89C51/89C52/89C54/89C58 80C51 8-bit Microcontroller Family 4K/8K/16K/32K Flash

The 89C51 89C52 89C54 89C58 contain a non-volatile Flash program memory that is parallel programmable. For devices that are serial programmable (In-System Programmable (ISP) and In-Application Programmable (IAP) with a boot loader), see the 89C51Rx2 or 89C66x datasheets. All three families are Single-Chip 8-bit Microcontrollers manufactured in advanced CMOS process and are derivatives of the 80C51 Microcontroller family. All the devices have the same instruction set as the 80C51.
