FPGAs (Field Programmable Gate Array) With Microcontrollers Procurement Notes

Verify the specific ordering suffix '25DGC' against the manufacturer's current datasheet to confirm package type (CABGA), temperature range (Commercial 0°C to 70°C), and speed grade (25 MHz). Ensure compatibility with the required 3.0V to 3.6V supply voltage and 5V tolerant I/O levels for the target system design.

FPGAs (Field Programmable Gate Array) With Microcontrollers Selection Notes

Select this component when a combined FPGA and microcontroller solution is needed within a single multi-chip module. The AT94S05AL variant provides 5,000 FPGA gates, which is suitable for moderate complexity logic designs compared to the 10K or 40K gate variants in the AT94S family. Consider the 256-pin CABGA package constraints and the need for ISP programming infrastructure during the design phase.

FPGAs (Field Programmable Gate Array) With Microcontrollers Part Context

The AT94S05AL-25DGC belongs to the AT94S Secure FPSLIC family, which combines Atmel's AT40K FPGA technology with AVR microcontrollers and AT17 Series configuration memories. This family allows for partially or fully reconfigurable FPGA cores without loss of data, enabling dynamic system updates while maintaining the processing capabilities of the embedded AVR core.

FPGAs (Field Programmable Gate Array) With Microcontrollers Replacement Considerations

For higher logic density, consider the AT94S10AL series (10K gates) or AT94S40AL series (40K gates) which share similar architectural features but offer increased FPGA resources and I/O counts. Verify pinout compatibility if substituting within the same package style.
