The Module contains sixteeen (16) Synchronous Burst RAM devices, packaged in the industry standard JEDEC 14mmx20mm TQFP placed on a Multilayer FR4 Substrate. The Module Architecture is defined as a Sync/SyncBurst, FlowThrough, with support for either linear or sequential burst. This Module provides high performance, 2-1-1-1 accesses when used in Burst Mode, and when used in Synchronous Only Mode, provides a high performance cost advantage over BiCMOS asynchronous device architectures. 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 34 35 36 37 38 39 40 41 42 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 VSS A17 A1 A15 A3 VCC A13 A5 A11 A7 VSS A9 A18 E1 E3 VSS CLK VSS G BWE VCC BW2 BW1 BW6 BW5 VSS ADV VSS DQP0 VCC DQ7 DQ6 DQ5 DQ4 VSS DQP1 VCC DQ15 DQ14 DQ13 DQ12 VSS NC VCC DQ16 DQ17 DQ18 DQ19 VSS ZZ2 VCC DQ24 DQ25 DQ26 DQ27 VSS NC VCC DQ32 DQ33 DQ34 DQ35 VSS ZZ3 VCC DQ40 DQ41 DQ42 DQ43 VSS NC VCC DQ48 DQ49 DQ50 DQ51 VSS ZZ4 VCC DQ56 DQ57 DQ58 DQ59 VSS 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 PIN DESCRIPTION DQ0 - DQ63 Input/Output Bus DQP0 - DQP7 Parity Bits Synchronous Only operations are performed via strapping ADSC Low, and ADSP/ADV High, which provides for Ultra Fast Accesses in Read Mode while providing for internally self-timed Early Writes. A0 - A18 Address Bus EM Module Enable E1, E2, E3, E4 Synchronous Bank Enables BWE Byte Write Mode Enable Synchronous/Synchronous Burst operations are in relation to an externally supplied clock, Registered Address, Registered Global Write, Registered Enables as well as an Asynchronous Output Enable. This Module has been defined with full flexibility, which allows individual control of each of the eight bytes, as well as Quad Words in both Read and Write Operations.
