These devices can address up to 64 Kbytes of external program data memory
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 such as motor control
