The P87C51RC2 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. Inaddition, an SFR bit (X2) in the clock control register (CKCON)also selects between 6-clock/12-clock mode.The devices are Single-Chip 8-Bit Microcontrollers manufactured in
