A54SX16A-TQ100A

The A54SX16A-TQ100A is an SX-A family field programmable gate array (FPGA) from Microchip Technology, offered in a 100-pin TQFP/LQFP package. It provides a nonvolatile, single-chip FPGA solution with approximately 24,000 system gates and about 1,452 logic elements for mid-density logic integration.

Designed for applications that require configurable I/O and deterministic timing in a compact, qualified package, this automotive-grade device includes AEC-Q100 qualification and supports a wide supply range and extended operating temperature for deployment in demanding environments.

Key Features

• Core Logic — Approximately 24,000 system gates and about 1,452 logic elements provide mid-density FPGA capability for glue logic, control, and custom finite-state designs.
• I/O and Interface Flexibility — 81 user I/Os with configurable I/O support for 3.3V PCI, 3.3V LVTTL and 2.5V LVCMOS2. I/Os are hot-swap compliant and offer configurable weak pull-up or pull-down at power-up.
• Performance — SX-A family internal performance up to 250 MHz and 66 MHz PCI compliance support common embedded and bus-interface timing requirements.
• Nonvolatile Architecture — Single-chip, nonvolatile FPGA architecture removes the need for external configuration memory.
• Power and Sequencing — Power-up/down friendly behavior requires no sequencing for supply voltages, simplifying system power design.
• Timing and Output Control — Deterministic, user-controllable timing with individual output slew-rate control and support for up to 100% resource utilization and 100% pin locking.
• Security and Test — Secure programming with FuseLock™ to protect designs, plus boundary-scan testing compliant with IEEE 1149.1 (JTAG) for production testability.
• Package and Electrical — Available in a 100-pin TQFP/LQFP package (14×14 mm supplier footprint), operates from 2.25 V to 5.25 V and across –40 °C to 125 °C.
• Automotive Qualification & Compliance — Automotive grade with AEC-Q100 qualification and RoHS compliant.
• Family-Level Capabilities — SX-A family features include up to 2,012 dedicated flip-flops and family tools and diagnostics such as Silicon Explorer II (documented in SX-A family resources).

Typical Applications

• Automotive Control Systems — Automotive-grade qualification and extended temperature range support electronic control modules and in-vehicle logic functions.
• PCI and Bus Interface Logic — 66 MHz PCI compliance and configurable 3.3V PCI I/O support make the device suitable for bus interfacing and bridge functions.
• Embedded Control and Glue Logic — Mid-density logic capacity and deterministic timing are well suited for custom control functions, protocol translation, and signal conditioning.
• Sensor and Actuator Interfaces — Configurable I/O levels and hot-swap compliant pins enable robust interfacing to sensors, actuators and mixed-voltage peripherals.

Unique Advantages

• Automotive-qualified silicon: AEC-Q100 qualification and a –40 °C to 125 °C operating range support deployment in temperature-challenging environments.
• Nonvolatile, single-chip design: Eliminates external configuration memory and simplifies system BOM and startup behavior.
• Flexible I/O with hot-swap capability: Configurable I/O standards and hot-swap compliant pins reduce interface complexity for mixed-voltage systems.
• Deterministic timing and output control: User-controllable timing and individual slew-rate control help meet precise timing and signal-integrity needs.
• Built-in security and testability: FuseLock secure programming and IEEE 1149.1 boundary-scan support ease production test and protect IP.
• Compact package with substantial I/O: 81 I/Os in a 100-pin TQFP/LQFP footprint enable dense connectivity in space-constrained designs.
