Logic cellsUnconfirmed dataNot confirmed
Conditions

No architecture-neutral logic-cell count is established. The vendor's nominal LUT4 quantity is retained with its precision and source in lut4_nominal, not converted into AMD logic cells.

65600 logic cellsDS180 ↗ · devicep. 4, Table 6, XC7K70T row; Logic Cells column
Conditions

Vendor metric; not comparable to another architecture's ALMs.

6-input LUTsUnconfirmed dataNot confirmed
Conditions

ECP5 uses LUT4 primitives. Wider logic functions can combine LUT4s, but that is not a source-defined native LUT6 count.

41000 LUT6DS180 ↗ · derivedp. 4, Table 6, XC7K70T row; note 1; p. 7 CLBs, Slices, and LUTs
Conditions

Block RAM capacityDifferent1944 KbLATTICE_ECP5_DS_02012_3_4 ↗ · devicep. 12, Table 1.1, LFE5UM-45 device column, Embedded Memory (kb) row
Conditions

Source reports embedded memory in kb (kilobits), excluding the separate Distributed RAM Bits row; each EBR is 18 kb.

4860 KbDS180 ↗ · devicep. 4, Table 6, XC7K70T row; Block RAM Max (Kb) column
Conditions

Source unit retained: Kb means kilobits, not kilobytes.

36 Kb block RAM blocksUnconfirmed dataNot confirmed
Conditions

The generic field means 36 Kb blocks. ECP5 sysMEM EBR blocks are 18 Kb; sysmem_18kb_blocks retains their physical granularity. No artificial 36 Kb block count is supplied.

135 blocksDS180 ↗ · devicep. 4, Table 6, XC7K70T row; Block RAM 36 Kb column; note 3
Conditions

Each fundamental block is 36 Kb; may be configured as two 18 Kb blocks.

DSP slicesUnconfirmed dataNot confirmed
Conditions

The generic application field denotes DSP slices. The directly printed native count is 18 x 18 multipliers, retained in embedded_18x18_multipliers; separately derived sysDSP slice/block counts retain their own native definitions.

240 DSP48E1DS180 ↗ · devicep. 4, Table 6, XC7K70T row; DSP Slices column; note 2
Conditions

DSP48E1 architecture; counts must not be treated as cross-vendor equivalent.

Lattice LUT4s (nominal)Unconfirmed data44000 LUT4 (nominal)LATTICE_ECP5_DS_02012_3_4 ↗ · derivedp. 12, Table 1.1, LFE5UM-45 device column, LUTs (k) row; p. 16 section 2.2.1 and Table 2.1
Conditions

Manufacturer reports 44 k LUTs in Table 1.1, normalized as k x 1000 for the numeric field. Native primitive is LUT4 (p. 16). This is a nominal vendor figure, not a verified exact physical LUT count or an AMD logic-cell equivalent; do not use density code 45F as the count.

Lattice 18 × 18 multipliersUnconfirmed data72 18 x 18 multipliersLATTICE_ECP5_DS_02012_3_4 ↗ · devicep. 12, Table 1.1, LFE5UM-45 device column, 18 x 18 Multipliers row; p. 29 section 2.9.2; p. 33 Table 2.7
Conditions

Directly printed multiplier count. One sysDSP slice supports two 18 x 18 multipliers (or four 9 x 9); one physical sysDSP block contains two slices (TN-02205-1.3 p. 6). This number is not a DSP-slice/block count and is not equivalent to AMD DSP48E1.

Conditions

Derived as DS-02012 multiplier count / 4: two 18-bit multipliers per slice, two slices per block. A DSP block is not a DSP slice.

Conditions

The package-specific SerDes Channels/I/O Count cell gives exposed channels. Table 2.14 counts duals (two channels per dual); the pin-summary SerDes row counts pins, not channels.

Comparison is not replacement approval.

Check pinout, bank voltages, configuration, tool support, timing, thermal design and lifecycle before changing a part. Different vendors’ logic and DSP counts need architecture-specific interpretation.
