The AX500-1PQ208I is a high-performance Field Programmable Gate Array (FPGA) integrated circuit manufactured by Micrel/Microchip Technology, belonging to the Axcelerator series of embedded FPGAs. This sophisticated programmable logic device addresses the critical design challenge of providing flexible, reconfigurable digital logic solutions for complex electronic systems that require custom processing capabilities without the time and cost associated with developing application-specific integrated circuits (ASICs).
The device features an impressive 500,000 gates of programmable logic capacity organized into 8,064 Logic Array Blocks (LABs) or Configurable Logic Blocks (CLBs), providing substantial computational resources for implementing complex digital designs. With 115 input/output pins available in a 208-pin Quad Flat Pack (QFP) surface-mount package measuring 28x28mm, this FPGA offers excellent connectivity options while maintaining a compact footprint suitable for space-constrained applications. The integrated 73,728 bits of RAM provide essential on-chip memory resources for data buffering, lookup tables, and temporary storage requirements.
Operating within a supply voltage range of 1.425V to 1.575V and designed to function reliably across an industrial temperature range of -40°C to 85°C, this FPGA demonstrates robust performance characteristics suitable for demanding environmental conditions. The surface-mount 208-PQFP package configuration facilitates automated assembly processes and ensures reliable mechanical and electrical connections in production environments.
The primary advantages of this FPGA include its substantial gate count enabling complex algorithm implementation, generous I/O capacity supporting extensive system interfacing, integrated RAM reducing external memory requirements, and the inherent flexibility of field-programmable architecture allowing for design modifications and updates without hardware changes. The industrial temperature rating and compact package make it particularly suitable for embedded applications where reliability and space efficiency are paramount.
This device finds extensive application in telecommunications infrastructure, industrial automation systems, digital signal processing applications, embedded computing platforms, prototyping and development systems, and custom logic implementations where standard microprocessors or microcontrollers cannot meet specific performance or functionality requirements. The combination of high gate density and substantial I/O resources makes it ideal for applications requiring complex data processing, protocol conversion, interface bridging, and real-time control functions.
Equivalent and alternative models in the FPGA market include the Xilinx Spartan-3 series (particularly XC3S500E), Altera Cyclone II series (EP2C20 and EP2C35), Lattice ECP2 series devices, Actel ProASIC3 family components, and other members of the Microsemi Axcelerator family such as AX250 and AX1000 variants. These alternatives offer similar gate densities and I/O capabilities, though specific features, power consumption, and pricing may vary. The Xilinx XC3S500E provides comparable logic capacity with different architecture optimizations, while Altera's Cyclone II EP2C20 offers similar performance characteristics with alternative development tool ecosystems. When selecting among these options, designers typically consider factors including development tool preferences, specific feature requirements, power consumption constraints, cost considerations, and long-term product availability.
