DESCRIPTION
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.
