A54SX16P-2TQG176

The A54SX16P-2TQG176 is a nonvolatile SX-family FPGA from Microchip Technology, offered in a 176‑pin thin quad flat package for surface-mount applications. It delivers a compact programmable-logic solution with 24,000 system gates and 1,452 logic elements suited for control, interface and I/O‑intensive designs.

With 147 user I/Os, configurable mixed‑voltage support and a commercial temperature rating, this device targets embedded systems and interface applications that require in-system programmability, I/O flexibility and deterministic timing behavior.

Key Features

• Core & Capacity 24,000 system gates and 1,452 logic elements provide a mid-range logic fabric for glue logic, protocol handling and custom control functions.
• I/O and Mixed‑Voltage Support 147 user I/Os with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2. Devices support mixed‑voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance & Speed Grade Family-level performance up to 250 MHz system and 350 MHz internal operation; this part uses the –2 speed grade (approximately 25% faster than standard).
• Nonvolatile Single‑Chip Solution On-chip nonvolatile configuration removes the need for external configuration memory, simplifying board design and start-up behavior.
• Power & I/O Behavior Hot‑swap compliant I/Os and power‑up/power‑down friendly operation require no special sequencing for supply voltages; rated supply range is 3 V to 5.25 V.
• Security & Test Built‑in security through Actel Secure Programming Technology (FuseLock™) and boundary‑scan testing compliant with IEEE 1149.1 (JTAG) for manufacturing and field diagnostics.
• Package & Environmental 176‑pin thin LQFP (supplier package 176‑TQFP, 24×24) in a surface‑mount form factor; commercial temperature grade 0 °C to 70 °C and RoHS compliant.

Typical Applications

• Interface Bridging and Level Translation Mixed‑voltage I/O capability and 147 I/Os make this FPGA suitable for bridging between 5 V and lower‑voltage subsystems or consolidating multiple interface functions.
• Legacy PCI and System I/O 66 MHz PCI compliance and configurable 3.3 V/5 V PCI I/O support enable integration with legacy PCI endpoints and add programmable logic to existing system buses.
• Embedded Control and Glue Logic Mid‑range gate count and deterministic timing are useful for control engines, protocol offload, and board‑level logic consolidation in commercial products.
• Production Test and Diagnostics Boundary‑scan (IEEE 1149.1) and in‑system diagnostic capabilities facilitate board test, manufacturing validation and field troubleshooting.

Unique Advantages

• Highly configurable I/O: Flexible support for multiple voltage standards and 5 V tolerance reduces the need for external level translators and simplifies mixed‑voltage designs.
• Nonvolatile configuration: Single‑chip nonvolatile FPGA removes external configuration flash or EEPROM, reducing BOM and board complexity.
• Deterministic, user‑controllable timing: Predictable timing behavior helps designers meet timing requirements for synchronous interfaces and control logic.
• On‑board security features: FuseLock™ secure programming protects design IP and prevents unauthorized readback or reverse engineering.
• Manufacturing and field test support: IEEE 1149.1 boundary‑scan and in‑system diagnostic capabilities speed up bring‑up and improve serviceability.
• RoHS compliant commercial module: Surface‑mount 176‑LQFP package in a commercial temperature range enables straightforward integration into consumer and industrial equipment with standard assembly processes.
