Detailed Description

MX series one-time programmable FPGA

Approx 6000 system gates with 69 user I or O

Industrial temperature grade -40 to 85 degrees C

Surface-mount 84-PLCC J-lead package 29.31 mm x 29.31 mm

Operates from either 3.0 to 3.6 V or 4.5 to 5.5 V supplies

RoHS non-compliant legacy device, tin lead finish typical

Supplier device package 84-PLCC

Base product number A40MX04

Key Features

One-time programmable non-volatile architecture instant on no external configuration memory

Dual supply options 3.3 V or 5 V for easy legacy system drop-in

69 I or O pins for moderate connectivity in control and glue logic

Deterministic timing and robust EMI immunity typical of antifuse style devices

Industrial temperature range -40 to 85 degrees C for harsh environments

Proven MX family with long field history and stable performance

Key Advantages

No boot time or configuration vulnerability for better startup reliability

Simple power architecture supports both modern 3.3 V and classic 5 V systems

Stable across temperature with predictable timing behavior

Ideal for sustaining and servicing legacy designs where requalification risk must be minimized

Lower maintenance since configuration cannot be altered in the field

Packaging

Type PLCC 84-pin J-lead LCC surface mount

Material Molded plastic body with copper alloy J-leads tin lead finish common for legacy parts

Size 29.31 mm x 29.31 mm nominal body dimensions

Pin configuration 84 total pins with 69 user I or O remaining pins assigned to power ground and dedicated pins typical PLCC pitch 1.27 mm

Thermal characteristics Industrial grade operation -40 to 85 degrees C no exposed thermal pad heat is conducted through leads and PCB copper use good layout for thermal spreading

Electrical properties Supply 3.0 to 3.6 V or 4.5 to 5.5 V typical core and I or O compatibility device is instant on and non-volatile number of gates about 6000

Lifecycle

Status Mature legacy product and RoHS non-compliant variants may have limited availability in some regions

Not currently listed as a new design recommendation check availability per lot and date code

Potential alternatives from Microchip for new designs not pin compatible

- A40MX02 and A40MX08 MX family lower and higher density options in similar package families

- A42MX and A54SX families for antifuse style continuity in select packages

- ProASIC3 series A3P060 A3P125 A3P250 flash-based FPGAs 3.3 V instant on reprogrammable

- IGLOO and IGLOO2 families low-power flash FPGAs various densities and packages

- SmartFusion2 for FPGA plus ARM Cortex-M3 if integration is desired

Important note Alternatives differ in architecture timing tools and pinout verify with datasheets and your design requirements
