Detailed Description

Antifuse, one-time-programmable FPGA from the MX series

6000 system gates and 34 user I/O

44-PLCC J-leaded package, 16.59 x 16.59 mm body

Dual-supply operation options — 3.0 to 3.6 V or 4.75 to 5.25 V

Commercial temperature range 0 to 70 C

RoHS3 compliant, surface-mount, tray packing

Base product number A40MX04, speed grade -1

Key Features

Nonvolatile antifuse technology — instant-on at power-up, no external configuration memory

6000-gate density with 34 I/O for glue logic, interfaces, and control

Operates from either 3.3 V or 5 V rails

44-PLCC (J-lead) footprint for robust SMT assembly and easy rework

MX family architecture with proven reliability in legacy and long-life systems

Commercial temperature range 0 to 70 C

RoHS3 compliant device

Key Advantages

Instant-on behavior — deterministic startup with no bitstream load time

High security — antifuse technology is inherently resistant to readback and cloning

Simplified BOM — no external configuration flash or supervisor required

3.3 V and 5 V operation options simplify use in mixed-voltage systems

Stable long-term behavior and low soft-error susceptibility versus SRAM FPGAs

Compact PLCC package eases replacement in existing designs and field repairs

Packaging

Shipment format — Tray

Device package type — 44-PLCC (also called 44-LCC with J-leads)

Package body size — 16.59 mm x 16.59 mm nominal

Lead style and pitch — J-leads, typical PLCC pitch 1.27 mm

Pin configuration — 44 pins total with approximately 34 user I/O, remaining pins for power and ground, test, and control

Materials and finish — Molded plastic body, RoHS-compliant lead finish

Mounting — Surface mount, compatible with standard Pb-free reflow profiles

Thermal characteristics — Commercial ambient 0 to 70 C; heat removal mainly via leads and PCB copper; follow standard PLCC land pattern and copper pour practices for best thermal performance

Electrical highlights — Core powered by either 3.0 to 3.6 V or 4.75 to 5.25 V as specified; I/O count 34; nonvolatile antifuse configuration

Lifecycle

Status — Mature legacy product family. Availability can be limited and lead times may vary. Not generally recommended for brand-new, high-volume platforms without a lifecycle review.

Direct equivalents — Variants of A40MX04 may exist in other packages or speed grades. Pin-to-pin alternatives within the same MX family depend on package and speed. Please verify footprint and timing before substitution.

Parametric or migration alternatives from Microchip — ProASIC3 (flash-based), IGLOO/IGLOO2 (low power), SmartFusion2 (FPGA plus MCU), PolarFire (mid-range). These are not pin compatible but can replace functionality in new designs.
