87C554 Datasheet (NXP) - 80C51 8-bit microcontroller

87C554, 80C51 8-bit microcontroller

This data sheet describes the 6 clock version of the 8xC554.

This device is only available in 64L LQFP.

The 8xC554 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family.

The 87C554 has the same instruction set as the 80C
