AT40K40LV-3BQI

The AT40K40LV-3BQI from Microchip Technology is a field programmable gate array (FPGA) designed for moderate-density, industrial-grade embedded logic applications. It provides a balance of configurable logic, on-chip memory, and I/O resources suited to custom control, interfacing, and intermediate-complexity signal processing tasks.

With support for 3.0 V to 3.6 V supply voltages, a surface-mount 144-LQFP package, and an industrial operating range, this device targets applications that require reliable operation across typical industrial temperature conditions.

Key Features

• Logic Capacity — 2304 logic elements (LEs) providing programmable logic resources to implement custom finite state machines, glue logic, and moderate-complexity datapaths.
• On-Chip Memory — 18,432 bits of total RAM for buffering, small FIFOs, and register storage directly within the FPGA fabric.
• I/O Count — 114 user I/O pins to support multiple external interfaces and parallel connections without immediate need for external bus drivers.
• Gate Equivalent — Approximately 50,000 gates of logic capacity to convey relative device scale for system partitioning and integration planning.
• Power Supply Range — Operates from 3.0 V to 3.6 V, enabling compatibility with common 3.3 V system rails.
• Package & Mounting — 144-LQFP surface mount package (supplier device package listed as 144-TQFP, 20×20), suitable for compact PCB layouts.
• Industrial Temperature Grade — Rated for operation from −40 °C to 85 °C for deployment in industrial environments.
• RoHS Compliant — Conforms to RoHS requirements for lead-free manufacturing and environmental compliance.

Typical Applications

• Industrial Control — Implement custom control logic and I/O conditioning using 2304 logic elements and 114 I/O pins to interface with sensors, actuators, and fieldbus peripherals.
• Data Buffering and Protocol Bridging — Use the on-chip 18,432 bits of RAM for small buffers, FIFOs, or as temporary storage when translating between interfaces.
• Embedded System Glue Logic — Replace discrete glue components and CPLDs with programmable logic to consolidate board-level control and simplify BOMs.

Unique Advantages

• Moderate Logic Density: 2304 logic elements deliver sufficient programmable resources for medium-complexity designs without excessive area or cost.
• Integrated Memory: 18,432 bits of embedded RAM reduce reliance on external memory for small buffering and control data.
• High I/O Count: 114 I/O pins allow direct connections to multiple peripherals and parallel interfaces, minimizing external interfacing components.
• Industrial Temperature Range: Rated from −40 °C to 85 °C to meet environmental requirements of industrial deployments.
• Standard 3.3 V Supply: 3.0 V to 3.6 V operation aligns with common system rails for straightforward power integration.
• Compact SMD Package: 144-LQFP (supplier 144-TQFP 20×20) enables dense PCB layouts while maintaining manufacturability with surface-mount assembly.
