DESCRIPTION
Three different Single-Chip 8-Bit Microcontroller families are presented in this datasheet:
FEATURES
· 80C32/8XC52/8XC54/8XC58 · 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.

· 80C51 Central Processing Unit · Speed up to 33MHz · Full static operation · Operating voltage range: 2.7V to 5.5V @ 16MHz · Security bits:
ROM 2 bits OTPEPROM 3 bits
· Encryption array 64 bytes · RAM expandable to 64K bytes · 4 level priority interrupt · 6 or7 interrupt sources, depending on device · Four 8-bit I/O ports · Full-duplex enhanced UART
Framing error detection Automatic address recognition
· Power control modes
Clock can be stopped and resumed Idle mode Power down mode
80C51FA/8XC51FA/FB/FC 0K/8K/16K/32K 256 Yes No
80C51RA+/8XC51RA+/RB+/RC+ 0K/8K/16K/32K 8XC51RD+ 64K 1024 Yes Yes 512 Yes Yes
· Programmable clock out · Second DPTR register · Asynchronous port reset · Low EMI (inhibit ALE)
The ROMless devices, 80C32, 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.
