A3P250L-1VQG100I

Field Programmable Gate Array Overview

The A3P250L-1VQG100I is a ProASIC3L Flash FPGA manufactured by Microsemi Corporation. It features 250,000 system gates and 71 I/Os in a 100-VQFP package. The device operates on a core voltage range of 1.14 V to 1.575 V with a maximum frequency of 350 MHz. Embedded memory includes 36 kbits of True Dual-Port SRAM. It supports industrial temperature ranges from -40°C to +100°C and utilizes a 130-nm CMOS process for instant-on non-volatile configuration.

Field Programmable Gate Array Feature Summary

• Instant-on non-volatile Flash technology eliminates the need for external configuration memory.
• Supports mixed-voltage I/O standards including 1.5 V, 1.8 V, 2.5 V, and 3.3 V operation.
• Enables in-system programming via JTAG using AES decryption security.

Field Programmable Gate Array Applications

• Industrial control systems requiring instant power-up functionality
• Automotive electronics operating in extended temperature environments
• Communication infrastructure equipment needing secure configuration

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'L' indicates the low-power variant with a 1.14 V minimum core voltage, distinct from standard ProASIC3 devices. Confirm the '-1' speed grade corresponds to the 350 MHz performance target. Ensure the VQG100 package matches the required footprint and pinout for the design. Check current availability status as legacy FlashFPGA lines may have limited production runs.

Field Programmable Gate Array Selection Notes

Select this component when non-volatile configuration without external PROMs is required. The low-voltage core (1.14 V) makes it suitable for battery-powered or energy-efficient applications compared to standard ProASIC3 parts. Verify that the 250k gate count and 36 kbit RAM meet the logic density requirements. Ensure the 100-pin VQFP package fits the board space constraints.

Field Programmable Gate Array Part Context

This part belongs to the ProASIC3L family, which offers lower power consumption than the standard ProASIC3 series while maintaining similar logic capacity. It serves as a bridge between small ASICs and larger FPGAs, providing cost-effective solutions for mid-density logic applications. The device integrates ARM Cortex-M1 support options in other variants within the broader ProASIC3 portfolio.

Field Programmable Gate Array Replacement Considerations

Direct replacements include the A3P250-VQG100I if the higher core voltage (1.425 V min) is acceptable. For upgraded performance, consider the A3P060 or A3P125 families if gate counts allow. Legacy Actel equivalents may require retiming due to architectural differences in routing and I/O banks.
