Datasheet - PSoC® 3 CY8C34 Programmable System-on-Chip

2020 年 7 月 06 日


PSoC® 3 is a true programmable embedded system-on-chip, integrating configurable analog and digital peripherals, memory, and a microcontroller on a single chip. The PSoC 3 architecture boosts performance through:

  • 8051 core plus DMA controller at up to 50 MHz
  • Ultra low power with industry's widest voltage range
  • Programmable digital and analog peripherals enable custom functions
  • Flexible routing of any analog or digital peripheral function to any pin

PSoC devices employ a highly configurable system-on-chip architecture for embedded control design. They integrate configurable analog and digital circuits, controlled by an on-chip microcontroller. A single PSoC device can integrate as many as 100 digital and analog peripheral functions, reducing design time, board space, power consumption, and system cost while improving system quality.
