A54SX16A-1TQ100M

The A54SX16A-1TQ100M is a member of the SX-A family of nonvolatile, single‑chip FPGAs from Microchip Technology. It provides 24,000 system gates across 1,452 logic elements with up to 81 user I/Os in a surface‑mount 100‑pin package, targeted at applications that require reprogrammable logic with integrated configuration and hardware security.

Designed for robust operation, this military‑grade device supports a wide supply range (2.25 V to 5.25 V) and an operating temperature range of −55 °C to 125 °C, making it suitable for designs that demand wide temperature tolerance and mixed‑voltage I/O flexibility.

Key Features

• Core Capacity — 24,000 system gates implemented across 1,452 logic elements, providing mid‑range programmable logic for glue‑logic, protocol handling, and control functions.
• I/O and Interface Flexibility — 81 user I/Os with configurable support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports mixed‑voltage operation with 5 V input tolerance and 5 V drive strength.
• Performance — SX‑A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family specification).
• Configuration and Security — Nonvolatile, single‑chip configuration with Actel Secure Programming Technology (FuseLock™) to protect bitstreams and prevent reverse engineering (family feature).
• System and Testability — Boundary‑scan testing compliant with IEEE 1149.1 (JTAG) and in‑system diagnostic capability with Silicon Explorer II (family feature), enabling easier board‑level test and validation.
• Power and Reliability — Hot‑swap compliant I/Os and power‑up/power‑down friendly behavior (no sequencing required for supply voltages), simplifying system power sequencing.
• Package and Mounting — Surface‑mount 100‑LQFP package case; supplier device package listed as 100‑TQFP (14×14 mm).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Mixed‑Voltage Interface Modules — Use the configurable I/Os and 5 V tolerance to bridge or adapt signals between 2.5 V, 3.3 V and 5 V domains.
• PCI‑Based Embedded Systems — Deploy where 66 MHz PCI compliance and programmable logic are required for interface logic, protocol adaptation, or peripheral glue logic.
• Military and Rugged Electronics — Leverage the military grade designation and −55 °C to 125 °C operating range for designs requiring wide temperature operation.
• Secure In‑System Programmable Designs — Apply the device where nonvolatile configuration and FuseLock™ security are needed to protect intellectual property and enable field updates.

Unique Advantages

• Integrated Nonvolatile Configuration: Single‑chip FPGA architecture removes the need for external configuration memory, simplifying board design and lowering component count.
• Flexible Mixed‑Voltage I/O: Configurable I/O support across common voltage standards and 5 V input tolerance make the device adaptable to diverse system interfaces.
• Robust Temperature Performance: Military grade and a −55 °C to 125 °C operating range support demanding environmental requirements and extended‑life deployments.
• Deterministic Timing and Resource Control: Family features include deterministic, user‑controllable timing and support for 100% resource utilization and pin locking, aiding predictable system behavior.
• Security and Testability: Built‑in secure programming (FuseLock™) and IEEE 1149.1 boundary‑scan support simplify IP protection and board‑level test flows.
• Broad Supply Range: Operates from 2.25 V to 5.25 V, allowing flexible power architectures and compatibility with a range of system rails.
