A42MX09-1PLG84I

The A42MX09-1PLG84I is an MX Field Programmable Gate Array (FPGA) IC from Microchip Technology designed for industrial applications. It delivers moderate programmable logic capacity with a large I/O complement in a compact 84‑lead PLCC (J‑lead) surface-mount package.

With support for a wide supply range and an industrial operating temperature window, this device is suited for designs that require flexible power input, reliable operation across temperature extremes, and board-level integration of custom logic and I/O interfacing.

Key Features

• Logic Capacity  Provides 336 logic elements and approximately 14,000 equivalent gates for implementing combinational and sequential logic functions.
• I/O  72 user I/O pins to support multiple peripheral interfaces and broad signal connectivity on a single device.
• Embedded Memory  No on-chip RAM (Total RAM bits: 0); suitable for applications that rely on external memory or do not require significant embedded RAM.
• Supply Voltage  Operates from 3 V to 5.5 V, allowing integration into systems with either 3.3 V or 5 V supply domains.
• Package & Mounting  84‑lead LCC (J‑Lead) surface-mount package; supplier device package listed as 84‑PLCC with nominal dimensions 29.31 × 29.31 mm for compact board-level integration.
• Temperature & Grade  Industrial grade device rated for operation from −40 °C to 85 °C.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Implement control logic, state machines, and interfacing functions in equipment that requires industrial temperature operation.
• I/O Expansion and Interface Bridging  Consolidate multiple peripheral interfaces and glue logic into a single FPGA using the device’s 72 I/O pins.
• Low-Density Programmable Logic  Ideal for implementing moderate-complexity logic blocks, protocol converters, and custom logic where on-chip RAM is not required.

Unique Advantages

• Moderate logic integration: 336 logic elements and ~14,000 gates provide sufficient capacity for a wide range of control and interfacing tasks without excess complexity.
• High I/O count: 72 I/O pins enable consolidation of multiple signals and peripherals, reducing the need for external glue logic.
• Wide supply tolerance: 3 V to 5.5 V operation allows straightforward integration into systems with 3.3 V or 5 V domains.
• Industrial-rated operation: −40 °C to 85 °C rating supports deployment in temperature-challenging environments.
• Compact PLCC packaging: 84‑lead LCC (J‑lead) surface-mount package provides a small footprint option for board-level designs requiring many I/Os.
• RoHS compliant: Meets environmental compliance requirements for lead-free assembly.
