A42MX16-PQ208A

The A42MX16-PQ208A is an MX family field programmable gate array (FPGA) IC from Microchip Technology presented in a 208-pin BFQFP package. It provides a compact, surface-mount programmable-logic solution with 608 logic elements (approximately 24,000 gates) and 140 user I/Os for implementating custom digital functions.

Qualified to AEC-Q100 and rated for an extended operating range, this device is targeted at designs that require automotive-grade reliability, wide voltage tolerance, and a high I/O count in a 28 × 28 mm package footprint.

Key Features

• Core Logic — 608 logic elements (approximately 24,000 gates) for implementing custom logic, glue functions, and small to moderate-scale finite-state machines.
• I/O Density — 140 general-purpose I/O pins to support multiple interfaces, sensor connectivity, and parallel or multiplexed signals at the board level.
• Memory — No on-chip RAM (Total RAM Bits: 0), suitable for applications where external memory or purely combinational/sequential logic is employed.
• Power Supply — Operates from 3 V to 5.25 V, allowing compatibility with common automotive and industrial supply rails.
• Package & Mounting — 208-BFQFP package (supplier device package: 208-PQFP, 28 × 28 mm) in a surface-mount form factor for compact PCB designs.
• Automotive Qualification & Temperature Range — AEC-Q100 qualified and specified for operation from −40 °C to 125 °C for environments requiring extended thermal range and qualification.

Typical Applications

• Automotive control modules — AEC-Q100 qualification and −40 °C to 125 °C rating make the device suitable for in-vehicle control units that need programmable logic and high I/O counts.
• Sensor interfacing and aggregation — 140 I/Os allow direct connection and multiplexing of multiple sensors, enabling aggregation and pre-processing at the board edge.
• Interface bridging and glue logic — Use the FPGA for protocol adaptation, bus bridging, and custom logic between microcontrollers and peripherals with varying voltage domains within the supported supply range.

Unique Advantages

• Automotive-ready qualification: AEC-Q100 certification provides documented qualification for automotive applications requiring component-level assurance.
• Wide operating voltage: 3 V to 5.25 V supply range permits straightforward integration with common automotive and legacy logic voltage rails.
• Extended temperature tolerance: Specified operation from −40 °C to 125 °C supports deployment in thermally demanding environments.
• High I/O capacity in a compact package: 140 I/Os in a 208-pin BFQFP allow dense external connectivity without a larger package footprint.
• Surface-mount package for production-ready PCBs: 28 × 28 mm 208-PQFP footprint simplifies assembly and board-level routing for production environments.
