A54SX32-1TQG144 概要
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks and interconnects that can be configured in the field to implement custom digital circuits. Within the programmable logic hierarchy, the device sits as a one-time-programmable (OTP) fabric under the broader category of programmable logic devices, positioned by Microchip alongside its ProASIC and RTAX families. The SX family uses a sea-of-modules architecture combining C-cells (combinational logic) and R-cells (sequential logic) to deliver ASIC-like performance and integration levels not achieved by SRAM FPGAs of its generation.
Key features include the antifuse interconnect technology, which provides non-volatile, secure, radiation-tolerant-friendly configuration with no external boot PROM; 3.3V core operation with 5V-tolerant I/O; and deterministic sub-nanosecond interconnect delays that simplify timing closure. The 280 MHz maximum toggle capability supports performance-intensive applications such as high-speed bus interfacing and protocol bridging.
The sea-of-modules architecture eliminates the hierarchical routing delays typical of SRAM FPGAs, enabling predictable, short gate-to-gate delays. Because configuration is stored in antifuse elements, the device draws no configuration current at power-up and offers high resistance to design cloning compared with reprogrammable alternatives.
Typical applications include industrial control systems, medical equipment, communications and networking line cards, and military/aerospace embedded control where high gate density, instant-on operation, and design security matter. Supply-chain listings also associate the A54SX32 family with industrial and medical equipment designs.
Design consideration: as an OTP antifuse device, prototype iterations require new devices for each design change; plan logic verification thoroughly in simulation before programming. The commercial temperature grade (no I suffix) is specified for 0C to +70C operation.

主な用途
A54SX32-1TQG144 の用途: 6 件s: Industrial Control Systems, Medical Equipment, Communications and Networking Line Cards, Aerospace and Defense Embedded Control, High-Speed Bus Interface and Glue Logic, Design-Secure Embedded Systems.
Industrial Control Systems
The A54SX32-1TQG144 fits industrial control applications because its 5V-tolerant I/O (113 user I/O on 3.3V core logic) connects directly to legacy PLC sensor and actuator interfaces without level-shifting, and its antifuse fabric is instant-on at power-up, eliminating configuration-boot latency that matters in safety interlock chains. In a typical control board, the FPGA sits between a microcontroller and high-channel-count I/O, implementing glue logic, encoders, PWM generators, and parallel bus bridges. The deterministic sea-of-modules routing gives stable, predictable propagation delays for closed-loop timing. The trade-off versus reprogrammable FPGAs is fixed functionality after programming, acceptable in released production designs. Microchip lists the A54SX32 family explicitly for industrial equipment integration.
おすすめ
Medical Equipment
Distributor data explicitly associates the A54SX32-1TQG144 with medical equipment designs. Its suitability comes from instant-on antifuse configuration (no bitstream load window in which a monitoring subsystem could miss data), 113 user I/O for dense sensor-array front ends, and the design security of one-time-programmable interconnect, which protects proprietary measurement algorithms embodied in the fabric. Typical roles include patient-interface board glue logic, parallel data acquisition aggregation feeding an ADC such as the ADS1220IPWR, and control timing for pump or valve drivers. The 280 MHz-class fabric timing headroom keeps multi-channel acquisition loops deterministic. For new medical designs, evaluate the SX-A or ProASIC families for reprogrammability during regulatory iteration cycles.
おすすめ
Communications and Networking Line Cards
The 280 MHz maximum clock capability of the -1 speed grade A54SX32 makes it effective in telecommunications line-card roles such as protocol bridging, backplane bus interfacing, and framing logic. The SX architecture was specifically positioned by Actel/Microchip for performance-intensive applications where SRAM FPGA routing delays would limit throughput: the sea-of-modules fabric yields short, predictable gate-to-gate delays that simplify meeting backplane setup-and-hold budgets. In a typical design the FPGA terminates a parallel backplane and forwards packet data to PHY devices over 5V-tolerant legacy buses or LVTTL interfaces. The 32,000-gate capacity suits framing, multiplexing, and status logic rather than heavy DSP. Instant-on operation also supports hot-redundancy line cards that must be active immediately.
おすすめ
Aerospace and Defense Embedded Control
The antifuse technology in the A54SX32-1TQG144 underpins its use in military and aerospace embedded control: configuration is immune to configuration-memory upset, the die carries no SRAM configuration to latch up, and OTP interconnect provides inherent resistance to design extraction. Distributor listings (Jotrin, Microchip USA) emphasize the CMOS SX architecture's reliability profile and 5V-tolerant I/O for interfacing legacy military-standard bus logic. Typical applications include sensor conditioning, redundant-lane voting logic, and telemetry framing feeding downstream communication devices. Designers needing radiation-tolerant qualification should migrate to Microchip's RTAX-S family, for which XAIPART stocks numerous RTAX2000S and RTAX250S variants; the commercial SX part serves non-rad programs and ground equipment where OTP security and instant-on remain the deciding factors.
おすすめ
High-Speed Bus Interface and Glue Logic
As a general high-speed interface device, the A54SX32-1TQG144 consolidates discrete glue logic, bus transceivers, and address decoding into a single 32,000-gate, instant-on device. The 0.35 um CMOS fabric with 5V-tolerant I/Os lets one TQFP-144 package bridge 5V TTL peripheral buses to a 3.3V processor subsystem, replacing dozens of 74-series devices and shrinking board area while cutting cost and power. The deterministic routing delays of the sea-of-modules architecture make timing closure for address-decode and bus-handshake logic straightforward with static timing analysis. Because the device programs once, use it in designs past the prototype stage; keep a socketed or reprogrammable companion device such as a ProASIC/flash family part for frequently changing interface prototypes on the same board.
おすすめ
Design-Secure Embedded Systems
Where intellectual-property protection drives component choice, the A54SX32-1TQG144 offers a structural security advantage: antifuse interconnects physically form (or not) at programming, leaving no readable configuration bitstream, unlike SRAM FPGAs whose bitstream can be intercepted at boot. This makes the device suitable for proprietary authentication engines, copy-protection logic, and secure key-handling front ends in commercial products. The 32K gates accommodate AES-class and ECC-class logic cores of the era, while 113 user I/O integrate the secure block with the rest of the system. Instant-on operation also removes the boot-time attack window present in SRAM architectures. The trade-off is immutability: any security patch requires replacing the device, so couple it with field-updatable system firmware for mitigation logic.

設計ノート
The SX family requires multiple supply rails: 3.3V core/I/O plus programming supplies (VPP/VCI) defined in the datasheet pinout. Decouple each VCC/GND pair with 0.1 uF ceramic capacitors placed within 2 mm of the pin, and add 10 uF bulk capacitance per rail. Because antifuse programming occurs at the programming house, ensure programming-supply pins are wired per the Microchip programming specification even though they are inactive in normal operation. Estimated: with 32K gates of static CMOS logic at commercial toggle rates, typical core current remains in the tens-of-mA range, but verify against the -1 speed grade power calculator in Microchip Libero for your utilization.
This is a one-time-programmable antifuse FPGA: there is no field reconfiguration. Every logic change after programming requires a new device, so complete the full simulation and static-timing sign-off in Microchip Libero/Designer before submitting the design file for programming. Also note the temperature grade embedded in the ordering code: A54SX32-1TQG144 (no I suffix) is the commercial grade; for extended-temperature environments order the A54SX32-1TQG144I. Mixing grades on one board creates unmarked reliability risk since the packages are visually identical.
The 144-pin TQFP (0.5 mm lead pitch, 1.4 mm package height) requires fine-pitch land patterns per the Microchip package drawing; use a no-clean flux process or clean thoroughly under the package, as the 1.4 mm standoff limits inspection access. Assign the 113 user I/Os in Libero respecting I/O bank voltage domains so 5V-tolerant and 3.3V signal groups land on compatible banks. Route unused I/O as per datasheet recommendation (typically tied or configured as inputs with pull options) rather than leaving them floating to avoid increased power and noise susceptibility.
コンプライアンス情報
