• Infinior - IMS16 series (Am186EM-compatible microcontrollers)
• Vadem - VG230 and VG330 (SoCs with NEC V30 CPU cores, manufacturing continued by Amphus)
• SiS - SiS 55x (SoCs with Rise mP6-based CPU cores; product line sold to DM&P, who rebranded it to Vortex86)
• Bandai - SPGY-1000 series (SoCs with 186-compatible NEC V30MZ CPU cores, used in the WonderSwan series of handheld game consoles)
• VAutomation - offered synthesizable x86 cores, in particular the Turbo 186, that has been implemented in ASICs from numerous vendors, e.g.
• Zoran Corporation: Vaddis 6
• Genesis Microchip Inc: GM1601
• Lantronix: DSTni-EX, DSTni-LX
• Synergetic: EC-1
• Pixelworks: PW164
• CAST — offered synthesizable x86 and x87 IP cores for use in ASICs and FPGAs, such as the C80186XL, C80187, and C387L.
• STMicroelectronics: STPC Atlas (486 core at up to 133MHz, embedded 2D graphics)

Open source x86 cores

• ao486 open source FPGA implementation of the 486SX (currently targets the Terasic Altera DE2-115)
