A3P1000-1FGG256M 概要
A flash-based FPGA stores its configuration in on-chip flash cells rather than an external configuration PROM. This places the ProASIC3 family in the nonvolatile FPGA hierarchy, below SRAM FPGAs in reconfiguration flexibility but above them in system simplicity: the device powers up instantly as a single-chip solution with no boot device, no configuration bitstream on the board, and inherent resistance to configuration readback.
Key features include single-chip, reprogrammable flash fabric, a 1.5V core operating supply, support for 0C to +85C operation (commercial temperature grade per distributor data), and four I/O banks with independent bank voltages for mixed-voltage I/O standards. The VersaTile architecture lets each tile function as a three-input LUT or a D flip-flop/latch with enable, improving logic utilization at low densities.
Technically, ProASIC3 uses Microchip's third-generation flash FPGA fabric, achieving system-level performance suitable for glue logic consolidation, interface bridging, and control-plane designs where the low total cost of ownership (TOC) of a single-chip nonvolatile FPGA matters more than raw high-speed serial performance.
Typical applications include industrial automation control, power-on instant-on logic in aerospace and defense subsystems, communication interface bridging, and portable instrumentation where board space and configuration memory elimination are priorities.
Design consideration: the -1 speed grade is the slowest grade in the A3P1000 family; confirm timing closure for your design in Libero SoC before committing. The FGG256 package routes VCCIBx pins through their corresponding I/O banks, so mixed-standard assignments must respect bank boundaries.

主な用途
A3P1000-1FGG256M の用途: 6 件s: Industrial Automation and Control, Aerospace and Defense Subsystems, Communication Interface Bridging, Portable and Battery-Powered Instrumentation, Medical Diagnostic Equipment, Security and Surveillance Systems.
Industrial Automation and Control
The A3P1000-1FGG256M fits industrial control and automation boards that need flexible glue logic, sensor-interface bridging, and motor-control sequencing in a single nonvolatile chip. Its 11,000 logic elements and 177 user I/Os across four independently supplied I/O banks let one device absorb multiple discrete PLDs and interface translators, cutting BOM count. Its 1.5V core keeps dynamic power low, and because configuration is stored in on-chip flash, the controller is ready the instant 1.5V and bank I/O voltages stabilize - important for factory equipment that must not miss power-cycle events. Place it between backplane connectors and a main MCU or SoC, assigning bank voltages to match the mixed 3.3V/2.5V/1.8V standards typical of industrial I/O.
おすすめ
Aerospace and Defense Subsystems
Instant-on, single-chip nonvolatile configuration makes ProASIC3 a long-standing choice for aerospace and defense boards where no configuration-readback or external boot device is acceptable. The A3P1000-1FGG256M provides 1M gates for interface bridging, housekeeping, and bitstream-agnostic telemetry functions in avionics and payload electronics. Its flash fabric resists configuration scrubbing requirements that SRAM FPGAs impose, reducing system complexity. Note that this commercial-grade M part is rated 0C to +85C; defense programs should evaluate the industrial (I) or automotive/hi-rel grades in the same FGG256 footprint, which are pin-compatible drop-ins. Power it from a 1.5V core rail with independent VCCIBx banks for mixed-voltage legacy interfaces.
おすすめ
Communication Interface Bridging
With 177 user I/Os and four I/O banks, the A3P1000-1FGG256M is well suited to protocol and voltage bridging - translating between legacy parallel buses, SPI/UART aggregates, and backplane signaling on communications line cards and baseband boards. ProASIC3's system performance is sufficient for the control and data-movement plane in such designs, while its embedded 147,456-bit RAM buffers packet fragments or FIFO crossings. Because I/O bank supplies are independent, one chip can terminate 3.3V legacy edges on one bank and 1.8V high-speed signals on another without level shifters, saving board area in the 256-ball 17mm-class BGA footprint.
おすすめ
Portable and Battery-Powered Instrumentation
Handheld instruments benefit from the A3P1000-1FGG256M's low static-power flash fabric and instant-on behavior: measurement front ends built around it begin operating the moment power is applied, with no multi-hundred-millisecond configuration delay typical of SRAM FPGAs. The 1.5V core minimizes dynamic energy, and the single-chip solution removes the configuration flash that adds quiescent and leakage paths in portable designs. Its 256-LBGA package conserves PCB area in the measurement head. Designers should budget the -1 speed grade timing for state machines and averaging logic rather than high-throughput DSP, where an SRAM device would remain preferable.
おすすめ
Medical Diagnostic Equipment
Benchtop diagnostic and patient-interface equipment uses the A3P1000-1FGG256M for deterministic, instantly-available sequencing and safety interlock logic. The nonvolatile flash fabric means interlock and watchdog state machines are active from power-on, a property regulators and safety reviewers favor for single-fault analysis, and the absence of an external bitstream simplifies configuration-control documentation. The 11,000-LE fabric comfortably implements timing generators for sensors, filter front ends, and communication wrappers to a host PC or network. Use the four VCCIBx banks to match patient-side isolation interfaces and host-side 3.3V logic on one device.
おすすめ
Security and Surveillance Systems
Video surveillance and access-control boards use the A3P1000-1FGG256M as camera-interface glue: deserialization wrappers, frame FIFOs built from its 147,456-bit embedded RAM, sensor timing generation, and PCIe/CPI bridging to a compression SoC. Flash configuration gives tamper-resistant, instant-on startup so cameras begin streaming the moment power arrives, and reprogrammability allows in-field feature updates over the maintenance UART. The 177 I/Os handle multi-sensor arrays with the four banks mapped to different I/O voltages, and the 256-ball BGA keeps the logic footprint compact inside dome or bullet camera housings.

主な差別化要因

- Wider temperature option without respin （vs A3P1000-1FGG256I)
設計ノート
The A3P1000-1FGG256M needs a 1.5V core rail (VCC) plus four independent I/O bank rails (VCCIB0-VCCIB3). Assign each bank a single voltage standard - the migration application note confirms VCCIBx pins route through their corresponding banks, so mixed-standard I/Os cannot share a bank. Estimated: a conservative point-of-load design targeting ~300 mA per I/O bank plus core current typical of 1M-gate flash fabric at moderate toggle rates should use regulators with at least 50% headroom; confirm actual current in Libero SmartPower after place-and-route.
The FBGA-256 footprint requires controlled-depth via-in-pad or dog-bone escape routing; define the pad stack per Microchip's FGG256 package mechanical drawing in datasheet DS50003269. Place 0.1uF ceramic decoupling within 2-3 mm of each VCC/VCCIBx ball pair, and add bulk 10uF per bank. The FGG256 ball pitch demands precision stencil design - use the manufacturer-recommended land pattern rather than a generic BGA-256 footprint to avoid solder bridging.
The -1 speed grade is the slowest in the A3P1000 family; do not port timing-critical designs from faster grades without re-running static timing analysis in Libero SoC. Also, the ProASIC3 datasheet (DS50003269) notes that some detailed device/package thermal information does not apply to the A3P1000 - obtain the A3P1000-specific thermal data from Microchip before performing junction-temperature estimates. Finally, the 'M' suffix is commercial temperature (0C to +85C); selecting 'I' grade costs little more and avoids field failures in hot enclosures.
コンプライアンス情報
The provided web data does not state RoHS/REACH status for the M suffix specifically. Microchip also publishes a separate Automotive ProASIC3 datasheet (DS50003485) for automotive-qualified variants; this commercial M part has no AEC-Q100 claim in the retrieved data. Verify compliance on the Microchip product page before design-in.
