A54SX32-2TQG144I

The A54SX32-2TQG144I is a nonvolatile SX-family Field Programmable Gate Array (FPGA) offered by Microchip Technology. Built on the SX-A series architecture, this device provides a mix of logic density, I/O flexibility and single-chip nonvolatile configuration for embedded and industrial designs.

With 48,000 gates, approximately 2,880 logic elements and 113 user I/Os in a 144-pin thin quad flat pack, the device targets control, interface and mixed-voltage applications that require industrial temperature operation and broad supply-voltage tolerance.

Key Features

• Core Capacity — 48,000 system gates and approximately 2,880 logic elements provide mid-range logic integration for glue logic, state machines and custom accelerators.
• I/O Flexibility — 113 user-programmable I/Os with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 signaling as documented for the SX-A family.
• Mixed-Voltage Operation — Supports 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength per the SX-A feature set; device supply range is 3 V to 5.5 V.
• Performance — Series-level performance figures include up to 250 MHz system performance and up to 350 MHz internal performance (SX-A family values).
• Nonvolatile Single-Chip Configuration — SX-A family offers a nonvolatile, single-chip solution that eliminates the need for external configuration memory.
• Industrial Grade Temperature — Rated for industrial operation from −40 °C to +85 °C to meet embedded system environmental requirements.
• Package — 144-pin thin quad flat pack (TQFP/LQFP style) with supplier package listed as 144-TQFP (20×20 mm) for compact board-level integration.
• System and Test Features — Family features include boundary-scan testing (IEEE 1149.1/JTAG) and in-system diagnostic capabilities such as Silicon Explorer II.
• Security and Reliability — Actel Secure Programming technology with FuseLock is documented for the SX-A family to protect configuration and prevent reverse engineering.
• Power-Up/Down Friendly I/Os — Hot-swap compliant I/Os and no required sequencing for supply voltages, consistent with SX-A family specifications.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial control and automation — Implement motor control logic, protocol adaptation and deterministic I/O handling in industrial systems that require industrial temperature range and mixed-voltage interfacing.
• Legacy and mixed-voltage interfaces — Bridge between 5 V TTL and modern 3.3 V/2.5 V domains or implement PCI-compatible interfaces, leveraging the SX-A family’s configurable I/O options and 66 MHz PCI compliance.
• Embedded system glue logic — Replace complex discrete logic networks with a single-chip programmable solution to consolidate state machines, bus arbitration and custom peripherals.
• In-system diagnostics and verification — Use the device’s in-system diagnostic capabilities for field debugging, verification and iterative development workflows.

Unique Advantages

• Nonvolatile single-chip solution: Eliminates external configuration memory and simplifies system BOM and startup sequencing.
• Mixed-voltage I/O support: Flexible I/O standards and 5 V tolerance reduce the need for level translators and enable seamless integration with legacy peripherals.
• Industrial temperature rating: −40 °C to +85 °C specification supports deployment in demanding embedded and industrial environments.
• Compact, high-pin-count package: 144-pin TQFP/LQFP enables dense I/O and logic in space-constrained board designs.
• Design security: FuseLock secure programming technology helps protect intellectual property and prevent reverse engineering.
• Testability and diagnostics: Boundary-scan (JTAG) and Silicon Explorer II capabilities streamline manufacturing test and in-field diagnostics.
