Product Summary

The P87C51RB+4A is an 8-bit microcontroller. For applications requiring 4K ROM/EPROM, see the P87C51RB+4A 8-bit CMOS (low voltage, low power, and high speed) microcontroller families datasheet. All the families are Single-Chip 8-Bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 microcontroller family. All the P87C51RB+4A has the same instruction set as the 80C51. The P87C51RB+4A provides architectural enhancements that make them applicable in a variety of applications for general control systems.

Parametrics

P87C51RB+4A absolute maximum ratings: (1)Operating temperature under bias: -55 to +125 ℃; (2)Storage temperature range: -65 to +150 ℃; (3)Voltage on EA/VPP pin to VSS: 0 to + 13.0 V; (4)Voltage on any other pin to VSS: -0.5 to VDD+0.5V V; (5)Maximum IOL per I/O pin: 20 mA; (6)Power dissipation (based on package heat transfer, not device power consumption): 1.5 W.

Features

P87C51RB+4A features: (1)Extended features of the 51MX Core:; (2)23-bit program memory space and 23-bit data memory space linear program and data address range expanded to support; (3)up to 8 Mbytes each; (4)Program counter expanded to 23 bits; (5)Stack pointer extended to 16 bits enabling stack space beyond the 80C51 limitation; (6)New 23-bit extended data pointer and two 24-bit universal pointers greatly improve C compiler code efficiency in using; (7)pointers to access variables in different spaces.; (8)100% binary compatibility with the classic 80C51 so that existing code is completely reusable; (9)Up to 24 MHz CPU clock with 6 clock cycles per machine cycle; (10)96 Kbytes or 64 Kbytes of on-chip OTP; (11)3 Kbytes or 2 Kbytes of on-chip RAM; (12)Programmable Counter Array (PCA); (13)Two full-duplex enhanced UARTs; (14)Industry-standard Serial Peripheral Interface (SPI).
