世纪芯对IC解密中的过错攻击技术、硬件安全分析、安全保护位置的查找以及侵入式攻击与非侵入式攻击技术等等,拥有透彻的理解和丰富的实战应用经验。我们长期面向广大国内外客户提供各种类型芯片解密、单片机解密、IC解密能将解密成本和周期不断降低,并同时极大的确保解密的成功率。
The PIC14000 features include medium to high resolution A/D conversion (10 to 16 bits), temperature sensing, closed loop charge control, serial communication,and low power operation. The PIC14000 uses a RISC Harvard architecture CPU with separate 14-bit instruction and 8-bit data buses. A two-stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches,which require two cycles. A total of 35 instructions are available. Additionally, a large register set is included. PIC16/17 microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers.
Features:
The PIC14000 is a 28-pin device with these features:
· 4K of EPROM
· 192 bytes of RAM
· 22 I/O pins
The analog peripherals include:
· 8 external analog input channels, two with level shift inputs
· 6 internal analog input channels
· 2 comparators with programmable references
· A bandgap reference
· An internal temperature sensor
· A programmable current source
