iCE40 Ultra™ Field Programmable Gate Array (FPGA) IC 39 65536 1100 48-VFQFN Exposed Pad

General Description

iCE40 Ultra family is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications,

such as smartphones, tablets and hand-held devices. The iCE40 Ultra family includes integrated SPI and I²Cblocks to

interface with virtually all mobile sensors and application processors. The iCE40 Ultra family also featurestwo on-chip

oscillators, 10 kHz and 48 MHz. The LFOSC (10 kHz) is ideal for low power function in always-on applications, while

HFOSC (48 MHz) can be used for awaken activities.

The iCE40 Ultra family also features DSP functional block to off-load Application Processor to pre-process information

sent from the mobile sensors. The embedded RGB PWM IP, with the three 24 mA constant current RGB outputs on the

iCE40 Ultra provides all the necessary logic to directly drive the service LED, without the need ofexternal MOSFET or

buffer.

The 500 mA constant current IR driver output provides a direct interface to external LED for application such asIrDA

functions. Users simply implement the modulation logic that meets his needs, and connect the IR driverdirectly to the

LED, without the need of external MOSFET or buffer. This high current IR driver can also be used asBarcode Emulation,

sending barcode information to external Barcode Reader.

The iCE40 Ultra family of devices are targeting for mobile applications to perform functions such as IrDA, ServiceLED,

Barcode Emulation, GPIO Expander, SDIO Level Shift, and other custom functions.

The iCE40 Ultra family features three device densities, from 1100 to 3520 Look Up Tables (LUTs) of logic with

programmable I/Os that can be used as either SPI/I²C interface ports or general purpose I/O’s. It also has up to 80kbits

of Block RAMs to work with user logic.
