ACTEL AX1000-CQ352M

The ACTEL AX1000-CQ352M is an Axcelerator family antifuse FPGA from Actel (Microsemi / Microchip), offering 612,000 equivalent system gates in a 352-pin ceramic CQFP hermetic package, rated for military M-grade operation from –55°C to +125°C. As the standard speed grade variant of the AX1000 series, it delivers the full capability of Actel’s highest-performance antifuse architecture — SEU immunity, FuseLock security, and Live At Power-Up operation — at an accessible entry point for military and aerospace embedded logic programs.

AX1000-CQ352M Architecture: Axcelerator Antifuse on 0.15µm 7-Layer Metal Process

The ACTEL AX1000-CQ352M is built on Actel’s 0.15µm 7-layer metal CMOS antifuse process, delivering 612,000 equivalent system gates and 12,096 SuperCluster logic cells. Its chip-wide highway routing architecture provides deterministic, predictable timing closure that is especially valuable in high-reliability military designs where timing variability across temperature and voltage must be tightly controlled. The device includes 165 Kbits of embedded SRAM with integrated FIFO control logic and segmentable clock networks for efficient, high-reliability clock distribution. FuseLock security technology permanently disables design readback and prevents IP cloning or reverse engineering after programming.

AX1000-CQ352M Package, I/O Standards, and Military Qualification

The ACTEL AX1000-CQ352M is housed in a 352-pin ceramic CQFP hermetic package, providing robust protection against moisture, thermal shock, vibration, and chemical exposure across the full military M-grade temperature range of –55°C to +125°C. Its multi-standard I/O architecture supports LVDS at 700 Mb/s, HSTL, SSTL2/3, GTL+, and PCI/PCI-X — covering the high-speed interface requirements of modern military backplane, communications, and sensor processing designs. The CQ352M package footprint is pin-compatible with the AX1000-1CQ352M, enabling straightforward migration between speed grades without PCB redesign.

AX1000-CQ352M vs AX1000-1CQ352M: Selecting the Right Speed Grade

For engineers comparing the AX1000-CQ352M and AX1000-1CQ352M, the core architecture, gate density, SRAM resources, I/O standards, and hermetic package are identical across both variants. The distinction lies solely in the guaranteed maximum operating frequency — the -1 suffix denotes a higher tested speed grade at 763 MHz internal performance, while the standard grade AX1000-CQ352M suits designs operating at lower system clock rates. Both devices share the same PCB footprint, making speed grade selection a straightforward design decision with no layout impact.

Frequently Asked Questions (FAQ)

What Is the ACTEL AX1000-CQ352M and What Does It Do?

The ACTEL AX1000-CQ352M is an Axcelerator family antifuse FPGA delivering 612,000 equivalent system gates at standard speed grade, with 165 Kbits of embedded SRAM, FuseLock security, and multi-standard I/O in a 352-pin ceramic CQFP hermetic package, rated for military M-grade operation from –55°C to +125°C.

How Does the ACTEL AX1000-CQ352M Differ From the AX1000-1CQ352M?

The ACTEL AX1000-CQ352M and AX1000-1CQ352M share identical gate density, SRAM, I/O standards, package, and military temperature rating. The sole difference is the speed grade — the -1 variant guarantees higher maximum internal performance at 763 MHz, while the standard grade AX1000-CQ352M is the cost-effective choice for designs operating at lower system clock frequencies.

Is the ACTEL AX1000-CQ352M SEU Immune?

Yes. The antifuse architecture of the ACTEL AX1000-CQ352M is inherently immune to single-event upsets (SEU) and firm errors caused by high-energy particle strikes, making it a trusted choice for space, avionics, and radiation-exposed military environments where SRAM-based FPGAs are vulnerable to configuration corruption.

What Is the Operating Temperature Range of the ACTEL AX1000-CQ352M?

The ACTEL AX1000-CQ352M is rated for military M-grade operation from –55°C to +125°C, suitable for the full range of airborne, shipboard, and ground-based military platform environments.
