You have three different part types for SRAMs: B3, C5 and D8. How do I<br>

<br>
Each one of these are functionally different. For an in-depth<br>
discussion of this subject, check out Technical Note TN-58-06 (pdf),<br>
"Choosing the Right SyncBurst SRAM." This note describes the reasons why<br>
three different part types are available and the pros and cons of choosing<br>
one over another.<br>
<br>
In brief, the two main differences among the three parts are the<br>
flow-through and pipelined versions. Flow-through devices have an input<br>
register only (B3), and pipelined have an input and output register (C5<br>
and D8). Flow-through devices are the easiest to use when replacing an<br>
asynchronous part or at frequencies below 83 MHz. Pipelined parts are<br>
usually used for faster frequencies (>83 MHz).<br>

Je tam aj link na TN-58-06, v ktorom je to trocha podrobnejsie rozpisane.<br>
<br>
Aj DS z toho Vasho linku (aj z inych podobnych) vyplyva, ze LG je suffix<br>
oznacujuci TQFP-100 puzdro.<br>
