Product details
Lattice Semiconductor ICE40LP1K-CM81 - iCE40 LP FPGA
The ICE40LP1K-CM81 keeps the 1,280-logic-cell iCE40 LP engine but trades the tiny CM36 footprint for I/O: 63 user pins on an 81-ball ucBGA (4 × 4 mm). With 64 kb of EBR, one PLL and 12 differential input pairs available, it suits bridge and interface-expansion designs that need more pins than the 36-ball package can offer.
Key Features
- 1,280 logic cells (LUT4 + FF), 40 nm low-power process
- 64 kb EBR (16 × 4 kb blocks) plus distributed RAM
- 1 PLL; 8 global clock networks
- 63 user I/O on 0.4 mm pitch - 2.5× the CM36 pin count
- Up to 12 differential input pairs; sysIO 1.2–3.3 V
- Configuration via on-chip NVCM or external SPI

Frequently Asked Questions
Q: Why CM81 over CM36?
A: 63 vs 25 user I/O in a 4 × 4 mm package - the choice is pin count against board area.
Q: Does the pinout migrate to larger iCE40?
A: Yes - the CM81 footprint is shared across LP/HX densities up to CM81, so you can move to LP4K/LP8K without a respin.
Q: Is it reprogrammable?
A: SRAM fabric plus NVCM: unlimited reconfiguration over SPI; NVCM burn is one-time.
