LX45 vs LX16 Differences¶
Critical Link offers the MityDSP-L138F family of modules with two different FPGA options, the Spartan 6 LX16 and LX45.
Device specification differences [[http://www.xilinx.com/support/documentation/data_sheets/ds160.pdf]]¶
| Device | Logic Cells | Slices | Flip-Flops | Max Distributed RAM (Kb) | DSP48A1 Slices | Block Ram 18 Kb | Block Ram Max (Kb) | CMT's | Memory Controller Blocks (Max) |
| XC6SLX16 | 14,579 | 2,278 | 18,224 | 136 | 32 | 32 | 576 | 2 | 2 |
| XC6SLX45 | 43,661 | 6,822 | 54,576 | 401 | 58 | 116 | 2,088 | 4 | 2 |
I/O Pin Differences¶
The biggest difference between the LX16 and the LX45 is that the LX45 has (8) I/O's that are not bonded like the LX16. The balls that are not bonded are:
| Module Pin | FPGA Ball |
| 154 | F12 |
| 156 | E12 |
| 158 | D12 |
| 160 | C12 |
| 162 | F11 |
| 164 | E11 |
| 170 | E7 |
| 172 | E8 |
