iCE40 UltraPlus™ Field Programmable Gate Array (FPGA) IC 39 1171456 5280 48-VFQFN Exposed Pad

General Description

iCE40 UltraPlus™ family from Lattice Semiconductor is an ultra-low power FPGA and sensor manager designed for

ultra-low power mobile applications, such as smartphones, tablets and hand-held devices. iCE40 UltraPlus is compatible

with Lattice's iCE40 Ultra family devices, containing all the functions iCE40 Ultra family has except the high current IR LED

driver. In addition, the iCE40 UltraPlus features an additional 1 Mb SRAM, additional DSP blocks, with additional LUTs, all

which can be used to support an always-on Voice Recognition function in the mobile devices, without the need to keep

the higher power consuming voice codec on allthe time.

The iCE40 UltraPlus family includes integrated SPI and I²C blocks to interface with virtually all mobile sensors and

application processors. In addition, the iCE40 UltraPlus family also features two I/O pins that can support the interface to

I3C devices. There are two on-chip oscillators, 10 kHz and 48 MHz, the LFOSC (10 kHz) is ideal for low power function in

always-onapplications, while HFOSC (48 MHz) can be used for awaken activities.

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

sent from the mobile device, such as voice data. The RGB PWM IP, with the three 24 mA constant current RGB outputs on

the iCE40 UltraPlus provides all the necessary logic to directly drive the service LED, without the need of external MOSFET

or buffer.

The iCE40 UltraPlus family of devices are targeting for mobile applications to perform all the functions in iCE40 Ultra

devices, such as Service LED, GPIO Expander, SDIO Level Shift, and other custom functions. In addition, the iCE40

UltraPlus family devices are also targeting for Voice Recognition application.

The iCE40 UltraPlus family features two device densities, 2800 to 5280 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. Two of the iCE40 UltraPlus I/Os can be

used to interface to higher performance I3C. It also has up to 120 kb of Block RAMs, plus 1024 kb of Single Port SRAMs

to work with user logic.
