INTEGRATED CIRCUITS 80C528/83C528 CMOS single-chip 8-bit microcontroller Product specification IC20 Data Handbook 1995 Feb 02 Philips Semiconductors Philips Semiconductors Product specification CMOS single-chip 8-bit microcontrollers 80C528/83C528 DESCRIPTION The 8XC528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 8XC528 has the same instruction set as the 80C51. 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.
