A54SX16P-2TQG176I - 16K Gate SX FPGA 320MHz TQFP-176 | Microchip

The Microchip Technology (Microsemi) A54SX16P-2TQG176I is an SX-family Field Programmable Gate Array (FPGA) offering 16,000 system gates (24K system gates per Mouser categorization), 924 logic cells, and a maximum toggle rate of 320 MHz, housed in a 176-pin TQFP (TQG176) surface-mount package with 147 user I/O pins. It operates from a 3.0V to 3.6V supply (3.3V nominal, 5V-tolerant I/O) and is rated for the industrial temperature range denoted by the I suffix. An FPGA is a reconfigurable semiconductor device whose logic function is defined at design time rather than fixed at fabrication. Within the digital logic hierarchy, the FPGA sits above fixed-function ASICs and ASSPs: it belongs to the programmable logic family, alongside CPLDs and programmable SoCs, and is a core building block of embedded system and power management architectures. Key features of the A54SX16P include the SX sea-of-modules architecture, which simplifies timing-driven design, reduces design cost and power consumption, and shortens time to market for performance-intensive applications. The device provides 1452 LABs/CLBs of configurable logic, 0.35 um CMOS process technology, and speed grade -2, balancing performance and cost. The P-suffix variant supports antifuse-based one-time programmability, delivering design security and radiation-tolerant behavior valued in industrial and aerospace-derived systems. Technically, the SX family uses a sea-of-modules structure with dedicated registers and carry logic for arithmetic, achieving predictable interconnect delays. The 320 MHz maximum clock frequency and 147 programmable I/O make it suitable for glue logic consolidation, bus interfacing, protocol bridging, and control state machines in embedded systems. Industrial-grade (I) temperature rating supports extended-environment deployments. Typical applications include industrial automation control, communications and networking interface bridging, and military/aerospace-derived or high-reliability industrial systems where one-time-programmable antifuse security matters. A key design consideration: antifuse FPGAs are one-time programmable, so designers must fully validate the bitstream before programming production units, and Libero SoC design software from Microchip is required for synthesis and place-and-route.

The Microsemi (Actel, now Microchip Technology) A54SX16P-2VQG100I is a 16,000-gate antifuse field-programmable gate array (FPGA) from the SX family, with 924 logic modules, up to 81 user I/O, a -2 speed grade supporting system clock rates up to 320 MHz, packaged in a 100-pin VQFP/TQFP surface-mount enclosure and rated for the industrial temperature range (-40C to +85C). An antifuse FPGA is a type of one-time-programmable (OTP) field-programmable gate array in which programmable interconnect elements are formed by amorphous silicon antifuse links. Unlike SRAM-based FPGAs, an antifuse device retains its configuration permanently with no external boot flash, no configuration time at power-up, and inherent resistance to readout - making the family a hierarchy ancestor of modern one-time-programmable, security-focused programmable logic within the broader power-management and logic-IC ecosystem. Key features include the 0.35 um CMOS sea-of-modules architecture, dual 3.3V/5V I/O compatibility for mixed-voltage board designs, and 1452 configurable logic building blocks organized for high routing efficiency. The SX family delivers ASIC-like gate utilization and deterministic timing that simplify design closure in performance-intensive applications. Technical depth: the SX sea-of-modules architecture replaces the channel routing of conventional FPGAs with a dense sea of C-cells (combinational) and S-cells (sequential), giving short, predictable interconnect delays. The -2 speed grade in the VQG100 package supports a 320 MHz maximum toggle/system clock rate, and the antifuse interconnect adds negligible parasitic capacitance compared with pass-transistor-based SRAM routing, which is the primary source of the family's speed advantage. Typical applications include glue-logic consolidation and ASIC prototype reduction in industrial control, high-speed bus bridging and interface translation in communications equipment, and secure, instant-on control logic in avionics-adjacent and defense-adjacent industrial systems where non-volatile, configuration-readout-resistant logic is preferred. Design consideration: because the device is one-time-programmable, verify the design exhaustively in simulation and - where possible - in a lower-cost equivalent package before committing programming; there is no field re-work path.

Key features of the A54SX16P include 320 MHz internal performance, 3.7 ns pin-to-pin clock-to-out, 0.1 ns input setup time, and 0.25 ns clock skew - specifications that enabled single-chip 66 MHz PCI integration. The P-suffix variant supports 3.3 V core operation with 5.0 V-tolerant inputs, simplifying mixed-voltage board designs. The sea-of-modules architecture achieves 100% resource utilization with 100% pin locking, reducing design iterations. Technically, the SX family uses a sea-of-modules architecture that simplifies timing closure and enables deterministic routing. The dual supply support (3V to 3.6V core and 4.75V to 5.25V I/O domains on P variants) bridges legacy 5V systems with 3.3V logic. The antifuse-based programming retains configuration through power cycles without an external configuration device. Typical applications include 66 MHz PCI bus interfaces, industrial control backplanes, telecommunications line cards, and legacy military/aerospace designs requiring 5V-tolerant I/O. The industrial temperature grade (I suffix, -40C to +85C TA) suits harsh environments. Design consideration: as this part is a mature/legacy device, verify current supply availability and consider design migration planning; the antifuse fabric is one-time-programmable, so plan in-system retest strategy accordingly.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic IC that allows designers to implement custom digital circuits after manufacturing. The SX family uses Actel's pioneering antifuse programmable interconnect, a one-time-programmable technology at the root of the FPGA taxonomy (FPGA -> programmable logic device -> digital IC). Antifuse devices retain their configuration permanently, are inherently resistant to configuration readback, and require no external configuration PROM, unlike SRAM-based FPGAs. Key features of the A54SX16P include Actel's sea-of-modules architecture with 1452 logic modules, dual-supply operation supporting 3.3V core/5V-tolerant I/O rails (3.0V-3.6V core, 4.75V-5.25V I/O), and deterministic pin-to-pin timing enabled by the segmented routing fabric. The device provides 924 logic cells and supports a maximum clock frequency of 240 MHz, making it suitable for performance-intensive glueless integration. The sea-of-modules architecture places C-cells (combinational) and R-cells (sequential) in a dense array with short, low-capacitance routing segments, giving the A54SX16P predictable delays and high gate utilization. This yields performance comparable to much larger SRAM FPGAs while consuming significantly less static power, since antifuse interconnect draws no static configuration current. Typical applications include industrial automation controllers, communication and networking interface logic, embedded system glue logic and bus bridging, aerospace/defense control logic (where nonvolatile one-time programming is valued), and test-and-measurement instrumentation. The 175 I/O count and dual voltage support make it a strong fit for legacy 5V and 3.3V mixed-rail board designs. When designing with the A54SX16P, note that antifuse programming is one-time only: functional changes require a new device, so design freezes and thorough simulation in Libero/Microchip design tools are essential.

Key features include the sea-of-modules architecture with C-cells and S-cells for fast combinational and registered logic, deterministic pin-to-pin delays, and 100% FPGA design security because the programmed interconnect is invisible to readback. The antifuse technology eliminates configuration loading time and provides inherent resistance to configuration bitstream theft or corruption, a notable differentiator versus SRAM-based FPGAs from Xilinx and Intel (Altera). The 0.35 um process yields high reliability and low power consumption for its class, while the dual 3.3 V / 5 V I/O capability simplifies interfacing with legacy 5 V industrial and military logic systems. Maximum system frequency reaches 240 MHz on internal paths, supporting performance-intensive control and data-path functions. Typical applications include military and aerospace embedded control, industrial automation, bridge logic between mixed-voltage subsystems, communication protocol glue logic, and ASIC prototyping where one-time programmability is acceptable. A key design consideration: antifuse FPGAs are one-time programmable, so any design change requires a new device; budgets for rework should reflect this. Power supply design must accommodate both 3.3 V core-capable and 5 V tolerant interfacing scenarios as appropriate.

The Microsemi (Microchip Technology) A54SX16P-TQG144 is a 16,000-gate antifuse FPGA from the SX family, delivering 924 logic modules, 113 user I/O, and up to 240 MHz system performance in a 144-pin TQFP (20x20 mm, 0.5 mm pitch) surface-mount package. It operates from dual supply rails of 3.3V (3.0V to 3.6V) and 5V (4.75V to 5.25V) on a 0.35 um process. An antifuse FPGA is a field-programmable gate array whose interconnect elements are permanently programmed at power-up by an on-chip circuit that blows selected antifuse links. Unlike SRAM-based FPGAs from Xilinx or Altera, antifuse devices retain their configuration without any external boot memory, and their interconnect resistance and capacitance are lower, which historically gave the Actel SX family class-leading routing speed and security against design extraction. Key features include the sea-of-modules architecture with two module types (combinatorial C-modules and sequential S-modules), 16K system gates, and a guaranteed 240 MHz toggle-rate-class performance that suits state machines, glue logic integration, and high-speed control paths. The 113 available I/O in the TQFP-144 footprint provides generous pin-out flexibility for bus interfaces. Technically, the SX family uses a sea-of-modules fabric in which every module is surrounded by routing channels, simplifying place-and-route and shortening critical paths. The dual 3.3V/5V supply scheme allows direct interfacing with legacy 5V TTL systems while keeping core power low. Because configuration is stored in antifuse elements, startup is essentially immediate with no configuration download, improving system reliability and boot time versus SRAM FPGAs. Typical applications include industrial control and automation, bridge and interface logic in telecom and networking equipment, 5V legacy system integration, aerospace and defense control electronics, and medical instrumentation where one-time programmability and instant-on behavior are valued. When designing with this device, verify both supply rails meet the specified 3V to 3.6V and 4.75V to 5.25V windows, and confirm the commercial (0C to +70C, non-I suffix) temperature grade matches your environment; the -I suffix parts extend to industrial range.

Key features include a 240 MHz toggle rate enabled by the 0.35um process, 16K usable gates for mid-density glue logic, state machines and bus interfacing, and dual 3.3V/5V I/O compatibility for bridging legacy 5V systems with modern 3.3V logic. The antifuse fabric also offers low static power and zero configuration-load time at power-up, a distinct advantage over SRAM FPGAs. Technically, the device's sea-of-modules architecture provides predictable routing delays, beneficial for timing-critical designs. The 81 user I/O on the 100-pin VQFP give a 0.5 mm-pitch, 14x14 mm-class footprint suitable for compact industrial boards. Typical applications include industrial glue logic and bus bridging, military/avionics systems where OTP configuration integrity matters, telecommunications line cards, and legacy design sustainment for discontinued SRAM FPGA platforms. Design consideration: because the SX family is one-time programmable, verify the design thoroughly in simulation before programming; there is no in-system reconfiguration.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing a fabric of configurable logic blocks and interconnects that designers program after manufacturing. The SX family sits in the one-time-programmable (OTP) antifuse FPGA hierarchy, below the radiation-tolerant RTAX series and alongside the higher-density SX-A family, and is manufactured on a 0.35 um CMOS process. Antifuse FPGAs are favored where configuration volatility, instantaneous boot-up, and high resistance to radiation-induced configuration upsets matter more than in-field reprogrammability. Key features of the A54SX32-1BG329 include a sea-of-modules architecture that simplifies design capture and timing closure, dual supply operation of 3.3V core and 5V-tolerant I/O capability, and deterministic performance of up to 280 MHz in system-level benchmarks. The commercial-grade (no I suffix) operating range and 329-ball BGA with 1.27 mm ball pitch provide high I/O density for bus-intensive designs. Technical depth: the SX family uses the Actel combinational-logic module (CLM) fabric with a sea-of-modules routing structure, delivering gate utilization and performance close to masked gate arrays. Because programming is via metal-to-metal antifuse links, configuration data is fixed at power-up with no external boot ROM or configuration flash required, reducing BOM cost and improving security. Typical applications include industrial control, communications and networking line cards, test and measurement instrumentation, aerospace and defense sub-systems (where SX devices later spawned the RTAX rad-hard derivatives), and glueless bus-bridging logic requiring 249 I/Os. Design consideration: antifuse OTP devices cannot be reprogrammed, so thorough simulation and iteration on engineering samples are essential before committing programming current to production units.

A54SX32-1BGG329 - 32K-Gate FPGA, 280MHz, 329-BGA | Microchip

The Microchip Technology A54SX32-1BGG329 is a 32,000-gate CMOS field programmable gate array (FPGA) from the Actel SX family, delivering 2880 logic cells, up to 249 user I/O, and a maximum clock frequency of 280 MHz, housed in a 329-ball PBGA (BGG329) package with a 1.27 mm ball pitch. An FPGA is a semiconductor device containing a matrix of configurable logic blocks (CLBs) and programmable interconnects that designers configure in the field, after manufacturing, to implement custom digital logic. Within the programmable logic hierarchy - FPGA -> programmable logic device -> digital IC -> semiconductor - the SX family occupies the high-performance, one-time-programmable (OTP) antifuse segment, distinguished from SRAM FPGAs by its non-volatile, instantly-on configuration and inherent resistance to configuration corruption. Key features include the sea-of-modules architecture that yields deterministic, ASIC-like timing; 2880 configurable logic modules (CLBs) suitable for glue logic, bus bridging, and control-path functions; 249 user-input/output pins that support wide parallel buses; and operation at up to 280 MHz system clock, among the fastest of its generation. The antifuse interconnect technology eliminates configuration boot time, reduces power consumption versus SRAM-based parts, and improves design security because no configuration bitstream is stored externally. Technically, the SX family uses a 0.35 um-class CMOS process with a continuous grid of C-cells (combinational logic) and R-cells (sequential logic) connected through a segmented routing fabric. Unlike SRAM FPGAs, routing delays are predictable after place-and-route, simplifying timing closure for performance-intensive applications. The device supports mixed 3.3V/5V I/O operation per the SX family datasheet, easing interfacing with legacy TTL-level systems. Typical applications include industrial automation controllers, communications and networking line cards, avionics and military legacy-system sustainment, test and measurement equipment, and high-speed bus interface bridge logic where instant-on, high-reliability programmable logic is required. A key design consideration is that antifuse FPGAs are one-time programmable: the design must be fully verified before programming, since a functional change requires a new physical device.

An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks and interconnects that the designer programs after manufacturing. The SX family belongs to the one-time-programmable antifuse FPGA class, which sits within the broader programmable logic hierarchy: FPGA -> programmable logic IC -> programmable semiconductor. Unlike SRAM FPGAs, antifuse devices retain their configuration permanently, are inherently resistant to configuration readback, and require no external boot configuration memory. Key features include the sea-of-modules architecture that delivers high-performance, high-integration implementation with lower design cost and power consumption than SRAM-based alternatives, 1800 logic cells (2880 configurable logic modules), dual 3.3V/5V I/O compatibility, and the -1 speed grade supporting up to 280 MHz. The 329-ball BGA provides high I/O density for bus-intensive designs while remaining reworkable with standard BGA assembly processes. Technically, the SX family is fabricated on a 0.35 um CMOS process optimized for predictable timing. Because routing is fixed by the antifuse fabric, timing after programming closely matches pre-programming simulation, which simplifies sign-off in high-reliability systems. The device is programmed once using Microchip (formerly Actel/Microsemi) programmer hardware and design tools, then behaves as an ASIC-like fixed-logic device. Typical applications include industrial control and automation, communication and networking interface logic, glueless bus bridging, military/aerospace heritage systems requiring configuration security, and test equipment where deterministic timing is essential. Design consideration: antifuse FPGAs are one-time programmable - verify the design fully in simulation and timing analysis before programming, since a design change requires a new device.

The 174 user-I/O pins support both 3.3V and 5V signaling, easing mixed-voltage legacy system integration. Technically, the SX architecture separates dedicated clock resources and high-speed routing from the module fabric, enabling predictable, ASIC-like timing. Because antifuse programming is one-time, the device suits production designs where volatility, security against bitstream theft, and instant-on behavior matter more than in-field reconfigurability. Typical applications include industrial control, military and aerospace interfaces, communications line cards, test equipment, and glueless bridge logic between 5V legacy systems and 3.3V subsystems. The commercial temperature range (-part suffix 1C, 0C to +70C) targets cost-sensitive industrial and commercial deployments.

A54SX32-1PQG208 - 32K Gate SX FPGA, 208-PQFP | Microchip

The Microchip Technology (Microsemi/Actel) A54SX32-1PQG208 is an SX-family antifuse FPGA with 32,000 typical system gates, 1,800 logic modules, up to 280 MHz system performance, 174 user I/Os, and a 208-pin plastic quad flat pack (208-PQFP / 208-BFQFP) surface-mount package operating from a 3.3V/5V supply mix. An antifuse FPGA is a one-time-programmable (OTP) field-programmable gate array in which each programmable interconnect point is an open antifuse that is permanently shorted during programming. Unlike SRAM FPGAs, antifuse devices retain their configuration in silicon, require no configuration PROM, boot instantly at power-up, and are inherently resistant to configuration corruption - traits that placed the Actel SX family in a hierarchy running FPGA -> antifuse FPGA -> one-time-programmable programmable logic -> programmable semiconductor. Key features include the sea-of-modules architecture built from Combinatorial Modules (CMs) and Register Modules (RMs), which delivers gate utilization and routing efficiency well ahead of SRAM architectures of the same era; a 0.35 um CMOS process enabling internal toggle rates up to roughly 280 MHz; and a wide operating family spanning 6K to 60K system gates with I/O standards supporting 3.3V and 5V signaling. Technically, the SX architecture clusters CM/RM pairs into clusters and superclusters, keeping critical interconnect local and short. This is why the family achieves ASIC-like speed and deterministic timing without the configuration-load penalty of SRAM parts, while consuming low static power. Design entry uses the Actel/Microchip Libero design flow with VHDL or Verilog synthesis; programming is performed once via dedicated programming equipment because antifuses cannot be reprogrammed. Typical applications include glue logic and bus-interface consolidation in industrial control, aerospace and defense boards requiring instant-on, boot-free configuration, telecommunications line cards, and motor/automation controllers where design security matters. The PQFP-208 package suits reflow-soldered, moderately pin-dense boards. Design consideration: because the device is one-time-programmable, simulate thoroughly and freeze the design before committing silicon; a design change requires a new device, so plan procurement accordingly.
