Периферийный микроконтроллер P-51 фирмы Cybernetic Micro Systems

Cybernetic Micro Systems Peripheral 8051 System on a Chip

 

The P-51 "Peripheral 8051" is a new concept: An 8051 with built-in (E)ISA or PC-104 interface and supporting subsystems. These include downloadable Code RAM, dual port RAM, and all eleven IRQs to the host. Unlike classical 8051s, the P-51 naturally and easily interfaces to a host through simple standard buses, and its microsecond timing can provide real-time response to Windows applications.
