Philips Semiconductors
DESCRIPTION
The devices are Single-Chip 8-Bit Microcontrollers manufactured in
an advanced CMOS process and are derivatives of the 80C51
microcontroller family. The instruction set is 100% compatible with
the 80C51 instruction set.
The devices support 6-clock/12-clock mode selection by
programming an OTP bit (OX2) using parallel programming. In
addition, an SFR bit (X2) in the clock control register (CKCON)
also selects between 6-clock/12-clock mode.
These devices have either one or two I
handling speeds up to 400 kbits/s (Fast I
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.
The added features of the P8xC66xX2 make it a powerful
microcontroller for applications that require pulse width modulation,
high-speed I/O, I
capabilities such as motor control.
