A42MX36-1CQ208B

The Microchip Technology A42MX36-1CQ208B is a flash-based field-programmable gate array from the MX family, delivering 36,000 system gates of reprogrammable logic in a 208-lead ceramic quad flat pack. This device integrates non-volatile flash cells that hold configuration data without external boot memory, enabling instant-on operation and eliminating the configuration bitstream vulnerability common in SRAM-based FPGAs. The fine-grained architecture supports a wide range of glue logic, interface bridging, and state machine functions, while the single-chip solution reduces board space and power sequencing complexity. The ceramic package provides a hermetic, thermally stable enclosure suited for high-reliability environments where mechanical shock, vibration, and temperature extremes are routine.

Typical deployments include aerospace flight control modules, military avionics, satellite bus interfaces, and industrial motor drives that demand deterministic power-up behavior and long-term functional integrity. The MX family is frequently selected for secure communication and cryptographic processing applications because the on-chip flash makes bitstream extraction significantly more difficult. For procurement and design teams, the CQFP construction and part number suffix indicate an industrial or extended-temperature grade device; verifying the exact screening level, temperature range, and lead finish against the bill of materials is essential when specifying for mission-critical programs. Although this is a mature product line, Microchip Technology maintains long lifecycle support through its legacy Actel portfolio, and sourcing through authorized channels helps mitigate obsolescence risk and ensure traceability required by defense and aerospace standards.
