Atmel 8051 MCU Attack
Atmel offers a broad range of microcontrollers based on the 8051 architecture ranging in code density from 2K bytes to 128K bytes. The product line includes 8-bit microcontrollers based on the powerful, low-power Single-Cycle AT89LP core as well as MCS-51® industry standard socket drop-in devices and small footprint 14/16/20/28-pin derivatives, all manufactured in advanced Flash technologies (see on-line selection table). Most members in this product line include ISP (In-System Programming) capability, while some also support the high-speed (X2) mode which doubles the internal clock frequency for CPU and peripherals upon user selection.
With the widely used of 8051 microcontrollers, the 8051 MCU Code Extraction technology has made significant development. We can extract code from MCU for our customers(only for lawful research purposes), part of the Atmel 8051 MCU Attack is as follows
