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.
The devices also 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.
The added features of the P87C51RA2/RB2/RC2/RD2 make it a
powerful microcontroller for applications that require pulse width
modulation, high-speed I/O and up/down counting capabilities such
as motor control.
