Mouser stocks compact UltraLite FPGAs from Lattice
FPGAs designed for mobile devices from Lattice Semiconductor are available through the distributor, Mouser.
The iCE40 UltraLite FPGAs are part of Lattice Semiconductor’s iCE40 Ultra family, and are claimed to be one of the industry’s smallest and lowest power FPGAs for feature-rich consumer mobile and industrial handheld devices. The integrated devices deliver a flexible logic architecture, programmable I/Os, and hardened IPs and LED drivers with a low power FPGA and sensor manager with instant-on capability.
According to the company, they consume 30% less power with a 68% smaller footprint than similar FPGAs.
The FPGAs are based on an advanced 40nm ultra-low power process. Density options are 640 or 1K logic cells. They also have up to 56kbits sysMEM Embedded Block RAM (EBR) to work with user logic, and feature two on-chip oscillators: a 9.7kHz LFOSC and a 48MHz HFOSC. The LFOSC is suited for always-on low-power applications, and the HFOSC can be used for awakening activities.
A hardened RGB PWM IP and three user-configurable 24mA constant-current RGB drive outputs are also included. An on-chip 400mA 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 remote controls.
A standard SPI and internal, non-volatile configuration memory (NVCM) secure the SRAM. Memory configuration can be stored in non-volatile (one-time programmable) on-chip memory, so no external configuration memory or circuitry is required.
The FPGAs are offered in either a 16-ball WLCSP package with a 0.35mm ball pitch and 1.409mm2 footprint, or a 36-ball BGA package with a 0.40mm ball pitch and 2.5mm2 footprint.
