Device identity and logic fabric
The XC6SLX16-2CSG225I is a member of the AMD Spartan-6 LX family, a low-power FPGA architecture built on a 45 nm process. It delivers 14,579 logic cells organised into 1,139 configurable logic blocks (CLBs/LABs), providing the fabric for glue logic, state machines, or lightweight DSP datapaths. On-chip block RAM totals 589,824 bits, sufficient for small FIFOs, line buffers, or coefficient storage without external memory. The 160 user I/O pins, accessible through the 225-ball CSPBGA package (13 mm × 13 mm), support single-ended and differential standards up to the bank voltage limits.
Supply rails and temperature grade
Core logic operates from a 1.14 V to 1.26 V supply rail, typical of the 45 nm low-power process. The 225-CSPBGA package (supplier device package 225-CSPBGA, 13 mm × 13 mm) requires a 4- to 6-layer PCB for fan-out of the 160 I/O and the core supply decoupling. The 0.8 mm ball pitch is compatible with standard assembly processes; a solder mask defined pad is recommended for reliable ball attach.
Lifecycle and compliance
The device is ROHS3 compliant, meeting the current exemption-free restriction levels for lead, mercury, and cadmium.
