A3P250L-VQ100I 概要
An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device that implements digital logic through configurable logic blocks, routing fabric, and I/O cells. Within the programmable logic hierarchy, the ProASIC3L family sits in the low-density, low-power class of flash-based FPGAs, distinct from SRAM-based FPGAs because configuration is stored in on-chip flash cells rather than external boot memory.
Key features include nonvolatile flash programming (single-chip solution, no external configuration PROM), Flash*Freeze technology that cuts static power dramatically while retaining SRAM state and instant wake-up, and secure FPGA bitstream storage. The L suffix denotes the low-power 1.2V-core variant of the ProASIC3 architecture on a 130nm flash process, reducing static and dynamic power versus the standard A3P250.
The ProASIC3L fabric combines VersaTiles (fine-grained logic tiles), embedded 4,608-bit Block RAM modules, and I/O banks supporting multiple voltage standards. Timing closure is simplified by a deterministic flash-based routing architecture, and the fabric supports clocks into the hundreds of megahertz range per family characterization.
Typical applications include industrial control and automation, portable and battery-powered instruments, secure embedded controllers, bridge logic and glue logic consolidation, and space- or power-constrained systems where instant-on operation and configuration security matter.
A key design consideration is I/O banking: assign I/O standards per bank to avoid voltage conflicts, and budget the 1.2V core rail and auxiliary 2.5V/3.3V supplies separately. Flash*Freeze mode requires attention to I/O state retention rules in the datasheet.

主な用途
A3P250L-VQ100I の用途: 6 件s: Industrial Control and Automation, Battery-Powered Portable Instruments, Secure Embedded Controllers, Bridge Logic and Glue Logic Consolidation, Aerospace-Adjacent Power-Constrained Data Paths, IoT Edge Sensor Aggregation.
Industrial Control and Automation
The A3P250L-VQ100I fits industrial controllers because it combines instant-on nonvolatile flash configuration with 68 user I/O, letting a single chip replace glue logic, I/O expansion, and sequencing circuits on a PLC or motor-control board. Its industrial -40C to +100C junction rating matches factory-floor ambient extremes, and the 1.14V to 1.575V core rail integrates cleanly with standard 1.2V/3.3V supply trees. In a typical control board, the FPGA sits between a microcontroller and field I/O, handling PWM generation, quadrature decoding, and safety interlock logic in the fabric for deterministic microsecond-level response that software loops cannot match. Because the bitstream is stored on-chip, boards power up functional in milliseconds with no external configuration device to fail or be corrupted in electrically noisy environments.
おすすめ
Battery-Powered Portable Instruments
Battery-operated field instruments benefit directly from the L variant's 1.2V core and Flash*Freeze technology, which drops static power drastically while retaining SRAM state and waking within microseconds on an external trigger. The A3P250L-VQ100I can hold sensor-acquisition logic in active mode only during measurement bursts, then enter Flash*Freeze between readings, extending battery life versus always-on SRAM FPGAs that burn static current continuously. Its single-chip flash architecture also removes the boot current and board area of a configuration SPI flash. With 68 I/O, the device can interface displays, keypads, and multiple sensor buses (SPI, I2C-style interfaces implemented in fabric). The 100-TQFP's 0.5mm pitch keeps assembly on standard SMT lines, and the industrial temperature rating covers outdoor handheld use.
おすすめ
Secure Embedded Controllers
Flash-based ProASIC3L devices store configuration in nonvolatile on-chip flash cells, which are inherently harder to read back than SRAM configuration bitstreams, making the A3P250L-VQ100I attractive for secure embedded controllers in access-control, metering, and cryptographic front-end roles. The fabric implements encryption blocks, key storage logic, and board-level tamper-response sequencing, while 36,864 RAM bits hold working keys and session state. The single-chip design eliminates the external configuration flash that is a common read-out attack surface in SRAM FPGA systems. Designers should still apply Microchip's security application notes for flash FPGA design protection features, and combine the fabric security with proper power-glitch and clock-glitch countermeasures at the board level for defense-in-depth.
おすすめ
Bridge Logic and Glue Logic Consolidation
The A3P250L-VQ100I excels at consolidating discrete glue logic - bus bridges, level-tolerant interface translation, wait-state generators, and legacy ASIC emulation - into one reprogrammable 100-TQFP device. Its 250K gates comfortably absorb dozens of 74-series functions, and the fine-grained VersaTile fabric maps small random logic efficiently. Because the design can be updated in-system over JTAG through the flash programming interface, ECOs and interface changes do not require board respins, cutting revision cost dramatically versus fixed-function ASSPs. The 68 user I/O with multiple banking voltage standards lets one chip bridge a 3.3V microprocessor bus to 2.5V or lower-voltage peripheral banks. Designers should group I/O standards per bank in Libero to respect bank voltage rules and avoid contention during power-up.
おすすめ
Aerospace-Adjacent Power-Constrained Data Paths
While the commercial I-grade A3P250L-VQ100I is not a flight-qualified part, its ProASIC3L architecture is the same fabric family used in high-reliability programs, and the flash cell is inherently tolerant of configuration upsets that plague SRAM FPGAs under radiation. Engineers prototyping low-power sensor front ends, telemetry formatters, and reconfigurable data path blocks benefit from the deterministic flash routing and 1.2V core power profile. The 36,864-bit Block RAM supports FIFOs and line buffers for serial telemetry streams, and fabric-implemented UARTs, SPI, and custom serial protocols adapt as mission requirements evolve. For flight use, migrate to the appropriate qualified orderable within the Microchip space portfolio; the VQ100 prototype footprint can be carried into board families using the same fabric HDL.
おすすめ
IoT Edge Sensor Aggregation
In IoT edge nodes, the A3P250L-VQ100I aggregates multiple sensor interfaces into one programmable fabric block that preprocesses data before handing it to a low-power MCU or radio. Its low static power and Flash*Freeze mode suit duty-cycled nodes that wake on event triggers, sample sensors through fabric-implemented SPI/I2C-style masters, apply thresholding or filtering in the 250K-gate fabric, and return to sleep. The nonvolatile configuration means field-deployed nodes resume operation immediately after brownouts or battery swaps without reprogramming, an important availability feature for unattended deployments. The industrial temperature range and standard 0.5mm-pitch TQFP assembly simplify deployment in outdoor enclosures. Designers must budget the 1.14V to 1.575V core rail from the node's buck converter with adequate decoupling.

設計ノート
Supply the A3P250L-VQ100I core from a regulated 1.2V rail (allowed range 1.14V to 1.575V) with at least 10uF bulk plus 0.1uF/0.01uF ceramic decoupling at each VCC pin pair, per Microsemi power-guidance for ProASIC3L. I/O banks require their own clean VCCI rails matching the chosen I/O standards. Estimated: static core current in Flash*Freeze is orders of magnitude below active mode, so a small LDO suffices for sleep but size the DC-DC for active toggle-dependent dynamic current per Libero SmartPower estimates.
The 100-TQFP with 0.5mm lead pitch requires careful fanout: use 0.2mm via-in-free-pad or dog-bone escapes on outer rows, and keep the center paddle-free footprint per the Microsemi package drawing. Place JTAG header, programming resistors, and the 1.2V/2.5V test points on the first revision to enable in-system flash programming. Route I/O banks so that all pins sharing a bank use the same VCCI standard - mixing standards in one bank is the most common PCB respin cause on VQFP FPGAs.
Do not treat the L part like the standard A3P250: core rails differ and swapping the A3P250-VQ100I onto an L-designed board over-voltages the core. Verify Flash*Freeze entry/exit handshake timing in simulation - I/O states are retained but wake-up latency and pin behavior during transition must follow the ProASIC3L datasheet. Finally, confirm speed-grade ordering codes (base vs -1/-2) before release; timing reports from Libero are only valid for the ordered grade.
コンプライアンス情報
RoHS/lead-free status not stated in the verified web data for this exact ordering code. Confirm on the Microchip product page certificate of conformance; VQG-suffix parts are typically green/lead-free packages.
