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) with a boot
loader), see the 89C51RC+/89C51RD+ datasheet.
Both 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.
