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. ROM/EPROM Memory Size (X by 8) RAM Size (X by 8) Programmable Timer Counter (PCA) 80C31/8XC51 0K/4K 128 No 8XC54/58 0K/8K/16K/32K 256 No 80C51FA/8XC51FA/FB/FC 0K/8K/16K/32K 256 Yes 80C51RA+/8XC51RA+/RB+/RC+ 0K/8K/16K/32K 512 Yes 8XC51RD+ 64K 1024 Yes Hardware Watch Dog Timer No No No Yes Yes The ROMless devices, 80C51FA, and 80C51RA+ can address up to 64K of external memory. All the devices have four 8-bit I/O ports, three 16-bit timer/event counters, a multi-source, four-priority-level, nested interrupt structure, an enhanced UART and on-chip oscillator and timing circuits. For systems that require extra memory capability up to 64k bytes, each can be expanded using standard TTL-compatible memories and logic. 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. It also has a more versatile serial channel that facilitates multiprocessor communications.
