AT40K40-2EQI

The AT40K40-2EQI from Microchip Technology is an SRAM-based field programmable gate array (FPGA) in the AT40K family, designed for high-performance, reconfigurable logic. This device combines 2,304 logic elements with approximately 18,432 bits of distributed on-chip RAM, 193 general-purpose I/Os and support for system clocking to meet demanding DSP, coprocessor and multimedia processing tasks.

Built for industrial environments, the AT40K40-2EQI delivers a mix of embedded memory, fast arithmetic capability and flexible I/O in a 240-BFQFP surface-mount package, enabling use in applications that require in-system reprogrammability and reliable operation across a wide temperature and supply range.

Key Features

• Logic Capacity – 2,304 logic elements (cells) supporting designs up to approximately 50,000 gates, suitable for mid-range FPGA implementations.
• Embedded Memory (FreeRAM) – Approximately 18,432 bits of distributed 10 ns SRAM that can be instantiated as single- or dual-port, synchronous or asynchronous RAM for FIFOs, scratch pads and coefficient storage.
• High-Performance Arithmetic – Architecture supports ultra-fast array multipliers (array multipliers > 50 MHz) and system speeds to 100 MHz for compute-intensive functions.
• I/O – 193 I/Os with 3V/5V capability and programmable output drive; the AT40K family provides PCI-compliant I/O signaling and fast, flexible array access for pin locking and interface control.
• Clocking – Eight global clocks with low-skew distribution, programmable edge selection and distributed clock shutdown for power management; four additional dedicated PCI clocks are available in the family.
• Reconfigurability – Cache Logic dynamic partial/full re-configurability enables in-system updates and adaptive designs without loss of stored data; unlimited re-programmability via serial or parallel configuration modes.
• Package & Mounting – 240-BFQFP (supplier device package: 240-PQFP 32×32) surface-mount package for density and manufacturability.
• Industrial Grade & Environmental – Rated for industrial operation with an operating temperature range of -40°C to 85°C and RoHS compliance.
• Power – Designed for 5 V class systems with a specified supply range of 4.5 V to 5.5 V.

Typical Applications

• DSP and Signal Processing – Implement FIR filters, FFTs, convolvers and other compute-heavy blocks where on-chip FreeRAM and fast array multipliers improve throughput and latency.
• Multimedia & Video – Use as a coprocessor for video compression/decompression, DCT and interpolation tasks that benefit from dense arithmetic and embedded memory.
• Encryption & Secure Processing – Implement algorithm accelerators and crypto primitives using the device’s logic and RAM resources for hardware-accelerated security functions.
• High-speed Interfaces – Leverage the device’s 193 I/Os with 3V/5V capability and PCI-compliant signaling for complex peripheral and board-level interfacing.

Unique Advantages

• Reconfigurable In-System Logic: Cache Logic enables dynamic full or partial reconfiguration so designs can be updated or tuned without removing the device from the system.
• Embedded, Fast SRAM: Distributed 10 ns FreeRAM provides flexible single/dual-port memory blocks that conserve logic resources and accelerate data buffering and coefficient storage.
• Balanced Performance: Combines 2,304 logic elements, fast multipliers and up to 100 MHz system speed to support compute-intensive and mixed-signal interfacing tasks.
• Industrial Reliability: Industrial temperature rating (-40°C to 85°C) and RoHS compliance support deployment in industrial-grade applications and regulations-aware manufacturing.
• Flexible I/O and Clocking: Extensive I/O count with programmable drive and eight global clocks simplify system-level integration for PCI and other high-speed interfaces.
