A54SX32-2TQ144

The A54SX32-2TQ144 is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It provides a hardware-configurable logic solution with 48,000 system gates and approximately 2,880 logic elements, designed for applications that require mixed-voltage I/O flexibility and predictable timing.

This device targets commercial-temperature designs that need up to 113 user I/Os in a 144-pin thin quad flat pack (TQFP/LQFP) package and supports a wide supply range of 3 V to 5.25 V.

Key Features

• Core Performance — Family-level performance specifications include up to 250 MHz system performance and up to 350 MHz internal performance, with the –2 speed grade indicating approximately 25% faster performance than the standard grade.
• Logic Capacity — 48,000 system gates with approximately 2,880 logic elements and dedicated flip-flops for implementing combinational and sequential logic.
• I/O and Interface Flexibility — Up to 113 user-programmable I/Os in the 144-pin package; configurable I/O support for multiple standards including 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 (family-level feature).
• 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 (family-level feature).
• Nonvolatile Single-Chip Architecture — On-chip nonvolatile configuration removes the need for separate configuration memory (family-level feature).
• Package & Mounting — 144-LQFP (thin quad flat pack) surface-mount package (20 × 20 mm TQFP footprint noted) for compact board-level integration.
• Power and Supply — Operates from a wide supply range of 3 V to 5.25 V and is power-up/power-down friendly with no sequencing required for supply voltages (family-level feature).
• System Reliability & Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability with Silicon Explorer II (family-level features).
• Security — Actel Secure Programming Technology with FuseLock™ prevents reverse engineering and design theft (family-level feature).
• Compliance & Environmental — RoHS compliant.
• Operating Range — Commercial temperature grade rated from 0 °C to 70 °C.

Typical Applications

• Mixed-Voltage Interface Control — Use where designs require configurable I/O standards and 5 V input tolerance to bridge different logic domains.
• Embedded Logic Integration — Implement application-specific control, glue logic, or protocol handling using the device’s 48,000 system gates and ~2,880 logic elements.
• Compact Board-Level Solutions — Deploy in space-constrained commercial products that benefit from a 144-pin TQFP surface-mount package and single-chip nonvolatile configuration.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates external configuration memory and simplifies BOM and board design.
• Mixed-voltage I/O with 5 V tolerance: Enables direct interfacing with legacy 5 V logic while supporting lower-voltage domains.
• Deterministic timing and high internal performance: Family-level timing characteristics and the –2 speed grade provide improved performance margin for timing-critical logic.
• Built-in security and test support: FuseLock programming and IEEE 1149.1 boundary-scan support help protect IP and simplify production test.
• Power-up/down friendly operation: No supply sequencing required, reducing system-level power management complexity.
• RoHS compliant: Meets environmental requirements for lead-free assembly.
