PHILIPS 8XC52/54/58/80C32 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
The Philips 8XC51/8XC52/8XC54/8XC58/80C32 series are single‑chip 8‑bit microcontrollers built in an advanced CMOS process. They operate at low voltage (2.7 V – 5.5 V), provide high speed up to 33 MHz, and offer a range of memory options from 8 KB to 64 KB ROM/EPROM, 1 KB OTP/ROMless and up to 1 KB RAM.
Key features include four 8‑bit I/O ports, three 16‑bit timer/counter units, a four‑level priority interrupt system, a full‑duplex enhanced UART, and optional power‑saving modes such as idle and power‑down. Pin‑out diagrams, pin descriptions and package information for DIP, LCC and QFP variants are provided.
The datasheet also lists electrical characteristics, security bits, and application notes, and it contains legal and disclaimer statements from Philips Semiconductors.
