Product Summary

The P87C51X2BA is an 8-bit microcontroller. The P87C51X2BA described in this data sheet is high-performance static 80C51 designs incorporating Philips high-density CMOS technology with operation from 2.7 V to 5.5 V. They support both 6-clock and 12-clock operation. The P87C51X2BA contains 128 byte RAM and 256 byte RAM respectively, 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits. In addition, the devices are low power static designs which offer a wide range of operating frequencies down to zero. Two software selectable modes of power reduction — idle mode and power-down mode — are available. The idle mode freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning.

Parametrics

P87C51X2BA 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.
