INTEGRATED CIRCUITS 8XC54/58 8XC51FA/FB/FC/80C51FA 8XC51RA+/RB+/RC+/RD+/80C51RA + 80C51 8-bit microcontroller family 8K–64K/256–1K OTP/ROM/ROMless, low voltage (2.7V–5.5V), low power, high speed (33 MHz) Product specification Replaces datasheet 8XC52/54/58/80C32 8XC51FA/FB/FC/80C51FA 8XC51RA+/RB+/RC+/RD+/80C51RA + of 1999 Apr 01 2000 Aug 07 Philips Semiconductors Philips Semiconductors 80C51 8-bit microcontroller family 8K–64K/256–1K OTP/ROM/ROMless, low voltage (2.7V–5.5V), low power, high speed (33 MHz) Product specification 8XC54/58 8XC51FA/FB/FC/80C51FA 8XC51RA+/RB+/RC+/RD+/80C51RA+ 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. All the devices have the same instruction set as the 80C51. These devices provide architectural enhancements that make them applicable in a variety of applications for general control systems.
