The Intel 87C51FA/8XC51FB/8XC51FC is a single-chip control oriented microcontroller which is fabricated on Intel's reliable CHMOS III-E technology.
The Intel 83C51FA/80C51FA is fabricated on CHMOS III technology.
Being a member of the MCS 51 controller family, the 8XC51FA/8XC51FB/8XC51FC uses the same powerful instruction set, has the same architecture, and is pin-for-pin compatible with the existing MCS 51 controller products.
The 8XC51FA/8XC51FB/8XC51FC is an enhanced version of the 8XC52/8XC54/8XC58.
Its added features make it an even more powerful microcontroller for applications that require Pulse Width Modulation, High Speed I/O and up/down counting capabilities suc...
