INTEGRATED CIRCUITS 87C652/87C654 80C51 8-bit microcontroller 8K/16K, 256 OTP, I2C Product specification Replaces data sheets 87C652 of 1998 May 01 and 87C654 of 1998 May 01 IC20 Data Handbook 1999 Jul 23 Philips Semiconductors Philips Semiconductors 80C51 8-bit microcontroller 8K/16K, 256 OTP, I2C Product specification 87C652/87C654 DESCRIPTION The 87C652/87C654 single-chip 8-Bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C652/87C654 has the same instruction set as the 80C51. Three versions of the derivative exist: 80C652—ROMless 83C652/83C654—8 Kbyte, 16 Kbyte ROM 87C652/87C654—8 Kbyte, 16 Kbyte OTP The ROMless and ROM are in separate datasheets. This device provides architectural enhancements that make it applicable in a variety of applications for general control systems. The 87C654 contains a non-volatile 16k × 8 EPROM and the 87C652 contains an 8k x 8 EPROM. Both have a volatile 256 × 8 ...
