    P87C51RD2BA 8 Bit Computer IC Chip 8051 87C Microcontroller 33MHz 64KBOTP 44-PLCC

    P87C51RD2BA Computer IC Chip 8051 87C Microcontroller IC 8-Bit 33MHz 64KB (64K x 8) OTP 44-PLCC


    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.


    • 80C51 Central Processing Unit – 8 kbytes OTP (87C51RA2) – 16 kbytes OTP (87C51RB2) – 32 kbytes OTP (87C51RC2) – 64 kbytes OTP (87C51RD2) – 512 byte RAM (87C51RA2/RB2/RC2) – 1 kbyte RAM (87C51RD2) – Boolean processor – Fully static operation – Low voltage (2.7 V to 5.5 V at 16 MHz) operation

    • 12-clock operation with selectable 6-clock operation (via software or via parallel programmer)

    • Memory addressing capability – Up to 64 kbytes ROM and 64 kbytes RAM

    • Power control modes: – Clock can be stopped and resumed – Idle mode – Power-down mode
