89C54 80C51 8-bit microcontroller family 4K/8K/16K/32K Flash

89C54 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) with a boot loader), see the 89C51RC+/89C51RD+ datasheet. Both families are Single-Chip 8-bit Microcontrollers manufactured in.
