Product details
Lattice Semiconductor ICE40UL640-CM36AI - iCE40 UltraLite FPGA
The ICE40UL640-CM36AI is a member of Lattice's iCE40 UltraLite family, built for one job: keeping small always-on functions alive at microwatt budgets inside mobile and battery-powered products. It packs 640 LUTs, 56 kb of sysMEM block RAM and a PLL into a 36-ball ucBGA measuring just 2.5 × 2.5 mm, and configures itself from on-chip NVCM or external SPI flash at power-up - no external boot device needed.
Key Features
- 640 LUTs (640 logic cells) on a 40 nm low-power process
- 56 kb sysMEM EBR plus distributed RAM for FIFOs and buffers
- One sysCLOCK PLL; hardened 48 MHz and 10 kHz oscillators
- Hardened RGB PWM and IR TX/RX controllers, two I2C cores
- Static power ≈ 35 µA; 10/100/400 mA LED sink drivers on chip
- 36-ball ucBGA (2.5 × 2.5 mm, 0.4 mm pitch), 26 user I/O, industrial temp

Typical Applications
Per Lattice's iCE40 UltraLite data sheet (FPGA-DS-02027) and family page, UltraLite devices target smartphones, tablets and consumer handhelds, multi-sensor management, IR remote and barcode emulation, RGB light control, and ultra-low-power sensor management in wearables and hearables where the main SoC stays asleep.

Frequently Asked Questions
Q: How is UltraLite different from iCE40 LP?
A: UltraLite adds hardened RGB/IR LED controllers, two oscillators and higher-current LED sinks on the same low-power fabric - it is aimed at mobile sensing and indicator duties rather than general glue logic.
Q: Does it need an external boot flash?
A: No - the bitstream lives in the on-chip NVCM. NVCM is one-time programmable; develop over SPI, then burn once for production.
Q: What toolchain is supported?
A: Lattice iCEcube2 (free) and Diamond Programmer; iCE40 UltraLite is also supported by the open-source IceStorm flow.
