A54SX32A-CQ256

The A54SX32A-CQ256 is a commercial-grade SX‑A family FPGA from Microchip Technology, delivered in a 256‑pin BFCQFP package with tie bar. It provides 48,000 system gates implemented as approximately 2,880 logic elements, with 203 user I/Os for board‑level interfacing and glue logic.

Designed for commercial embedded designs, the device supports a wide supply range (2.25 V to 5.25 V), surface‑mount packaging, and RoHS compliance—making it suitable for mixed‑voltage I/O applications and standard commercial temperature environments (0 °C to 70 °C).

Key Features

• Core Logic — Approximately 48,000 system gates implemented as 2,880 logic elements, enabling mid‑density programmable logic on a single chip.
• Flip‑Flop Resources — Dedicated flip‑flop resources are provided (1,080 maximum per family table entry), supporting register‑based designs and state machines.
• I/O and Voltage — 203 user‑programmable I/O pins with a wide device supply range of 2.25 V to 5.25 V for mixed‑voltage interfacing on a single FPGA.
• Package & Mounting — Supplied in a 256‑BFCQFP package with tie bar (supplier package: 256‑CQFP, 75 × 75), optimized for surface‑mount PCB assembly.
• Temperature & Grade — Commercial grade operation with an ambient temperature range of 0 °C to 70 °C.
• Compliance & Environmental — RoHS‑compliant manufacturing status for regulatory and environmental requirements.
• Family‑Level Capabilities (SX‑A series) — The SX‑A family datasheet documents features such as Actel Secure Programming Technology with FuseLock, boundary‑scan (IEEE 1149.1 JTAG) support, and configurable I/O options for PCI and LVTTL/TTL signaling.

Typical Applications

• PCI and legacy interface logic — Use the SX‑A family’s configurable I/O and documented PCI support to implement board‑level PCI glue logic and interface translation.
• Mixed‑voltage board glue — The wide supply range (2.25 V–5.25 V) and extensive I/O count allow integration of multiple voltage domains and signal standards on a single FPGA.
• Secure, programmable control — Family features such as FuseLock secure programming make the device suitable for designs requiring on‑chip configuration protection.
• Boundary‑scan test environments — IEEE 1149.1 (JTAG) boundary‑scan support simplifies manufacturing test and in‑system diagnostics.

Unique Advantages

• Mid‑density integration: 48,000 system gates and 2,880 logic elements consolidate logic functions that would otherwise require multiple discrete devices.
• Flexible I/O and power: 203 I/Os with a broad 2.25 V–5.25 V supply span enable mixed‑voltage interfacing without external level translators in many cases.
• Commercial temperature ready: Rated for 0 °C to 70 °C operation to match mainstream commercial product requirements.
• Surface‑mount, high‑pin packaging: 256‑pin BFCQFP with tie bar provides high I/O density in a board‑mountable form factor suitable for complex PCB layouts.
• Regulatory and environmental compliance: RoHS compliance supports environmental requirements for commercial products.
