PIC 单片机为美国微芯公司(MI—CROCHIP)公司生产研发,品种极其丰富,各系列片内功能资源各不相同,可以满足用户不同层次的开发要求。它采用哈佛总线结构和精简指令集(RISC)技术,其寻址方式简单、运行速度快、功耗低、驱动能力强等。在 MICROCHIP 公司 PIC 系列产品里,有低档、中挡、高挡单片机,且大部分都带有 USART、SPI、IIC 等总线接口,有的甚至还带有 USB 和 CAN 模块。这些特点给开发者带来了很大的方便。
PIC microcontroller for the United States Microchip Company (MI-CROCHIP) company R & D, extremely rich variety, each series of different functional resources within the chip, to meet the development needs of users at different levels. It uses Harvard bus architecture and reduced instruction set (RISC) technology, its addressing method is simple, fast, low power consumption, strong driving ability. MICROCHIP company PIC series products, there are low, medium, high-block MCU, and most of them with USART, SPI, IIC bus interface, and some even with USB and CAN module. These features bring great convenience to developers.
