P87C51RA2/RB2/RC2/RD2
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. T h e devices support 6-clock/12-clock mode selection by p r o g r a m m i n g an OTP bit (OX2) using parallel programming. In a d d i t i o n , an SFR bit (X2) in the clock control register (CKCON) a l s o 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.
