Cypress Semiconductor CY8C3866AXI-039, 8bit Microcontroller, CY8C3866AXI, 67MHz, 64 kB Flash, 100-Pin TQFP

PSoC 3 is a true programmable embedded system-on-chip, integrating configurable analogue and digital peripherals, memory, and a microcontroller on a single chip. The PSoC 3 architecture boosts performance through: 8051 core plus DMA controller and digital filter processor, at up to 67 MHz, Ultra low power with wide voltage range, Programmable digital and analogue peripherals enable custom functions, Flexible routing of any analogue or digital peripheral function to any pin PSoC devices employ a highly configurable system-on-chip architecture for embedded control design. They integrate configurable analogue and digital circuits, controlled by an on-chip microcontroller. A single PSoC device can integrate as many as 100 digital and analogue peripheral functions, reducing design time, board space, power consumption, and system cost while improving system quality.
