Microchip Technology A42MX09-2TQG176 Embedded FPGA ICs

The Microchip Technology A42MX09-2TQG176 is a high-performance, non-volatile embedded FPGA belonging to the MX series, designed for mission-critical applications demanding reliability, security, and deterministic operation. With 9,000 system gates and housed in a 176-pin Thin Quad Flat Pack (TQFP), this FPGA utilizes anti-fuse technology, making it one-time programmable (OTP) and highly resistant to radiation and environmental disturbances—ideal for aerospace, defense, and industrial automation systems. Unlike SRAM-based FPGAs, the A42MX09-2TQG176 ensures instant-on operation, eliminating configuration delays at power-up. Its low static power consumption (one-fifth of equivalent FPGAs) and high-speed performance (up to 250 MHz clock frequency) make it excellent for real-time control systems, high-speed signal processing, and embedded peripheral interfacing.
