The Intel 87C51FA is a single-chip control-oriented microcontroller which is fabricated on Intel"s reliable CHMOS EPROM technology. Being a member of the MCS-51 family, the 87C51FB/87C51FC uses the same powerful instruction set, has the same architecture, and is pin-for-pin compatible with the existing MCS-51 family of products. The 87C51FA is an enhanced version of the 87C51. The 87C51FB is an enhanced version of the 87C51FA. The 87C51FC is an enhanced version of the 87C51FB. With 8 Kbytes of program memory in the 87C51FA and 16 Kbytes of program memory in the 87C51FB and 32 Kbytes of program memory in the 87C51FC, it is an even more powerful microcontroller for applications that require Pulse Width Modulation, High Speed I/O, and up/down counting capabilities such as brake and traction control.
