The new devices, dubbed UltraPlus, have more memory (1.1 Mbit RAM), twice the digital signal processors (8x DSPs), and improved I/Os over previous generations.
Typically they are used for application specific processing offload in battery-powered systems. These applications include: voice recognition, gesture recognition, image recognition, haptic and graphics acceleration.
According to Lattice: “More DSPs offer the ability to compute higher- quality algorithms, while increased memory allows data to be buffered for longer low-power states. The flexible I/Os enable a more distributed heterogeneous processing architecture.”
Product features include:
- 1.1 Mbit SRAM, 8 DSP blocks, up to 5K LUTs and non-volatile configuration
- MIPI-I3C support for low-resolution, always-on camera applications
- Sub 100uW standby power consumption
- Package size as small as 2.15 x 2.55mm
“The iCE40 UltraPlus FPGAs expand its market reach to system designers who require FPGA functionality with improved DSP compute power, more I/Os and increased memory for buffering,” said C.H. Chee, senior director of marketing, mobile & consumer division at Lattice Semiconductor.
