Overview of AT40K40-2FQC – Field Programmable Gate Array (FPGA), 2,304 logic elements, 18,432-bit RAM, 256 I/O, 304-BFQFP
The AT40K40-2FQC is an SRAM-based FPGA from Microchip Technology designed for high-performance, reconfigurable digital logic. As part of the AT40K series, this device combines 2,304 logic elements with distributed on-chip RAM and a rich I/O complement for mid-range gate-count FPGA applications.
Targeted at systems that require performance and in-system adaptability, the AT40K40-2FQC offers system speeds up to 100 MHz, PCI-compliant I/O capability, and features that support DSP-style coprocessing, multimedia processing, and adaptive logic updates. It operates from a 4.75 V to 5.25 V supply and is specified for commercial temperature operation (0 °C to 70 °C).
Key Features
- Core Performance – Up to 2,304 logic elements (cells) enabling designs in the ~40K–50K usable-gate range; system speeds to 100 MHz and array multipliers >50 MHz as specified for the series.
- Distributed On-Chip RAM (FreeRAM) – Up to 18,432 bits of flexible, 10 ns programmable SRAM that can be instantiated as single- or dual-port, synchronous or asynchronous memory without consuming logic resources.
- I/O and Interface Capability – 256 I/O pins with PCI-compliant I/O support and 3 V/5 V signaling capability in the series; programmable output drive and fast, flexible array access to aid pin locking and board-level integration.
- Clocking and Timing – Eight global clocks with low-skew distribution and programmable edge transitions, plus four additional dedicated PCI clocks for synchronous system designs.
- Reconfigurability – Series-level Cache Logic capability enables dynamic full or partial in-system reconfiguration with unlimited reprogramming via serial or parallel modes for adaptive designs.
- Package and Mounting – Surface-mount 304-BFQFP package (supplier device package: 304-PQFP, 40 × 40 mm) suitable for compact board-level integration.
- Supply and Temperature – 5 V supply range (4.75 V to 5.25 V) and commercial-grade operating temperature from 0 °C to 70 °C.
- Compliance – RoHS-compliant device; series documented as fully PCI-compliant in the datasheet content.
Typical Applications
- DSP Coprocessor – Implement FIR filters, FFTs and other arithmetic accelerators using the device’s array multipliers and distributed RAM for high-throughput signal processing.
- Video and Multimedia Processing – Use on-chip multipliers and fast SRAM to accelerate video compression/decompression, DCT operations, and real-time media algorithms.
- PCI-Based Systems – Integrate as a programmable logic element in PCI-compliant designs where flexible I/O and dedicated PCI clocks simplify board-level interfacing.
- Adaptive and Reconfigurable Systems – Leverage Cache Logic dynamic reconfigurability for systems that require in-field updates or rapid algorithm changes without full device replacement.
Unique Advantages
- Balanced Performance and Capacity: 2,304 logic elements and approximately 18,432 bits of distributed SRAM provide a mid-range gate-count solution for complex logic and embedded memory needs.
- Fast, Deterministic Memory: 10 ns FreeRAM blocks enable low-latency embedded memory implementations for FIFOs, scratch pads, and coefficient storage without consuming logic elements.
- Robust Clocking: Eight global clocks and programmable edge transitions reduce clock distribution challenges and enable low-skew synchronous designs.
- Field Reconfigurability: Series-level support for unlimited serial/parallel reprogramming and partial in-system reconfiguration allows rapid updates and adaptive system behavior.
- Practical Board Integration: 256 I/Os, programmable output drive, and a 304-pin PQFP/BFQFP package simplify routing and signal integrity planning for dense designs.
- Commercial-Grade Reliability: Specified for 0 °C to 70 °C operation and RoHS compliance for mainstream commercial applications.
