FPGAs (Field Programmable Gate Array) With Microcontrollers Procurement Notes

Verify the specific package variant corresponding to the 'BQC' suffix against official Microchip documentation, as the provided datasheet lists BG256 and LQ144 options for the AT94S10 family. Confirm that the required voltage range of 3.0V to 3.6V aligns with the target system design. Ensure compatibility with the ATDH2225 programming cable or equivalent ISP tools for configuration memory updates.

FPGAs (Field Programmable Gate Array) With Microcontrollers Selection Notes

Select this component when a combination of FPGA logic density (10K gates) and microcontroller functionality is required in a single package. The AT94S10AL provides a balance of gate count and memory compared to the 5K and 40K variants. Consider the 3.3V PCI-compliant I/O structure and 5V tolerance for interfacing with mixed-voltage peripherals. Verify that the SRAM-based nature of the FPGA meets the reconfigurability needs of the application.

FPGAs (Field Programmable Gate Array) With Microcontrollers Part Context

The AT94S series belongs to the Secure FPSLIC family, combining Atmel's AT40K FPGA technology with AVR microcontrollers and AT17 Series configuration memories. This integration allows for dynamic reconfiguration and cache-like performance. The AT94S10AL specifically targets applications needing moderate FPGA resources alongside robust microcontroller control and secure boot capabilities.

FPGAs (Field Programmable Gate Array) With Microcontrollers Replacement Considerations

The AT94S05AL and AT94S40AL are part of the same family, offering 5K and 40K gates respectively, with identical pinouts and architecture. Cross-referencing should focus on gate count and SRAM requirements. No direct third-party substitutes are documented in the source material; alternative solutions would require architectural redesign.
