The PIC16F1847 is an 8-bit microcontroller that accommodates a wide power supply with a low power voltage range. The instruction set is fully PIC16F1847 compatible with the standard 8051. The PIC16F1847 contains a medium-term plan of 4K byte ROM (multi-time programmable disc), a 128-byte RAM, four 8-bit bidirectional addressable I\/O ports, and an additional 4-bit I\/O port for P4; 2 16-bit timer\/counter, a hardware watchdog timer and serial port.
PIC16F1847 Features: 12 interrupt priorities with four sources 4 output modes and TTL\/Schmidt triggers Optional port Programmable Watchdog timer Four channels 10-bit PWM (Pulse Width Modulator) One I2C communication interface (master\/slave) 8 keyboard interrupts input 256 in-chip RAM bytes LED drive capability (20mA) for all port pin low voltage detection interrupts and reset chips configured on RC oscillators (6MHz) with two 8-bit bidirectional ports and one 2-bit bidirectional port with two 16-bit timers\/counters for both analog comparators
Chip decryption, in simple terms, is to copy the stored code from the chip that has been encrypted. Chip decryption is also called chip decryption, single-chip decryption, single-chip decryption, IC decryption and so on.
Chip decryption method:
1. Software attacks.
2. Electronic detection attack.
3. Fault generation technology.
4. Probe technology.
etc
Chip decryption belongs to the legal edge of the industry, but with the strengthening of the patent concept and the strengthening of knowledge protection, the state has further standardized it. As a reverse technology research, chip decryption is to infer the original design theory from the finished product. If it is used for teaching, research, analysis, etc., it is not considered infringement. If the production and integration of another person's protected layout-design is copied solely for the purpose of business sale, it is considered an infringement.
