 A7 A6 A6 A5 A5 A4 A4 VSS VSS EO Features Power supply: VDD, VDDQ = 2.5V ± 0.2V Data Rate: 333Mbps/266Mbps (max.)
