Logic density and I/O — what 1280 LEs and 96 I/O mean for a glue-logic FPGA
The ICE40HX1K-TQ144 packs 1280 logic elements (160 LABs/CLBs) and 64 Kbit of block RAM, enough to absorb a handful of 8-bit counters, a small state machine, and a SPI bridge without leaving the iCE40 HX family's low-power envelope. 96 user I/O in a 144-TQFP (20x20 mm) means every available pin on the package is an I/O — no power-dedicated pins beyond the core and PLL supplies — so the pinout is dense and the board layout needs to account for the 1.14 V to 1.26 V core rail being clean within 50 mV.
Tray packaging means the devices are delivered in antistatic trays, not tape-and-reel — a pick-and-place machine can handle trays, but the feeder setup differs from reel-fed lines.
Active lifecycle and compliance — no LTB risk on this code
ROHS3 compliant and the base part number ICE40 covers the whole iCE40 family, so the same compliance documentation applies across the HX and LP variants.
