P87C51RA2_RB2_RC2_RD2
80C51 8-bit microcontroller family 8KB/16KB/32KB/64KB OTP, 512B/512B/512B/1KB RAM, low voltage (2.7 to 5.5 V), low power, high speed (30/33 MHz)

80C51 8-bit microcontroller family 8KB/16KB/32KB/64KB OTP, 512B/512B/512B/1KB RAM, low voltage (2.7 to 5.5 V), low power, high speed (30/33 MHz)

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.
