AT40K40AL-1DQC

The AT40K40AL-1DQC is an SRAM-based FPGA in the AT40KAL family from Microchip Technology, packaged in a 208-BFQFP surface-mount device. It provides 2,304 logic elements (cells), approximately 18,432 bits of embedded RAM and 161 I/O pins for mid-density, reconfigurable digital designs.

Targeted at commercial applications that require reprogrammable logic, on-chip memory and DSP-style acceleration, this device combines fast, distributed 10 ns FreeRAM, multi-clock capability and in-system reconfiguration to support adaptive, performance-oriented designs.

Key Features

• Core Density  2,304 logic elements (cells) and a usable gate count in the AT40KAL family suitable for designs in the 40K–50K gate range.
• Embedded Memory (FreeRAM)  Approximately 18,432 bits of distributed, flexible SRAM that supports single/dual-port, synchronous or asynchronous configurations with 10 ns access.
• High I/O Count  161 programmable I/O pins with selectable output drive characteristics for flexible interfacing to external logic and subsystems.
• Clocking  Up to 8 global clocks with low-skew distribution, programmable edge transitions and distributed clock shutdown for power management.
• Reconfigurability (Cache Logic)  Dynamic full or partial in-system reconfiguration capability enabling adaptive designs and rapid vector or coefficient updates without losing stored data.
• Performance  Family-level characteristics include system speeds to 100 MHz, array multipliers >50 MHz and internal 10 ns SRAM enabling DSP-friendly implementations.
• Supply and I/O Tolerance  Operates from 3.0 V to 3.6 V and is specified as 5 V I/O tolerant per the AT40KAL family documentation.
• Package & Mounting  208-BFQFP (supplier package 208-PQFP, 28×28) surface-mount package for industry-standard board assembly.
• Commercial Grade & Compliance  Commercial operating temperature range 0 °C to 70 °C and RoHS-compliant.

Typical Applications

• DSP Acceleration: Used as a coprocessor for FIR filters, FFTs, convolvers and other arithmetic functions where on-chip multipliers and distributed SRAM accelerate computation.
• Video & Multimedia Processing: Implements coefficient-heavy functions such as DCTs, interpolators and compression engines benefitting from fast array multipliers and FreeRAM.
• Communications & Protocol Handling: Provides reconfigurable I/O and multi-clock support for protocol offload, packet processing and flexible interface logic.
• Prototyping and Adaptive Systems: Dynamic partial/full reconfiguration allows rapid iteration and in-field feature updates without losing running-state data.

Unique Advantages

• In-system Reconfigurability: Cache Logic enables full or partial dynamic reconfiguration to update functionality or coefficients without system downtime.
• Integrated, Distributed SRAM: FreeRAM provides many independent 10 ns SRAM blocks that preserve logic resources and simplify buffer/FIFO and scratch-pad implementations.
• DSP-Ready Architecture: Fast array multipliers and high-speed internal memory make the device well suited for compute-intensive signal-processing tasks.
• Flexible Clocking: Eight global clocks with programmable edge control and clock shutdown support complex timing and power-optimized designs.
• High I/O Density in a Standard Package: 161 I/Os in a 208-BFQFP package offers a balance of connectivity and board-level compatibility for mid-density applications.
• Commercial Temperature & RoHS Compliance: Commercial operating range (0 °C to 70 °C) and RoHS compliance simplify sourcing and regulatory considerations for commercial products.
