Column address: A0~A8.20, 21 BS0, Bank Select Select bank to activate during row address latch time, or bank toBS1 read/write during address latch time.2, 4, 5, 7, 8, DQ0~ Data Input/Output Multiplexed pins for data output and input.10,11, 13, 42, DQ1544,45, 47, 48,50, 51, 5319 CS# Chip Select Disable or enable the command decoder. When command decoder isdisabled, new command is ignored and previous operation continues.18 RAS# Row Address Strobe Command input. When sampled at the rising edge of the clock,RAS#, CAS# and WE# define the operation to be executed.17 CAS# Column Address Strobe Referred to RAS#16 WE# Write Enable Referred to RAS#15, 39 UDQM/ input/output mask The output buffer is placed at Hi-A (with latency of 2) when DQM isLDQM sampled high in read cycle. In write cycle, sampling DQM high willblock the write operation with zero latency.38 CLK Clock Inputs System clock used to sample inputs on the rising edge of clock.37 CKE Clock Enable CKE controls the clock activation and deactivation. When CKE is low,Power Down mode, Suspend mode, or Self Refresh mode is entered.1, 14, 27 Vcc Power (+3.3V) Power for input buffers and logic circuit inside DRAM.28, 41, 54 Vss Ground Ground for input buffers and logic circuit inside DRAM.3, 9, 43, 49 VccQ Power (+3.3V) for I/O buffer Separated power from Vcc, used for output buffers to improve noise.6, 12, 46, 52 VssQ Ground for I/O buffer Separated ground from Vss, used for output buffers to improve noise.36, 40 NC No Connection No Connection16 VDD1Vss15 Q112DATA14 Q103CLOCK13 Q94Q012 Q85Q111 Q76Q210 Q6Q57Q398Q4Control Circuit12-Bit Shift RegisterLatchOutput Buffer(Open Drain)6 5 41 2 3www. xiaoyu163. comQQ 376315150 992894298TEL 13942296513 992894298051513673QQTEL 13942296513 QQ 376315150 892498299TEL 13942296513 QQ 376315150 892498299http://www.xiaoyu163.comhttp://www.xiaoyu163.com
