P87C51FB
Description
Three different Single-Chip 8-Bit Microcontroller families are presented in this datasheet: 8XC54/8XC58 80C51FA/8XC51FA/8XC51FB/8XC51FC 80C51RA+/8XC51RA+/8XC51RB+/8XC51RC+/8XC51RD+ For applications requiring 4K ROM/EPROM, see the 8XC51/80C31 8-bit CMOS (low voltage, low power, and high speed) microcontroller families datasheet. All the families are Single-Chip 8-Bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 microcontroller family.
