依托深圳本地良好的技术研发环境,世纪芯科技不仅在疑难解密领域倾注更多的研发资源,同时也在普通单片机低成本解密方案研究领域加大了投入,在技术攻关中成功研究出了EMC单片机、HOTEK单片机、CYPRESS单片机、MXIC单片机等单片机类型的超低成本解密方案,为芯片解密行业的整体发展作出了突出贡献。
PIC18C242芯片特点:
High Performance RISC CPU:
·C-compiler optimized architecture/instruction set
- Source code compatible with the PIC16CXX instruction set
·Linear program memory addressing to 2M bytes
·Linear data memory addressing to 4K bytes
·Up to 10 MIPs operation:
- DC - 40 MHz osc./clock input
- 4 MHz  - 10 MHz osc./clock input with PLL active
·16-bit wide instructions, 8-bit wide data path
·Priority levels for interrupts
·8 x 8 Single Cycle Hardware Multiplier
Peripheral Features:
·High current sink/source 25 mA/25 mA
·Three external interrupt pins
·Timer0 module: 8-bit/16-bit timer/counter with 8-bit programmable prescaler
·Timer1 module: 16-bit timer/counter
·Timer2 module: 8-bit timer/counter with 8-bit period register (time-base for PWM)
·Timer3 module: 16-bit timer/counter
·Secondary oscillator clock option - Timer1/Timer3
·Two Capture/Compare/PWM (CCP) modules. CCP pins that can be configured as:
- Capture input: capture is 16-bit, max. resolution 6.25 ns (TCY/16)
- Compare is 16-bit, max. resolution 100 ns (TCY)
- PWM output: PWM resolution is 1- to 10-bit.
Max. PWM freq. @:8-bit resolution = 156 kHz
10-bit resolution=  39 kHz
·Master Synchronous Serial Port (MSSP) module.
Two modes of operation:
- 3-wire SPI(supports all 4 SPI modes)
-I2C master and slave mode
·Addressable USART module:
- Supports interrupt on Address bit
·Parallel Slave Port (PSP) module
