I think you mean the "8051" microcontroller. This is one of the longest lived 8 bit microprocessors built by Intel. Originally produced in 1980, this is an extremely capable processor well suited for many embedded applications.
Many other vendors now produce some flavor of 8051, often with many built-in capabilities such as serial ports, CAN, SPI, both volatile and non-volatile memory, etc.
