NXP Semiconductors 80C528
the 80C51 microcontroller family. The 8XC528 has the same instruction set as the 80C51. The idle mode freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning.| Part No. | 80C528 |

DESCRIPTION
The 8XC528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. Three versions of the derivative exist: ROM multi-source, two-priority-level, nested interrupt structure, two serial interfaces (UART and I2C-bus), and on-chip oscillator and timing circuits. In addition, the 8XC528 has two software selectable modes of power reduction — idle mode and power-down mode. The power-down mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative.FEATURES
