The ICE40LP1K-CM49: The 49-VFBGA package (3x3 mm body) with 0.5 mm ball pitch demands a 4-layer PCB for fan-out — the inner rows of the 35 I/O balls break out cleanly on layer 2, but the centre ground and supply balls need a via-in-pad or microvia process to avoid routing congestion. Supply voltage is 1.14 V to 1.26 V — a 1.2 V rail with ±3 % regulation keeps the core within spec; the narrow window means the regulator's load transient response matters more than its nominal accuracy.
Logic capacity and memory
1280 logic cells (160 LABs/CLBs) and 65536 total RAM bits — this is a glue-logic FPGA sized for small state machines, sensor interface bridging, or display timing control where a CPLD runs out of registers.
Temperature grade and sourcing posture
Suitable for outdoor telecom, motor-drive control, or under-hood auxiliary modules that stay below the 100°C junction ceiling.
