Copy Chip SAF-XC888CM-8FFI Binary

Copy Chip SAF-XC888CM-8FFI Binary from the memory and the program will be readout from flash and data will be readout from eeprom, unlocking microcontroller protective system will help to extract the firmware directly out from its memory;

The XC886/888 has the following features:

· High-performance XC800 Core

– compatible with standard 8051 processor

– two clocks per machine cycle architecture (for memory access without wait state)

– two data pointers

· On-chip memory

– 12 Kbytes of Boot ROM

– 256 bytes of RAM

– 1.5 Kbytes of XRAM

– 24/32 Kbytes of Flash;

24/32 Kbytes of ROM, with additional 4 Kbytes of Flash (includes memory protection strategy)

· I/O port supply at 3.3 V or 5.0 V and core logic supply at 2.5 V (generated by embedded voltage regulator)

Power-on reset generation

Brownout detection for core logic supply

On-chip OSC and PLL for clock generation

– PLL loss-of-lock detection

Power saving modes

– slow-down mode

– idle mode

– power-down mode with wake-up capability via RXD or EXINT0

– clock gating control to each peripheral

Programmable 16-bit Watchdog Timer (WDT)

Six ports

– Up to 48 pins as digital I/O

– 8 pins as digital/analog input

8-channel, 10-bit ADC

Four 16-bit timers

– Timer 0 and Timer 1 (T0 and T1)
