6000-gate MX FPGA in a 68-pin PLCC
The Microchip A40MX04-PLG68 is an MX-series field-programmable gate array with 6000 usable gates and 57 user-configurable I/O lines, supplied in a 68-pin PLCC package. This is a glue-logic FPGA for low-density, non-volatile designs where the PLCC footprint saves board area compared to a QFP or BGA.
With 57 I/O available, the A40MX04-PLG68 suits designs needing moderate pin count for address decoding, state machines, or simple bus interfaces. The 3.0 V supply means the I/O banks are 3.3 V-tolerant but not 5 V-tolerant without external level shifting — check the input thresholds against your upstream logic family. The PLCC-68 package has a 0.050-inch pitch and J-bend leads, which are easier to hand-solder than QFPs but require a PLCC socket or a specific footprint for reflow.
This is a stable BOM line for ongoing builds and new designs that fit the gate-count and temperature constraints.
