A42MX24-FPL84

The A42MX24-FPL84 is an MX series field programmable gate array (FPGA) from Microchip Technology designed for commercial embedded applications that require customizable digital logic and flexible I/O. With up to 36,000 gates and 72 user I/O pins, this surface-mount FPGA supports mid-density logic implementations in a compact 84‑lead PLCC (J‑lead) package.

Its operating range and package profile make it suitable for designs that need a moderate logic capacity, a broad supply voltage window, and RoHS-compliant component sourcing.

Key Features

• Core Logic — 1890 logic elements and 912 logic element cells provide the programmable fabric for implementing custom combinational and sequential logic functions.
• Gate Count — 36,000 gates available to map medium-complexity logic and state machines.
• I/O — 72 general-purpose I/O pins for interfacing to peripherals, sensors, and other system components.
• Memory — No on-chip RAM bits are specified for this device.
• Power — Wide supply voltage range from 3 V to 5.25 V to support designs within common commercial voltage rails.
• Package & Mounting — 84‑lead LCC (J‑lead) / 84‑PLCC supplier package (29.31 × 29.31 mm) in a surface-mount form factor for compact PCB layouts.
• Temperature & Grade — Commercial grade operation over a temperature range of 0 °C to 70 °C.
• Regulatory — RoHS compliant.

Typical Applications

• Embedded control and glue logic — Use the device’s 36,000 gates and 72 I/O to implement custom control logic, timing, and protocol bridging in commercial embedded systems.
• I/O expansion and interface bridging — Leverage the available I/O count to consolidate multiple peripheral interfaces or act as an interface hub between subsystems.
• Prototyping and custom peripheral development — Mid-density logic and PLCC packaging make the device suitable for prototype platforms and custom peripheral implementations in commercial products.

Unique Advantages

• Balanced logic capacity: 36,000 gates with 1890 logic elements provide a mid-range resource set for many commercial digital designs without oversizing the bill of materials.
