Applications

SC5 standard cell technology targets legacy 5 V applications and high volume digital ASIC products. The low device cost accommodates designs requiring significant on-board memory, data path logic or IP blocks.

SC5 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. SC5 has extensive flight heritage.

Application
Mid-Range ASIC Design

SC5 provides a cost effective solution for mid-range applications with gate counts up to 1.6 million gates and up to 1.6 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 SC5 designs.

Application
FPGA Conversion

SC5 provides an ideal platform to cost reduce or replace obsolete 5 V PLD and FPGA devices, or even advanced FPGAs with suitable performance requirements. SC5 provides extensive support for FPGA memory and timing generator features, including live at power up (LAPU capability).

Application
Support for EOL Products

onsemi's FPGA-to-ASIC and ASIC-to-ASIC conversion capabilities allow SC5 to be a cost-effective, long-term solution for 5 V end-of-life products.

Application
Process Upgrade

onsemi ASICs designed in 1.25 μm, 1.0 μm, 0.8 μm, 0.6 μm processes, and any legacy 5 V core technology can be easily upgraded to the SC5 family. The onsemi ASIC library provides a common netlist design base.

Application
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.
