Compact ultra low-power FPGAs for feature-rich mobile devices
Mouser is now stocking the Lattice Semiconductor iCE40 UltraLite FPGA one of
the industry's smallest and lowest power field programmable gate arrays
(FPGAs) for feature-rich consumer mobile and industrial handheld devices.
The highly-integrated iCE40 UltraLite devices deliver a flexible logic
architecture, programmable I/Os, and hardened IPs and LED drivers - all
wrapped into an ultra-low power FPGA and sensor manager with instant-on
capability. Designed to accelerate time-to-market with their robust feature
sets, the iCE40 UltraLite FPGAs consume 30 percent less power with a 68
percent smaller footprint than similar FPGAs.
The devices are based on an advanced 40nm ultra-low power process. Available
in densities of 640 or 1K logic cells, the FPGAs come equipped with up to 56
Kbits sysMEM(tm) Embedded Block RAM (EBR) to work with user logic, and
feature two on-chip oscillators: a 9.7 kHz LFOSC and a 48 MHz HFOSC. The
LFOSC is ideally suited for always-on low-power applications, and the HFOSC
can be used for awaken activities.
The FPGAs come with a hardened RGB PWM IP and three user-configurable 24 mA
constant-current RGB drive outputs. An on-chip 400 mA current drive IR LED
output provides a direct interface to an external LED for IrDA
functionality. The 100 mA barcode emulation driver output provides a direct
interface for applications such as barcode scanning, while the IR LED output
and learning mode capabilities can be used to drive applications such as TV
The iCE40 UltraLite FPGAs achieve flexible, reliable, and secure SRAM memory
configuration on through a standard SPI interface and internal nonvolatile
configuration memory (NVCM). Since the memory configuration can be stored in
nonvolatile (one-time programmable) on-chip memory, no external
configuration memory or circuitry is required.
They are available in either a 16-ball WLCSP package with a 0.35 mm ball
pitch and 1.409mm2 footprint, or a 36-ball BGA package with a 0.4mm ball
pitch and 2.5mm2 footprint. The iCE40 UltraLite FPGAs are a perfect solution
for a variety of small, power-sensitive Internet of Things (IoT) or wireless
applications, including smartphones, tablets, medical devices, wearable
devices, multi-sensor management, and RGB lighting controls, says the
