NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section of this specification is not implied.
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maximum.
3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V_ss unless otherwise noted.


Description

Three different Single-Chip 8-Bit Microcontroller 8XC51FC families are presented in this datasheet:
*80C32/8XC52/8XC54/8XC58
*80C51FA/8XC51FA/8XC51FB/8XC51FC
*80C51RA+/8XC51RA+/8XC51RB+/8XC51RC+/8XC51RD+

For 8XC51FC families applications requiring 4K ROM/EPROM, see the 8XC51/80C318-bit CMOS (low voltage, low power, and high speed)
microcontroller families datasheet.

8XC51FC 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.

8XC51FC families provide architectural enhancements that make them applicable in a variety of applications for general control systems.
