ONC18 wafers are produced in onsemi's domestic wafer fab. In addition onsemi offers a complete on-shore flow including design, mask generation, silicon, packaging, and test complete with ITAR and NOFORN processing to support government and military programs. As a result, ONC18 is a perfect fit for military and commercial avionics, military munitions and radar systems. Other application focuses include industrial applications, commercial and military communications including wireless infrastructure and other end applications.

The small die size and low device cost accommodates designs requiring significant on-board memory and logic. The high performance capabilities of the process make ONC18 ideal for many applications, including those requiring 10/100 Ethernet MAC, CAN 2.0 and I2C.

Low power core libraries and memories allow ONC18 to meet power-sensitive ASIC requirements. Coupled with onsemi's on-shore capabilities, ONC18 is a strong solution for battery powered and secure applications in a wide range of harsh environments. ONC18 provides a cost effective solution for mid-range applications with gate counts up to 10 million and up to 7 million bits of memory. Combined with support for a rich family of I/O standards, the onsemi RTL sign-off and netlist hand-off flows provide quick and seamless access for ONC18 designs.

Second Source for Existing Products

The ASIC-to-ASIC conversion capability from onsemi allows ONC18 to be a cost-effective alternative supply for existing high, medium and even low-volume products.

FPGA Prototype Designs

Based on the extensive experience of onsemi with FPGA conversions, ASIC designs prototyped in FPGAs, or those which are partially prototyped or partitioned between FPGAs and other devices, can be integrated into a single ONC18 device.

FPGA Conversion

The ONC18 product roadmap will be expanded to offer full support for 1.8 V and 1.5 V FPGA devices, including full I/O and memory feature compatibility and DLL/PLL equivalence.

Adding Custom Blocks

onsemi specializes in combining digital and analog functions in custom ASICs. Analog functions include ADCs and DACs, op-amps and comparators, EMI/RFI filters, AC-DC and DC-DC controllers and regulators, drivers, thermal management, voltage and current management, and digital potentiometers.
