Compact wristwatch form factor FPGA is smaller than MCUs

Based on the iCE40 Ultra FPGA, Lattice Semiconductor offers a development platform for designing low-power wearable devices.
The FPGA uses a package that is 60% smaller than alternative microcontrollers, says the company. It also supports a low power standby mode for always-on functionality, suitable for wearables that need to operate for days between charges.
Hardware features and sensors supported include a 1.54inch display, MEMS microphone, high-brightness LED, IR LED, BLE module and 32Mbyte of flash memory. There is also support for sensors capable of measuring heart rate/SpO2, skin temperature, and pressure as well as an accelerometer and gyroscope.
The wrist watch form factor measures 1.5 x 1.57 x 0.87inches, with a wrist strap and a built in battery.
A user guide and several demos are included to showcase parallel RGB to MIPI DSI bridging, health monitor, pedometer, IR transmitter or flashlight functions.
