iCE40 UltraLite™ Field Programmable Gate Array (FPGA) IC 26 57344 1248 36-VFBGA

General Description

iCE40 UltraLite family is an optimum logic, smallest footprint, low I/O count ultra-low power FPGA and sensor manager

with instant on capability. It is designed for ultra-low power mobile applications, such as smartphones, tabletsand

hand-held devices. The iCE40 UltraLite family includes integrated blocks to interface with virtually all mobile sensors and

application processors. The iCE40 UltraLite family also features two 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 beused for awaken activities.

The hardened RGB PWM IP, with the three 24 mA constant current RGB LED outputs on the iCE40 UltraLite provides all

the necessary logic to directly drive the service LED, without the need of external MOSFET or buffer.

The 400 mA constant current IR driver output provides a direct interface to external LED for application such as IrDA

functions. Users simply implement the hardened TX/RX pulse logic that meets their needs, and connect the IRdriver

directly to the LED, without the need of external MOSFET or buffer. The 100 mA Barcode Emulation driveroutput provides

a direct interface for applications such as barcode scanning. The 100 mA and 400 mA drivers canalso be combined to be

used as a 500 mA IR driver if higher than 400 mA current drive is required.

The iCE40 UltraLite family of devices are targeting for mobile applications to perform functions such as IrDA, Service LED,

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

The iCE40 UltraLite family features two device densities of 640 or 1K Look Up Tables (LUTs) of logic with programmable

I/Os that can be used as an interface port or general purpose I/O. It also has up to 56 kbits of Block RAMs towork with

user logic.
