APA150-TQ100I Overview
A Field Programmable Gate Array (FPGA) is a reprogrammable semiconductor device built from an array of configurable logic blocks (CLBs), programmable routing, and dedicated memory and I/O resources, sitting in the broader taxonomy of programmable logic devices (PLD) -> logic ICs -> integrated circuits. The ProASICPLUS family is notable because it is nonvolatile and live-at-power-up, combining the instant-on behavior of ASICs with the flexibility of SRAM-based FPGAs, eliminating the need for external boot PROMs and avoiding the configuration-time power-up glitches common to SRAM FPGAs.
Key features of the APA150-TQ100I include 150K system gates, 36 kbits of embedded two-port SRAM, an integrated PCI core that supports 32-bit, 33/66 MHz PCI operation, Schmitt-trigger input option for noisy industrial environments, and IEEE 1149.1 boundary-scan (JTAG) for board-level test access. The 0.22-micron CMOS process delivers low static power relative to SRAM-based equivalents and high noise immunity.
The device is fabricated on a 0.22 um CMOS process and uses flash-based switch technology, which is nonvolatile and reprogrammable. This architecture supports live-at-power-up single-chip operation, removes the external configuration memory, and provides inherent design security through the on-chip flash cells. Performance is bounded by the 350 MHz internal / 180 MHz external system frequency figures and by 3.3V, 32-bit PCI support up to 50 MHz.
Typical applications include industrial control and factory automation, telecom interface cards, low-volume ASIC replacement, secure firmware IP cores, and embedded glue logic around microcontrollers. The 2.5V core, 3.3V I/O PCI support and industrial temperature grade also make it suitable for legacy industrial bus bridges.
When designing with this FPGA, plan power sequencing so that the 2.5V core rail comes up cleanly before the 3.3V I/O rail drives signal lines, and use Microchip's Libero IDE or Designer toolchain for place-and-route. Decoupling should follow the 0.1 uF-per-power-pin guideline plus bulk caps per supply domain.

Typical Applications
APA150-TQ100I is suitable for 6 applications: Industrial Control and Factory Automation, PCI Interface Card for Legacy PCs, ASIC Replacement for Low-Volume Designs, Secure Firmware and IP Protection, Embedded Glue Logic Around Microcontrollers, Telecom Interface and Bridge Cards.
Industrial Control and Factory Automation
The APA150-TQ100I is well suited to industrial control and factory-automation designs thanks to its -40C to +85C industrial temperature rating and 2.5V core / 3.3V I/O operation. Its 66 user I/Os can directly interface 3.3V digital sensors, motor-control drivers, and HMI displays without external level shifters, while the 36 kbits of two-port SRAM act as a dual-buffer between sensor data and the host MCU. The nonvolatile flash configuration means the design boots deterministically into a known logic image even after brown-outs and noisy power events on the factory floor, eliminating the FPGA re-glitch problems common to SRAM-based equivalents.
Recommended
PCI Interface Card for Legacy PCs
The APA150-TQ100I includes a built-in 3.3V, 32-bit PCI core that supports up to 50 MHz PCI operation, allowing the FPGA to drop into legacy PCI add-in cards without an external PCI bridge chip. Its 150K system gates provide enough headroom for a custom register set, scatter-gather DMA engine, and interrupt logic, while the 36 kbits of two-port SRAM implement shared mailboxes between the host driver and on-card firmware. The 66 user I/Os fan out to onboard peripherals, and the nonvolatile live-at-power-up behavior lets the card enumerate the moment the system powers on, important for headless servers and instrumentation hosts.
Recommended
ASIC Replacement for Low-Volume Designs
For low-volume designs that need ASIC integration but cannot absorb a $1M+ NRE mask charge, the APA150-TQ100I delivers 6,144 logic cells and 150K system gates in a reprogrammable flash-based package. Designers can iterate the Verilog/VHDL netlist in software and re-flash the device in seconds, then freeze the design for production without retooling. The 0.22 um CMOS process and 2.5V core deliver lower dynamic power than equivalent SRAM FPGAs, which matters for sealed enclosures with limited thermal headroom.
Recommended
Secure Firmware and IP Protection
Because the APA150-TQ100I stores its configuration in on-chip flash cells rather than in an external bitstream, the design IP cannot be intercepted at power-up, addressing the bitstream-theft vulnerability of SRAM-based FPGAs. This makes the device attractive for secure boot controllers, cryptographic accelerators, and tamper-evident firmware modules. The 150K system gates fit a typical AES/SHA accelerator plus key-storage glue logic, and the industrial temperature grade keeps the device reliable in outdoor secure enclosures.
Recommended
Embedded Glue Logic Around Microcontrollers
The APA150-TQ100I acts as a flexible glue-logic companion to a host MCU or DSP, implementing custom bus bridges, wide multiplexers, and timing-sensitive peripherals that do not fit neatly into the MCU's peripheral set. The 66 user I/Os route directly to 3.3V logic with Schmitt-trigger option, the 36 kbits of SRAM buffer burst-mode transfers, and the 350 MHz internal performance handles 100 MHz+ parallel buses comfortably. The nonvolatile configuration means the FPGA starts in the correct state every MCU boot, eliminating race conditions during power-up.
Recommended
Telecom Interface and Bridge Cards
Telecom interface cards benefit from the APA150-TQ100I's live-at-power-up behavior and PCI support, which lets the FPGA present a deterministic card image to the host CPU during system bring-up. The 150K gates fit T1/E1 framers, HDLC controllers, and custom serial protocol engines, while the 3.3V I/O bank interfaces directly to telecom line-interface units without level translation. Industrial temperature rating supports outdoor base-station enclosures and central-office equipment bays.

- Higher logic density on TQFP-100 footprint (vs APA300-TQG100I)
Design Notes
The APA150-TQ100I requires a clean 2.5V core rail and a 3.3V I/O rail. Per the ProASICPLUS datasheet, place one 0.1 uF decoupling capacitor within 5 mm of every VCC and VCCIO pin, plus a 10 uF bulk capacitor per supply domain. Power-up sequence is not strictly enforced because the device is live at power-up, but a monotonic 2.5V ramp avoids inrush latch-up on the internal charge pumps.
Route JTAG signals TCK, TMS, TDI, and TDO with 50 ohm controlled impedance and length-matched within 25 mm to avoid TAP-controller state-machine errors. Keep JTAG traces away from clock and switching-power lines to prevent 1149.1 boundary-scan false triggers; route GND as a continuous pour under the TQFP-100 thermal pad-adjacent ground pins for clean return paths.
Estimated: at 350 MHz internal toggle rate and 0.22 um CMOS, the APA150-TQ100I core dissipation is typically 0.4 W to 0.8 W. The TQFP-100 package theta_JA is approximately 38 C/W on a 4-layer JEDEC test board, so the junction-to-ambient temperature rise is roughly 15C to 30C. For sealed enclosures with no airflow, derate the toggle rate to freeup thermal margin and add a copper pour under the package.
Do not substitute the APA150-TQ100I with the APA150-TQ100 commercial variant if the application sees -20C or colder start-up - the commercial part is only rated to 0C. Do not exceed 3.6V on any VCCIO pin or 2.7V on any VCC pin, even briefly; the flash configuration cells can latch into a soft-error state that requires a full re-flash.
Compliance Information
The TQ100 leaded package is non-RoHS; the TQG100 variant is the RoHS drop-in upgrade. Not AEC-Q100 qualified - ProASICPLUS is industrial-grade, not automotive-grade; consider ProASIC3 or IGLOO2 for AEC-Q100.
