Key Features

6000-gate density for compact logic designs

69 user I/O for flexible external connectivity

84-PLCC plastic leaded chip carrier with J-leads

Wide temperature operation: −55°C to +125°C (TC)

Dual-voltage supply ranges: 3.0–3.6 V and 4.5–5.5 V

Surface-mount assembly; tray packaging for production

Supplier device package size: 29.31 mm × 29.31 mm

Series: MX; base product number: A40MX04

RoHS non-compliant construction, suitable for sustaining legacy designs

Key Advantages

Reliable in harsh environments due to extended temperature range

Compatible with both 3.3 V and 5 V system rails

Stable platform for long-life industrial, aerospace, and legacy programs

PLCC J-leads offer mechanical compliance and easier rework than many flat-pack options

Ideal for drop-in sustainment of existing boards without redesign

Packaging

Type: 84-PLCC plastic leaded chip carrier (also referred to as 84-LCC, J-lead)

Material: Molded plastic body; copper alloy J-leads with traditional tin‑lead finish (non‑RoHS)

Size: 29.31 mm × 29.31 mm body; square form factor

Pin configuration: 84 perimeter J‑leads; typical lead pitch ~1.27 mm; pin 1 notch for orientation

Thermal characteristics: Rated case temperature −55°C to +125°C; use appropriate derating, airflow, and thermal design; consult datasheet for thermal resistance

Electrical properties: Supply 3.0–3.6 V or 4.5–5.5 V; 69 I/O; 6000 gates; series MX; mounting type surface mount; supplier device package 84‑PLCC; shipment in trays

Lifecycle

Status: Legacy product; availability can be limited; many variants are NRND/EOL in some regions

Best use: Sustainment or replacement in existing platforms; evaluate lifecycle risk for new designs

Equivalent or alternative models (same MX family; verify fit and specifications):

- A40MX02 (lower density)

- A40MX05 (higher density)

- A40MX08 (higher density)

Modern Microchip alternatives (not pin‑to‑pin; redesign required):

- ProASIC3 (e.g., A3P030, A3P060) for 3.3 V systems

- IGLOO (e.g., AGL060) for low-power 3.3 V applications

- SmartFusion2 (e.g., M2S050) for enhanced security and mixed‑signal integration

- RTG4 / RTAX families for radiation‑tolerant aerospace use
