FAQ

What is the maximum operating junction temperature for XC7A25T-1CPG238I?

The XC7A25T-1CPG238I has a maximum operating junction temperature of 100°C, validated under industrial temperature grade (-40°C to +100°C ambient). This rating enables deployment in sealed enclosures with limited airflow, such as motor drive cabinets or factory-floor vision modules, provided thermal vias and copper pour are implemented per AMD's AN123 guidelines.

Does XC7A25T-1CPG238I support DDR3 memory interfaces?

Yes, XC7A25T-1CPG238I includes a hardened DDR3/DDR3L memory controller supporting data rates up to 800 Mbps. It implements write-leveling, read-leveling, and gate training sequences in hardware, reducing FPGA logic overhead and enabling reliable 32-bit wide memory subsystems in industrial controllers and vision preprocessors.

Can XC7A25T-1CPG238I be configured via JTAG only?

No - XC7A25T-1CPG238I supports JTAG for debugging and programming, but primary configuration requires Master SPI, Slave SelectMAP, or BPI modes. JTAG alone cannot load the full bitstream into configuration memory; it is used for boundary scan, debug access, and partial reconfiguration triggers after initial configuration.

What I/O standards are supported by XC7A25T-1CPG238I?

XC7A25T-1CPG238I supports 21 I/O standards including LVCMOS (1.2V–3.3V), LVDS_25, BLVDS, RSDS, SSTL15, SSTL18, HSTL_I, and differential signaling with internal termination. Each I/O bank is independently powered, allowing mixed-voltage operation across different interface domains on a single device.

Is XC7A25T-1CPG238I pin-compatible with other Artix-7 devices in the CP package?

XC7A25T-1CPG238I shares the 238-pin CP package with select Artix-7 variants, but pin compatibility is not guaranteed across all models. For example, XC7A15T-1CPG236I uses a 236-pin variant with different ball count and mapping. Always verify pinout alignment using AMD UG470 and device-specific package drawings before board reuse.
