Detailed Description

Antifuse FPGA in the MX series with about 6000 internal gates and 34 user I/O in a compact 44-PLCC J-lead package (16.59 x 16.59 mm). Industrial temperature grade for reliable operation from -40°C to +85°C TA. Dual-supply operation supports both 3.0–3.6 V and 4.5–5.5 V systems. Surface-mount, tray-packed. RoHS non-compliant (leaded finish). Main Category Integrated Circuits, Small Classification Embedded – FPGAs. Base product number A40MX04. Quantity on hand 2605.

Key Features

Antifuse one-time programmable FPGA, instant-on, no external configuration memory needed

Approx. 6000 gates for moderate-complexity designs

34 user I/O pins for flexible interfacing

Industrial temperature range -40°C to +85°C TA

Dual supply options 3.0–3.6 V or 4.5–5.5 V

Surface-mount 44-PLCC J-lead package, compact footprint 16.59 x 16.59 mm

MX series architecture with predictable timing and robust reliability

RoHS non-compliant, leaded plating suitable for legacy designs

Key Advantages

Instant-on behavior, ideal for time-critical systems

No external configuration storage, simpler BOM and higher reliability

One-time programmable antifuse technology for strong security and tamper resistance

Deterministic timing and low susceptibility to SEUs compared to SRAM FPGAs

Supports both 3.3 V and 5 V environments for easy retrofit into older systems

Industrial temperature rating for harsh conditions

Proven, mature platform with stable performance

Packaging

Packing type Tray for secure handling and assembly-line flow

Package case 44-PLCC (J-Lead), 16.59 mm x 16.59 mm body

Pin configuration 44 leads, 34 user I/O available, standard PLCC pin pitch

Material Molded epoxy body with metal leadframe; leaded finish (RoHS non-compliant)

Thermal characteristics Industrial ambient operation -40°C to +85°C; use good PCB thermal design and airflow for best results

Electrical properties Dual supply ranges 3.0–3.6 V or 4.5–5.5 V, approx. 6000 gates, 34 I/O, MX series core

Lifecycle

Status Mature technology; availability can vary by package and temperature grade. Not indicated as near discontinuation in this listing, but some MX family parts are limited in supply

Recommended to verify current lifecycle and long-term availability with our sales team

Equivalent or alternative models (verify pinout and system fit before use)

- Same family and similar function A40MX04 variants in different speed grades and operating ranges, for example A40MX04-1PL44 (commercial temp), A40MX04-2PL44I (faster speed grade, industrial temp)

- Lower or higher gate-count options in the MX family A40MX02-PL44 (lower density), A40MX08 (higher density) depending on design needs

- Modern Microchip FPGA families for functional migration IGLOO, ProASIC3, and SmartFusion2 families (not pin-compatible; offer flash-based or SRAM-based configuration, broader tool support, and enhanced features)

If you need a pin-compatible drop-in or an exact alternative and do not see it listed, contact our sales team via the Y-IC website for detailed cross-references and lifecycle guidance
