P89C58UBPN Datasheet PDF - Philips

●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.
