Architecture Overview

The MachXO2 family architecture contains an array of logic blocks surrounded by Programmable I/O (PIO). The

larger logic density devices in this family have sysCLOCK™ PLLs and blocks of sysMEM Embedded Block RAM

(EBRs). Figures 2-1 and 2-2 show the block diagrams of the various family members.

Note: MachXO2-256, and MachXO2-640/U are similar to MachXO2-1200. MachXO2-256 has a lower LUT count and no PLL or EBR blocks.

MachXO2-640 has no PLL, a lower LUT count and two EBR blocks. MachXO2-640U has a lower LUT count, one PLL and seven EBR blocks.

Note: MachXO2-1200U, MachXO2-2000/U and MachXO2-7000 are similar to MachXO2-4000. MachXO2-1200U and MachXO2-2000 have a lower LUT count,

one PLL, and eight EBR blocks. MachXO2-2000U has a lower LUT count, two PLLs, and 10 EBR blocks. MachXO2-7000 has a higher LUT count, two PLLs,

and 26 EBR blocks.
