AT40K05AL-1BQC

The AT40K05AL-1BQC is an SRAM-based FPGA from Microchip Technology in the AT40KAL family. It provides a compact, surface-mount 144-LQFP package with 114 I/O and approximately 2,048 bits of distributed on-chip SRAM, suitable for commercial-grade embedded designs operating at 3.0–3.6 V.

Designed for high-performance configurable logic, the device targets applications that require on-chip RAM, reconfigurability and fast arithmetic blocks—delivering system speeds up to 100 MHz and array multipliers operating above 50 MHz as documented for the AT40KAL series.

Key Features

• Core Architecture and Performance  SRAM-based AT40KAL family architecture with documented system speeds to 100 MHz and array multipliers >50 MHz.
• Logic Capacity  256 logic elements (cells) providing approximately 10,000 usable gates for mid-range logic implementations.
• On-Chip Memory (FreeRAM)  Distributed, flexible 10 ns SRAM with approximately 2,048 bits of embedded memory supporting single- or dual-port, synchronous or asynchronous operation.
• I/O and Drive  114 I/O pins in the 144-LQFP package; datasheet notes programmable output drive and documented I/O counts in the family.
• Clocking  Eight global clocks with low-skew distribution and additional dedicated PCI clock resources provided in the AT40KAL family.
• Dynamic Reconfiguration  Cache Logic capability for full or partial in-system reconfigurability and unlimited re-programmability via serial or parallel modes (AT40KAL family feature).
• Package & Mounting  144-LQFP (20×20) surface-mount package, commercial grade; operating temperature range 0 °C to 70 °C.
• Power and I/O Tolerance  Supply range 3.0 V to 3.6 V; AT40KAL family documentation indicates 3.3 V supply and 5 V I/O tolerance.
• Compliance  RoHS compliant.

Typical Applications

• Digital Signal Processing (DSP) and Acceleration  Implement adaptive FIR filters, FFTs and vector multipliers using the device’s fast array multipliers and on-chip SRAM.
• Multimedia and Video Processing  Useful for video compression/decompression functions (DCT, convolution) where in-system reconfiguration and on-chip memory accelerate coefficient updates.
• Encryption and Secure Processing  Hardware-accelerated arithmetic and reconfigurable logic enable custom encryption and data-processing coprocessor functions.
• Custom Logic and I/O Control  Mid-density gate count and 114 I/O make the device suitable for glue logic, protocol bridging and user-interface control in commercial embedded systems.

Unique Advantages

• Flexible On-Chip Memory: FreeRAM provides 2,048 bits of distributed SRAM usable independently of logic cells for FIFOs, scratchpads and coefficient storage.
• Fast Arithmetic Support: Array multipliers documented above 50 MHz enable high-speed multiply and DSP kernels without external accelerators.
• In-System Reconfigurability: Cache Logic gives the ability to perform partial or full reconfiguration in-system and supports unlimited re-programmability via serial or parallel modes.
• Compact, High-I/O Package: 144-LQFP package delivers 114 I/O in a space-efficient surface-mount footprint for board-level integration.
• Commercial-Grade and RoHS Compliant: Designed for commercial temperature ranges (0 °C to 70 °C) and compliant with RoHS requirements.
• 3.0–3.6 V Supply with 5 V I/O Tolerance: Enables 3.3 V system designs while providing tolerance for 5 V I/O signaling as documented for the family.
