89C51/89C52/89C54/89C58

80C51 8-bit microcontroller family

4K/8K/16K/32K Flash

1999 Oct 27

853–2148 22592

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.
