P87C51RC2BA

Product Summary

The P87C51RC2BA is a Single-Chip 8-Bit Microcontroller 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 P87C51RC2BA supports 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.

Parametrics

P87C51RC2BA absolute maximum ratings: (1)Operating temperature under bias: 0 to +70 or -40 to +85℃; (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 +6.0 V; (5)Maximum IOL per I/O pin: 15 mA; (6)Power dissipation (based on package heat transfer limitations, not device power consumption): 1.5 W.
