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 ON Semiconductor's domestic wafer fab. In addition ON Semiconductor 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.

SC5 also supports a wide range of applications in the industrial, communications, computing & peripherals and medical markets.

  • 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 ON Semiconductor RTL sign-off and netlist hand-off flows provide quick and seamless access for SC5 designs.
  • 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).
  • Support for EOL Products: ON Semiconductor'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.
  • Process Upgrade: ON Semiconductor 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 ON Semiconductor ASIC library provides a common netlist design base.
  • Adding Custom Blocks: ON Semiconductor 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.
